Buy a used bike. There should be plenty of used bikes for sale in that area and they should be fairly inexpensive. Then buy a decent lock but not a cable lock unless you use two locks which is what I recommend anyways. Your first primary lock should be a large U-Bolt from Krytonite.

And here's a web site to show you how to properly lock your bike using a long U-bolt: http://www.missinglink.org/page/how-lock-bike there is one flaw with this locking method, if they cut the rims they got the bike, thus make sure that both rims are locked as pictured but run the U-Bolt around either the seat tube or one or both rear stays depending on what the U-Bolt will fit around.

Then as an option, which I would do, is to buy a the thickest cable lock system you can find and run the cable through the wheels and frame to the bike stand. Two forms of different type of locks will stop a thief since they won't be running around with two sets of tools to use.

But none of these locks will stop a parts thief, so you have to find out if part theft is a problem there, if so then you have to invest about $140 in a complete parts lock system from PitLock that locks your wheels (though the U-Bolt will do that too as does the cable), locks your seat, your forks, and your handlebars.

But if you buy an inexpensive bike with relative inexpensive parts a thief won't be inclined to steal yours, they'll just move on to the rich dope that rode his $3,000 plus bike in parked next to yours!! Thus buying the PitLocks may not be necessary. Make sure though that you take your pump, computer, and lights off and put them in your backback or else they will be gone the very first day.
