Giant SyncDrive Pro

Giant SyncDrive center 250 W electric motors are the result of the close cooperation of Giant with the leader in electric motors – Yamaha, guaranteeing their high quality and reliability.

Despite the compact size, they deliver a high torque of up to 80 Nm, which shows just as soon as you start your ride. Their immediate response is also important – the motor starts running as soon as you begin to pedal. This quick response will not only help you when accelerating, but also truly comes in handy in many steep climbs, when you rely on the e-bike to "pull" you up.

The SyncDrive motors produce proportional and linear support, and their operation is predictable, smooth and quiet, simply a natural boost to your own energy.
