There are two options for how the battery can be installed: horizontally or vertically. The minimalist design offers bicycle manufacturers new possibilities for integration into the frame. The battery is not visible and is perfectly protected by the frame. A comfort feature allows the battery to extend about 2 cm out of the frame when unlocked, making it easier to grasp. Additionally, a safety mechanism prevents the battery from falling out, and it is optimally protected by the frame. Indentations on the top are suitable for attaching bottle holders or design covers. This is the horizontal version.
