The only way you can fix that is to change the controller to a KT one, which costs about £80. Your bike has the controller integrated into the battery case, so you'd have to mount the KT controller in its own case or in a bag.One question that I had: the assist mode has 3 levels and a throttle. Even at the lowest level it is a lot more powerful than other e-bikes. Is there a way to reduce the power in assist mode?
