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.

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.

An Alpha Platinum Aluminium frame with a Bosch Performance Line CX motor (85 Nm, 250W), 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 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.
- The Powerfly FS+ gives you the powerful boost you crave on high alpine climbs, confident comfort on descents and a big battery for getting far out there
- Bosch's Performance Line CX motor delivers plenty of torque for steep, punchy climbs and is easy to control with the Purion 200 remote - plus you can customise it in the eBike Flow app
- Its RIB 2.0 removable integrated battery is easy to remove for travel and storage, and its virtually rattle-free while you ride
- Want even more boost? With the Bosch e-Bike Flow app, you can increase torque to 100 Nm and peak power up to 750W.
- It's compatible with Bosch PowerMore booster batteries, and you can even upgrade the 600 Wh battery for a bigger 800 Wh option to get way out there. Both parts can be retrofitted by the dealer

New RIB 2.0
