Long term review: My Pashley PDQ touring recumbent. 20 years on the Ship of Theseus.

Long term review: 20 years ago I bought a Pashley PDQ recumbent bicycle for touring. I still have it and still use it.
Pashley PDQ recumbent bicycle. Compact, simple in design, reliable. Still a good buy second hand in my opinion.
Cycling need not be an expensive activity. Good quality bicycles last a long time. If we're careful to buy decent quality machines and we maintain them with some care then we can end up with the apparent luxury of a "fleet" of several bikes suitable for different purposes without that being expensive.

Recumbent cycling
I've been cycling for nearly 50 years, and for the last half of that time I've ridden recumbent bicycles for at least some of my journeys. My interest in recumbent bikes initially came about due to an injury: At the time I rode a narrow-tyred racing type bicycle with dropped handlebars and I worked as a software engineer so I had vibration in my hands on the way to and from work and then spent my working day was behind a computer with keyboard and mouse. Over several years this resulted in a carpal tunnel injury. I initially was interested in a recumbent as a way of relieving the pressure on my wrists while allowing me to continue to cycle. My first recumbent was a home made tricycle which was comfortable and fun to ride, but it was also heavy and slow. Nevertheless, it sufficed for my 16 km round trip to work and the new bike combined with a change in how I typed it resulted in more or less full recovery from my injury. But I now wanted to keep that comfort and also gain a bit of speed.

Next I bought a used Speed Ross bike. This was more like a racing bicycle to ride, being light and fast. Unfortunately it was also a bit fragile. It was fun, but not entirely trustworthy. For touring I really needed something else. The Pashley PDQ had several attractive features: two same-sized wheels (that means fewer spares to carry), a very comfortable seat, it was particularly compact, and it could take a lot of luggage. It was never the fastest of recumbents, but it also wasn't slow. It's certainly quicker than a conventional upright bike ridden in an position un-aerodynamic enough to give such a good view of where we're going.

Anyway, my PDQ was bought at some time in mid 1999 from D-Tek in the East of England, near where we lived at the time. Mine was an ex-demo machine so I got a small discount on the then new price. I paid something like 800 pounds for the bike, which works out as 40 pounds per year so far.

I actually don't know how many kilometres the bike has been ridden in total because it outlasted a few different cheap bike computers before I fitted a reliable bike computer. I unfortunately didn't keep a record of the distances I'd covered. The total now is probably not far off 100000 km. When we lived in the UK I used the PDQ as a daily commuting bike for several years. It was also used for holidays, weekly rides with friends, occasional Audax rides, and for touring rides such as Land's End to John O'Groats, to visit relatives (Judy's parents lived 100 miles away and if Judy had gone to visit in the week I'd ride up to meet them at the weekend).

We sold most of our bikes before emigrating so when we first came to the Netherlands but I kept this one and initially had just the PDQ and my town bike so the PDQ continued to be used for all the longer recreational rides as well as a 60 km per day commute, to collect stock and to visit people in other parts of the country. I work from home now and the bike has competition for the longer rides, so the PDQ's usage has dropped to just over 2000 km a year but for our first few years in the Netherlands it was doing a lot more than that.

The PDQ's origins go back a long way. It was originally an American design, the Counterpoint Presto, until that company went bust and the design was sold to the British company Pashley. Pashley produced it with some modifications until 2003. All PDQs are now second hand and all are a minimum of 16 years old, but unless they've been treated very harshly there is probably plenty of life in them yet.

Photos of the PDQ in action
The PDQ has accompanied me on many adventures and holidays as well as on many mundane commutes and other utilitarian rides.
My PDQ when it was nearly new on a short cycle-camping trip in Lincolnshire, UK in 2000 I used to wear a helmet back then. These days I wear a cycling cap in summer or something warmer in winter.

2006 - Old Warden aerodrome. That's a Pietenpol Air Camper in the background. What makes this an interesting aircraft is that it's one of several designs created using a car engine (in this case Ford Model A) which goes faster, and therefore achieves better efficiency, than the car which donated the engine. People often assume that flying is automatically less efficient than land bound transport but that isn't true. The problem with flying isn't that it's a particularly inefficient means of transport but, just as with driving, that it has grown in popularity so much that it now threatens our survival.

