Trek Rail 7 SLX XT Electric Mountain Bike 2020
The Rail 7 SLX XT Electric Mountain Bike from Trek is built for high speed fun on the most technical trails. The burly aluminium frame has 150mm of travel from the RockShox Deluxe RL rear shock paired with a 160mm RockShox Yari RC fork, ensuring that no drop, rock or jump is too big to tackle. Technology and design features such as Mino Link variable geometry, ABP (Active Braking Pivot) and Control Freak internal cable routing are all present and correct. Tried and tested Shimano XT and SLX drivetrain components along with 4-piston MT520 hydraulic disc brakes offer ultra-dependable shifting and braking in all conditions whilst the 29” Bontrager wheels and tyres carry speed well and provide great traction.
The Bosch Performance CX 250W pedal-assist motor has four modes available: Eco (60%), Tour (140%), Turbo (340%) and the intelligent eMTB (140-340%), which are easily switched between from the convenient handlebar-mounted Purion remote. With 625Wh of power, the battery is good for long rides, and is removable from the frame for off-bike recharging if necessary.
