Some pics....2 bikes were the older style Cadenza frame, the 3rd was a rarer upmarket Matrix model intended for offroad use, it had some extra frame reinforcement. The Cadenzas were fitted with Tongxin motors, small 'frog' type batteries and thumb throttles. The Matrix had a 250W Bafang with...

I placed an order with Greenbikekit for a couple of motors, controllers etc on the 21/09. One item was urgent so I paid the slightly higher fee for the Fedex express service (2-4 days) The response and updates from the company were very prompt, I received the tracking number for the Express...

Hi Pat, I've done several successful conversions of the older, single beam 26" wheel Dahons using Bafang or Tongxin motors. They were purchased as bare frames from C H White for around £75-100, the current type are more expensive at around £220. The older beam type frames are still available...

Thanks for all the replies. As Eddio mentioned, it may be the norm for many parts of China, but I rather like the idea of BMS doing some midnight wire snipping.......:cool: Alan

Thanks Tony, it vanished half way through placing an order:( Alan

I've been unable to connect to site for the past 24 hours, having tried with several different browsers, comps and connections. Anyone else able/unable to connect to it? Alan

A lot BMX bikes you see around don't have fittings for a front brake, just a rear. Quite different from the race BMX bikes we saw in the Olympics. If you have a few minutes to spare this video shows some interesting views and the fixie brakeless riding technique. Whatever you think of the...

Hi again, I use a similar system with Alfine hubs, and I've got both the Alfine fixed tensioner and a spring loaded one. The first is easy to set up, the spring loaded one needs to be set to quite a high level of tension to prevent chain sag. I'd guess you are ok with it as it is, but a pic...

There are several methods of calculating correct chain length, most are on this page:Park Tool Co. » ParkTool Blog » Chain Length Sizing The obvious starting point is if it will change onto the biggest cog(bottom gear):) Alan

From the company that makes small wheel tandems: Circe Cycles | Atlas It folds and might even go under a table next to the Brompton:rolleyes: Alan

The last of the CR18 36h stock will supposedly be with SJS later this month, I don't know how many, or exact date. Sun also make a CR 14 rim in the same size(349) with 36h. A colleague in America stocks them, but they're slightly narrower, don't appear to be stocked in Europe, and I've no idea...

If anyone wonders what a 36h hub in a 32h Brompton size rim looks like, it looks like this - not much different from a normal wheel:rolleyes: Alan

Hi Matt, Making 'mismatched' wheels can be done with different lacing patterns, depending on hub and rim size, but all require several different spoke lengths, patience and a clear head:) Using a 28h rim needs more of all those than a 32h! Alan

The obvious answer is to have a wheel built with the motor and correct size of rim, you'll have a better quality wheel and less problems for the extra cost. The only potential problem with this route depends on how many spokes the hub/wheel uses. The current main supplier of 36h Brompton size...

Hi Tony I'm not a fan either, having been involved in all sorts of drive systems in a different field. I was simply making the point that they're available, and have a dedicated but small following. I'm not so sure it's conservatism in the bike market that is the main problem, but this...

Come on folks, where have you been looking? There are quite a few hub geared, belt drive (usually Gates, but Phil Wood is also supplying parts) bikes already on the market:p Add a decent front wheel kit and you're away. Plenty of people have converted frames, or you can buy one already...
