Uncompromisingly geared to e-bikes: the E-One Addix Race folding from Schwalbe
On e-racing bikes, the motor plays a more conservative role than on motorized MTBs or trekking bikes. Racing cyclists use the assistance of the lightweight, mostly removable drives selectively. For example, a rider might use it sparingly to keep pace with a strong group on climbs while still preserving battery life. While touring on flat terrain, many athletes leave the motor at home and ride their bikes like conventional racing bikes.
