If I bought this I might want a brake upgrade. Even though it probably provides only about 150W (I always assume ebike power ratings are inflated), the extra weight alone warrants disc brakes IMHO.

When I see obvious out of shape ebikers passing me uphill while barely moving their legs, I’m assuming that the power rating of their ebike is about right and the torque curve might be weird to stay legal.

I agree that rim brakes on an e-bike is extra bad.
