Key considerations
- Requires a 48V battery with a BMS rated for the controller's peak (30A or more)
- Confirm your rear dropout spacing is 135 mm and that you can fit a torque arm
- Direct-drive weight (around 13–15 lb wheel) changes bike handling
- Freewheel, tire and tube are not included on most listings
