Built for US Class 1 e-bikes, the drive unit peaks at 600 watts, giving riders more help pulling away from stops or tackling hills without pushing the line toward mountain-bike territory. The redesigned gearbox makes the unit [smaller and lighter](https://www.trendhunter.com/trends/mahle-xs-system), helping bike brands fit it into slimmer frames that read more like conventional bicycles. Quieter gearing, smoother sensor tuning and support for Bosch's '[eShift' automatic gear changing](https://www.trendhunter.com/trends/ride-options) keep the focus on pedaling instead of managing the motor. Trek's first North American use of the motor on the 'Marlin+' moves the redesign quickly into a mainstream bike.
