Testing – a new chain wheel and the Akatarawa Road


The Folding Goldies’ suggestion of cycling the Akatarawa Road for our next ride, and my misgivings about the hill climbs, got John thinking of how he could modify the gearing on my bike so that it would make it easier for me to bike uphill.

So he had a chat to Francis at Johnsonville Cycles and got the necessary bits. Then he spent a fair few hours in the garage tinkering. In essence, he has replaced the 52-tooth chain wheel with a 39-tooth one, which gives me greater leverage in the lowest gear, i.e. more oomph to get up the hill! But I’ll let John describe the details of what he did at the end of this post (or you can look at his website. You’ll have to scroll down to the last three paragraphs of the Technical Details section).

I had the first try of the modification on the steep dead-end road round the corner from where we live. It seemed reasonably OK to get to the top of the hill, but the bike was making some noises. John doesn’t like it when mechanical things make noises they shouldn’t, so more time was spent in the garage to remedy that. So far, so good.

The next thing to check out was the gradient and condition of the Akatarawa Road.  Since it was fine last Tuesday, we drove to Upper Hutt, and headed up the Akatarawa Road (in the car, not on the bike!). Much of it is very tortuous, with lots of twists and turns, and lots of “blind corners”. On the whole the inclines do not seem too bad, as they are short-ish, and interspersed with dips or flat stretches. And the surface is good. But the road is quite narrow. There is only just enough room for two cars to pass each other, and there is no shoulder for a cyclist to get out of the way in a hurry. I must admit that this aspect of the road worries me. What would be the chances of getting hit by a car coming up behind you around a blind bend? Then again, there is very little traffic. We met only three cars during the whole trip.

But there were dozens of cars at Staglands that got there before us. This is the first week of the school holidays – as we found out when we got to Staglands. We pulled into the carpark and had trouble finding a spot. There were two big buses – one of the drivers informed us that the passengers had been children on a school holiday programme. The valley was ringing with excited children’s voices and the calls of birds of various descriptions (peacocks, geese, tui, chickens). I hoped the kids and their minders would not all be in the café where we were planning to have lunch.

It was after 1pm, so it was relatively quiet in the café. We sat out on the deck, near a tree that was labelled “Native Bird Feeding Station”, and lots of little wax-eyes and a tui or two came to feed from a container that contained a milky-looking liquid.

Staglands is about 16 km from Upper Hutt, then it is another 4 km to the highest point – probably the most testing uphill bit. The downhill stretch to Reikorangi is quite steep, and there is a drop on the left side of the road – you can’t afford to lose concentration, lest you tip over the edge. It will require a firm grip on the brakes too, I think, as I’m not game to go hurtling down at full speed.

When we got to Waikanae, we decided to try the bike out some more by cycling the Waikanae River track loop. We parked near the estuary, and headed up the north bank. We had gone only a couple of kilometres, when the chain of my bike fell off. John restored it, but it fell off again after the first couple of pedal strokes. This happened several times, much to John’s frustration. He tried taking off the new chain wheel and turning it around (outside-in), hoping to improve the chain line. That did not solve the problem. In the end he discovered what was going on: one of the chain plates was splayed, which caused the chain to keep falling off.

Trackside bike repairs

Out came the full toolkit, but what he needed – a pair of pliers – was not in it. What to do? Squeezing it by hand did not work, banging it didn’t either, but in the end, with the help of a rock and a spanner, he managed to coerce it into the correct shape, and hooray! the chain stayed put, and we were able to continue on our way.

There were quite a few people on the track, and families having picnics on the little beaches. We saw a trio of cyclists – two by the water’s edge taking their shoes off, and one emerging from the bushes – so I reckoned that they’d gone for “a pedal, a piddle, and a paddle”.

We crossed the SH1 bridge, and made our way down the southern bank of the river. We stopped to take off a layer, as it was getting quite warm. In the photo below, you can see the difference in the size of the chain wheels on our bikes (click on the photo to enlarge it).

A bit further along we saw some ostriches in a paddock. I wanted to take a picture of them, and here I discovered what was wrong with my camera (it had misbehaved during our last ride). It was the zoom that didn’t work. The camera must have been knocked inadvertently, as there were a couple of small dents in the lens surround. Darn!

Apart from the problem with the chain falling off, it was a very pleasant 12 km ride. But John spent more time in the garage that evening to deal to the errant chain. And today (Friday), he removed a link from it. So we had to go and give the bike another try.

We drove out to Plimmerton, from where we biked up the hill to Pukerua – the hill that had defeated me a few weeks ago. That day there had been a slight southerly, which probably helped me up the hill to nearly, but not quite, the top. Today though, there was a near-galeforce northerly, i.e. a fierce headwind as you go uphill. It would be as good a test as any.

