Trek Rail 7 Electric Mountain Bike 2021

All the capability of an analogue MTB with 250W of assistance available when needed - the Trek Rail 7 Electric Mountain Bike is a rip-roaring ride crafted from durable Alpha Platinum aluminium and built for trails. The Bosch Performance CX Motor kicks into play up to 25km/h and is compact, light and efficient to minimise drag when freewheeling and feel unobtrusive whilst pedalling. The Bosch PowerTube 625 battery sits within the frame when in use, maintaining a clean silhouette, and can be removed without the need for tools when a charge is needed. A full charge is complete in a little under five hours, but the battery can be used at less than full capacity should the need for a spontaneous ride emerge.

The responsive RockShox Yari RC fork provides a tasty 160mm of travel to tackle varied terrain, and there's 150mm of travel to the rear with the RockShox Deluxe Select+ shock - so it's safe to say this bike can handle higher drops. The Mino Link adjustable geometry can be tweaked to suit rider preference and the TranzX JD-YSP18 dropper seatpost is advantageous on sweeping bends and technical descents.

The 1x12-speed Shimano drivetrain makes for easier maintenance and consistent, reliable shifting with a generous gear range that keeps grinding at bay when gradients ramp up. Go full send on technical descents with confidence thanks to Shimano M6120 4-piston hydraulic disc brakes, which boast heavy-duty stopping power regardless of terrain or conditions.
