Powerfly FS 4 is a full suspension electric mountain bike built to tackle rugged trail adventures. The plush suspension setup soaks up rough terrain, and the powerful Bosch electric drive system boosts your capacity to crush climbs and mile after mile of singletrack.

• For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist system to its full potential
• 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 to remove the battery without tools, and lets you mount a water bottle cage—even on full suspension e-MTBs
• The dropper post lets you lower your saddle on the fly so its out of the way on descents
• The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
• Powerfly FS frames feature a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means youll get the fastest wheel that fits—29˝ wheels on larger frames, 27.5˝ wheels on smaller frames

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.

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.
