Re: bbs02 - what size chainring for my commuter?

46t on 29" works fine for me in hilly Norway.11-34 casette and 107 kg rider.42t would be to high cadence for me

Re: YALU New BBS-Style mid drive kit with external controler

yes,it has a 95mm rotor and 1:23 gear ratio.So it should have some potential,especially as a 250w motor

Re: Bafang ultra,how strong is it.Does it overheat?

The Ultra has a significantly larger motor than the BBSHD so should be capable of more power. The gear reduction from the motor to the chain ring really isn't enough in my opinion but hard to change that. How does the torque compare to the BBSHD at same current? It has larger rotor,but BBSHD rotor ...

Bafang ultra,how strong is it.Does it overheat?

I already have a bafang bbs 36w 500w 25a and it needs to be significantly stronger than my Bafang bbs if it ...

This motor is much bigger than tsdz2
That's not obvious, judging by the picture

Re: New Torque sensing mid drive

what spseifictions? There is no specification about the torque or the controller.This motor is much bigger than tsdz2.Also you know nothing about the quality.And this motor is new,so spare parts maight be avaliable later

Re: New Torque sensing mid drive

The motor looks a lot bigger.So I guess much bigger stator rotor.And possible much more solid build.From what I read I get the impression the tsdz2 motor is not very high quality and not very torquey
