Stay safe and stand out with the Mathmos Bike Wheel Lights. Screw directly onto your bike wheel valves to create circles of light when you cycle. The wheel wares use high quality LEDs that utilize light/motion sensors, so they only come on when you’re on the move at night.
Lights should only be used in conjunction with standard bicycle lights and not just on their own. Do not fit racing bike valves. Requires three A610 button cell batteries (included).
