I've been thinking about this problem for a while and I'm not sure how I'm going to solve it since there are too many homeless people around my neighborhood willing to steal anything thats not chained down to a porch. I keep coming back to some sort of quick release pedals so you just take them off and throw them in your pocket (or even one). Maybe put a U-lock in between the rear wheel and the frame to keep the rear wheel from moving. Or even a locking kick-stand that requires a key to flip-up into the standard driving position. Me and a coworker were discussing how to make "The Club" for a bike that would make the handlebars and hand controls inoperable; only problem would be the weight of having to carry out on you while riding.
I'm going to detail my build hardcore from the start and I've got a couple of other anti-theft ideas. Most of them really will just make the bike impossible to dissemble without the proper tools (have bolts with a couple different Torx bit heads, various sized Allen wrench sockets, etc).
Check with Turbo/Chaos, he was working on gettin some "bike alarms" how efective they are I donot Know. Im planing on putting in a key switch in the ign circit, like the old car alarms. Alot of the people around here take their seat with them when they park their bike. That seames to ackt as a crime prevenitave( or free rectal exam)
BTW i live in a collage town we have alot of bikes here, also alot of bike theft, not somuch by homless, but opertunist.
I live in Texas 87f at night 103f in the shade during the day no wonder I cannot sleep. Its no wonder why violent crimes drop during the summer aruond here , its to hot to beat someone up. "let it rain, let it rain, let it rain"
you guys have it easy down there. im in CT where the gulf stream slams into new england. imagine 90+ with 90%+ humidity. my cousin just moved up here from frisco and he was telling me summers here are brutal compared to there.
One of the most interesting and effective bike locking methods I've ever seen was built by an engineering student I was in school with - he'd had three bicycles stolen in three months - all by cutting his chain/cables.
So, he bought an older bike and stripped it to bare frame, then put a case hardened rod through the top tupe that inserted into a socket he formed in the fork stem; same thing ran down the seat tube to the bottom bracket and engaged the crank, when extended. Both rods were invisble inside the frame tubes - just under the seat he put a cylinder with a keyed lock in it - you straightened the forks, made sure the left pedal was at the top, then turned the key. Both rods would extend, and it was impossible to pedal or steer without unlocking it.
Three times after that he had his chain cut, each time he found the bike within a 100 yards.
