Bafang Mid-drive motor rotation.

[Dougs]

I have installed a Bafang Mid-drive kit on my wife's Catrike Trail. Everything seems to have went well except the motor rotates under power. Is there an installation solution I need to do? Some videos show installing a torque arm, which did not come with my kit. I do not see any Bafang Torque arm parts? Does anyone know the source for this part? Thank you.

Hi Dougs, you need to buy the BSB-1 Stabilizer bar from California ebike, secure it to the chainstay with either a hose clamp wrapped around a piece of old inner tube, or you can drill a hole and affix with a screw

Thanks Dewey. I'm not sure this stabilizer bar will work on the Catrike recumbent trike that I have converted. I will review the angle and spacer that would be needed to attach the arm to the trike's boom. The torque arm I saw was right angle fitting that rested inside the bottom bracket angle so the motor does not rotate.

Thomas, Thank you for your suggestions. I will check out the UTCustom arm.
