Powerfly+ FS 4 Gen 4 is a full-suspension electric mountain bike built for getting out there—way out there. It pairs a tough aluminum frame with 130mm front and 120mm rear RockShox suspension to smooth out the rough stuff, while a Bosch motor and powerful 800Wh battery give you the boost to explore farther and climb longer.

TechnologyRefund policy

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.
