Trek Powerfly FS+ 4 800 Gen 4

Powerfly FS+ 4 Gen 4 is the full-suspension e-MTB designed for those who want to push beyond their limits, whether on local trails or during high-mountain adventures. The robust aluminum frame features a RockShox suspension with 130mm of travel at the front and 120mm at the rear , perfect for absorbing roots, rocks, and technical sections, ensuring control and comfort even on the most demanding descents.

The heart of the Powerfly FS+ 4 Gen 4 is the powerful Bosch system, paired with an 800Wh battery that offers extended range so you can explore longer, tackle challenging climbs, and rack up elevation gain without worries.

The RIB (Removable Integrated Battery) is integrated into the frame but can be removed in seconds, without tools, thanks to the practical handle: an ideal solution for convenient recharging , increasing security during transport, or removing it when the bike is parked.

If you’re looking for a versatile, reliable, trail-ready full-suspension e-MTB , the Powerfly FS+ 4 Gen 4 is the perfect companion to take your rides to a new level of fun and performance.
