The Powerfly 4 625 is built on our most affordable E-Mountainbike, but it comes equipped with a larger 625 Wh capacity battery. Of course, the bike still features our RIB system (Removable Integrated Battery), allowing for easy removal and reinstallation of the battery. Additionally, it includes all the components that make the Powerfly 4 the perfect entry point into the world of E-bikes, whether for on-road or off-road riding.
