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 Performance CX motor. A 10-speed drivetrain, aluminium frame with a semi-integrated battery, pedal-assist up to 15.5 mph, and front and rear suspension help you take on more rugged trails with comfort and confidence.

|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|
|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|
|It's equipped with an external charging port for easy charging on or off the bike|
|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|
|The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain|
