Powerfly 5 is a highly capable electric mountain bike for a great value. It pairs a high-end Bosch e-MTB drive system with durable mountain bike components built to stand up to the trail. Plus, it features our user-friendly Removable Integrated Battery (RIB) system that fully encases the battery in the frame, yet doesn't require tools for removal. This bike is versatile, capable and ready for adventure. Will my bike have a curved top tube? Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height. 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. 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. What is the range?
