ANDRA SERIES
The Andra rims can be ordered in many different wheel sizes and with the drilling angle for the spoke holes optimized for the hub and application. All Andra rims are built to withstand and carry more load than regular rims and can ideally be used for not only regular e-bikes, but also transport bikes with or without motor support.
