Agree -the black is better - even if you don't need to lose an extra 10m or so of wire! One thing I'm sure you'll notice with that bike, John is that it will have a much more responsive feel compared to most electric bikes, because of the shorter chainstays and wheelbase, which are elongated...

Iteresting, John - excellent slide show - what a beauty! I bet you might have taken it for just a tiny spin round the block, even with your sore hand...? I had wondered where they had put the controller but now everything is clear. Obviously it will have all the dirt and water going down...

I was a late developer - didn't start smoking until I was about 22. I decided several years ahead that I would give up on my 30th birthday, and did. I kept off totally for 2-3 years but now do have the occasional one, or several, on nights out, but only a handful of times a year, with no...

I found no problem from having a Tongxin motor in the front forks of my bike, Stuart. When my controller had failed I rode it a few times just as a normal bike and I could forget the motor was there. One of my rides was 25 miles+ including off-road and downhill on-road sections with high...

Chris, I'd felt the same way as Flecc and Stuart. I would expect that as a lifelong cyclist you have good cycling technique, have developed the right muscles and have the confidence to attempt a steep hill that would set you apart from the vast majority of the population, even people half...

I understand it refers to the maximum speed of the motor under a typical load Ditto on John and Flecc's points on specific comments and posters that you object to, Mark. Frank

Tongxin does make a 175 rpm motor, so if that's what the label says, it probably is that. For reference the speeds are: 160 175 190 210 230 260 Frank

A fundamental law of economics, I'm afraid, Keith! If someone sees you are being subsidised to buy something from them, they will want a piece of your good fortune, and if they think they can get away with it, they will try! It's the same with Halfords, and other bike shops. They are a bit...

I agree - it looks nice but I bet they don't sell many of them!

I know, John, you are asking about YESA packs but for what its worth I can second Jeremy's experience regarding the technology from my 10Ah Ping LiFePO4. I don't have figures but range is well over 20 miles on my Wisper, and hill climbing performance is better than the original battery on my...

Here you go Keith - you must have missed this one!

Keith, I am pretty sure the Wisper and Quando motors are the same - so there's your answer! Possibly the larger wheel has less drag..?

It's not bad, Keith. There's more drag than, say, a Tongxin but it is rideable without power. It just feels a little bit heavy and high-geared.

No, they cost about £12. Then there is postage - probably as much again. But if I got one and a) it was the motor or b) the new controller blew again after a week, I would be no better off - so I haven;t bothered!

Agreed in princple John, however a further complication is if you climb a steep hill using pedal power you will accelerate on the downstrokes and slow down in between times, so you are actually doing quite a bit of accelerating! Big picture though, a bit of weight can make a few seconds...

Interesting discussion! I think the Tongxin motor is different from other hub motors so far available, with its negligible resistance and weight enabling a new category of bike to be created - the normal bike + help on hills. I think the Tongxin also lends itself to another category - normal...

This comes up from time to time. Personally I prefer rear. Main reasons are: Better steering - feels more bike-like Avoids the hammering effect though the handlebars that a heavy front motor can have on rough roads. My old Powabyke felt like a pneumatic drill on some poor surfaces, and...

The shop was On Your Bike in Tooley Street, by/underneath London Bridge station. I gave them a bit of guidance about getting the wheel off and it was on my Wisper, which does have a detachable cable to enable the wheel to come right out. They fixed it well enough while I was at work and I...

...with a very nice level of stock too!
