Are there any e-bike motors suitable for 200mm hub dropout width?

Post by Janjarmosz » Apr 13 2021 9:58am

Hello everyone,

I am really struggling with finding a motor that will suit my 200mm rear fork, is that possible to fill out the gap? Any way of making 150/175mm hub suitable (like the one on the picture)? I really want to avoid cutting and welding my frame

All the best to you guys!

You can make torque arms that bolt into the fork ends, but have the inside measurement you need. 25mm thickness per side gives you plenty of room to make them clamp the axle flats.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.
