Built to perform

Since 1886 (you read that right) Bosch has been building technology based around two driving principles — precision and quality. Today, they make some of the most revered motors in the e-bike world. They deliver powerful, natural-feeling assist that’s backed with a global network of support that’s there for you no matter what.

Intelligent assist

The Performance Line CX motor gives you 85Nm of torque to get you up steep climbs and accelerate to top speeds. Choose from 4 ride modes depending on the level of support you want. The Tour+ and eMTB modes automatically adjust the assist based on your pedaling input and the terrain so you get predictable, natural-feeling power.

Our Removable Integrated Battery (RIB) system lets you pull your battery off quickly and easily. No awkward reaching under your downtube or digging in the toolbox required.

Rail might get a lot of praise for being powerful, but you can put a big motor on just about anything these days. What really makes Rail rip is its progressive geometry, long travel suspension, and fine-tuned features that come together to make one hell of a mountain bike.

Long travel legend

With 150mm of rear and 160mm of front suspension, Rail is built to soak up big hits. Go ahead, point it down steep, chunky granite slabs. It’ll show you what it’s made of.

Tuned in with you

Quickly and easily adjust the fit and feel of your Rail with Mino Link, so your bike is always dialed to the terrain and your riding style.

Travel that won’t throw in the towel

Trek’s exclusive Active Braking Pivot keeps your suspension active while you’re braking, boosting traction and control even when the trail gets hairy.

Rips like a monster truck

Big 29˝ wagon wheels reduce rolling resistance so you can charge straight through the chunder on loose and wily trails.

Carbon Rail takes the trail up a notch with a light but burly OCLV Mountain Carbon frame and longer, slacker geometry that crushes through the gnarly stuff. Inspired by Slash, carbon Rail is built to elevate stability and speed on descents so you can cut loose and push it to the limits.

Intuitive integration

Bosch’s System Controller sits flush on Rail 9.8 and 9.9’s top tube for a clean look at your charge level and currently-selected assist mode.. Easily toggle through modes, or turn on walk assist with the compact new Mini Remote.

More power, more fun

All carbon Rail models feature longer new geometry that makes room for a lofty 750Wh battery. Head out for sun-up to sun-down adventures. We’ll wait.

Built for the hard knocks

An oversized head tube and seat tube give you the durability you need for big trail days, and offers room for bigger, more durable dropper posts.

Perfect pressure

Keep pressure under control with TyreWiz and AirWiz pressure monitors that track your tire and suspension pressure. Set desired pressures in SRAM’s AXS app and check the lights before each ride — red means you need to dial in the pressure, green means you’re ready to let it rip. Available on Rail 9.9 models.

On e-MTB race days Rail CXR is your ticket to the top step. Built with Bosch’s new limited-edition Performance Line CXR motor, this race-ready e-MTB accelerates faster off the line than any other Rail, so you can get you in front of the pack and stay there. Pair that with sustained power that keeps you moving up and over technical climbs, and you’ve got the recipe for gold in your pocket.

Power up your ride with a more pocket-friendly hard-hitter on Rail alloy. It loads you up with the same capable 150mm/160mm of travel as its carbon counterpart, but with an Alpha Platinum Aluminum frame that rips up the trail and not your wallet. Plus, you still get the new Bosch smart system with all the connectivity you want, so you don’t have to miss out on a customized ride.

LED visibility

Easy to access with your hands on the bars, this new remote features color-coded ride modes for instant recognition. It also auto-adjusts the brightness of the remote’s display depending on ambient light levels so you can always see your support level.

Sleek setup

Rail alloy skips bulky displays for a clean cockpit that’s fuss-free and tidy. Smart system capability means you can easily add a display later if you want more details on the go.

Built to elevate your e-bike experience, Bosch’s eBike Flow app lets you take control of your ride. It works with both iOS and Android phones, auto-updates your remote and display with the latest features, and the home screen gives you a quick overview of your most important ride data like battery status and range.

Customize your assist

Fine-tune assist modes to your liking. Get the most support on your climbs or stretch out the miles on longer rides with more efficient power use.

Set your record

Tracking starts as soon as your foot hits the pedal and pauses automatically when you take a break. Plus, your data synchronizes with integrated apps like Apple Health in real-time.

Tech built for Trek

Trek-exclusive integration means the eBike Flow app automatically recognizes your Trek e-MTB, provides service recommendations, and will even help you find your local Trek shop.

Gen 2 Rail gets you the same rugged, high-power machine as the latest generation, but skips Bosch’s smart system, Mini Remote, and LED display for a simple, app-free ride. It still features Active Braking Pivot, RIB, and 85Nm of torque, so you get plenty of bike for the buck with a legacy e-system.

Rail with smart system

Gen 3 alloy and Gen 3/4 carbon Rail give you Bosch’s smart system with a streamlined LED System Controller display and compact Mini-Remote. It’s everything you love about the previous generation — just a little bit smarter.
