The Giant engines were first introduced in 2017 with the release of the SyncDrive. The SyncDrive (70 Nm) is basically a Yamaha engine but with a completely redesigned software by Giant. The original software was optimised to deliver thrust with the first turn of the crank without any delay (Zero Cadence Support). Later on, the SyncDrive Pro engine was released to satisfy the requirement for the most demanding e-MTB riders. The SyncDrive Pro was based on the powerful Yamaha PW-X motor (80 Nm & 360% support). For e-bike designed for trekking & touring Giant developed a more dynamic engine SyncDrive Sport with 80 Nm of torque. The SyncDrive Life (60Nm) is the less powerful Giant engine.
All tuning devices are compatible with the latest Giant SyncDrive Life, Sport, Core, and Pro engines including the latest 2021 engines. The SpeedBox is a popular basic option. However, the VOLspeed is the most advanced tuning on today market since it offer several optimization options such as smoothing the engine behaviour and setting up the maximum speed for battery consumption optimisation. The badassBox is a contactless tuning box that simply slide over the speed sensor and it is installed / removed in just few clicks. The TunedBike is a software tuning which override the original software and do not require any hardware device to operate (to be release mid 2021?)