I made it to the top without having to step off! Yay! I won’t say it was easy – but it was easier than before. The new chain wheel had definitely made a difference.


I made it! (photo by John)

The downhill, of course, was a blast! Not only did I not have to pedal at all, but we were being pushed along by the tailwind. I did find it a bit disconcerting that once at the bottom of a downhill, and starting to pedal again, in top gear, I had nothing to “push against”. John said that this was the trade-off for having the different gearing. Well, so be it. I think that with this change, I will probably do OK on the Akatarawa Road ride in a few weeks’ time.

I asked John to write about the technical details of the changes he made to my bike.

Technical details – by John Patterson

In cycling most people have a comfortable gear which they use often. Ideally, this should be in the middle of the available range. With our bikes, that range is limited to a factor of two, when three would be ideal.

With difficulties in hill climbing the simplest way to help is to reduce the size of the chain wheel. The chain needs to be shortened to compensate. The number of inches to remove from the chain should be approximately:

(old chain wheel teeth – new chain wheel teeth)/4

Another inch may be required if smooth running is not obtained.

I replaced the 52-tooth chain wheel on Désirée's bike with a 39-tooth chain wheel. Therefore I needed to remove (52–39)/4 or 3.25 inches from the chain. In order for the chain to join up, only whole inches can be removed. I started with three inches, or six half-inch links.

My old chain tool was not very good as it was hard to get the pin and plate set right when joining up. This caused the chain to come off later, when running in the highest gear. A new Park multi-tool fixed that.

In the lowest gear, the top derailleur wheel also conflicted with the largest cog, which made a rumbling noise. As the chain is shortened, this top wheel moves in an arc upwards and then downwards. Adding an inch to the chain made it too loose in high gear. The final solution was to remove four inches of chain.

Longer term, a 44-tooth chain wheel would be ideal. In that case, two inches of chain would need to be removed.

The gear range is now from 27.2 to 54.5 gear inches, or 2.17 to 4.35 metres development, or a 2.03 to 4.07 gain ratio. The lowest gear is the same as that on my Jamis Allegro road bike. The highest gear is now similar to the set-up found on some single-speed commuter/shopping bikes. (An explanation about gear ratios can be found here.)

I also added a recycled BMX chain guard as shown below. These chain guards don't have the "right look" for BMX cyclists, so they are often removed from new bikes before sale. Enough room was left to allow a larger chain wheel to be fitted.

About the bikes

I have just done a whole lot of "fiddling" with my blog. I have added a list of Keywords along the left side of the page to facilitate finding topics of interest. I have also shifted a few entries that were in the "Other Stuff" page to the main page, even though they are not about cycling, but about some of my other interests.

On John's suggestion that some technical information might be of interest to some people, I am adding below a pared-down extract from his webpage, about the Giant Expressway 2 Folding Bike. This also allows me to add some useful technical keywords to the list.

Giant Expressway 2 Folding Bike (by John Patterson)

 

Introduction


The Giant Expressway 2, 2013 folding bike is the latest folding bike from Giant. The bike is intended for commuting, where a larger bike might not be permitted on peak hour public transport. The bike is also ideal as a means to explore new places, and to get fit. There are many suitable cycle trails and tracks here in New Zealand.

I purchased this bicycle as an easy re-introduction to cycling. I got it at Burkes Cycles for $560 which was a standard discount from the retail price of $599. This price to that of a good quality conventional bike so a decision can be made purely on personal needs.

I had not cycled for 13 years because of health issues. The folding bike was perfect as I could put it in the car and take it to somewhere flat to ride. Now that my fitness has improved, I have started using the folding bike for longer rides. It deals well with variable surfaces – I have had no problems with riding it on gravel.

I bought Désirée a bike so she can join me on the rides. Both bikes can easily fit inside our small Nissan Micra car with room to spare for luggage when travelling further afield.

 Technical details


The components are basic, but sufficient for most applications. So far I have had no problems. The Expressway wheels are quite strong with 36 stainless steel spokes, alloy rims, alloy hubs, and solid axles. Other good points are a Cr-Mo fork, a hydroformed 6061 aluminium alloy frame and a substantial carrying bag. Specifications are available from any Giant web site or dealer.

The bike has a wide range of quick release adjustments for seat height, handlebar height and tilt. Other settings for gears and brakes are finger adjustable. Horizontal seat position, and some other brake adjustments, require a 5 mm allen-key. Wheel removal requires, preferably, a 15 mm ring spanner. Quick releases are not required as the bike fits in a car without removing any wheels. If you have a good local bike shop then none of this will be a worry.

