Riese & Muller Powertube Battery Cover

This is the rubberised cover that comes attached to R&M powertube batteries (since 2019 onwards). You may need this product if your cover has been damaged/lost or if you are purchasing a spare Bosch powertube battery for your R&M and would like a cover for it. Note that you don't need this cover in order to use a Bosch powertube battery on your R&M - you can simply put the battery in and ride around and it will work, it just won't look as nice or be as weatherproof.

Tools and patience are required to install this cover. We would recommend against taking them on and off for temporary use of a spare battery, easier to just ride without the cover for a period of time.

If you are looking for a cover for the hole in your frame that is left behind when you remove your battery, then that is a different item for a different purpose, despite looking very similar to this one. You can view that product here.
