A simple cheap (lockable) canister for your bike

I like this build, basically the author uses a pvc pipe with ends, cuts holes in it to “lock” it, and bolts it onto the bike.  One thing I would do different is reverse the ubolt (use a square bolt instead) so that a determined thief would not just unbolt the thing.  Of course I don’t think I would use the seat bolt either as my seat usually comes with me (its removable).
