Trek Rail 5 625w Gen 2
The Rail 5 625 is an electric mountain bike built for ripping the big stuff. It features the same high-end trail tech as our analogue trail bikes, plus a powerful new Bosch drive system that's basically like having your own shuttle.
It's right for you if...
You’re looking for an e-MTB that’s just as ready to shred as non-electric trail bikes. You want a powerful Bosch drive system that’ll propel you up climbs so you can hit lap after lap.
The tech you get
A burly alloy frame with 150 mm of rear travel that fully encases a long-range 625 Wh battery, an e-MTB optimised 160 mm RockShox 35 Gold RL fork, a powerful Bosch Performance Line CX (250 W, 85 Nm) motor that assists up to 20 mph (25 km/h in Europe) 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.
The final word
The Rail 5 625 is our best-value long-travel e-MTB. It's equally as capable as our regular long-travel trail bikes, it just gets you back to the top in a flash. Plus, the bigger battery means more time on the trail.
Why you'll love it
- Rail shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain – no shuttle or lift necessary
- The bigger battery means you can adventure for longer between charges
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
- Made with the same hard-charging frame tech as Remedy, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness and Active Braking Pivot (ABP)
- Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
