> E-bike Rims
Dedicated e-bike rims, a Ryde invention.
Before the e-bikes became popular at the European bicycle market, Ryde was already delivering improvements to its wheels: the Andra rims. The bigger electric hub motors placed the spokes under a too big angle for regular rims. This especially put stress between the spoke nipple and the spoke, leading often to failure of the spokes. By making sure that the nipple could be placed under the same angle as the spoke, this potential tension spot was relieved.
The trick is not only the angle of the spoke hole. Also the seat for the nipple head is optimized drilling a dimple in the rim bottom, on top of the nipple hole. In that way, the extra forces put on the spoke nipples and the rim bottom by the electric assistance are much evenly spread. This leads to even less failure with e-bike wheels. 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.