In the past the Fietsvierdaagse included 100 km routes so I've ridden some of those with the PDQ, but unfortunately they now only organise shorter distances. I've also ridden the PDQ on the 160 km Haren-Haren "classic" ride a couple of times.
Details of the bike
I apologise in advance for the dirt on the bike when I took these close-up photos. While I make sure that the bike is in good mechanical order, polishing it just takes time out from riding.

Due to the usage that this bike has had I've worn out many tyres, chains, cassettes and chainrings. The latter are made to last by replacing the chain whenever it has "stretched". This is made easier with a chain wear checking tool.

The frame, the seat, the handlebars and the luggage rack are all original, but I've rebuilt both the front and rear wheels (twice), the brakes, bell, gear shifter, cranks, chainwheel have all been replaced as they wore out or were broken.

There have been occasional incidents as well: A truck driving into me when I was on the way to work in Cambridge was the reason for one of the rear wheel rebuilds. caused me to have to rebuild the rear wheel.

The bike came with a Sachs 3x7 hub to provide a wider range of gearing but I found the hub gear part of this wasn't reliable. After rebuilding it three times with new bearings, the axle broke and so I replaced it with this standard Shimano hub which has been perfectly reliable. For the last eleven years I've had seven gears in total, which is enough for most purposes. I measure the chain length regularly and change the chain if it is worn as this saves the cost of also replacing the cassette and front chainring. I find that the SRAM PC850 chain is a good choice for a long life while not breaking the bank. There is some evidence of damaged paint to be seen. Some rust appeared on the rear triangle ten years ago and I resprayed the back end of the bike.

The handlebars: Original Tektro brake levers, which still work perfectly, reliable Sigma computer, the Busch und Muller mirror which I attached after two weeks of ownership still works perfectly - swapped from right to left after emigration. Replacement gear shifter and grips.

The original Tektro brakes were awful. They seemed impossible to adjust so that they worked reliably over any period of time. After a couple of years  I replaced them with a set of Shimano V-brakes which have been perfect. The brake blocks have of course been changed several times. Also the rims when they wore through due to braking.

The original seat rails broke after a few months. This was a production fault which Pashley were quick to set right: the faulty ones were replaced by a new design with a bit of triangulation under the rear support. 20 years later, the replacement seat rails are still fine. The seat looks worn but it's not broken and it's still a very comfortable bicycle to ride.

The bike was supplied with low quality tyres which punctured easily. I wore out a few more sets of tyres before settling on what I have now, the ever reliable and good performing Schwalbe Marathon tyres. I chose the relatively wide 47-406 size because these offer a nice smooth ride with a low rolling resistance while still fitting easily into the frame and forks. I use good quality dynamo lighting on the bike as it's always there ready for use when needed, never has a flat battery, and with this good quality headlight there is plenty of bright in a useful pattern.

When I bought the bike I wasn't at all convinced that this rubber suspension part would last. But it did. 20 years later it still works perfectly. Note that the bolt visible underneath was replaced. The originals worked loose and stripped the thread in the frame so I drilled them out, cut a thread and replaced them with a slightly larger size, installed with thread lock. Problem solved.

The idler, a skateboard wheel with grooves cut out on a lathe, was another part which I expected to fail early. However 20 years later it's still working perfectly. If it fails then I'll use a pair of standard idler wheels to replace it. The metal part around the idler can come loose and contact the chain. You can see where this has happened in the past. It's not a big issue - just tighten up the nut at the centre of the idler, taking care that washers are fitted sufficient to allow the wheel to rotate freely.

One of the most disappointing things about the PDQ as sold was the 46 tooth chainring on the front of the bike. In order to cycle at any speed it was necessary to use the step up hub gear which was less efficient. I quickly replaced the 46 tooth chainring with a 52, then a 53 and eventually settled on a larger than average 60 tooth chainring. This would be a very high gear to push if the bike had a 28" rear wheel, but with my setup it is about equivalent to a 46 tooth chainring on a bike with a larger rear wheel. Therefore I now have a sensible range of gearing without either a hub gear or a front derailleur.
Summary
It was a fine bike when I first bought it and it's still a fine bike now. Bicycles designed in a simple way, with no reliance on electrical parts or anything complex or unusual to go wrong, last a very long time. This is one of those bikes. Probably one of the best things I ever bought: it was an absolute bargain. 100000 km. 800 pounds. Just maybe I've spent twice that amount again on parts over 20 years. It still works out that this bicycle has cost me about 3 cents per km. I suspect that it costs more to walk even with cheap shoes...

