As smooth as Bosch/Yamaha mid motors for a ridicolously low price
Gives you the feeling of an expensive Bosch bike, for almost no money! Incredible build quality, good display. Lots of clearance issues fitting to a full suspension bike, but I fixed it by cutting off lots of brackets and material on the motor :)
The whole clue of this motor is the torque sensor, which no other retrofit ebike systems have!
Power wise, it feels strong when pedaling, but the throttle leaves a lot to be desired (very slow response, and less power than when pedaling). Climbing torque feels a lot lower than BBSHD, even if they pull about the same amount of power (1450 watts), on the other hand this motor has a lot better sync between cadence and motor RPM/torque curve than BBSHD.
