An article published by the Des Moines Register this weekend says that Iowa has slipped a few places in the “bike friendly states” ranking. Considering the vast amount of bikes seen daily, endless biking groups and events, and many bike shops, one can only wonder what the top bike states must be link.
Most bicyclers know that lights are one of the most important safety devices a bicycle can have. If a simple front white headlight and red tail light isn’t flashy enough for you, perhaps you might be interested in something more creative.
There are a number of companies producing LED wheel lights that are able to produce text and images as the wheel spins. These devices use an effect known as persistence of vision, allowing one row of lights to blink rapidly as the wheel spins and create patterns that our eyes see.
Some of these lights produce simple patterns, while others can display full color images, text or even motion video. They all rely on the wheel spinning fast enough to make the effect work (usually around 10-15 m.p.h.), but by adding more rows of LEDs, the effect can be seen at lower speeds.
Simple single-color versions can often be found for less than $10 (including shipping) on e-Bay, and fancier ones that allow loading custom color images are around $40. There are even some that can display animated video. Most are programmed by hooking up to a Windows computer via USB, but some use smartphone apps and Bluetooth.
Here is a chart listing about a dozen different models:
Before we continue with our series on the chainless bikes from Dynamic Bicycles (see part 1 and part 2), we thought it might be appropriate to share some photos of the Runabout 8 (both 18″ standard frame, and some of the 16″ Easy Step frame).
