The dynamic Bosch Performance Line (Smart System) drive ensures optimum assistance while the 10-speed SHIMANO derailleur gears means riders can even pedal up steep climbs with ease; firm disc brakes offer greater safety when riding downhill. Stylishly integrated into the slender down tube, the optionally 500 or 625 watt hour battery provides plenty of energy. Should more staying power be required, the model can be easily retrofitted with a larger 750 Wh battery. Even the smallest Wave frame has room for the large battery, which can be easily removed and inserted from the side. Specially developed for e-bikes, the SCHWALBE tyres roll with ease on roads, yet also have a firm grip on unpaved terrain. The MonkeyLoad system pannier rack allows panniers to be attached quickly and easily – everything just clicks into place. KETTLER's own K-Link coupling for trailers assures maximum suitability for everyday use.
