You also get an incredibly strong carbon frame, unbelievably smooth RockShox suspension, super-precise Shimano XTR drivetrain, and an incredibly powerful Bosch Performance Line CX motor.
You should do it if…
When it comes to your e-MTB experience, you want to cut no corners. You want the greatest electric support that you can get in terms of adjustability, performance smoothness, range, and technology. You enjoy customization and want the Bosch smart system’s interesting features.
Your tech
An updated OCLV Mountain Carbon frame for optimal strength, featuring a longer reach and larger head tube and seat tube. A 750 Wh battery with an extra-long range, RockShox ZEB Ultimate fork, RockShox Super Deluxe Ultimate Thru Shaft shock, and Shimano XTR 1×12 transmission with ultra-responsiveness. You receive the Bosch Performance Line CX smart system, which includes a new Bluetooth® LED remote for new connectivity, all-in-one navigation, and activity tracking via the eBike Flow app, as well as TyreWiz and AirWiz pressure monitoring.
The last word
High-end tech is the focus of The TREK Rail 9.9. RockShox’s top enduro fork, Bosch’s largest battery, XTR’s ultra-precise shifting, an upgraded frame, pressure monitoring from TyreWiz and AirWiz, as well as Bosch’s most recent tech with smart system.
Reasons to love it
With a new Bluetooth-connected LED remote and eBike Flow app that allows you, even more, control and customizability, Bosch’s new smart system give you the same power and responsiveness.
With the aid of TyreWiz and AirWiz, you can quickly determine whether the pressure in your tires, fork, and shock is appropriate. No need to remove the pump or gauge to check anything
Because RE:aktiv with Thru Shaft operates more quickly than a typical shock, it tracks the ground better and maintains control.
The new frame is significantly more durable, with a 34.9 mm seat tube to accept dropper posts that are more robust, and a bigger head tube that works with forks designed specifically for eMTBs to reduce flex and improve steering.
The Trek Removable Integrated Battery (RIB) system is super user-friendly and stylish. It protects the battery by completely encasing it in the frame, makes it simple to remove the battery without any tools, and allows you to mount a water bottle cage.
