Trek Powerfly 7 Electric Mountain Bike 2020
The 250W Bosch Performance CX motor on Trek’s Powerfly 7 Electric Mountain Bike has four different power modes, Turbo - 340%, Tour - 140%, Eco - 60% and eMTB which intelligently adds between 140-340% depending on the conditions, all of which are selected on the move from the convenient handlebar remote. The powerful 625Wh battery is integrated into the downtube, but can be removed quickly and without tools for easy charging away from the bike.
Shimano’s MT520 4-piston hydraulic disc brakes provide great all-weather stopping power, with good modulation to boot, whilst the ever-reliable combination of XT and SLX 12-speed drivetrain parts guarantees crisp, accurate shifts even when under load. The TranzX JD-YSP18 dropper seatpost adds the ability to lower the saddle quickly on the fly for steep, technical sections, to give more control and greater room to manoeuvre. The size small is supplied with 27.5” wheels and the larger sizes with 29” wheels to ensure consistency of ride feel and handling across the spectrum.
