The Powerfly FS+ 4 is a full-power full suspension electric mountain bike for taking on alpine adventures.

It features 130 mm of front and 120 mm of rear trail-smoothing travel and a powerful Bosch Performance Line CX motor with a PowerMore compatible Removable Integrated Battery 2.0 (RIB 2.0) for getting far, far out there.

It's right for you if...You're itching to explore and want a full-power, fully-capable e-MTB to take you there. You want the trail-smoothing benefits of a full-suspension mountain bike for rough roads and light singletrack, but don't see steep rock gardens or jump trails in your forecast.

The tech you get - An Alpha Platinum Aluminium frame with a Bosch Performance Line CX motor (85 Nm, 250 W), a 600 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. 130 mm front and 120 mm rear suspension from a RockShox Recon Silver RL fork with Solo Air spring and Motion Control damper and a RockShox Deluxe Select shock. Tubeless-ready wheels with puncture-resistant 2.4˝ tyres, a 10-speed Shimano CUES drivetrain for clean shifts, a Bontrager Line dropper post and hydraulic disc brakes.

The final word - Explore the beyond with Powerfly FS+ 4. This capable and powerful e-MTB is ready to keep you soaring up the trail with a grin as big as you have on the downs. Its capable full-suspension set-up smooths rough tracks and boosts confidence while you venture to alpine yurts or just around town.

Features:
  • 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
  • You can customise the Powerfly for how and where you ride, with mounts for bags, lights and racks
  • Want to ride even further? The Powerfly FS+ is compatible with Bosch PowerMore booster batteries, and you can even upgrade the 600 Wh battery for a bigger 800 Wh option to get far out there
