About the Trek Rail 5 SX Electric Mountain Bike 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.
