The Rail 5 is an e-mountain bike for rough things. It comes with the same high-end features as our non-electric trail bikes, but is pushed forward by the new, powerful Bosch drive system.
It's the right bike for you if…
… you are looking for an e-mountain bike that boasts the same off-road capability as non-electric trail bikes. You also want a powerful drive system from Bosch that will efficiently help you on climbs, or rather, get you under your feet.
You get this equipment
A robust aluminium frame with 150 mm rear travel, a fully integrated 500 Wh battery, a RockShox 35 Gold RL fork with 160 mm travel optimized for eMTBs, a powerful 250 W Bosch Performance Line CX motor with 85 Nm torque for pedal support up to 25 km/h and a Purion controller. You also get a 1×12 drive with a wide range of gear ratios for always optimal cadence, a variable seat post, powerful 4-piston disc brakes for more confidence on descents and 29" wheels with agile yet grippy 2.6" wide tires.
Our last word
The Rail 5 is our best value long-travel electric trail bike. Off-road, it is in no way inferior to its non-electric siblings, but thanks to pedal assistance it will help you back up the mountain in no time at all. The powerful Bosch drive system and durable parts guarantee long-lasting fun.
Why you will love it
- The Rail doesn't need to hide from its non-supported siblings. It literally pushes you up the climbs, eliminating the need for a shuttle or lift.
- The Purion controller has a Walk Assist function and an intelligent eMTB mode that automatically provides the required power depending on the terrain.
- It comes with the same proven frame technologies as the Remedy – such as the Mino Link adjustable geometry, the Straight Shot down tube for extra stiffness and Active Braking Pivot (ABP).
- Thanks to the Vario seat post, you can lower the saddle while riding so that it doesn't get in the way on descents.
- Trek's Removable Integrated Battery System (RIB) looks good and is user-friendly: The battery is fully integrated into the frame and is therefore well protected, but can be easily removed without tools and offers space for a drinking bottle holder.
New Bosch Performance Line CX
The new Bosch Performance Line CX motor is lighter, smaller and quieter than its predecessors and impresses with better integration and more agile handling. It's also more efficient, so you can go further on one charge. The intelligent eMTB mode automatically adjusts the level of support to changing terrain. After a one-off setting, this mode always delivers exactly the power you need so that you can fully concentrate on having fun driving.
Special eMTB Lite mode
Instead of a tour mode, Trek eMTBs have a special eMTB Lite mode. This mode offers more natural power delivery and longer battery life.
Removable Integrated Battery
RIB (Removable Integrated Battery) is a one-piece battery and cover combination with a built-in handle that can be easily removed from the frame and replaced without tools. Thanks to this feature, it is extremely convenient to remove the battery from the bike for transport, for securing or for easier charging.
Knock Block protects your frame when things don't go smoothly. The steering stop prevents your handlebars from being turned completely in the event of a fall, in order to avoid excessive pull on your cables and to prevent the handlebars from contacting the top tube.
What is the range?
The range assistant from Bosch shows you how far you can ride your eMTB on one charge. The data we preset for an average rider and for this bike model can be changed by you for a more accurate estimate of the range.
Landing gear calculator
This suspension calculator helps you to calculate the right suspension settings for your body weight. Just follow the steps to find the best setup for you.
Geometry adjustable via Mino Link
Adjust the steering angle (by 0.5°) and the bottom bracket height (by up to 10 mm) by simply turning a threaded nut. Turn the threaded nut and choose between a slack and an even slacker geometry without affecting the performance of the chassis. Exclusive to Trek.
Integrated speed sensor
The integrated speed sensor makes your life easier. The chainstay sensor is perfectly protected, while the special magnet integrated into the hub is optimally positioned – so error messages due to a misaligned sensor are a thing of the past.
Bosch Purion display
The Bosch Purion backlit display is a fully functional speedometer that also shows the service interval and battery life. Its thoughtful design allows the rider to scroll through the functions or select the desired support level without having to take their hands off the handlebars.
