Bounties attract serious brainpower to the challenge.
A security mechanism that makes your bike appear broken as soon as you leave it behind. Anyone trying to steal it would find it unusable.
Theft prevention that takes the least amount of effort from the owner.
A fun way to mess with thieves while you watch from afar.
Leave the bike anywhere for brief periods.
How it works
Some of the bike's critical moving parts are held in place with pins (miniature linear actuators) that are not visible from the outside. The parts can rotate uncontrollably if the pins are pulled out of their holes. This renders the bike inoperable until the pins are re-secured.
If someone tried to ride the bike with pins detached, it would feel like this:
When you let the bike idle for a while, it goes into security mode (turns limp). In order to get it to work again, you find a barely noticeable button underneath the seat and press it repeatedly with the pattern you've memorized.
I thought about a few extra features that complicate the design. Although they are probably overkill, the seat and the peddals could be made to fall out of sockets and held in place with a steel cable.
The frame is embedded with a GPS device that's recharged by pedaling. A GPS saves power by transmitting a bike's location only when stationary and at a new location.
Very cool video and the idea of making a bicycle theft harder.
I have two questions.
In which places would you put the pins? I guess the only moving parts that are critical for driving the bicycle are the steering wheel and the pedal systems that get the bike moving. However, these systems are tricky to modify. One pin could be there to make the pedal system rotate without transferring the movement to the chain. The other could be controlling the steering wheel like in the video you linked. What do you think?
How would this pin work? The idea is great but I still can't imagine these pins actually working. Did you have in mind an exact system of where would the pin be placed and how would it serve as a switch?
