LuminKing Bicycle Spoke Light with Motion Sensor - Featuring 30 Color Patterns, Auto-Update Every 4 Seconds, 14 LED lights, Easy Wheel Spoke Mount, Waterproof, Batteries Included

The bike spoke light looks great, especially in low light.It is really easy to install onto the spokes, it only takes a minute to screw it on. It is powered by a regular AAA battery, which is included in the package.There is an on/off switch, and when left ON, it will automatically turn on when the wheels are going round, and then turn itself off after a show time not moving.There is only 1 light in the pack, so will need another to light up both bike wheels.

Comes in a pack of 1, so you have to decide which wheel gets the light and which goes without.Uses an AAA battery which is far preferable to button batteries.The light attaches easily using a plastic bracket, which is lightweight but not the sturdiest as the screws are also plastic.The light turns on with a long press and the patterns light up pretty well, especially if you are cycling quickly.A fun novelty for cycling in the evenings or in winter. My 10 year old thinks it’s really cool.
