DESCRIPTION 

Powerfly FS 4 is the gateway to more exciting trail adventures. It's a full-suspension electric mountain bike that pairs the capability of a 130 mm trail bike with the power of a Bosch motor. A 10-speed drivetrain and a strong aluminium frame with Trek's easy-to-use Removable Integrated Battery (RIB) help you take on more rugged trails with comfort and confidence.

It's right for you if...

You like singletrack trails and want an e-MTB with a more capable full suspension set-up so you can take on more rugged adventures and stay comfortable and efficient when you do.

The tech you get

A durable Alpha Aluminium frame that fully encases a long-life 500 Wh battery, a powerful Bosch Performance CX 250w drive system that helps you sustain speeds of up to 25 km/h and an ergonomic Purion controller. Plus, a SR Suntour XCR 34 130mm suspension fork with an adjustable air spring, a 130 mm RockShox Deluxe RL shock, a 10-speed Shimano drivetrain and hydraulic disc brakes.

The final word

Full suspension lets you take on bigger, more technical trails. It's more comfortable, more efficient and faster in rough terrain. You're getting great parts and a powerful Bosch e-MTB system, but the biggest advantage of Powerfly FS 4 is the suspension package built for better riding on rugged trail adventures.


favorite_borderWhy you'll love it

  1. 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
  2. Trek's 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
  3. It's equipped with an external charging port for easy charging on or off the bike
  4. It rides like a mountain bike because it is one: it has the same frame and suspension tech that we've refined in our decades-long trail heritage
  5. The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
