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 500 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 25 km/h 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
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 hard-charging frame tech as Remedy, 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
New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It’s also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It’s a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.
Custom eMTB Lite mode
Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.
Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure – no more error codes from mis-aligned sensors.
Bosch Purion Display
Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.
