With a permanently attached silicone mount, the StVZO front light is light weight and simple to install on any handlebar.


  • Integrated silicone bracket
    The ROADSTER USB features a permanently attached silicone bracket. This makes it simple to attach to any handlebar, even oversized or oval shaped bars.

    The large click switch is easy to operate: double-click the switch to turn the light on, click once to switch between lighting modes and press and hold to switch the ROADSTER USB off again.

    The ROADSTER USB is impressively light, weighing only 72g!
  • Splash resistant pursuant to standard IPX4
    The ROADSTER USB is naturally windproof and watertight. It is also splash resistant pursuant to international standard IPX4 and therefore ideal for everyday use.

  • 25 lux – two modes
    With 25 lux in standard mode and 15 lux in eco mode, the ROADSTER USB has the perfect amount of light for any ride.
  • Li-ion battery with integrated micro USB charge function
    Thanks to the integrated lithium ion battery, the ROADSTER USB can be recharged at any time and anywhere using the micro USB cable provided.
  • CREE LED – beam range 30 m
    The CREE high-power LED is among the best on the market. In conjunction with the optimized SIGMA high-performance optics, it enables the ROADSTER USB to offer an outstanding lighting pattern with a beam range of up to 30 meters.
