Rail 9.9 is a long-travel electric mountain bike built for ultimate trail performance. The light OCLV Mountain Carbon frame features an awesome RockShox suspension set-up, the latest wireless electronic drivetrain tech and the best e-MTB drive system on the market. It'll shred right alongside the enduro crowd, but the best part is that you'll always beat them up the climbs and get in the most runs.
It's right for you if...
You’re looking for a long-travel carbon e-MTB and you want nothing but the best. Your bike better have a wireless electronic drive train, a high-end suspension set-up and a powerful Bosch system that’ll fly up grinders in a flash.
The tech you get
An OCLV Mountain Carbon frame that fully encases a 625 Wh battery, a super-responsive RockShox ZEB Ultimate fork with extra-burly 38 mm stanchions and loads of adjustability, a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a Bosch Performance Line CX 250 W motor that assists up to 25 km/h and a Kiox controller. A SRAM X01 Eagle AXS drive train with an extra-low 52-tooth climbing gear, downhill-rated 4-piston brakes for unflinching descents and new Bontrager Line Pro 30 carbon wheels with robust SE5 Team Issue tyres that come completely tubeless-ready, including sealant.
The final word
The Rail 9.9 is all about top-shelf tech. It has the latest wireless electronic drive train, RockShox's best enduro fork and Bosch's most powerful battery and full-colour controller.
Why you'll love it
The SRAM X01 Eagle AXS drive train is smart, smooth and completely wireless
The full-colour Bosch Kiox controller displays ride info, connects with your Bluetooth® enabled devices and has a built-in theft prevention feature
The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you’re pedalling, and has less drag when you’re not
RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
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
