Rail 5 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 built to be just as capable of shredding 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 light and durable Alpha Platinum Aluminium frame that fully encases a 500 Wh battery for sleek looks and protection on the trail, a 160 mm RockShox 35 Gold RL fork, 150 mm of rear travel with a RockShox Deluxe RL shock, a powerful new Bosch Performance Line CX 250 W motor that assists up to 25 km/h and a Purion controller. A 1x12 SRAM SX Eagle drivetrain, dropper post, 4-piston brakes and Bontrager Line Comp 30 29er wheels.
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.
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
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
It's equipped with an external charging port for easy charging on or off the bike
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)
Features
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.
Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.
