SPECS
It's right for you if...
You want to spare no expense on your e-MTB experience. You want the most adjustability, smoothest performance, longest range and most high-tech electric assist you can get. You love customisation and want all the cool features of the Bosch smart system, and you want wireless electronic shifting.
The tech you get
An upgraded OCLV Mountain Carbon frame with longer reach and oversized head tube and seat tube for maximum strength. An extra-long-range 750 Wh 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
The 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 customisation at your fingertips
TyreWiz and AirWiz let you confirm that your tyres, 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 34.9 mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly eMTB-optimised 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
