Trek Powerfly 7 Womens Electric Mountain Bike 2020
The Powerfly 7 Womens Electric Mountain Bike from Trek pairs a quality aluminium frame and proven MTB components with a Bosch 250W motor and 625Wh battery for a machine that allows longer, faster rides.
The Bosch Performance CX electric motor has four varying modes, with assistance between 60% and 340% depending on the setting. These modes are controlled from the Purion remote on the handlebar and can be switched on the fly so that the right level of help is always available.
Frame size-specific components ensure the best level of performance, with the XS model using 80mm travel forks rather than 120mm for more consistent geometry and the XS and S sizes having 27.5” wheels rather than the 29” found on the M and L. A mixture of well-proven XT and SLX drivetrain parts ensure excellent gear changes and the powerful 4-piston Shimano MT520 hydraulic disc brakes are ready to keep everything in check when required. Finally, the internally routed TranzX JD-YSP18 dropper seatpost allows the saddle to be lowered instantly for steep, technical sections.

- RockShox 35 Gold RL fork with 120mm of travel (80mm XS)
