Trek Rail 9.8 XT Gen 4

It's right for you if...

You’re looking for a long-travel carbon e-MTB with high-performance parts and a lot of battery power. You crave the responsiveness of carbon, the stability of a longer reach, the plush feel of high-end suspension, and want the very latest from Bosch.

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, a super responsive RockShox ZEB Select+ fork, and RockShox Super Deluxe Ultimate Thru Shaft shock with a Shimano XT 1x12 drivetrain. You get the latest from Bosch with smart system Performance Line CX, including the new Mini Remote and Bluetooth® System Controller display that's integrated into the top tube.

The final word

This bike features across-the-board upgrades that make it a serious ripper—especially the suspension package. It's built for hammering gnarly descents, then flying right back up again thanks to the powerful Bosch motor, 750Wh battery, and parts that can keep up with all that rowdy riding.

Why you'll love it

1. Carbon Rail Gen 4 has the same enduro-inspired geometry and huge battery as the previous generation, but now it has a pocket in the top tube that makes Gen 4 compatible with Bosch’s integrated System Controller and Mini Remote
2. The System Controller shows your currently-selected assist level and remaining battery level. Its neatly integrated into the top tube for maximum protection and a sleek look
3. Bosch's smart system gives you all the same power and responsiveness with a new discrete Mini Remote that's streamlined with just the controls you need at your fingertips to toggle through assist levels or change to walk mode
4. Intelligent eMTB and eMTB Lite modes automatically adjust the assist based on your input to give you just the right amount of power for your ride
5. 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 e-MTB-optimized forks for less flex and more precise steering
