What is the benefit of Chargers two-chain system?
A two-chain drive train provides the Charger bicycle increased torque from the electric assist for peppy acceleration and more effective hill climbing. By integrating the drive-train with Shimano’s Nexus seven speed gear system, the motor, as well as the pedals, may take advantage of the bicycle gear shifting. This design will not limit your choice of tires, slip in wet conditions, or generate excessive tire wear. Compared with hub motors and direct drive motors geared directly to the front or rear wheel shaft (not connected to the pedal gearing), the advantage is most pronounced while using assist in the lowest and the highest gears.
