An addition to bike locks and chains

Old Git On A Bike

I was thinking about bike locks and chains earlier, as I will need to get something for when I get my new bike, and I was reading about how quick it is to get some locks undone, just seconds in some cases, along with chains that claim to be bolt cutter proof, or at least make it hard for them to be cropped.

I got to thinking, what would be good for a bike owner, that would not be good for a bike thief, how about if you had some small lockable arm down near the crank, so that when you park your bike up, you unlocked the arm, this small arm would then swivel out and go through the teeth of the cogs outer edge.

Right then, if someone comes along, pops your lock or chain, jumps on your bike and pedals off, every revolution of the cog would flick this arm back, causing it to pump break fluid up a tube to a specially adapted hydraulic brake where a v brake is normally located, which instead of having brake disks in it, it has a metal rod attached to the piston, whereby, once the thief has made say 10 revolutions of the cog as he speedily pedals away, that would give enough pressure after 10 revolutions to throw the metal rod through the spokes of the front wheel, throwing the bike thief over the handlebars, you might have a wrecked wheel, but the thief would probably (if still conscious), get up and leg it, anyone seeing this would assume he was a thief and call the police, leaving your bike to be recovered.

Sorry, just daydreaming, I had 2 bikes stolen years ago, I can dream can't I :twisted:

This wouldn't stop your bike being stripped for parts which is a common occurence on locked bikes. Also, I don't understand your point about a V-brake without brake discs in - as far as I am aware there are no brake discs in a V brake.

If you want maximumsecurity for your bike you have to carry aroung a wacking great chain. This isn't very practical, so the best you can do after that is probably a D lock.

I have been thinking about this, I had my lock cut 75% of the way through yesterday so i'm very lucky to still have my MTB. Was hoping the next bike they try to steal had no brakes and sent them down the road into a speeding 4x4

I have locking skewers so they cant get at the wheels or seat and I had a decent cable lock but looking at it they were flying through it. I usually don't worry because i leave it in a secure site at work, and when i was shopping at the local mini-tesco there are always loads of people around

Im just going to buy a shite bike for getting around on now, have to stop taking my fun commute in the morning but at least ill be able to keep my MTB nice and safe.

its no good on the street but i keep mine on a rack up on the wall, I think making the loack in a really hrd to access posistion is quite a good idea

on the street you just have to make do with a less desirable bike, which is sooo wrong, feckin chavs

Good quality D lock for the frame and a cheaper chain and disc lock for the front wheel.

Best prevention from theifs though is to lock it in a built up area in full view.

you would think that but mine was locked in a relativity busy area.