The bike has seven speeds ranging from 70 to 35 Gear-Inches, 5.6 to 2.8 Metres-Development or a 5.24 to 2.62 Gain-Ratio. These terms are defined here. In other words, the lowest gear requires half the effort of the highest gear. Here in Wellington, New Zealand, I can climb most hills with these gear ratios. I can always walk if things get too difficult.

The geometry of the bike has similarities to the classic, and well regarded, Raleigh 20 folding bike. Both bikes have a larger rear triangle than most folding bikes sold today. This strengthens the support for the seat post and the more heavily laden rear of the bike. The seat post is supported, in 4 distinct places, rather than in just the 2 places found on many other folding bikes. The Expressway wheel base is 1013 mm, while the Raleigh 20 wheel base is 1003 mm. The shortest distance from the seat-post axis to the handle-bar axis is the same at about 570 mm. The seat-post and head-tube angles are similar at about 71 degrees. The Expressway chain-stay length is 404 mm while the Raleigh 20 chain-stay length is about 392 mm.

Improvements


I was told that I could not fit a standard carrier on this bike. In fact it was easy to fit, so both bikes now have carriers. They are set back far enough to take my old pannier bags, if needed. I have mounted a small pump under the carrier.

A Cateye bar-end mirror was fitted to each bike. This addition is probably the most important as it contributes to safety. You can see the line that traffic is taking behind you, whether any indicators are flashing, and the approach of other cyclists. I have used a bar-end mirror on my mountain bike since the late 1980s. When riding on busy roads it helps me to assess the space that wide vehicles, such as trucks, would leave me. I filed some plastic off the inside of the end-cap so the mirror tilts out further. This prevents it being knocked by my hand during rides.

On each bike I was able to fit a holder for a 600 ml drink bottle behind the seat, attached to the carrier and its support-stay. The bottle holder tabs were bent slightly to fit and a single 5 mm hole was drilled in the carrier. The triangle thus formed made the carrier-stay more rigid as well. I did not like supporting the bottle horizontally on the frame, in front of the rider as it interferes with stepping over the frame to ride or to dismount.

I purchased two Cateye Velo 5 bike computers so we can each keep track of the distance travelled. This basic model has trip distance, odometer, maximum speed and a clock. The Velo 8 offers more options, including average speed.

I had some old Lowepro camera bags which were easily mounted on the front handle bars. They can contain items such as locks, sun-glasses, cameras and tire repair kits. These bags have pull-out rain covers.

On my bike I replaced the saddle with one with longer mounting rails and better comfort. This allowed me to set the saddle back further so that the set-up was similar to my mountain bike. On Désireé's bike I also replaced the saddle with a more comfortable one.

I have a basic LED lighting set-up for emergencies. I don't anticipate cycling at night.

Tyres


For reference, the Kenda Kwest 20x1.25 inch tyre, fitted on the Giant Expressway 2, is actually 480 mm or 18.9 inches in diameter. The circumference is therefore 1508 mm or 151 cm. The last value should be entered when the bike computers are set up. The measured tyre width is actually 1.39 inches or 35 mm, when inflated. In the front, the tyre clearance is an average of 13.5 mm on each side. In the rear, it is about 6.3 mm on each side.

There appears to be little relationship between the specified and the actual tyre dimensions on many bikes. This means that any upgrading is essentially an experiment. The frame clearance from the tyre wall should not be much less than 3 mm. This maximum measured width of a substitute tyre should therefore be no more than 56 mm in the front and 42 mm in the rear. The particular internal width of the rim can affect the measured tyre width and place limits on the maximum tyre width that can be safely fitted.

After experiencing a few punctures I upgraded to Kenda 912 20x1.75 inch tyres. They ride better on rough surfaces and they also have a good tread pattern for the road. The new tyres are 3.3% larger in diameter so a tyre circumference of 156 cm needs to be used with the bike computer. The chain-stay clearance is about 2.5 mm. Note that the Giant tyre specification is wrong in New Zealand. Here, Kenda 20x1.25 inch tyres are supplied instead of the specified 20x1.75 inch tyres.

Maintenance


The maintenance required on this bike is similar to any other. Keeping the chain clean and lubricated is important. I first use some light oil to penetrate inside the chain. I wipe off the outside of the chain and then I apply some dry lubricant.

On Désirée's bike I removed one shim from the freewheel cassette, as it was a little loose and noisy when ridden. This is a low cost item so replacement is an alternative. The shim removal stopped the noise by reducing the bearing clearance. The cover recently worked loose because I did not tighten it up enough when I refitted it. Using a punch I have tightened it up more firmly. I also used blue loctite 243 threadlocker to assist.

Learning to adjust the derailleur will help to keep the bike running smoothly. It is a simple twist adjustment on the derailleur end of the cable housing. The cable can stretch slightly with time or the cable housing may shorten. To compensate, the adjustment is turned while pedalling the bike by hand, in a middle gear. You may need help to support the rear of the bike off the ground, or you could turn the bike upside down. Adjust for minimum chain noise. Excessive noise means that the derailleur is trying to move the chain out of alignment. Your local bike shop can help.

