Sometimes when you are on a bike, cars don’t seem to care about your safety. Well, you could get mad about it or you could throw one of these magnets at the offending vehicle. It lets them know that they’ve acted like a jerk and calls them out on their behavior.

The card is designed by Peter Miller for cyclists. Just hurl it at the offending car and it will stick, without causing an accident. Later, the driver will feel bad. Rightfully so.

GPS navigation systems aren’t just for drivers anymore. The Garmin Edge 800 is for cyclists who need accurate information in the simplest way possible. It merges the most popular aspects of the Edge 500 and Edge 705 along with an updated intuitive touchscreen interface.

New mapping options include Garmin’s BaseCamp route planning and BirdsEye Satellite Imagery and the Edge 800 is smart enough to track all performance data, so you can view it over a 2.6” display while keeping track of speed, distance, time, GPS position, elevation, calories burned, climb and descent.

Turn signal gadgets for cyclists is nothing new, but you don’t often see them in clothing. Ph.D student Leah Buechley on the other hand, has designed several items of electronic clothing, but her signal jacket for cyclists really stands out.

LEDs are embedded in an arrow formation and they flash to indicate that you are about to turn left or right. That’s a good idea since it will warn motorists, and prevent you from becoming roadkill, which we know some rednecks eat. The LEDs are powered by the round device in the center of the jacket, which is a small, sewable computer chip that Leah also designed herself. She obviously needs to be working with clothing manufacturers.
