    Rail 9.9 is our best long-travel electric mountain bike. You get an extra-beefy carbon frame, unbelievably smooth RockShox suspension, super-precise Shimano XTR drivetrain, and a powerful Bosch Performance Line CX motor with an extra-long range battery and the new smart system LED remote and Kiox display that pair with the eBike Flow app to give you activity tracking, navigation, and Bluetooth connectivity.

    Its 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 customization and want all the cool features of the Bosch smart system.

    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 750Wh battery, ultra-adjustable RockShox ZEB Ultimate fork, RockShox Super Deluxe Ultimate Thru Shaft shock, and ultra-responsive Shimano XTR 1×12 drivetrain. You get Boschs 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. RockShoxs best enduro fork, Boschs biggest battery, the super-refined shifting of XTR, an updated frame, TyreWiz and AirWiz pressure monitoring, plus Boschs latest tech with smart system.

    Why youll love it
    – Boschs 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
    – Treks 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
