Product Information



Mathmos Bike Wheel Lights

Available in Multi-color or White

Mathmos Bike Wheel Lights easily screw directly onto your bike wheel valves and create circles of light when you cycle. The lights use high quality LEDs with light/motion sensors, which mean they will only come on at night when you're on the move.

They are great fun lights but also aid visibility and therefore safety. They should only be used in conjunction with standard bicycle lights and not on their own.
