E-Mountain bikeshave found their way into more and more cyclists’ life. With the help of e-power, riders are able to adventure further and ride more aggressively.
However, with more components added (motor, battery, etc), the weight of e-bike is normally much heavier thanregular bikes, which means more workload on the wheels.
Thus, carbon rims for E-MTB should be of better strength and impact resistance than regular carbon MTB rims.
ProX carbon rims for e-bike are with more layers of carbon pre-preg added to the whole rim and extra reinforcement for spoke hole area. Applying the latest lay-up and manufacturing technology to make the rims stronger, stiffer and more durable.
To make sure our carbon rim are strong and safe enough to be used for e mountain bikes, we do strict UCI impact testings. The detail of such UCI impact testing can be found in below table.
