Trek Powerfly FS 5 G2 Electric Mountain Bike 2020
Trek’s Powerfly FS 5 G2 Electric Mountain Bike pairs a 130mm travel chassis with Bosch’s 250W Performance CX motor to make a highly capable off-road machine. The Alpha Platinum Aluminium frame houses the RIB (Removable Integrated Battery), which can be taken off for easy recharging, and also features Trek’s Mino Link adjustable geometry for fine-tuning the ride characteristics.
The motor itself has four power modes, from Turbo to Eco, which add between 60% and 340% assistance to the rider’s input. Mode changes can be controlled on the fly from the handlebar remote, so the right option is only a click away, and there is even an intelligent walk mode to help when manoeuvering the bike.
Braking and shifting duties are performed admirably by Shimano’s reliable Deore groupset and MT200 hydraulic brakes, ensuring that fast gear changes are available even under pressure and that confidence-inspiring stopping power is always to hand. The TranzX dropper seatpost is a vital component for greater control on difficult sections and the 27.5” wheels also improve the bike’s nimble handling.