Recumbent bicycles are excellent machines for touring. The PDQ has served me well, but there are also lots of other models out there which work extremely well. My wife rides a Sinner Spirit. Nazca, Optima and several other manufacturer's machines are also great. Pick one and give it a go. Second hand prices make it possible to try a bike with the likelihood that you'll lose very little if you don't like it and sell it on. A new bike also doesn't cost much if you ride it lots. Cycle touring need not be an expensive activity.

Relaxing ?
Every so often, someone asks me whether recumbent bikes actually really are comfortable. They're the same shape as what are sold as "relaxing chairs". So yes, recumbent bikes definitely are comfortable...

The Discovery Of Heaven

It was a lovely day yesterday and the cycle-paths of Drenthe were calling so I decided to make the journey to the Dwingelderveld to eat my lunch next to the somewhat famous radio telescope. Why there in particular ? I'm currently reading Harry Mulisch's "De Ontdekking van de Hemel" ("The Discovery of Heaven"). The author stayed in the area of the radio telescope during the time when he wrote the novel and the telescope features in the book as well as in the film adaption of "The Discovery of Heaven".

This was cycling for no reason other than it was pleasant to cycle so I looked at the map and roughly picked out a reasonably scenic 70 km round trip including the aforementioned planned stop for an extended lunch...

On the way out I stopped at a village bakery to buy some of their delicious, sourdough bread for my lunch.

Continuing onward, a reminder of the continuous progress being made. This country road isn't very busy, but it is used by some heavy vehicles and this cycle-path, which I followed for about 6 km before turning in a different direction, is a big improvement.

Cycle-paths which provide safe and direct routes make cycling accessible to everyone.

"For your and our safety, 60 km/h". A reminder that some places are yet to be improved.

The many cycle-paths through forests are a highlight of cycling in Drenthe

Sometimes cycle-paths through woods need bridges over areas of wet land.

The most beautiful cycle-path in the province, according to the local paper.

The destination

I made sandwiches with the bread I bought earlier and read a couple of chapters of the book.

A popular spot for hungry cyclists.

Europe's radio telescopes are linked to a centre near here, one of the many excellent things funded by the EU. The EU also contributed funds to build some of the cycle-paths along which I rode to arrive here.

On the way home, a reminder of what keeps us safe from the danger of large vehicles. It's not that Dutch drivers are especially skilled or careful, it's not that large vehicles don't exist here (for example, larger trucks are allowed here than in the UK), or that they're not allowed in to the same places as cyclists. We are safe because we rarely interact with those vehicles because both cycle-paths and the road junctions are designed to eliminate conflict and city centres exclude through traffic.

Also on the way home, the man in a fluorescent jacket is directing traffic in one direction at a time past the cherry picker. Cyclists were not hindered. Road works need not inconvenience cyclists
I returned home about three hours after I left, having had a good bit of exercise and a very tasty lunch. A very enjoyable extended lunch-break, re-discovering a little bit of heaven here on earth, using nothing more than my muscles and one of the most efficient means of transport to do so.

To the sea and back in January. A winter ride through Drenthe and Groningen + PPPPPP

We have installed triple glazing in some
of our windows. These ice crystals were
on the outside when I set off yesterday.
Yesterday was the date of the Noordelijke Velomobiel Tocht - a winter recreational ride starting in Groningen and heading to the coast and back.

The distance of the ride was supposed to be around 80 km, but it ended up a bit longer and when I added my ride from Assen to Groningen and back again my total distance for the day was 152 km. Some people came from somewhat further afield, one rider adding about 60 km on top of this.

We've had a mild winter until the last few days, but it was -9 C in our garden when I set off yesterday. The peak temperature in the afternoon was around freezing but it dropped again to -6 C by the time I had got home in the evening. Even with the weather protection offered by a velomobile the temperature does take something out of you if you're out in it all day.

