In general, PowerMore 250 can be ordered as a retrofit product at your eBike dealer. You also need a cable that needs to be ordered separately. You can find out the right cable length from your eBike manufacturer or at the eBike dealer.

Whether you can upgrade the additional battery PowerMore 250 to your eBike, you can learn from the dealer or via the eBike Flow app (Settings > My eBike > eBike Pass > Components). If you use an eBike display, you can find out via Settings > My eBike: If the PowerMore menu is displayed here, you can retrofit the range extender.
PowerMore can only be used if a manufacturer’s approval has been granted for the eBike in question, otherwise the battery pack cannot be operated.
