DESCRIPTION

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.

You’re looking for a seriously capable long-travel carbon e-MTB and you want nothing but the best. Your bike better have wireless electronic components, a high-end suspension set-up and a powerful Bosch system that’ll fly up grinders in a flash.

A light and durable OCLV Mountain Carbon main frame with carbon stays that fully encases a 625 Wh battery for sleek looks and protection on the trail, a 160 mm RockShox Lyrik Ultimate fork with Charger 2 RC2 damper, 150 mm of rear travel with a RockShox Deluxe RT3 shock with Trek's RE:aktiv with Thru Shaft damper, a powerful new Bosch Performance Line CX 250 W motor that assists up to 25 km/h and a Kiox controller. A 1x12 SRAM X01 Eagle AXS drivetrain, RockShox Reverb AXS dropper post, Shimano XT 4-piston brakes, a carbon handlebar and Bontrager Line Carbon 30 29er wheels with Bontrager SE5 Team Issue tyres.

Rail 9.9 is all about top performance tech. The latest wireless electronic components, RockShox's best enduro fork, Bosch's most powerful battery and full-colour controller. Plus, the light OCLV Mountain carbon frame is trimmed with lots of carbon parts, including the wheels and crank.

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
The full-colour Bosch Kiox controller displays ride info, connects with your Bluetooth® enabled devices and has a built-in theft prevention feature
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
The SRAM X01 Eagle AXS drive train is smart, smooth and completely wireless
