Giant and Shimano teamed up to create a motor that’s seamlessly integrated with the Giant E-bike system. The EP8 motor is tuned to respond less to torque input from the rider and more to cadence. This makes it ideal for steady pedaling, an excellent option for gravel or road E-bikes. With a weight of only 2.8kg and 85Nm of torque, it is a relatively light and very powerful motor. We added slope and acceleration sensors to make it Smart Assist compatible, resulting in superior all-around performance. This system is designed to work with a Shimano Di2 drivetrain, allowing the rider to change power modes with the shift levers, so an additional E-bike head unit is not needed.

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.
