Just one more way in which the car culture screws bicyclists: traffic lights. With the advent of inductive loop traffic sensors, traffic lights suddenly knew when there was a car waiting to go, and could keep the light red until there was a car. But that means indefinite waiting and eventual required law-breaking by bicyclists.
Well, screw them. Watch the video above and learn. Strap a simple inexpensive neodymium magnet to the bottom of your bike frame and, voila, you're now a recognizable presence in the automated car culture.

You could get off your bike and lay it flat against the ground. In most cases, that will be enough to trip the inductive sensor.

I used to think the sensors worked by detecting the weight of cars, and that my bike and I just weren't heavy enough. Good to know I can set them off with a tiny little magnet, instead of having to bulk up!

If you're on a motorcycle you can trip the sensor by putting the kickstand down...

Let your local municipality know that you want bike sensors. They can lay them down (and retrofit) so a bike will trip them. And encouraging bicyclists is much, much cheaper than widening roads for growing traffic capacity.

Checked all the web sites and could not find the magnet used here.. tries a ferrot iron one and it did not work, may not be powerful enough... Any help on where to get a couple of these?

Though the car and bus, this soriety can't leave them,but the bike maybe is more batter than any other car or bus,because it can keep a good entironment.

There are no solutions about bikes rust. It's too dangerous for foot passengers.

There are no solutions for bikes rust right now. So it's too dangerous for foot passengers.
