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...

Over the hills and far away - Drenthe has built a hill for cyclists

Steve, Peter and myself on "our" new hill: The "Col du VAM". It's the highest point in Drenthe at 4800 cm above sea level !
Each week, a small group of recumbent cyclists ride together from Assen on short touring rides. This morning three of us went on a 70 km round trip to ride up a new hill which Drenthe has created for cyclists of all kinds to ride over. "Our" new hill is now the highest spot in the province, reaching 48 metres above sea level. If you want to climb higher than this in Drenthe then you have to do it more than once.

Posing in front of the visitor centre before we properly begin our second descent.
This hill has been quite a long time in the making. While professional cycle races have also used the hill for many years (watch a video of Marianne Vos on the hill five years ago) it's been closed to everyday cyclists with a gate at the bottom because there was a potentially dangerous conflict on the only path which used to exist between pedestrians and cyclists descending quickly. That's why the general public were restricted to walking until yesterday when the new cycle-paths over the hill were officially opened.

Optional cobbles on the climb. There are a lot of
these around Drenthe for cycle-racers to use.
In total we now have 2.1 km of cycle-path on this hill which provide several routes up to the top and back down again. The climb has an average gradient of 10% and a maximum of 15% so it's a fairly good challenge. I've enjoyed riding over many larger hills in the past, but never before has there been a hill like this which was made especially for cycling over.

The quality is excellent: Wide and incredibly smooth asphalt paths are provided both for the ascents and the route back down again (where it's even more important).

It's really well thought out: A one-way system is used to prevent conflicts between those climbing and descending.

There is even a section of Kasseien (Kinderkopjes) to allow those who wish to to emulate their heroes in the Paris-Roubaix and other classic races, but because that's not everyone's cup of tea it's provided as an optional extra for those who want it while the rest of us can ride on asphalt.

Peter chasing someone else towards the steep part of the
descent. We saw many other cyclists on the hill today. I
expect it'll be even more popular on sunny Sundays.
My recumbent touring bike isn't really set up for hills. I've use a single front chainwheel with 60 teeth and the largest sprocket on the cassette at the back has 28 teeth so there's a minimum speed which it's possible to cycle at because going any slower will mean that I'll stop and never get started again and would have to push. As it worked out, all three of us reached the top, twice by different routes, without any problems in a reasonable amount of time.

The descent is marvellous, a unique experience in this area. It's deliberately been made less steep than the climb but 60 km/h is reached before you know it. This gives your brakes some work to do before the corners, but you always have the security of knowing that going off the asphalt doesn't mean crashing into anything hard because there's grass on both sides and you also have the certain knowledge that no car will ever get in the way of your safety as you descend because there are no cars allowed here.
While we were eating sandwiches at the top, this chap arrived over the cobbles with a handbike, having ridden from a village 10 km away to go over the hill. Cycling should be for everyone, including people with disabilities.

The visitor's hut at the top has an explanation of what lies beneath
It's Rubbish !
The VAM-berg is actually a pile of rubbish. Literally. It's a landfill site which has now been turned into a useful facility. It's not only useful to us cyclists, but these days, between 4000 and 5000 cubic metres of useful gas are extracted every hour from the waste. A fifth of the gas is burnt in a power station next to the hill while the rest of it is injected into the gas pipelines of the Netherlands and used by consumers at home to cook and heat their homes.

Recreational cycling and hills
Hills are not a problem for cyclists, they make cycling more enjoyable. If you go up a hill on one part of your journey, you get to ride back down again a little later on. No hill lasts more than a few kilometres. On the other hand, flat countryside means you can ride all day long against an endless and unbroken headwind, which costs you just as much energy as a hill without the reward of a descent.

Recreational cycling is often overlooked by cycling campaigners, but it is important as it provides more options for cycling. In my case it's one of the things which helps me to remain healthy. Recreational riders don't need much special infrastructure. They mainly use the same infrastructure as is used by local people to make everyday journeys. We just typically use more of it in a single day, benefiting from how everything is joined up across the Netherlands. Cycling infrastructure which doesn't allow people to make longer journeys also won't really allow them to make short journeys everywhere.

Our route to and from the VAM-berg included new sections of top quality cycle-path which are so new that I couldn't use them when I last cycled in this direction a few weeks ago. Other sections were part of a route which I've used for more than ten years to collect stock for our webshop from a supplier 40 km away.

