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. Removable Integrated Battery RIB is a one-piece combination of battery and cover with a built-in handle that can be easily removed and reinserted into the frame without tools. Thanks to this feature, it is super convenient to take the battery out of the bike for transport, security, or easier charging. Bosch Performance Line CX Motor The Bosch Performance Line CX sets new standards with its power of up to 85 Nm torque and an intelligent eMTB mode with Extended Boost, which automatically adjusts the support level to the terrain. Bosch LED Remote The LED Remote of the Bosch Smart System allows you to conveniently and intuitively switch through the support modes, activate the push assistance, or turn on the optional lights. The bright LEDs, which are optimally visible in all lighting conditions, indicate the battery level and the current support mode. Bosch Kiox 300 Display The Bosch Kiox 300 is a robust and compact full-color display that clearly and easily shows all important ride data such as pedal power, motor power, speed, remaining range, and more. Adventure-ready accessories The Powerfly Equipped scores high with its factory-installed accessories for maximum utility. The equipment includes a bike stand, front and rear lights, fenders, and a special rear rack that perfectly integrates into the design. A better method of aluminum production In 2024, we began to remove emissions-intensive aluminum from our production and replace it with low-emission aluminum produced using renewable energy. By October 2025, nearly all aluminum bikes we manufacture—including this model—will have been converted, resulting in a significant reduction in our CO2 footprint.
