For direct drive innerrunner, this one seems interesting too. Bigger diameter means good torque, Very short drive.
Going to be a pain to waterproof for direct drive when compared to the motors being discussed over on
3 Motors currently in test there - all direct drive and waterproof: ReacherTech, MayTeck & Flipsky
The real dimensions are OD: 84mm x L 63mm
The torque is missing in the spec but could be inferior to a 80100 motor.
490eur is not cheap… and the 280kV is probably too high.
