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

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 Aluminum frame with a Bosch Performance Line motor (85Nm, 250W), a 600Wh PowerTube RIB 2.0 removable integrated battery, and Purion 200 controller. 130mm front and 120mm 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" tires, 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 setup smooths rough tracks and boosts confidence while you venture to alpine yurts or just around town.
Why you'll love it
- Powerfly FS+ gives you the powerful boost you crave on high alpine climbs, confident comfort on descents, and a big battery for getting way out there
- Bosch's Performance Line CX motor delivers plenty of torques for steep, punchy climbs, and is easy to control with the Purion 200 remote – plus you can customize it in the eBike Flow app
- Its RIB 2.0 removable integrated battery is easy to remove for travel and storage, and virtually rattle-free while you ride
- You can customize Powerfly for how and where you ride, with mounts for bags, lights, and racks
- Wanna ride even farther? Powerfly FS+ is compatible with Bosch PowerMore booster batteries, and you can even upgrade the 600Wh battery for a bigger 800Wh option to get way out there
