It has optimal (side) visibility with 20 red bright COB (chip-on-board) LEDs. These smart COB LEDs have a switchable wake-up function, so that the rear light goes into sleep mode after 4 minutes of standing still and will automatically turn on again after sensing vibrations. You can easily pull the rear light around the seat post using the elastic rubber band. To ensure that the USB Spider fires at the correct vertical angle to the rear, it has an angled design. The USB rechargeable rear light is fully charged within 2.5 hours, thanks to the USB-C cable supplied as standard. Furthermore, the USB Spider has a smart battery indicator and has the German StVZO approval.
