Hi, I know it is a stupid question but I really really need help.

I bike to school and for the past week some people have been letting the air out of my back tyre and i cannot think anyway to catch them, or stop them.
I was wondering if you guys knew anything i could do to stop them getting my dustcaps off or letting the air out of my tyre.
Please help me as it is upsetting having to walk all the way back to my home.
Thanks

Somehow lock a bike pump onto your bars. Or put a hidden camera by your bike, then when you find out who it is, beat the crap out of them.

locktite your valve caps on, just have a pair of pliers when you need to take em off...

I don't have any idea if that'd work, just throwin' it out there

Oh, or maybe try some of these locking caps.

Why would you do that when they'll probably start popping his tires instead. Put your bike somewhere else and tell the teachers.

I still like the hidden camera idea.

put your bike next too other ppls bikes and see if they do it to their bikes. if they do, form a lil gang and tell them to stop, bullies are afraid of numbers. but if they dont.....tell a teacher
hope that helps

The new bicycle security system from Master Lock.

Ride your bike to school. Skip school and hide in the weeds by your bike. When you see someone letting the air out of your tires kick their ass.

That's funny, because I gave eight kids wedgies today, simultaneously. Then I took their lunch money, all of it.

(yah, okay)

It's Beerman, expect the unexpected.

im all for raleighs idea. hide in the weeds and whoevers doing it, sneak up behind him and knock him out with a sleeper hold. then while hes out, kick in the balls a few times. he wont mess with your bike again. EVER. hahaha
