I have created a 2WD Xiaomi electric scooter, by removing the back passive wheel and replacing it with the front electric motor from another Xiaomi scooter.
Some hundred hours and mods later, I ended up with a fun to drive 2WD scooter without any mechanical brakes!
Thus, I have created this spacer which allowed me to add a 160mm disc brake to the scooter.
Beware, you need to drill the side of the motor wheel and fix it in place with screws and nuts.
"Should" fit any Xiaomi scooter motor, the one I used is 250W and came out of a M365.
Printed in ASA, with low speeds and high temperatures.
Have fun!
