The Rollz Motion light makes sure you are visible in the dark. At the push of a button, both lights go on, illuminating the path in front of you and the people behind you can see the red light. The lamp can be charged with the supplied charging cable and is mounted standard for attachment to the right frame part, but can easily be fitted for the left frame part using a Phillips screwdriver. This lamp fits the Rollz Motion, Rollz Motion Performance and Rollz Motion Rhythm.
