or How Many State, Federal and Local Authorities Does It Take to Stop Bike Theft In An Enclosed Area?

How much theft can one person do?

There is a lock used in europe that seems interesting.
There is talk of a weakness in the lock keying design though.

There are some good locks out there and hardened alloy chains that are light for their strength and essentially cut proof in larger sizes.
GPS is now much cheaper and included on some new bikes.

Or you can always leave your bike in the shed of someone on the west coast.

Fish don't need bikes.

Bikes dont need fish either

I've seen some bikes shaped like fish.

I ran across this interesting variation on chain.

And the frame mounted locks are pretty common in europe that lock the wheel.
Some versions are said to be too easy to defeat.

When I had a break-in the day I left for burning man last time, I suggested to the cargo task force that they start using trackers on bait trailers.
I just found out that they took my suggestion.

interesting possibilities here perhaps. http://setthehook.com/icefishing/tipupl ... thouse.htm

I kind of like the idea of a light show and music set off by a trigger, light beam broken or something. It would be fun to see it set off. maybe get one of those record your own greeting cards and amplify it.... help I am a bike and I'm getting stolen! Those just have a separation switch don't they?

also there are those window alarms that are just two magnets that set off the alarm when the magnets are separated. could put one on the wheel and one on the fork. That could be the trigger, I don't think I'd like to actually hear an alarm like that. and there's a mailbox alert that could possibly be modified for a bike. this has a remote reciever that has "pleasant chime sound?"
http://www.preventsecurity.com/productd ... =86&p=2101

I use a thin cable about two feet long that is sold for locking a removeable seat to a bike frame. It is light. At home, I pass this through my helmet and bike seat and run it to my larger cable and lock. I don't think anything is theftproof, but making it a little bit difficult sometimes gets a thief to move on to the easier target. This alarm stuff sounds like fun to me though.

I like my bike, but I bring one that I could stand losing. I also wouldn't be in a rage about it if it went missing and I hadn't locked it.

Just don't pay a lot for any bike you bring to the playa, and be prepared to walk if needed.

unjonharley · Post by **unjonharley** » Sun Sep 20, 2009 9:15 am

i've posted this before but..

long about dusk/dark.. set a bike out.. attach a 50 foot cable to the lower frame.. rebar the other end to the ground.. just sit back and watch the fun.. when you have to go pick up the bike.. you say.. gee looks like my bike.. wounder how it got out here.. reset the bike for the next ass hat.. invite other campers to bring there lawn chairs and enjoy the evening with you..

Anybody remember "Stand by for justice!" in the film American Graffiti?

Those locks that are attached to the frame were common when I grew up in Norway. Very quick and easy to use.

LOL I might try that next year! Would rope work as well as cable?

So long as it is difficult to see, and still strong enough to stop the bike instantly.

Even better, would be to fabricate a front hub with some kind of clockwork mechanism inside, so it can roll say, 20 revolutions, and then lock up solid!

I'm thinking that this could be done with a rear wheel coaster brake hub, which already has a braking mechanism.

Elorrum · Post by **Elorrum** » Sun Sep 20, 2009 11:39 am

how about like the security system on grocery carts? distance from receiver or transmitter and the wheels are locked.

purely mechanical would be better. lets say two spools, one turned by the hub, one fixed to the frame with cable payed out onto the turning spool. when the spool was empty of cable, the wheel wouldn't turn anymore. give em enough rope to get up to speed. It's the same principle as unjon's original (probably still the most elegant in that it is easily made) but the cable would be contained on the bike. the front wheel gives the best acrobatics. put the pay out spool on the handlebars, in a basket perhaps?

or a big cam, widening sprial... several revolutions.... click click click (duck duck duck duck...) then a bigger notch to brake (GOOOOOOSE!!!!)

So - I turned a couple of old stun guns and bike seats into remote controlled ass shockers. Wasnt ready for thie years burn but now they are.

Sure enough my bike got "Joy Ridden" to somewhere else or stolen outright.

Any one see criminal liability on my hands if I set up a couple of bait bikes and shock them in their chode as they ride off. The perp will surely hit the ground like a sack of shit and may even hurt themselves. I plan on videotaping them and posting to youtube as well.

any lawyers out there got an idea?

Post by **Elderberry** » Sun Sep 20, 2009 1:35 pm

First, it's burning man. Second, you are entitled to lock and/or protect your property. It would make an interesting case at the very least, should it ever get to court.

If the "read the back of your ticket" works for the slide, it surely should work for your most creative bike protection system.

Hell anyone that got shocked or knocked off a bike that had an unusually long teather was stealing it to begin with. If they wouldn't have tried to steal it, they wouldn't have subjected themselves to the protection system.

Elliot · Post by **Elliot** » Sun Sep 20, 2009 2:06 pm

Elorrum; you and I seem to be thinking alike here!

All right -- I have disassembled an old Sturmey Archer three speed coaster brake hub, and I'm pretty sure I have figured out how to make it apply the brake after approximately ten revolutions. The key is to use all-thread for the axle.

Might be easier to do with a single speed, but the three speed was the first coaster brake that tumbled out of the garage when I opened the door.

Work continues after lunch.

If I have trouble with this one, I can always yank a single speed wheel off a bike.

This is an impressive idea.

Elorrum · Post by **Elorrum** » Sun Sep 20, 2009 2:40 pm

maybe the bike should have written on it somewhere, "Fuck You Bike" property of "xxx" so it's obvious that to take is to steal it.

oh hell....

c'mon sing with me! oooo ooooo ooooo! what a little mayhem will dooo ooo ooo!

Elliot, all thread, I like where you are going with that.

Sail Man · Post by **Sail Man** » Sun Sep 20, 2009 2:47 pm

Why 007, that sounds like a devilish splendid idea

I would def. pull up a lawn chair to watch those festivities

Gyre, did you use the chain and lock you were talking about earlier, and if so how did it fair?

gyre · Post by **gyre** » Sun Sep 20, 2009 3:12 pm

I canceled my chain order when we fastened the generator to an I-beam.

I didn't expect to make it this year, so I was caught off guard when it happened.
I went to my supplier to get some chain and U-locks and they quit stocking due to the economy.
I brought a shrouded lock and some lesser chain and bought a U-lock in Reno.
I was dismayed at the incredible lack of choice at any price.
I used the U-lock exclusively and someone tried to steal my bike very aggressively at the second place I stopped, the Booby Bar.

I'll be using a ground anchor for my new bike here and chain and padlock.

After seeing how poor the selection is, if anyone wants to do a group buy of locks and chain, I'll do it at cost.
Your best option is a locksmith, not a bike shop usually.
Let me know what you guys are interested in.
By the way, it has been mentioned to me that most bikes are stolen from inside homes so it is advised to lock up inside too.

I can get the Abus chain from 6mm to 14mm in custom lengths.
I can get anything from Masterlock/American, Abus, Assa, and a few others whlesale.

And here we are. Mind you, this is just a prototype. Then again... it seems to work!

Just a random coaster brake rear wheel, attached to the front fork of a random bicycle.

But...

...there is some fun inside, where the axle is now all-thread, and a nut has been welded to the cone that applies the brake. There is also a tab of flat stock welded to the nut/cone, and an other scrap of flat stock welded inside the hub barrel. When the wheel turns, the tab in the hub catches on the tab on the cone, and the cone goes around with the hub -- screwing itself along the all-thread until it applies the brake.

I get about eight turns out of this one, and that should be something like 40 feet. The brake comes on a bit slowly (because the pitch of the all-thread is so short, compared with the original â€œbendix driveâ€
