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.
