About the Powerfly FS 4 Gen 3
The Powerfly FS 4 is a full-suspension electric mountain bike that's eager to hit the trail. It packs in plush suspension to soak up rough-terrain and a powerful Bosch drive system to boost your capacity to crush long climbs and mile after mile of singletrack. It's equipped with Bosch's latest LED remote and Purion display that pair with the eBike Flow app to give you activity tracking, navigation and Bluetooth connectivity.
The tech you get - A durable aluminium frame with an ultra-user-friendly Removable Integrated 625 Wh Battery, a powerful Bosch Performance CX (250 Wh, 85 Nm) motor that helps you sustain speeds of up to 20 mph (25 km/h in Europe) and a smart system LED controller and Purion display. Plus, an SR Suntour 100 mm suspension fork, 100 mm of rear travel, a 9-speed Shimano CUES drivetrain, powerful hydraulic disc brakes and a dropper post.
Key Features
- The Powerfly FS Gen 3 features Bosch’s smart system with an LED remote that connects to the Bosch eBike Flow app for over-the-air system updates, customised motor tuning and more
- For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist smart system to its full potential
- Trek's Removable Integrated Battery (RIB) system looks great and is really 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 it's out of the way on descents
- It comes equipped with Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
