ELECTRIC MOUNTAIN BICYCLE, GENERATION 3 TREK RAIL 9.8 GX AXS
Long-travel carbon e-MTB Trek Rail 9.8 GX AXS Gen 3 rips like our heaviest trail rigs and propels you back up the mountain. Even the frame has been improved so that you may have the most fun possible on the steepest, most technical descents. Bosch’s cutting-edge technology includes the latest smart system, the Performance Line CX, which boasts a 750 Wh battery and new functions like activity monitoring, navigation, and Bluetooth connectivity.
If you meet the following criteria, then THIS IS WHAT YOU NEED…
You want a carbon-electric mountain bike (e-MTB) with wireless electronic shifting and a large battery for extended rides. You’re looking for the security that comes with a longer reach, the comfort that comes from top-tier suspension, and the cutting-edge technology of the new Bosch smart system in an e-bike.
THAT TECH YOU GET
A stronger, more durable version of the OCLV Mountain Carbon frame, featuring a longer reach and a bigger head tube and seat tube. RockShox ZEB Select+ fork and RockShox Super Deluxe Ultimate Thru Shaft rear shock, and a 750 Wh battery for extended riding time. You’ll have access to cutting-edge features like Bluetooth® LED remote for new connectivity and all-in-one navigation and activity monitoring with the eBike Flow app, as well as wireless electronic shifting from SRAM GX AXS and the newest from Bosch with the smart system Performance Line CX.
Last, but not least:
The AXS drivetrain, together with the rest of the modifications, makes this bike a strong contender. The powerful Bosch engine, 750 Wh battery, and durable components make it ideal for smashing down treacherous slopes and rocketing back up.
Why You’ll Enjoy It so Much
With the addition of a Bluetooth-connected LED remote and the eBike Flow app, Bosch’s new smart system provides you with even more control and customization options while maintaining the same level of power and responsiveness.
You can view your journey details on the full-color Kiox screen, sync your gadgets through Bluetooth®, and even prevent theft with this ingenious device’s integrated feature.
By responding more quickly than a standard shock, the RE:aktiv with Thru Shaft improves ground tracking and control.
There is less flex and more precise steering on the new frame thanks to the bigger head tube that combines with beefy eMTB-optimized forks and the 34.9 mm seat tube that can accept more durable dropper posts.
Trek’s Removable Integrated Battery (RIB) system is both aesthetically pleasing and incredibly convenient, as it completely conceals the battery within the frame for safety, allows the battery to be removed without the use of tools, and allows for the attachment of a water bottle cage.
