Our new SyncDrive Pro 2 electric bike motors are co-developed with Yamaha and optimized for the Giant E-bikes they are paired with. The motors have a compact shape, and at just 2.7kg they are lighter than the previous generation. These premium motors also deliver increased torque output (85Nm) with reduced noise levels while retaining the instant engagement and narrow Q-factor that improve pedaling performance.

SyncDrive Pro 2 also blends into our frames perfectly and gives you an extra 37mm of extra bottom bracket clearance, without effecting Q-factor. It also comes with Giant’s Smart Assist automatic adaptive support mode, as well as intelligent walk assist.

Smart Assist

This automatic adaptive support mode system uses six sensors and advanced algorithms to determine the optimum power support needed on variable terrain. Smart Assist also maximizes efficiency by not using unnecessary energy. And since it always delivers just the right amount of pedaling support, it also improves rider efficiency.
