Don't quite understand that (isn't pedelec a difficult concept to describe in words!), but with the Wisper (and Powacycle) what happens is you pedal and, after about a second, the power cuts in quite noticeably - but not at excessive levels. It doesn't start completely from zero speed, avoiding...

They do have a lot of models with different speeds and configurations. Presumably with a different controller the Powacycle motor could be given more Amps too? For all I know that might fry it but I can't otherwise see why it couldn't be done. The Austrian chap who sells kits on ebay once...

I realise I asked the question ambiguously! What I was getting at was what power do pedelec systems deliver, rather than what technical solution is used. Obviously the two are closely related so you do have to consider both sides - so thanks for those comments. Taking this into account, I...

That's true, but isn't that output driven by the controller not the motor? I've no idea what a Powacycle motor could do if someone was minded to fit a 36v controller and battery. I suspect it would be able to do a lot more. I really wouldn't be surprised if it was a Bafang as it is a...

ditto! I only went direct to Tongxin in the first place because Tony didn't return calls/emails.

I actually find it pretty similar in those respects to the one on the Powacycle. I've not found a label on that one - maybe it's because it is a Bafang as well?

Yes, I remember you saying that, and yes, it was after I'd bought mine!

Thanks Flecc. It makes sense, but as I didn't even actively know it was in the Highway Code, I can't take my taxi driver to task on that point! We do tend to have laws based on principals rather than rules, which in general I like, but sometimes a rule can be that bit clearer, and easier...

By this I mean 'How much power do different pedelec systems deliver and how do the controllers decide when this power is delivered?' I am asking in the context of hub motor powered bikes with proper pedelec operation (power when you pedal without using throttle) - rather than: -...

I agree with that - from a cycling viewpoint, I see Tongxin hub motor as the next best thing to no hub motor at all!

I couldn't even finish watching it! I had to switch off when they showed the hole in the path section. I feel ill from the thought!

I would agree with that absolutely for every other hub motor I have used - certainly including the Suzhou Bafang on my Wisper. But I do think the Tongxin is in a different class! I've not ridden an Agattu but I feel my diamond frame bike with a Tongxin is at least as pleasant to ride unpowered...

I think my problem is controller but it could be motor - I can't tell for sure. As there's no alternative sensorless controller that I can get for my type of motor, wherever the current problem lies, I am exposed to controller faults. Since I got my kit there have been more problems with not...

Thanks everyone for putting my problems in context. I feel I've been lucky to escape with my moderate bad luck! There's clearly worse out there. I was doing a bit of research last night and discovered that in Spain it is illegal for a motor vehicle to come within 1.5 metres when passing a...

I had a very bad day today. It started just a few minutes from home with a bendy bus forcing me into the kerb and off my bike. I was in one of those daft dotted line cycle strips of green tarmac along the side of the road. He just moved across into my space, ironically enough because...

Flecc, How right you were! Please feel free to say that you told us so! I did loads of research before getting mine and came across some problems, but thought it would be ok for what I wanted. I couldn't find anything on those issues in the US (and didn't have the inside info from David...

Bad luck John! I've done nothing with mine yet, and given your news, in addition to all the other bad feedback, i think I will write off the Tongxin. As you say it is a shame as when it works it really is the business - but its just not reliable enough! Frank

Apart from the fact it is more efficient and that I prefer it, there are two practical reasons I have for prefering a diamond frame. I find it a lot more convenient when I have frequent stops, eg at traffic lights, as you can balance the bike easily against your leg and don't need to keep...

I've bought one of Mr Ping's 10Ah batteries. I decided that I only wanted it as an auxiliary for the Wisper, not as a battery in its own right, so 10Ah is more than enough. When I get it in parallel with the 13Ah Wisper one, I think the range will be adequate, even as both batteries start to...

Yes, that looks familiar! 7 gears was one of the changes when they moved from E to SE. Unfortunately they used the wrong megarange - its the 14-34, which is just a bit under-geared at the top end. I think they are going to put the 13-34 on the '2008' version of the SE. I have an 11-34 in...
