A direct swap to a larger Bosch battery - for example from the PowerTube 625 Wh to 750 Wh - must be checked individually.
The batteries differ in length, plug connection and system approval. Many frames are designed and manufactured precisely for the corresponding battery sizes.
However, some models have an adapter built into the frame to compensate for the smaller battery. If this is removed, it may be possible to fit a larger battery, but only if the frame is designed for this. Your Riese und Müller specialist dealer will be happy to check this for you.
Riese & Müller does not recommend customised conversions. For more range, an official range extender or a second battery pack are suitable instead. An unauthorised battery swap can affect the warranty, guarantee and safety of your bike.