The brakes may also need adjusting as the brake-pads wear. In this case the adjustment is on the brake lever.

I carry some spares and safety equipment on our trips. This includes a spare tube, a tyre repair kit (including patches and tyre levers), a 15 mm ring spanner, a bike multi-tool, light rainwear, a sun hat, a basic first aid kit, a torch, a lock, a small tripod and a tiny folding kite. We always take water, a sliced apple and some small chocolate bars. I usually have a locality map on my iPod Touch. We both carry cell phones. I keep a larger tool-kit and lubricants in the car.

Conclusion


The bikes are performing well. As I have gained fitness, the urge to upgrade the gearing has dissipated. Much of the recreational cycling, in the first half of last century, including round the World trips, was done by people using 1 or 3 speed gearing. The 3 speed bikes also had less than half the gearing range I have now. I see no need to substitute higher grade bike components for our application.

I have found that off-road loose surface riding is a good way to gain bike handling skills.

When cycling recently in New Plymouth we discovered that the bikes are good in the rain. The carrier, added at the rear, provides spray protection from the rear wheel. The small wheel size at the front means the feet don't get as wet as they do on a standard bike.

The folding bike has provided me with a pleasant way to improve my health. The gains have been significant. In addition, I have been able to explore many areas in my own city that are new to me.

Petone Foreshore and Pottery Exhibition


Last Thursday (26 September) was a busy day. In the morning I went to visit my sister’s pottery exhibition in the Thistle Hall Gallery at the top of Cuba Street. And in the afternoon John and I went for a 27 km bike ride along Petone Foreshore and up the Hutt River trail. Then in the evening I went to my regular Scottish Country Dance club night. So by the end of the day, the old undercarriage (feet, knees and thighs) ached a bit.

My sister, Aimée McLeod, is a well-respected, professional Wellington potter. She has been potting for over twenty years. She first learned her craft in Japan, and has a Certificate of Craft Design (a two-year course) from Whitireia Polytechnic, and a Diploma of Art (Ceramics) – four years part-time by “distance mode” – from Australia National University, Canberra.

“Amaze/Aimée’s" Pottery Exhibition in the Thistle Hall Gallery

The exhibition is titled “Amaze/Aimée’s” – a play on words, as the two words are pronounced the same. One of Aimée’s bugbears is that her name is often mispronounced as “Amy”. It is a French name, which should be pronounced “Emmay” or like the initials “MA” (as for the degree Master of Arts).

Aimée’s work is very versatile, ranging from domestic ware – cups, mugs, plates, bowls; to decorative platters – some with carved details inspired by Polynesian designs, some with just awesome glazes; to large hand-built sculptural creations.

I love the colours in this platter

The exhibition is on until 3pm on Sunday 29 September. If you’ve missed it, you can still see her work at her Open Studio Sale Weekend on 23 and 24 November. She also has a stall at the Thorndon Fair in early December. A very good place to start for your Christmas shopping! Check out Aimée’s website here.

While I was at the Thistle Hall Gallery, I held the fort for half an hour, so that Aimée could run an errand. During this time, I had a phone call from John suggesting we should go for a bike ride since it was a beautiful day. So as soon as Aimée was back, I tootled off home, to scoff a quick lunch before going out again. BUT, once home, I discovered I still had the gallery key in my pocket. What a dope! So we had to return it before we could go on our ride.

We decided to ride along the Petone Foreshore, and to carry on up the Hutt River trail. We have ridden both those areas before, so we didn’t spend too much time stopping and taking photographs. We wanted to get a good few kilometres under our belt. Still, there are always sights or views which merit a photo.

Right at the start of the foreshore, there is a gravel path between the beach and the road. A nice place to take a walk, with places to sit at intervals.

A nice place to enjoy the sun. The Petone Wharf is in the background (photo by John)

Soon the track petered out and we rode on the wide Esplanade foot/cycle path. Near the Rowing Club there is a weathervane in the shape of a flying fish, on top of a post. When we started our ride, the wind was coming from the south. By the time we came back this way, the vane had turned, as the wind was coming from the north-west.

At the end of the foreshore, the path goes around the point at the mouth of the Hutt River. Then the narrow gravel track leads through a small park, to end up just before the Waione Street Bridge. There is a signpost pointing the way to the “Estuary Boardwalk”, along the wetlands below the road. John ventured down there, but as it was narrow and winding, and without edges – a sure recipe for a mishap, I thought – I chickened out and kept going on the footpath towards the bridge.

