More information (from Manufacturer):

Hokey Spokes Hokey Spokes are transparent "blades" that attach to your bicycle spokes. As these blades spin during riding, a computer inside the blades modulates the internal LED lights so that design images and custom text appear.

Hokey Spokes are designed so that they fit virtually any mountain or road bike with a wheel diameter of 24" or greater. Hokey Spokes can be used on front and back wheels at the same time.

Each Hokey Spoke contains a number of designs and messages. The blades can cycle through all the designs or can be set to play a custom text message all the time. Play mode is selected by using one of the waterproof keys located on any blade.
