U-Lock Bike
Half of the diamond frame, from the seat post to the front wheel, opens like a U-Lock. | |
This winter I've resorted to leaving my bike unlocked at the various places I have ridden it to. This is partly due to the poor condition of the beater and that the cold weather has rendered my steel cable lock immalleable. Despite its low monetary value, I still worry that it will not be there when
I return to where I had left it.
For peace of mind alone it would be worth buying another lock, however the only other locks available are much more bulky; these include chain locks and U-Locks. The most desireable solution would be not to have to carry a lock at all.
The Lock Bike is a new type of frame design that turns a bicycle into an oversized U-Lock. This frame is made by cutting a standard diamond frame at both points where it connects to the seat post. Then a hinge mechanism is welded in place at one point, and a locking mechanism at the other. A key allows access to your bike which can be found locked to a bike rack, wide diameter tree, or other similarly suitable structure.

Here's a prototypical drawing.

I can't see how this wouldn't make your bike a lot weaker. It might also mean you'd have to throw your bike away if the lock broke or you lost the key. |

This is about riding around on a giant lock, not about being sensible. |
|
| |
Cars and motorcycles have built-in locks, and so should bikes. + |

Do a little search before you post. Sheesh. |
|
| |
I didn't search, but its not exactly the same idea. This is for a bicycle U-Lock. |
|

Sounds a lot like [mac cartel]'s idea. How does it differ? |
|
| |
The bike would open up like a U-Lock instead of just having a sliding bar. The design in completely different. The user would be able to unlock the bike and the frame would essentially come apart and twist at the hinge. However, to quote Mac Cartel ""obviously not as original as I thought". |

OK, I think I get it. There's a bike locked to a post about two blocks from here. It's been there two years. I might see if I can cut it loose and modify it to do this. |

I just made a kind of collage to illustrate the general principle [link]. It had been so long since I had a U-Lock that I forgot that they just come apart. This would be a bike that seperates in half and joins together again. |

This'd be harder and heavier to make workable than you think, what with rattly joints and all. It'd also be harder to use than a U-lock, as you'd have to get the bike horizontal to go around a lamppost, and it would not fasten at all to many bike racks. But it would make a nice folding bike--check some folder designs for hints. |

Good luck getting that bike, [UB]. I remember happy college days of salvaging abandoned bikes. |

How about a slip-on silicone-rubber seat
cover that looks like someone's thrown up
on the seat? I suspect that would deter
most theives. |
