Trek Rail 5 SX Eagle Electric Mountain Bike 2021

With an enviable list of hard-hitting, trail-ready components and an electric pedal-assist motor, Trek’s Rail 5 SX Eagle Electric Mountain Bike offers great value for money. The Bosch Performance CX, 250W motor has four power modes: Eco (60%), Tour (140%), Turbo (340%) and the intelligent eMTB (140-340%), all operated from the handlebar-mounted Bosch Purion controller and the downtube battery can be removed for recharging thanks to RIB technology.

29” wheels help the bike carry speed over rough terrain, and the Schwalbe Nobby Nic EVO tyres are tubeless-ready to help reduce punctures and improve grip. The Alpha Platinum Aluminium frame offers 150mm of travel along with Mino Link variable geometry, ABP (Active Braking Pivot) and Control Freak internal cable routing. The RockShox 35 Gold RL fork has 160mm of plush travel for when the going gets really tough, whilst 4-piston Tektro hydraulic disc brakes provide tireless stopping power.

SRAM’s SX Eagle groupset takes care of shifting the chain across the very wide-range 12-speed 11-50t cassette. The final icing on the cake is the TranzX dropper seatpost that enables the saddle to be lowered on the fly on steep or technical sections for better control and confidence.
