Rail 9.5 is a high-value carbon electric mountain bike with long-travel suspension for crushing gnarly descents. The OCLV Mountain Carbon frame features the same high-end trail tech as our analogue trail bikes, plus a powerful Bosch drive system that propels you up climbs so you can spend more time shredding.
It's right for you if...
You’re looking for a long-travel e-MTB, and you want the muted ride feel of a full carbon frame. You prefer to spend your hard earned cash on a frame, then upgrade your parts in the future.
The tech you get
An OCLV Mountain Carbon 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 that assists up to 25 km/h and a Purion controller. Plus, a 1x12 SRAM SX 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 Bontrager wheels with nimble yet grippy 2.6" tyres.
The final word
Our best-value carbon Rail is a pretty sweet deal. You get a quality long-travel suspension set-up, a best-in-class Bosch drive system and an awesome OCLV Mountain Carbon frame.
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 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
