Powerfly FS+ 4 is a full-power full suspension electric mountain bike for taking on alpine adventures. Its Alpha Platinum Aluminum frame pairs with a RockShox Deluxe suspension package (120mm rear, 130mm front) to smooth out rough trails, while a 10-speed Shimano CUES drivetrain provides simple, low maintenance shifting. Tektro Gemini SL 4-piston hydraulic disc brakes give you stopping power at a great value.
