2021 Trek Rail 5 625Wh E-Bike


The Rail 5 is Trek’s best-value long-travel e-MTB. It’s equally as capable as a regular trail bike, it just gets you back to the top in a flash.

The Trek Rail 5 is an electric mountain bike built for ripping the big stuff. It features the same high-end trail tech as our regular trail bikes, plus the powerful new 4th Generation Bosch Performance CX drive system - it's like having your own shuttle. The powerful drive system and durable part spec make for long-lasting fun.

This e-bike is loaded with tech - a burly alloy frame with 150 mm of rear travel that fully encases a 625 Wh battery, an e-MTB optimised 160 mm RockShox 35 Gold RL fork, a powerful new Bosch Performance Line CX 250 W motor and a Purion controller. Plus, a 1x12 drive train with a wide gear range so you can always find the ideal cadence for the motor, a dropper post, powerful 4-piston brakes for more downhill confidence and 29er wheels with nimble yet grippy 2.6" tyres.