Elsewhere, priority should first be given to providing infrastructure which allows specifically for everyday journeys, focusing on city centres and safe approaches to them, but a comprehensive cycling policy results in more than that. Journeys in any direction will be possible if a comprehensive go-everywhere grid of high quality infrastructure is built. In that context, a mere 2 km of cycle-path which exist for no reason other than to allow people to smile as ride up and down a hill especially built for them appears as part of a comprehensive policy. It should be seen everywhere, but actually it's only seen here.

This is an excellent and unique piece of infrastructure, in a province which prides itself on being the best place in the world for cycling.

As part of the official opening event, local school children rode up the hill and left pictures behind which are now on display in the visitor's centre.

Summer's here! Three days of cycling in Drenthe

At last winter seems to be over. The sun really came out this week and the temperature crept up to nearly 30 C. Touring through the countryside became so irresistible that I took two half days off and went out on Friday evening as well.

Through the forest with Steve on Wednesday afternoon's 90 km ride to the South of Assen.

Gloriously smooth cycle-paths run through many of the natural areas of Drenthe

A very old mushroom style directional signpost for cyclists. These provide a few more useful service to cyclists who are trying to actually go somewhere than the much hyped knooppuntennetwerk.

Cycle-path through heath

One of the many hunebedden (dolmans) in Drenthe.

Not all of our route was spent on cycle-paths through forest and heath. We also used some very small rural roads without motor traffic and cycle-paths like this which provide direct routes alongside major roads all across the province.

Everyone cycles in the Netherlands in one way or another. That includes older people riding electrically assisted bicycles and people with many kinds of disabilities, including poor hearing or deafness (which is what SH indicates)

We stopped for a break by one of several lakes on the route

This bench is a cycling facility. It was installed to give people a view of the lake.

A poem on the bench:
Cycling in Drenthe,
So simply, relaxed,
refreshing and surprisingly beautiful.

Everyone cycles in the Netherlands, including racing cyclists who use the same cycle-paths as everyone else. Why wouldn't you when these offer shorter distances to destinations, excellent surface quality and a very pleasant experience away from motor traffic ?

We're back in Assen, a city which sets many good examples for cycling infrastructure.

The width of cycle-paths like this one, connecting a suburb to the city, make cycling safe, attractive and convenient for all.

The next morning, heading North for an 80 km ride with Theo

Excellent quality concrete cycle-paths like this reach out in all directions from the city.

20 km further on we've swapped sides but still have the same excellent wide concrete path

Recreational paths (on routes which don't get used much for commuting or school traffic) can be narrower. This one just fits between the trees.

Let's not forget which country we're in. I'm happy to say that I'll be a Dutch citizen very soon now.

Recreational path selfie. Very smooth concrete.

Dogs like cycling too.



You might have heard that there are a lot of windmills in the Netherlands. Even by Dutch standards, this is a particularly nice example.

Super smooth wide recreational path shared with very occasional agricultural vehicles (we didn't see any).

This path is made unattractive to normal through motor traffic because there is a good surface only for cyclists. Tractors can of course be driven through the mud. This design removes motor traffic, unravelling routes in the countryside so that rural cycling is made more attractive and pleasant.

Just before the two paths merge again, into very wide smooth concrete.

Mum and baby

Our destination for today. Chips from De Belg (recently immortalised in a music video ;-)

Fresh potatoes fried in 100% vegetable oil (vegan). Excellent. Note that to the Dutch, fried potato chips (friets) are known to come from Belgium. People from other countries often think they originate elsewhere.

On the way back home, passing a school. As always, almost all students cycle to the school.

Friday evening's after work ride was just 20 km in length and there are just two photos. This shows a "hazard" on a recreational cycle-path next to the golf course in Assen - a golf cart. It's perfectly entitled to be here. Presumably a condition of the cycle-path being constructed through the golf course site.

To close, what could be more Dutch than tulips, bicycle and bicycle-path in the same photo ?
Of course I didn't start cycling on Wednesday or stop cycling on Friday night. Cycling is an everyday activity for us. Earlier in the week, and also on Wednesday, Thursday and Friday, I took parcels to the post office for our business. On Saturday I used my bike to go to the market for vegetables and today Judy and I went on a recreational ride this morning before gardening in the afternoon.

Drenthe was deservedly made the world's first UCI bike region a few years ago. We made our lives here because having looked around extensively this is the best place we found in the world for cycling.
