Trek Rail 5 SX 2020

Product Description

The Rail shreds! You won’t be able to resist throwing it into the downhills just as hard and fast as its non-electric brethren. The real difference comes on the way back up. Thanks to the game changing new Bosch motor you will be surging up the mountain just as enthusiastically as you came down. The key to Treks success in making the Rail feel so natural and capable is their use of fully E-MTB optimised geometry and suspension, based on their all-star Trek Remedy. This means that all 160mm of the RockShox suspension functions just as it should, even with the additional weight of battery and motor. All you need to think about is the trail.

The Rail features the new, Bosch Performance Line motor, which is smaller, lighter and more efficient than the previous versions. Most importantly for us, it feels more natural while you’re pedalling and has less drag when you’re not receiving any assistance. Ultimately making this one of the lightest, most natural feeling full-suspension e-bikes we have ever ridden.

The Bosch E-bike system delivers intuitive assistance as you pedal. You can customise this level of assistance via the handlebar mounted Purion controller, which displays ride info, connects with your Bluetooth-enabled devices and allows you to monitor your battery level on the go. The battery itself makes use of Trek’s Removable Integrated Battery (RIB) system, which makes it streamlined, discrete and super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage. The battery also features an external charging port for easy charging on or off the bike.
