Exiting New Things

The controller has two two-wire connectors for e-brakes. They didn't provide the levers, but they did provide a plain full-width throttle.

I think they sell all the parts, so you can get whatever you want.

Would it be possible to use HWBS e-brakes (eg the one sold by BMSbattery) for that controller?

By the way, today I have contacted these guys, and they have told me they sell 48V "250W" kits.

Here you can see the different versions of the motor:

Surprisingly (at least for me), the only 135mm O.L.D. is the 5-7spd one, with no disc brakes. With disc brakes, width is more than 135mm. Even the singlespeed version is wider than 135mm!

So it seems this motor is ideal for an "old" bike, with road / v-brakes and freewheel-non-cassette derrailleur. Or a cyclocross one.

To complete the story in case someone picks up this thread, the noise has completely gone after re-greasing the gears, which was a fairly simple task. It's now quieter than say a Bafang SWX. I soldered the shunt in the controller about 25% of its length, which now gives 20 amps.

I've done about 200 miles with it over some very steep hills. I think it's brilliant. I'll now convert a better quality bike to use as my main bike with this motor.

I tried it with 44v at 15 amps, which made it a lot faster, whilst still keeping its climbing ability.

The only hassle with this motor is its width. You need to stretch your frame a bit to get it in. You need about 155mm for a disc brake. I did that fairly easily on my cheapo steel-framed bike, but my aluminium Rocky Mountain took a bit more persuasion. I had to stretch it to 220mm before it took on a permanent set at 150mm.

Interesting report, thanks.
