I have a Propella 9S Pro eBike. It has a rear hub motor. I want to switch to a Bafang mid motor, from a previous bike, as it has more torque and better battery life.
The Propella has dropouts for a hub motor. The dropouts accept an axle that has flats on it. The axle diameter is 12 mm, and the flats are 10 mm.
I want to replace the hub wheel with a Proterra Tough i30 142 x 12 mm. It accepts a 12 mm round axle.
Question is, can I purchase a solid axle with the flat ends? Or can I get a solid axle and grind down the flats to fit the dropouts? I don't want to drill out the dropout slots,as that would make it impossible to revert to the hub motor.
Thanks in advance.
