Re: tsdz2 torque sensor broken

Mine has also stopped detecting torque following a rebuild (it was making a grinding noise as if sand had got in it). During the disassembly I broke one of the wires going to the spring ring but I managed to resolder it successfully - I checked there was resistance between the two contacts. Anyone c...

Re: Mid-drive PAS tandem MTB mod

The thing about a BBSHD is it would have to go on the front BB, theres just too much going on at the rear for it to fit. This would mean the front BB cannot have a torque sensor (unless I got one that measured chain tension). This is the reason, along with value, I was leaning towards cyclone. EDIT:...

Mid-drive PAS tandem MTB mod

I'd like to add a motor to my tandem. At present I only want pedal assist, ideally this would be controlled by a torque sensor. We still want to ride with other non e-tandems sometimes, so it can't be too noisy. It would be nice if it looked stealthy too, but that's not so important. My initial plan...

Re: Ibis Mojo HD and Bafang BBS02 marriage

The photos of this build have disappeared. If you could reupload them that would be great. Let us know if you've made any further mods over the last couple of years too, as I'm about to modify a Mojo HD in the same way.

Re: Best geared hub motor for slow climbing

Thanks for the rim advice. I decided against a mid motor because being a tandem there is already double the power going through the drivetrain and I didn't want to overload it. Also, I wanted the conversion to non-powered to be quick & easy. There are performance benefits of being all-wheel drive of...

Re: Best geared hub motor for slow climbing

Its still a sport bike, both riders would be pedaling hard in a position optimized for generating power. I just want it to be roughly equivalent to a third person pedaling so they wouldn't have get off and push. I think I've decided to go for the 2-speed motor controlled by a torque sensing bb. The ...

Re: Best geared hub motor for slow climbing

Further research suggests the Xiongda 2-speed motor is the more suitable of these two.
But how does it compare at low speed to the Bafang RM G060.350.DC?
Bafang more torque over 10mph but less below?

Re: Best geared hub motor for slow climbing

I see what you mean. I think that's a bit more than I need actually - around 500w should be enough. I'd also like to keep additional weight to a minimum and would prefer hub diameter to be <6" if possible. 44mm flange spacing is a bit narrower than I'd like too. Hub width is not so important as I ha...

Best geared hub motor for slow climbing

Hi All, I'm after a front motor for a tandem mountain bike, for help climbing at 3-8mph. PAS only. Would need to pull away from a standing start on a 20% incline with a 200kg load with maybe 300W of pedal power. Front wheel will be a fat 26er. I'm considering the Xiongda YTW-06 and the Xiongda 2-spe...
