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 150mm of rear travel that fully encases a 500Wh battery, an e-MTB optimized 160mm RockShox 35 Gold RL fork, a powerful new Bosch Performance Line CX 250W motor that assists up to 20 mph, and a Purion controller. Plus, a 1x12 drivetrain 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 Bontrager wheels with nimble yet grippy 2.6" tires.
The final word
Rail 5 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. The powerful Bosch drive systems and durable part spec make for long-lasting fun.
favorite_borderWhy 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 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 exclusive frame tech as Remedy and Slash, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents
- 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

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
