Not quite the largest frame mounted Bosch battery, but larger capacity than the stock battery most ebikes come with. Bosch PowerPack Frame batteries sit on the outside of the eBike frame, on the seat tube or down tube. They have a handle, so you can remove and carry them easily and conveniently.

All PowerPacks Frame that utilize the frame mount in the smart system have the same mount. Therefore, you can easily insert a different battery, if the geometry of your eBike allows. Smaller batteries reduce the weight, larger ones increase your range. Bosch's e-bike battery electrical system is certified to UL 2849 safety standards.
