A small step forward

A small step forward

My idea of a Cargo Bike Club took a small step forward today, but first a wee bit of history:

Back in the autumn of 2010, Ulli and I were faced with the problem of getting a large pumpkin home from the allotment (not a problem that we have had since due to the poor summers). The solution I suggested then was to get a cargo bike, but at that time such bikes were very few and far between in Scotland, not that there are that many more now. This led me to come up with the idea of a Cargo Bike Club as a means of making cargo bikes available to the wider population (and a way of kick-starting the market for cargo bikes in Scotland).

When I first floated the idea of the Cargo Bike Club, it attracted a lot of positive comments. My initial idea was to use the City Car Club model, where the users would pay an annual fee to join the club and then have self service access to the bikes for a small hourly hire rate. There are, however, a few technical issues with security and self service access, which I have yet to overcome.

One person who thought he could over come these problems was Will Vaughan who took my idea (he did contact me and ask first) and started cargobikehire.com. However, he was planning on using a prototype technology from a small German startup called LOCK 8. I have seen the Kickstarter campaign raising funds to develop the locking system, but was sceptical about the level of security it would offer (the cable shown in the pictures is up to Solid Secure Gold level, as required by insurance companies). [Up date: I met Philipp Meyer-Scheling, the MD of Lock8 at EuroBike and am hoping to have another meeting with him in November] At the present time, it doesn’t appear he has managed to get the self service access up and running, but he does have a Bullitt available for hire in the Hereford area, so all credit to him.

The idea of the Cargo Bike Club has continued to gnaw away at me, and I have re-visited the idea a few times, but mostly I have gotten on with other projects like the Edinburgh Festival of Cycling. Where is all this rambling going, I hear you ask? Well, this year the Edinburgh Festival of Cycling Ltd has acquired an Urban Arrow cargo bike, and from today it is available to hire when not in use for company business.

Urban Arrow for hire

It is a small step, but it is a start, this is currently the only cargo bike available for hire in Edinburgh. Who knows, if this bike proves popular, there may yet be a Cargo Bike Club in Edinburgh. I am still working towards getting it off the ground one day.

Riding the flying bathtub

Riding the flying bathtub

In the run up to the second Edinburgh Festival of Cycling, I find myself having to move large numbers of festival programmes about the place. If I am just taking a few score of programmes to places where people might want to pick them up, that is easy to do with a courier bag or a set of panniers. However, today I was in the situation of needing to move several boxes (there are 150 programmes to a box and a box weighs 9.5 Kg) from Laid Back Bikes to EdFoC HQ, which is quite another matter. That is where the flying bathtub comes in.

Before going further, maybe I should explain that the “flying bathtub” is an affectionate nickname for the Urban Arrow family cargo bike (and one that I came up with this afternoon). Why, you might ask, “flying bathtub”? Well this particular Urban Arrow spent a couple of weeks sitting in the front window of the Cycle Service (where it was extracted from its cardboard box and built into a working machine), as a couple of frame bolts had gone missing in transit. While it was sitting in the shop, a number of customers asked about the “bathtub in the corner” and the name kind of stuck. The reason I call it the “flying bathtub” is because when you get used to the electric assist, it fair flies along (and this is a bike which weighs 42Kg unladen).

This wasn’t the first time I had ridden an Urban Arrow, I had had a wee test ride when the first one arrived in the UK last year…

… however today was the first time I had tried using it with a full load, in this case 66.5 Kg of programmes. So how did the bathtub and I get on? Well, starting off was a wee bit shaky, mainly because the front wheel is some distance ahead of the rider, which takes a little getting used to. There is also a slight play in the steering due to the nature of the ball joint at the end of the steering rod (see photo below), but within a few minutes I got the hang of it.

You can see the ball joint on the steering linkage to the left of the picture.

The other thing that takes a wee bit of getting used to is the transmission control which takes the place of gear leavers. Unlike most conventionally geared bikes, the Urban Arrow uses continuously variable NuVinci Hub gears. With this there are no set gears, instead there is a twist grip with an indicator window showing a cyclist on the flat. The straight line turns into a hill as you twist the grip. As it is continuously variable, there is no jump between gears as for conventional bikes, so at first you might not realise that you are changing gears, as it is so smooth. NuVinci are right when the say “It is unlike anything you have experienced before”.

Urban Arrow controls

When starting off with a heavy load, it is best to be in a low gear, with the indicator showing the wee cyclist climbing a hill. This makes it very easy to move away, even with the bike fully loaded. Once you are moving, you should then twist the grip to even out the hill on the indicator, until the wee cyclist is on the flat. At first I didn’t realise this and found that, once I had moved off, my legs where spinning round madly, with very little resistance and no increase in speed – as you might expect in a very low gear. I soon learned to twist the grip when I started to feel less resistance to my pedalling, and comfortably picked up speed. This, together with the Bosch electric motor providing assistance means that even with a heavy load you can actually fly along at a fair pace. It should be noted that the electric assistance cuts out at 15 mph (25 km/h) or if you stop pedalling, to comply with EU regulations. Although the route which I took was fairly flat with some slight uphill stretches on the way out (loaded), I found that I could get up to 20 mph (32 Km/h) and comfortably sustain a reasonable speed for keeping up with other traffic. Some drivers had a tendency to underestimate the speed at which I was travelling (but my experience is that also happens on an ordinary bike). This suggests that a VeloCityLight rear light would probably be a good idea.

The control for the electric assist (shown mounted to the left of the stem in the photo above) means that you can vary the level of assistance the motor gives you. This is done in three modes, Eco (the lowest level which makes the battery last longest), tour (which was the mode I was using) and sport. The display also shows the estimated range until the battery is exhausted and will need recharging. I don’t know how accurate this is, but I am told that you can expect to go about 25 miles (40 km) between charges.

Stopping wasn’t a problem either, as this Urban Arrow is equipped with Shimano hydraulic disc brakes (although the standard Continental configuration uses roller brakes), which provided plenty of stopping power even with a 66+ Kg load. The design of the Urban Arrow means that it can be stored out of doors with a cover over the cargo area (supplied as standard). There is built-in security in the form of a frame lock (something I am considering getting for my own bikes) and the electric assist can be disabled by simply removing the control unit. The only thing I found to be bit of a pain is the Dutch insistence on using Dunlop valves which makes pumping up the tyres very fiddly with a normal track pump. If I owned the bike, I would either change the inner tubes or fit adapter nipples (probably the latter).

Overall the bike was great fun to ride, as a car replacement it could be a useful addition for any family. It makes for very practical transport. In fact I enjoyed it so much, I will be taking it down to Round Six of The Pearl Izumi Tour Series (next Thursday) to see if Sir Chris would like to join me for a ride round the circuit. If he is lucky I might even let him ride in the bathtub at the front… 😉

Errata: Since I wrote this post the bike has had some work done and the steering issue has resolved.

Cargo bike culture?

Cargo bike culture?

Since I wrote a post suggesting the Cargo Bike Club, there has been a lot of interest in the idea from all over the world and even from London. However, one or two people have asked “what is a cargo bike?”, so I have found this wee video from Streetfilms, recorded at the Copenhagen cargo bike race, which should explain something of the concept.

My vision, or rather my (day)dream, is to establish a cargo bike culture here in the best wee country in the world, then spread it to the rest of the world! Indeed, the Australians have been reading my thoughts even before I have had them, and came up with the Watershed Bike Library. Don’t worry, I am not really intent on world domination…
