Simply electrifying! We set the bar high: a shifting system for the eBike of the future. So that getting around is more fun – in the city or cross country. What we’ve achieved is a minor revolution. The SRAM DD3 Pulse shifts automatically and integrated. We developed this concept with cutting edge partners. Depending on the speed, the gear hub automatically selects one of three speeds: whether you are braking for a traffic light or about to go up a steep hill. In addition to the automatic, 3-speed gear system you can also make manual adjustments to the derailleur at all times. Another advantage: With just one chain ring and shifter, you can fully focus on the urban jungle or just enjoying the scenery.
