SRAM DD3 Pulse E-Bike Shifting System
NIJKERK, the Netherlands – SRAM recently launched the DD3 Pulse e-bike shifting system. This new shifting system is fully integrated.
Depending on speed, the gear hub automatically selects one of three gears: whether braking for a traffic light or going up a steep hill. In addition to the automatic wide ratio 3-speed gear system the rider can shift manually anytime. The automatic three-speed-shifting is fast and low-maintenance and well integrated with the electric motor.
