Hi,
I have a converted bike with a gospade motor. Between the BB and the chain ring/crank there's something about 1.5cm wide which I'm guessing is to the doo-hicky that actually turns the chain ring.
The problem is, in the lowest and second lowest gear the bike is noisy and it can be seen that in those gears the chain bends as it comes of the chain ring so that it can reach those cogs closest to the frame.
There's nothing that can be done about that is there? Looking at the bafang and tongsheng motors, it seems they all have that thingy attached to the chain ring.
