PowerMore 250 is the bottle-sized additional battery for even more range and longer-lasting trail fun. Compact and weighing just 1.5 kg, the range extender can be easily mounted on the eBike using the battery holder. The cable set must be ordered separately. Quick and easy retrofitting is possible, and it is compatible with your existing Bosch eBike battery. The included bottle holder provides a simple way to switch between the range extender and a water bottle. The PowerMore can only be used if there is a manufacturer approval for the respective eBike, as the battery cannot be operated otherwise. You can check whether the corresponding approval is in place via the DiagnosticTool 3, the display, or the FlowApp. More information can be found in the Bosch eBike PartnerPortal or in the Help Center on the Bosch eBike website.
