CUBE Adapter POWERTUBE 500wh-750wh

The CUBE POWERTUBE Adapter lets you convert your existing e-bike to use a smaller battery with less power and less weight. It’s perfect for securely installing a smaller battery without any annoying rattles. It even has a storage compartment you can use to carry keys or other small items safely stowed away. This adapter will convert the battery compartment on a 750 Wh bike to work with a 500 Wh battery.
