Which locks have the best weight to security ratio?
In other words, I want a "lightweight" lock which will withstand theft
attempts. Thanks!  |

Normally you can pick two of strong, cheap or light; but in the case of locks I don't think you can get stronger and lighter by increasing the amount of money you're willing to spend. The closest I think you can get is to buy big strong heavy locks to leave in all the places you want to lock your bike up. I'd like someone to prove me wrong here. |

Up to a point you can: you can make a high quality steel lock at less weight than a crappy mild steel one that is quite a bit stronger, for example, but you can only go so far down that road. All else being equal, a heavier lock will resist more serious butchery. > The closest I think you can get is to > buy big strong heavy locks to leave in all the places you want to lock > your bike up. > > I'd like someone to prove me wrong here. The lateral thinking approach is have a folder which you don't lock up, but take it in with you. Works in most places most of the time IME... but that may not be enough :-( Pete. -- Peter Clinch Medical Physics IT Officer Tel 44 1382 660111 ext. 33637 Univ. of Dundee, Ninewells Hospital Fax 44 1382 640177 Dundee DD1 9SY Scotland UK net p.j.clinch@dundee.ac.uk http://www.dundee.ac.uk/~pjclinch/ |

Re: Which locks have the best weight to security ratio?
Master Lock Street Cuff -
1250grammes according to an ebay power seller. The Trelock Folding Cops - 900grammes according to another powerseller /What do you guys think of this/ http://i14.ebayimg.com/06/i/000/e8/11/016e_1.JPG Raleigh armoured cable lock - 500grammes My current bike (Raleigh Folder) isn't expensive enough to attract hardcore thieves.. (I don't think). Also I don't leave it outside overnight. However I plan on getting a flashy looking Specialized Sirrus soon.... |

Not only do flying pigs not make good locks, they also get immediately stolen - after all, when was the last time you saw a flying pig (locking up a bike or otherwise)? Tim. |

Whilst it'll be easily broken through with an angle grinder so will everything else. The plus points are that the hinges prevent a thief getting a bottle jack in, or from getting two parallel edges for it to push against. It's also compact in your bag. Combine this with a second lock decent lock to protect the front wheel and prevent them from levering the lock apart (with your bike as the lever). This is important because if try and fail to nick the bike this way you'll be left with a dented, possibly borked, frame. Still not light tho. |

All three will be defeated very quickly with bolt croppers or portable angle grinders. The Trelock and Raleigh look like they have vulnerable locks that would succumb to serious poundings with a lump hammer. |

Paranoid owners will not leave locks behind as they signal a fixed parking spot for cherished bikes/motorbikes. Theives have all the time in the world to try picking the lock in the absence of the bike or squirt superglue into the lock rendering it useless. Both nobbling methods have been reported in motor cycle comics. |

I'm in Belgium, here, most bikes seem to come with a lock that sits just under the seat. I'm sure someone here must be familiar with it. When you want to lock-up, you turn the key slightly and push down a knob/lever. A curved bar comes out one end and into the other between the spokes (spelling?) of the wheel. When the lever is fully down, the key is released (can't get it out otherwise). On return, insert key, turn slightly and the lever pops up again releasing the back wheel. Because the key is 'stuck' untill next use, you never have to 'remember' to bring it, which is also handy because you can attach the key for another cable lock. Only problem being, I've never tried to smash one of these rear seat locks so I've no idea how good they really are. |
