The Powerfly FS+ 8 Gen 4 by Trek delivers superior performance and the latest e-bike tech in one sleek package. This full-power, full-suspension electric mountain bike ensures you are ready for any adventure. It equips a robust aluminium frame with ample travel to take the sting out of challenging trails, boasting 130mm front and 120mm rear suspension.
This beauty is all about unlimited exploration, which is why it brings together a potent Bosch Performance Line CX motor and a massive 800Wh Removable Integrated Battery 2.0 (RIB 2.0). Your ride never has to be cut short or compromised by a lack of power.
At its heart is the ambition to tackle treacherous terrains. Ascending steep climbs, coursing over punishing landscape or navigating adventurous trails? The Powerfly FS+ 8 Gen 4 has just the right amount of trail-softening suspension to ensure confident handling and supreme comfort.
The componentry consists of some high-performance features such as wireless SRAM GX Eagle AXS T-Type transmission for crisp shifts, Tubeless-ready wheels with tough 2.4” tyres, a Bontrager Line dropper post and hydraulic disc brakes. So, not only do you power up inclines with ease, but you also descend with superior control and flawless gear changes.
But there’s more to the Powerfly than just performance. With the eBike Flow app, you can personalize your ride experience to match your preference. Customise your motor's assist behavior, log your ride stats or even integrate your data with popular apps for a uniquely tailored ride.
Another standout feature is the RIB 2.0 removable integrated battery that’s a breeze to remove for travel or storage and promises near-silent operation while you ride. Plus, there’s the option to fit bags, lights, and racks, making the bike adaptable to your riding style.
What's more, you can extend your ride with Bosch PowerMore booster batteries, meaning your bike is ready from dawn to dusk.
In short, the Powerfly FS+ 8 Gen 4 is more than just an e-bike, it's your trusted companion for any cycling adventure.
