SRAM officially presented its new e-Bike powered drivetrain system at Taichung Bike Week.
Originally teased back in March, the system is a ground up new design that uses chain torque and frame flex sensors to gauge user input and automatically shift and adjust power. The motorized rear hub has a 2-speed internal gear system with a user adjustable shift point. The system is super clean, what you see here is what you get. The only wiring runs from the battery pack on the rear rack to the rear hub motor – no wires, controls or displays to clutter up the cockpit.