A Dutch scene: Windmill, cycle-path, frozen canal, velomobiles. It's cold but there was no ice on the paths because there's not been any precipitation over the last few days.
One of several stops out in the countryside between the very pretty villages of rural Groningen.
Our lunch time destination - probably the most Northerly cafe on the mainland of the Netherlands
Most people had hot chocolate with apple cake. Significantly higher in calorific content than the vegan alternative of black coffee (more on that later).
Quick stop for a photo on the dyke
A "make your own postcard" view of the sea, with ice.
And then we began the return journey, first heading to the west along one of the roads nearest the sea.
Proper Planning Prevents Piss Poor Performance (the knock, the bonk, hitting the wall)
A fabulous day out, well organised, friendly and enjoyable. And yes, while what I'm about to write about might suggest to some readers that I didn't enjoy it, I can assure you that I most certainly did.

Unfortunately, it went a bit wrong for me at the end. All my own fault. The ride back from the organiser's home was in darkness, it was cold and I ran out of energy about 15 km from home. Most people who have ridden any distance will know how this feels. Having run out of available sugar to burn your body tries to keep going by burning fat, but because this is not so easily available you simply can't keep up the same effort. Trying to do so results in feeling quite awful. If you've ever felt like you wanted to vomit during extended exercise this is quite likely why. Depressing thoughts about perhaps never getting home at all can also follow.

There are two possible solutions:

  1. Stop and eat something
  2. Slow down.

Both options will cost time. Ultimately, slowing down will cost more time if there is a long way to go and the remainder of the ride won't be very enjoyable. For me that was the only viable option  because this came on when I was in the middle of nowhere and pretty much everywhere around here is closed on Sunday evenings so there was nowhere sensible to stop for food which didn't involve a detour. I didn't have far to go so I slowed down to the low 20s km/h and kept going. It's important not to let your body temperature drop and at least I could still work hard enough to keep myself warm.

Luckily I didn't have far to go and I wasn't alone. Three of us were riding towards Assen together. One of them needed to go somewhat further and he wisely kept his speed up and continued onward. Peter and I live very near to each other and he was kind enough to accompany me back to Assen at my speed. I was at no risk of getting lost as this was the last section of my old commuting route but it really helps a lot to keep your spirits up if someone rides with you.

A refreshment stop on an organised ride last summer. A top up of energy drink and food were available at regular intervals. It was also warm. This makes it much easier to cover distance.
It's been some years since I made this mistake and I should have know better. Knowing the symptoms is a good thing as at least you know what to expect and how to react, but I if I had planned ahead I wouldn't have had a problem. I should have had the right food and drink with me, but I did not. I took sandwiches, water, a couple of cartons of soya milk and some snacks. By the time I ran out of energy I didn't have anything left which was attractive and which I wanted to eat. I needed easily available sugar, not a packet of nuts. One more sandwich earlier on might have been enough to address the problem. I should have planned better for a lack of vegan food and drink at our stop in the countryside as that's standard and I should have been more self sufficient. A drink which contained sugar would have been better than plain water. Real sport drinks work well (not the horrible cough mixture flavoured stuff that teenagers like). That could have made a difference but I find it is difficult ever to drink enough when it's cold - because all drinks are cold in your mouth and while feelings of thirst come quickly in hot weather, I never feel thirsty in cold weather.

You live and learn. This was a great day out. I've taken part in this annual ride most years since we've lived here and I certainly intend to do so again. Next time, I'll prepare better instead of leaving it to the last minute !

Sunset in winter
Winter jobs
I've once again fitted Schwalbe Marathon Winter studded tyres to the front wheels of Judy's and my own city bikes. These are the bikes that we ride in any weather over short distances and while our local authority is mostly incredibly good at removing snow from the cycle-paths, there are sometimes little pockets in corners which can be dangerous and a few patches of old-fashioned tiled surfaces are a bit treacherous. For early morning cycling when you can't necessarily see ice, these tyres work as an insurance policy against falling. Schwalbe's Winter and Marathon Winter tyres are amongst our range of recommended products for winter cycling.

Meanwhile, elsewhere in the Netherlands, people are getting ready for the first ice-skating Marathon this year.
