Based on the features of EX-1.0 Comp, Race has the following upgrades.

[Mid-drive motor system] EX-1.0 Race is a premium version of Comp. With a mid-drive motor, this crossway e-bike generates much more power than the others with a hub motor.

[10-speed Shimano derailluer] Race upgrades your derailleurs from a 9-speed Acera to a 10 speed Alivio rear derailleur.

[Hydraulic disc brakes] Instead of using mechanical disc brakes as Comp, hydraulic disc brakes is a lot more responsive and stable.
