Rather than pollute other threads with this I thought I'd put this out there. My other forum reading has come across this solution for the Yose Power Lishui controllers.

It needs no programming knowledge as the settings are adjusted by the C500 display. Might be a solution for people that are considering swapping out there system as it would only cost around £5 for the dongle needed to flash it and a bit of soldering. Of course I would imagine that there are very few users for it so it could go wrong necessitating a new controller, but if you were doing that anyway it might be worth a punt.


There would be no need to worry about adding a torque sensor so the 12V tap information would be redundant. It would just be soldering the 4 wires to the programming port and flashing the hex file.
I haven't tried this so anyone having a go would be a pioneer in the field.

"known issues:

no direction detection for PAS, use dual hall PAS"

If pedalling backwards results in zero effort hill climbing, this seems more feature than bug.

Resetting the pedals when stopped at a traffic light could be fun. Off you shoot.
I don't know the type of PAS on the Yose Power kits but a few of them look dual hall sensor.

Any test certs I came across for EN15194 compliance, shows that "Assistance shall be provided only when the cyclist pedals forward" seems to be a requirement for this euro standard as example below..