The track carries on under the bridge and beyond, but John only followed it for a short distance. He ended up walking, as biking was a bit dodgy – just as I thought it would be. Then to get back to the road, where I was waiting for him, before the bridge, he had to carry his bike up the steps.

John had to carry his bike up the steps

Once across on the other side of the river, we looped back to the track that goes under the bridge, to follow the Hutt River Trail. This is a lovely smooth path, and one can pick up a bit of speed (I’m getting good a this now!).

There is a place where the river appears to split into two streams. I wondered whether there might be a sidestream joining the river, but we could see no evidence of that. There is a finger of land, pointing downstream, with a culvert at the top end which probably has the function of diverting some of the water, when the level gets too high. It looks like the water level at the top of the finger is higher in the river than in the sidestream.

A ‘finger’ of land. Note the difference in water level at the top of the finger (photo by John)

A bit further along, the path goes under a railway bridge, and as we were going under it, a train came chugging very slowly over it. I think it was going so slowly because some maintenance people were working on it.

The train chugged very slowly across the bridge

The track meanders along the river’s edge, and evidence that spring is definitely here is showing in the fully greened-up willows. In some places the gravel track had muddy patches and puddles, as we'd had a few days of heavy rain earlier in the week.

Freshly mown grass and green willows – Spring! (photo by John)

When we had covered 13kms, we were at the level of Fraser Park, and here we decided to cross the road, to get onto the smooth cycle path on the top of the stopbank for our return trip, and thus avoid the puddles and mud. Near the former TV studios at Avalon, the rain had left rather large puddles in the sportsfield behind the stopbank, which seemed to have attracted the local seagull population.

The seagulls liked the puddles left after several days of heavy rain (photo by John)

From here we continued without stopping until we got back to Petone. And as the path was smooth and flat, I ventured into using my sixth and seventh gears, which, so far, I hadn’t actually used. My bike has seven gears, and after a discussion some days earlier about the merits of seven versus 21 gears, I thought I should try using my higher gears.

It was a revelation, an epiphany! I discovered that I was able to cover more ground, in less time, for less effort! What a thrill! I was flying along. I was actually able to keep up with John!

Now most cyclists worth their salt will probably be scathing about how dumb I am. How could anyone not know that? Well, my excuse is that I am not mechanically minded, and I’d never stopped to think it through. Duh!

I asked John why he’d never mentioned it, and his reply was “Well, some things you should discover for yourself”. Gee, thanks a lot, John!

Actually, he has tried to explain how gears work – many, many times, he says – but my mind switches off when he comes over all scientific. And really, in the back of my mind, I did know and understand the relationship between little cogs and big cogs, etc. I just never applied that to biking or to the amount of effort needed. So he was quite right in saying I should find out for myself.

And so we raced along till we got to the dairy on the Petone Esplanade, where we stopped for a well-earned icecream cone. Another little detour onto the Petone Wharf – which is 400 meters long – to make up the final kilometer on our counters, making up the day’s cycling total to 27 kms.

First Rides

 

12 March 2013

My first ride on my lovely brand-new Giant Expressway 2 folding bike was a little baby-steps one in Seatoun, a quiet suburb, with wide flat streets. After John adjusted the seat and the handlebar so I wouldn’t have to lean on my hands too much, I tootled off in his wake. Just as well there was no traffic, as I think I was just a mite wobbly to begin with and not exactly travelling in a straight line.

It is true that if you learned to ride a bike as a child, you never forget how. Isn’t it fascinating that your body just remembers all the moves, even after more than 50 years (I found that with skiing too after 30 years – what a thrill that was!).

Along with the bike, I had bought some cycling gloves which were well padded under the thumb joint and heel of the hand, and they helped a lot in taking some of the pressure off my hands. I also found that if I didn’t grip the handlebar, but instead leaned on the outer padded heel of my hands, with my thumbs on the top, rather than around the bar, the pressure on my thumbs was not quite so bad.

Of course you have to grip the handlebar when you want to use the brakes. This was something I had to re-learn: slowing down before crossing an intersection, without wobbling or having to step off, and letting go of one hand to indicate that I was turning. More wobbles!

We rode around many of the empty streets, and then along the coast road towards Worser Bay and back. We did about 6km in half an hour. That might not sound impressive, but it was enough for me, for a first time. I reckoned I had deserved the coffee we had at the Seatoun Café afterwards (http://seatouncafe.co.nz/). They serve nice strong flat whites and lovely muffins. Bliss!

15 March 2013

My first big ride. Hutt Valley River Trail – 1st section – Seaview to Avalon.

The Hutt River Trail is a flat walking and cycling track that runs from Hikoikoi Reserve in Petone, along the East bank of the Hutt River to Upper Hutt. As State Highway 2 runs on the other side of the river, there are a number of bridges that the track dips under. These bridges also provide convenient places to break the journey.

