If you want an electric mountain bike that is just as ready to shred as conventional trail bikes, you will adore it. To complete lap after lap, you need a strong Bosch drive system to carry you up hills. This electronic bike offers a robust new Bosch Performance Line CX 250W motor that aids up to 20 mph, a 160mm RockShox 35 Gold RL fork built for e-MTBs, a 500Wh battery, a Purion controller, and a big aluminium frame with 150mm of rear travel. A dropper post, strong 4-piston brakes for increased downhill confidence, a 1×12 drivetrain with a broad gear range, and 29er Bontrager wheels with nimble yet sticky 2.6″ tyres are also included.


Bosch Performance Line CX motor

With up to 85Nm of torque and a sophisticated eMTB mode with Extended Boost that automatically varies the amount of assist according on the terrain, the Bosch Performance Line CX sets the bar for eMTB performance.

Custom eMTB Lite mode

Instead of a Tour mode, Trek eMTBs have a unique eMTB Lite mode. You get longer battery life and more natural-feeling power delivery.

Removable Integrated Battery & Range

RIB is a one-piece battery and cover with a built-in handle that can be withdrawn from the frame and put back in without any trouble or the need for tools. It’s the most practical way to take your battery out for transportation, safety, or simply for simpler charging.

Check out Bosch’s range calculator to determine how far you can travel on an electric mountain bike with one charge. You can make changes to achieve your most precise estimate even if we’ve pre-filled the data for this bike model and the typical rider. Calculate your range here.

Active Braking Pivot

Trek experts can fine-tune the suspension’s response to accelerating and braking forces separately thanks to Active Braking Pivot. This means that when you need it most, you have more assured control.

Alpha Platinum Aluminum Frame

Alpha Platinum Aluminum, a sturdy material used to construct the frame, will comfortably withstand the challenging terrain. The frame is designed to work with Trek’s Removable Integrated Battery (RIB), which is totally hidden inside the down tube, giving you space to add a bottle cage. Utilizing cutting-edge technology, the frame is built with a Mino Link adaptable geometry.
The top tube of the frame slants downward towards the seat post, which aids in lowering the standover height of the Rail. Less-than-average riders will enjoy how simple it is to mount the bike as a result. The ergonomic Bontrager XR Rail comp grips contribute to the ride’s increased comfort.

Shimano MT-520

Shimano MT-520 four-piston hydraulic disc brakes are used by Rail 5 and work well with 200mm rotors. These should let you to brake effectively in all weather conditions and offer you the assurance to tackle slick terrain and steep descents without worrying about slipping.

Bosch Generation 4 Motor and Purion Display

The Bosch Gen 4 featured in the new Rail represents a huge improvement over its forerunners. It features a wide peak powerband and an 85 nm torque output. The Bosch Gen 4 motor just keeps going where the Shimano and Brose motors stop. Due of the several pedalling possibilities, it appears to have substantial reserves.

And the early roadblocks of a massive display, a large battery, and a small chainring have all been overcome. The battery is a strong 630wh, and the chainring is now a standard size with 32 or 34 teeth. Furthermore, this display, which is a small, highly programmable kiosk, is installed in a special way on the top tube, beneath the stem.

Trek has been producing e-bikes for a while, but none have ever rallied as well as the Rail. Given that climbing would be aided nonetheless, an e-mtb should have a very capable descender with minimum sacrifices. With 150/160mm of travel and substantial 29er wheels and tyres, the Rail excels in this area. With a long 450mm reach for a medium bike and good angles of 75.5-degree seat and 64.5-degree head, the geometry appears to be perfect. Even a beginner mountain biker won’t lose too much bike space because the numbers are up to date enough for an experienced rider. Trek’s Mino Link technology also offers customizable geometry.

Oh! What a feeling

Reasons to love it

The Purion controller offers a Walk Assist feature and an innovative eMTB mode that adjusts power delivery automatically to the terrain.

Rail is just as brutal as its non-electric cousins, and it also propels you back up the mountain without the need for a shuttle or lift.

When descending, the dropper post enables you to quickly lower your saddle out of the way.

Made with the same exclusive frame technology as Remedy and Slash, including Active Braking Pivot, Straight Shot down tube for added stiffness, and Mino Link adjustable geometry (ABP)

The Trek Removable Integrated Battery (RIB) system is incredibly user-friendly and stylish. It protects the battery by completely encasing it in the frame, makes it simple to remove the battery without any tools, and allows you to mount a water bottle cage.

Our Rating​

Our best-value long-distance e-MTB is Rail 5. It’s just faster at getting you back to the top than our standard long-travel trail bikes. Long-lasting fun is made possible by the strong Bosch drive systems and robust part standards.

Your off-road adventures will take on a whole new meaning thanks to the incredible Trek Rail electric mountain bike. It combines the best specs and the newest Trek technology to create a performance that will stand the test of time.

This is one of the best e-mtb options on the market right now. It could be time to acquire yours with so many versions available that begin at an amazing $5,650 with best-in-class Shimano 12-speed builds. But act quickly because there aren’t many of these and they’ll probably be gone for the year before summer even arrives.
