When you think about it what is a Joe Citizen going to say? "Errr Sir? Is that your bicycle?" "Of course it is!" The trick as a thief would be to do that but not to show with one inch of your body language that you are doing something criminal... -- underground experts united http://user.it.uu.se/~embe8573 |

I currently have a 5 foot length of steel chain and a padlock that I carry along if I plan on leaving the bicycle unattended. I believe that the price for my length of chain and padlock is probably cheaper then the specially designed bicycle lock. If that's true, then it's futile wasting money on bicycle locks. Instead, one should invest in a bicycle theft deterrent device: http://vengecycle.com :-) Years ago my little Honda motorcycle was stolen and after procuring another one thought seriously about wiring it up to the 220 VAC house wiring and even went so far as to drive a ground rod so any thief would make a good circuit between the wired motorcycle and the ground. Luckily I gave a bit more thought to my electrification project. "get up late, gulp a cuppa coffee, run downstairs and grab the bike...." and so never implemented the project. (But it does have some merit :-) -- Cheers, John B. |

Many thieves discard the frames anyway as they are easier to track/identify than are the components on the frame. Yep, that happens. I'm told that the full bicycle gets a better price, but you're right that components are easier to sell. Yet another great idea down the drain. I suppose that one can glue or epoxy the components to the frame, making it difficult or messy to remove individual components, but that has some obvious disadvantages. Security hardware will prevent the thief from disassembly the bicycle on the rack, but does little once the bicycle has been moved to where he can work on it. One could also design an internal wheel locking mechanism, that prevents the wheels from rotating, but that doesn't stop the thief from removing the wheels or throwing the entire bicycle into the back of a pickup truck. It's a difficult problem that I don't believe will be solvable with a better lock. Cheers Bah Humbug (T'is the season). Actually the solution is pretty simple. Take the subway :-) -- Cheers, John B. |

I don't believe the Blue ones are sold here or at least not through the large hardware stores. -- Cheers, John B. |

The problem faced by the average criminal is to steal the bicycle without destroying it. That's easy when the lock is an independently removable accessory. However, suppose the lock were designed and built as an integral part of the bicycle frame. Cutting the lock would destroy the value of the bicycle making the theft much less profitable. I recall talking to Steve from S&S Torque Couplers. He would sometimes disassemble the frame then re-assemble it around a fixed object. Without the proper tool, it's difficult to separate the frame. http://www.sandsmachine.com That's the obvious implementation. Break the frame and use the coupler to lock it around something. Although it might be difficult to disassemble without the proper tools, I suspect that a pair of pipe wrenches could do it. Reading the web page, the coupler cannot be retrofitted onto an aluminum frame and the process seems to be a custom "machine to fit" exercise that seems to be suitable only for an experienced frame builder. "BTCs are sold only to professional bicycle framebuilders. We're sorry but couplings are not sold to amateur framebuilders. (...) New steel single bike frames add about $300-$750 or more to the regular price of a frame.... Retrofitting your steel single bike frame costs from $400-$600 or more for steel frames." Too expensive and there goes the mass market. Steve told me that it was an insurance issue. He would also not sell to framebuilders that lacked liability insurance. One famous bicycle builder in Sonoma County, for whom the couplers would have been ideal, declined to meet that requirement. |

Those are smaller than the ones I'm used to for this kind of size lock. Also, the keyhole doesn't have a lid so despite being small (the smaller keys, remember?) I suspect some water will make its way inside. When the temperature gets below zero (C), this could be a problem. It seems my intuition was right, tho right now, I'm not happy it was. It is now -4.4°C and it is impossible to get the key inside even one millimeter. I'm boiling water right now and tomorrow God willing I'll get a "winter lock" with the much needed lid and bigger key size. -- underground experts united http://user.it.uu.se/~embe8573 |

Today I tried Sonax, which according to the sticker is exactly what one should use in this situation. It said it was inflammable - probably alcohol in some variety. Didn't work. Boiled water on the other hand worked two times. But it sucks having to do, obviously. And the situation will just reoccur that way. No, one should have a big key, a big keyhole, and a lid on the lock itself. -- underground experts united http://user.it.uu.se/~embe8573 |
