Colnago eGRV GRX Electric Disc Adventure Bike 2020
The eGRV GRX Electric Disc Adventure Bike from Colnago utilises Ebikemotion’s 250W hub-based motor to provide assistance up to a maximum speed of 25kph. By putting the motor in the rear hub and not the frame, there are no drivetrain losses and the frame remains free from any unsightly bulges. Shimano’s GRX groupset is gravel-specific, with great chain retention for use on rough ground and ratios suitable for off-road use. The WTB tyres are fast enough rolling for use on tarmac, but have enough grip for trail use too, giving endless possibilities when it comes to choosing the day’s route.

- Ebikemotion 250W hub motor and battery