We decided that today we would ride for an hour, and see how far we would get, then turn around and return the way we had come. It was a warm sunny day with a light northerly wind, so we would have a head wind on the way out, and a tailwind coming back.

We parked the car at Seaview, across the bridge from Petone. The track skirts the Hutt River and is flat, apart from a few little dips and rises where the track goes under bridges. It is very pretty with open views on the river in places, and in other places there are trees providing shelter from the down-valley wind.

I have more or less got the hang of the gears – crank the number down if you want less resistance, as in going up a slope or against the wind, crank the number up when you want more resistance, as in going down a hill or with a tail wind. John tried to explain it by comparing it with the gears in a car, but I told him not to try to blind me with science, it would only confuse me more. (Oh, I get it now – to go up a steep hill in a car, you need to change down to a lower gear! My “aha” moment!),

The combination of taking Voltaren before biking, using padded gloves, a smooth surface to ride on (no gravel), and having the seat and handlebars at the right height so that I don’t have to lean on them, all meant that I had minimal discomfort in my hands.

We rode as far as Avalon. I didn’t want to overdo things on a first outing, and we still had to ride back. It was nice having a tail wind on the way back.

In all we did 18kms, in about two hours. John said I “did very well”. Yes, I think I did. I was quite pleased with myself. But I was tired. After this I reckoned I was entitled to a nice lunch, so we went to Days Bay and had a very nice lunch at the Chocolate Dayz Café.

20 March 2013

Hutt Valley River Trail – 2nd section – Avalon to Silverstream

Today we rode the next bit of the Hutt River bike trail. We parked the car at Avalon and rode to some distance beyond the Silverstream bridges, just over 10km. Then we turned around, so we did a total of 21km, which took us about two hours.

We started out on the track on top of the stopbank, which was quite smooth to begin with, but after a while the surface deteriorated – it consisted of concrete slabs, but in quite bad repair, with cracks and filled-in potholes. It smoothed out near Naenae. When we got to somewhere near Stokes Valley, the track became a very narrow footpath beside the road with cars whizzing past. I didn’t feel confident that I wouldn’t keel off the edge of the footpath, so I walked it. We could have gone on another track which skirted the river, but that was on gravel so I didn’t want to do that. But then after a while the track we were on petered out and we would have had to ride on the road, so I chose the lesser of two evils and John lifted our bikes over the fence, so that we could join the gravel track. It actually wasn’t as bad as I had feared, reasonably smooth in fact, most of the way, anyway.

On our way back we stayed on the gravel track, which also avoided the bumpy stopbank track, which was good. There was just one bit that I really didn’t like, below the bit of road we had walked on the way up. The track became quite narrow and winding, with bush on the left and a drop on the right. I thought it was rather scary, so I chickened out and walked for a bit. The rest of the gravel track was OK. The last few kilometres, though, I was getting quite a sore tailbone, and my thighs were certainly feeling it.

Te Ara Harakeke – Plimmerton to Paremata Bridge

This track goes from the Paremata Bridge, along the Taupo swamp, near the motorway, up to Pukerua. Only we got it wrong. We thought it would also go along the Pauatahanui Inlet, but it didn’t, so we rode the “wrong” bit of it.

We parked by the Plimmerton railway station, and set off on the Ara Harakeke Cycle Track, in the direction of Paremata.

The track, part of it smooth, part of it gravel, took us along the water, then through the Ngatitoa Domain and past the Marina. We went under the Paremata Bridge, but then the track petered out. We tried going along the main road (on the footpath) and to where there is a walking track, but it was not rideable, so we turned back. We explored a bit beyond the Domain, but then went back to the car. In all we did only 6.3 kms, about 40 minutes. But that was OK.

While we were having a coffee at the local café, another couple arrived, also on fold-up bikes. We got talking, and spent a pleasant half hour exchanging experiences, and John helped them to sort out a problem with the chain on one of their bikes. They were retired like us, and this was only their second ride out on their new bikes. They had started their ride from the Paremata bridge and had gone along Karehana Bay, as far as the Marae.

Having had a look at a map of the track, I think we should explore in that direction sometime, and also do the Airlie Rd track, which after a gentle rise, is a flat ride to Pukerua Bay.

Hutt Valley River Trail – 3rd section – Silverstream to Birchville

We left the car under the trees, in a little park by the two Silverstream bridges. It was a gorgeous autumn day, sunny and calm, and the views across the river were quite beautiful. The trees are very subtly changing colour, the leaves are starting to go yellow and a bit of brown. Lovely wide flat trail, but it was mostly on gravel, so well before we got back to the car, I was suffering from severe “coccyx-shudder” – a very sore tailbone. The hands were not too bad. I am mostly leaning on the heels of my hands, which seem to be able to take the pressure OK.

