Rail 5 is a full-suspension electric mountain bike built for ripping the big stuff. It features the same high-end trail tech as our analog trail bikes, plus a powerful Bosch drive system thats basically like having your own shuttle.
  • Rail shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain—no shuttle or lift necessary
  • The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
  • Made with the same exclusive frame tech as Remedy and Slash, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)
  • The dropper post lets you lower your saddle on the fly so its out of the way on descents
  • Treks Removable Integrated Battery (RIB) system looks great and is 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

Bosch Performance Line CX motor

Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Custom eMTB Lite mode

Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.

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.

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.

What is the range?

To see how far you can ride your electric mountain bike on a single charge, check out Bosch’s range calculator. We’ve auto-filled the variables for this bike model and the average rider, but you can make adjustments to get your most accurate estimate.

Compliant with leading safety regulations

The e-systems on Trek and Electra e-bikes are third-party tested to meet the latest e-bike safety regulations, including the stringent UL 2849 certification — so all you have to worry about is where your e-bike will take you next.
