'One of the best"
'Indeed the way it manages to balance big-hit compliance while still giving good pop is mighty impressive. Along with its stout chassis, long wheelbase and burly build kit, the Rail is capable of monster trucking its way down some pretty gnarly descents [...] the Bosch Performance CX Line motor is another key component to the Trek Rail’s all-round performance. In our experience, this is the best full-powered motor out there.'

'Trek has really gone all out with this bike'
'My first thought about the Rail 9.9 is how it resembles a new school American muscle car, with a ton of carbon fibre and lots of digitally integrated sensors, and as always, more power than its predecessor [...] If there was ever a bike that was ready for anything, the new generation of the Trek Rail 9.9 would be it.'

Best in Class winner!
It was a close competition, but not much could match the Rail on every type of terrain. The Bosch system will get you up any trail and the geometry is as close to perfect as we have found for all-around riding.

'Our e-bike of the Year'
'Rail dominates the descents and flattens the climbs… it’s every bit as potent as the Slash, but with its own built-in uplift.'

'Sets the bar'
'Whether flowing or technical, it literally glides by the competition like it's on rails while also offering plenty of comfort for long days in the saddle.'

Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.
Bosch Performance Line CX motor
The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
Bosch LED Remote
The Bosch smart system LED remote lets you easily change assist modes, activate walk mode or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.
Bosch Smart System
The Bosch smart system gives you an eMTB that's more connected than ever. The LED remote connects with Bosch eBike Flow app so you can get ride stats, adjust settings and perform system updates. Plus, Bluetooth connectivity makes it easy to add a display if you want to make it easier to see your ride data.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
Shimano Deore
Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff and the fun. With smooth riding, improved chain stability and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.

This suspension calculator will help you optimise your suspension settings for your riding weight. Simply follow the steps to find your best set up.
Learn moreComplete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Bosch's biggest battery for your biggest rides. The PowerTube 750 delivers 20% more range and a long service life.
Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure – no more error codes from mis-aligned sensors.
Oversized 34.9mm dropper post
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