We rode about 11kms out, and got to a place beyond the Totara Park Bridge, near Maoribank, according to the map, where the track suddenly became steep and narrow. A bit scary, I thought. We stopped where the track overlooked a bend in the river to take photos. I didn’t like the look of the path ahead. We’d done 11kms, and my sore tail was telling me I’d had enough, especially as we still had to get back to the car. So we turned around and headed back.

Despite a rather sore butt, it was a very enjoyable ride. As I am more confident now, I am able to look at my surroundings more, and I stopped a few times to take photos.

We did 22 kms in just over two hours. The very nifty bike “computer” that John fixed onto each of our bikes can be zeroed before each ride, but it also has an odometer, which records the total distance you have done overall. So far my total is 72kms. It also has a clock, and it records the maximum speed you’ve done – 21.4 km/hr in my case. That sounds impressive, but actually the only bit that was as fast as that was when the track went down into a hollow, where I freewheeled at speed, only to have to work hard to get up the other side. In fact our average speed is about 10km per hour.

Te Ara Harakeke – Plimmerton to Pukerua and foreshore Plimmerton to Horoeka Marae.

Having done the lower part of this Ara Harakeke Track two weeks before, we decided we should do the upper part of it. We parked by the Plimmerton station again, went under the station underpass, and up onto the track. It was a nice smooth track, quite flat to begin with, past a sportsground, then on a bit of road through an industrial area, past the truck weigh station on the motorway north. Then the track went between the road and the Taupo swamp. All smooth and plain sailing, except for the headwind.

Until we got to Whenua Tapu. From there the track started to climb, gently in places, steeper in others. I found it hard going, especially with the strong headwind. I really did try to keep going, gritting my teeth and telling myself “I can do this, I can do this”, but eventually it was just too hard, on my legs, and heart, and I had to get off and walk a couple of times. John was very patient, and waited for me while I caught up. Finally, John had got to the top at Pukerua, and I was half-way up the slope to get there, but I just couldn’t do anymore, so I signaled to him to turn around and go back.

The way back was a joyful tootle downhill with a tailwind. "Wheeee!" John said “just be careful and don’t go over 30km/hr” (on my cute little odometer). I didn’t fancy going any faster than that anyway, but I did get to 28km/hr at one point.

By the time we got back to Plimmerton, we had only been going for an hour, and had done only 10kms, so we carried on along the foreshore to Karihana Bay and beyond. We went as far as we could, and turned around when we got to a sign saying “Horoeka Marae – private road. Only walkers allowed”.

Eastbourne to Pencarrow Lighthouse

It was blowing from the south today, but not very strongly, and John suggested we could try the Eastbourne to Pencarrow road. With a southerly we would have a headwind on the way out, and a tailwind back.

The track from Eastbourne to the Baring Head Lighthouse is a gravel road, but there is no access to cars. Walkers and cyclists are allowed. John had to lift the bikes over the gate, as the little access gap was too small to get the bikes through.

John had fitted my bike with a new padded gel saddle with a groove to avoid pressure on the tailbone. I think it made quite a difference. Though we were riding on gravel all the way, my tail didn’t start to protest until about the 13km mark, when we were on the way back.

It is a simply gorgeous coast, quite wild. The tide was in and the waves were breaking around the rocks off the stony beach. On the other side of the road, the steep, gorse-covered hills of the Orongorongos.

With the lovely weather, the beauty of the scenery and the relatively calm seas, it was hard to believe that this was the same wild coast where, on 8 April 1968, just four days short of 45 years ago, many of the survivors of the sinking ferry Wahine were blown to shore.

The road snakes in and out of little bays. Near the points, the southerly would hit us, then as you came round into the shelter of the hill, it was back to balmy calm.

There were a few sheep that came crashing out of the shrubbery, obviously having been disturbed by these intruders. They galloped down the road ahead of us and disappeared back into the gorse further down. We were overtaken by a gaggle of guys in red fluoro vests on mountain bikes and we saw them again later when they were half-way up a steep track towards the top lighthouse.

At Pencarrow there are two lighthouses - one on top of the hill and one between the road and the water. The wind was pretty strong near there. Today was actually quite a mild day, I wouldn’t like to be there on a stormy day. A bit further round we were in the shade of the hill, and there was a nasty smell – from a sewer outlet, I think – and at the base of the rocky hill, there were two caves. We didn’t check them out.

