Giant SyncDrive (old model), 20MPH 36T e-bike motor

Powered by Yamaha, the SyncDrive is a compact and lightweight motor that is ideal for daily transportation or recreation. It has Smart Assist technology, featuring six sensors including slope detection and an accelerometer. These sensors allow the motor to produce power based on rider input and terrain. There is no need to select a certain assist mode, you can simply ride the same way you normally would but with more power. The result is an extremely comfortable, quiet and natural riding experience with powerful efficiency.
