Through advanced COB - LED technology and high performance, striking visual patterns can be created that are unmistakable even in daylight. Mounted on the seatpost, the pre-fabricated angle adjustment of the R-150 optimally aligns the light, parallel to the direction of travel. Thanks to the wide beam angle and specially designed lens geometry, visibility of around 200º is possible, thus providing excellent visibility even from the sides. "Low Battery" indicator light is present when the capacity is approximately 10%. 8 light modes are selectable, including guaranteed runtimes of up to 50 hours.