Around the next bay, there were a couple of lakes – Lake Kohangapiripiri and Lake Kohangatera. We got to the site of the first lake, except that with the very dry summer we’ve been having, there wasn’t much lake to be seen. There was a big sign giving information about Lake Kohangapiripiri Raised Beach Ridge. It is a area of sensitive ecology. On the very wide shingle beach were patches of very low-growing plants, of different types. This is what it says on a DOC (Dept of Conservation) website: “Freshwater lakes so close to the sea are uncommon, particularly in the relatively unmodified state of the Pencarrow Lakes. They were formed in drowned valleys that have been blocked off from the ocean by beach ridges still bearing the evidence of earthquake history in the region”. 

This is as far as we went. We didn’t go to the second lake, or to the Baring Head Lighthouse, which is another four or five kms further along. But we will do that another day – on a windless day.

This was a really enjoyable ride. In total we did 16.5 kms, and it took us just under two hours – because we kept stopping to take photographs.

Cycling holiday in Hawke’s Bay

Last week, John and I packed up our folding bikes into our little Nissan Micra and spent a delightful few days cycling along some of the Hawke's Bay cycle trails. We stayed in a cottage in Clive, with direct access to a cycle trail, through the gate at the bottom of the garden.

Hawke’s Bay has a fantastic network of cycle trails, about 180 kms in all. We rode about 110 of those. The trails are mostly along the top of flood stopbanks, on nice, flat, firm lime sand surfaces. They go through areas that you cannot see from the road. One of these is the beautiful East Clive Wetland, between the beach and the stopbanks running south from the Clive River.

On our first day, we cycled a return trip from Clive through Haumoana to the Clifton Cafe, at the end of the road, from where the tours to Cape Kidnappers leave. We were lucky it was Wednesday, as the café is closed on Monday and Tuesday, and I would have been quite miffed if I hadn’t been able to have a coffee and lunch before tackling the return trip. We rode 35 kms in total that day. Quite a feat, I thought, for someone who’s only been cycling again for a month. But ouch! My poor sore behind and thighs!

The landscape is wonderfully varied – wetlands with lots of black swans, pukekos, white herons, ducks and other birds; orchards, red apples on the trees and wooden crates stacked, ready for harvest; vineyards, that had already been harvested; copses of yellowing poplars, with the rich autumnal fragrance of fallen leaves; the river, and of course, the sea.

The second day, we cycled the Puketapu loop, along stopbanks on both sides of the Tutaekuri River, and going through patches of wooded areas. At Puketapu, our halfway point, we had a well-deserved stop at the Puketapu Pub. It’s supposed to have an award-winning restaurant, but their coffee, I’m afraid to say, was not up to scratch.

Just before we got to the pub, we had to cycle to the top of quite a steep rise, which very nearly killed me – well, that’s a bit of poetic license – but for a “flatlander” like me, it was a big deal. Also rather scary was having to go over a one-lane road bridge, without separate cycle lane. John’s advice: “Take up ALL of the road”, i.e. ride down the middle of it, which meant that cars would HAVE to slow down behind you, and not try to overtake you. All the same, I felt seriously rattled when an impatient driver roared up behind me. I was glad to get to the end of the bridge, and to be able to scuttle off the road.

The next day, our ride through Ahuriri was troubled by moderate head winds. Some of the riding surface was smooth concrete which was a relief, considering the soreness of our muscles and behinds from the previous days’ cycling. We had planned to ride around the estuary, but the cross wind was unpleasant and made it hard work. I was feeling really tired, and was not able to get up much speed, despite the smooth surface. We rode along the Westshore waterfront, a wide beach with fairly featureless scenery, compared to the lovely views we’d had on other days. We stopped at the Snapper Cafe for some lunch before returning the way we came, with the wind now behind us. I was glad that was “only” 20 kms, my legs simply couldn’t have done more.

On our last day we rode from Clive past the wetlands again and then turned inland along the Tukituki River, towards Havelock North. This is part of a much longer, more challenging loop. We only did the short, easy (i.e. flat) first quarter of it, stopped at the Tuki Kitchen for a delicious lunch, then turned around and rode back.

One (minor) irritation was the many gates we had to negotiate. I’d just be getting into a rhythm, when we’d have to stop, get off, go through the narrow gap next to the gate, and then I’d have to get back on (each time you get back into the saddle your tail hurts again, till it “beds in” to become background pain) and find the rhythm again.

As it was a Saturday, we encountered a lot more cyclists than we had on the weekdays. We were delighted to come across a nice refreshment spot at the Bivvy Vineyard Cafe. It was run by the owners of the vineyard, and consisted of a coffee caravan, set in a garden with tables, seats and shade sails. A number of other cyclists had pulled up there too, and we enjoyed chatting, comparing bikes, trails and padded pants!

It was a most enjoyable holiday. Quite an achievement too, for me. But four days of cycling, during which we rode 112 kms, took a bit of a toll on my energies and caused a few aches and pains, making me feel “like a hundred and fifty years old”. I am glad that I won’t have to cycle again for at least a few days.
