That's what I use with my Tongxin. Works fine sensorless, but never tried with the sensors attached. An added "feature" with mine is that it locks the speed after holding down the throttle for ~6 secs (crude cruise control). No guarantee that BMS Battery will ship exactly the same controller...

Lets see which breaks first, the motor or the forks. :lol: :P My next bike will be very similar to your Trek but I'll keep closer to the rated power for this fragile little hub. :wink: Cheers Spike

Hi Crusoe The lightest, quietest motor is probably the Tongxin roller geared motor. I've been using one for about 6mths for my commute. It's the same motor as used on the http://www.cytronex.com/ bikes. I bought mine direct as a kit though. Pros: Almost silent, very small, very light ~2.5Kg...

Try ecycles@163.com They have the 80mm Tongxin/Nano motor for about 80USD. Spike

Bump...

I was looking for a Tongxin motor supplier and came across this site http://www.h9.com.cn/proshow.asp?articleid=607. Anyone had any dealings with them? Good or bad? Cheers Spike

I've tried the Dynamat on my 9C. It helps but doesn't stop the noise. It would be great if a change of controller could eliminate the noise altogether. Spike

I tried to register my e-bike as a moped in WA a couple of years ago. I was told it wasn't possible under any circumstances. They weren't interested in the registration fee at all. I just hide the motor and batteries under panniers, but I would prefer to pay the registration fee if I could.

When I tried a Bafang on my road bike I found that the weight of the batteries was the problem not the hub. It was unstable and I felt every bump in the road. I switched to an old MTB very quickly. Unless you are looking at LiPo then it might be something else to consider before you commit too...

It might be quicker and easier to just buy this motor http://endless-sphere.com/forums/viewtopic.php?f=9&t=16229 ?

Yes. Either of those should work. 250W is a bit weak but for a kid kart that might be a good thing. I think the original Kollmorgen controller was 400W so the 350W controller would be a closer match. You probably know this, but the extra watts won't make it go any faster, just adds more torque...

OK. This is probably pushing the law a bit, but how about 2 * 200w motors with different windings & separate throttles/controllers. I'm sure this has been done before, but it would be difficult to prove you used both motors at the same time and the combination could improve reliability, speed...

You can get controllers that run from 24V-72V. However, if you are planning to run it at 24V you're best off buying a 24V controller just to be sure. The only reason I can think for you to go for 24V would be if you can't afford more batteries. The motor works OK at 36V but is best at 48V...

I've used Crystalyte and E-Crazyman controllers. The wiring is not guaranteed to be the same even if the brand is, but here's a start... http://endless-sphere.com/forums/viewtopic.php?f=2&t=173&p=1656&hilit=+uspd+external+controller#p1656 http://endless-sphere.com/forums/viewtopic.php?t=4696...
