The Powerfly FS+ 4 is a full-power full suspension electric mountain bike for taking on alpine adventures. Its Alpha Platinum Aluminium frame pairs with a RockShox Deluxe suspension package (120 mm rear, 130 mm 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.

- 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. Parts can be retrofitted by the dealer

Removable Integrated Battery

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It's the most convenient way to remove your battery for transport, security or just easier charging.

Bosch Performance Line CX motor

The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Bosch LED Remote

The Bosch smart system LED remote lets you easily change assist modes, activate walk mode or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.

Bosch Kiox 300 display

The Bosch Kiox 300 is tough, compact and easy to read with a full-colour display. Keep ride data right where you can see it including rider power, motor output, speed, remaining range and more.

Adventure-ready accessories

The Powerfly Equipped gives you maximum utility thanks to pre-installed accessories. You get a kickstand, front and rear lights, plus mudguards and a rear rack custom made for clean integration.

Bosch eBike Flow app

The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
