The Powerfly FS+ 8 is a deluxe full-power, full suspension electric mountain bike ready for adventure. Its sturdy Alpha Platinum Aluminium frame partners with a Fox suspension fork and shock (120 mm rear, 130 mm front) to smooth out rough trails, while a 12-speed wireless SRAM GX Eagle AXS transmission keeps shifting ultra-smooth through even the roughest terrain. 4-piston SRAM DB 8 hydraulic disc brakes provide stop-on-a-dime control for loose, wet and steep trails.
It's right for you if...
You want to explore without limits and you want a powerful e-bike to take you everywhere. You're looking for full assist to flatten long, punchy climbs and just enough trail-smoothing suspension to deliver confident handling in the rough. You want upgrades where they matter, like the clean, wireless shifts of a SRAM AXS T-Type transmission.
The tech you get
An Alpha Platinum Aluminium frame with a Bosch Performance Line motor CX (85 Nm, 250 W), a huge 800 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. 130 mm front and 120 mm rear suspension from a FOX Rhythm 36 fork and a FOX Float Rhythm shock. Tubeless-ready wheels with puncture-resistant 2.4˝ tyres, a 12-speed wireless SRAM GX Eagle AXS T-Type transmission for clean shifts, a Bontrager Line dropper post and hydraulic disc brakes.
The final word
The Powerfly FS+ 8 is an electric mountain bike built for discovering what's beyond the next climb. It features just enough trail-smoothing suspension to boost comfort and confidence, and plenty of power to get you wherever you want to explore.
