Thank you for information. To be clear you have the motor on a Watt wagons frame? one of the wide tire versions of the UCP? I think our use cases for the bikes are very different. I am using it as a city commuting bike, a true pedal bicycle, just assisted. I do not use the throttle. I am always...

Yes, I understand. My goal would be to get it for the "improvements" and underpower it and hope that the design for more power and the quoted improvements make it more reliable. UART, which is a good point I guess I would probably need a new wire harness which would be quite annoying to do. I...

I'm looking for feedback on the new Bafang M630 motor. Specifically, I'm wondering if it would be a suitable fit for the WW Ultimate Commuter Pro frames and how well it performs in that application. I'm currently on my second and third M620 motor rebuilds, as they seem to require major work...

What are you asking for the frame/motor?

Tried pm'ing you.

What size frame?

My rohloff speedhub, has done well for me so far for about ~8000+ miles of high speed stop and go commuting (worn through 1 belt so far around 7500 mi). The oil maintenance is a bit annoying, the twist grip and the amount of force it requires even more so (I would love a paddle shifter, and...

The percentages for my 52v UC Pro have never been accurate, I was advised to have it display voltage. The battery fullness image has also always been wildly inaccurate, generally displaying 1/2 to 3/4 full until diving to empty suddenly at the last 2 volts of charge left on the battery...

Got my new rack installed, went with Tubus Logo Classic, steel to try and avoid the aluminium fatigue cracking the killed the original rack. I love having the lower rail to attach the panniers to and still be able to take them one and off with a top bag installed...

Had a funny bug come up with my new m620 motor controller. Not worried just thought it was funny, my new top speed is >4000 mph and I have really traveled an amazing distance. I have never actually seen odd numbers on the display, not sure what caused the weird numbers other than there must be...

Awesome, when I have time I definitely am going to try this, super useful, thank you!

Yeah, currently I don't think my PAS 9 is aggressive enough since the power cut is very very noticable. I am pretty sure its new configuration/feature, not sure how new, my original WW motor (2019) certainly did not cut noticeably until probably 45-46v.

This doe appear to be a known issue, or rather very very conservative settings from Bafang (GBK sent me this where people talk about it: https://www.facebook.com/groups/2323768714344360/permalink/6771801029541084), its apparently expected behavior. A way to deal with is apparently is to set draw...

I had ordered a whole new motor and display, UART as that is what my wiring is. I emailed GBK and they said there is nothing to be done, the droppoff is programmed into the controller to "protect" the motor. I would guess they mean the controller, I guess controller failures are maybe due to...

Good idea, worth a shot. I figured there would be zero support. I tried emailing.
