An upgraded OCLV Mountain Carbon frame with longer reach and oversized head tube and seat tube for maximum strength. An extra-long-range 750Wh battery, ultra-adjustable RockShox ZEB Ultimate fork, RockShox Super Deluxe Ultimate Thru Shaft shock, and SRAM XX1 AXS drivetrain. You get Bosch’s new smart system Performance Line CX with a new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app, plus TyreWiz and AirWiz pressure monitoring.

The final word

Rail 9.9 is all about top-shelf tech. RockShox’s best enduro fork, Bosch’s biggest battery, the smooth shifting of XX1 AXS, an updated frame, TyreWiz and AirWiz pressure monitoring, plus Bosch’s latest tech with smart system.

Why you’ll love it

Bosch’s new smart system gives you all the same power and responsiveness with a new Bluetooth-connected LED remote and eBike Flow app that puts even more control and customization at your fingertips

TyreWiz and AirWiz let you confirm your tires, fork, and shock are at the right pressure at a glance. No more getting the pump or gauge out just to check

RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control

The new frame is extra stout with a 34.9mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly eMTB-optimized forks for less flex and more precise steering

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

Bosch smart system
The new Bosch smart system gives you an eMTB that’s more connected than ever. The new LED remote connects with the new Bosch eBike Flow app via Bluetooth. You get tons of useful features at your fingers, and over-the-air system upgrades.

Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalized experience. Use it to customize your motor’s assist behavior, track your ride stats, and integrate your data with apps like Strava and Apple Health. There’s even handy features like navigation and service reminders.

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.

RockShox AirWiz and Quarq TireWiz
TyreWiz monitors your tire pressure while AirWiz monitors your fork and shock pressure. Set your desired pressure in the SRAM AXS app and then just check the lights before each ride—red means you need a pump, green means go ride.

RockShox Super Deluxe with Thru Shaft
With the all-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most refined shock on the market, with an updated air spring and an exclusive Thru Shaft damper that gives you tenacious grip, plush control, and the support you need for ripping rough descents all day.
