Some of you will be familiar with the Sheldon Brown locking method; the U-Lock goes through the back tire and the bike chain, but not the frame. Here’s what I think, his idea is not sound, I could cut through a rim and tube with a hacksaw and clip the chain in about 1min, bend the rim and remove the bike. Can anyone convince me or tell me why this method should offer a cautious biker security? Tell me what do you think is the best and easiest method and why don't others work?
(Also, I would not be suprised if bolt cutters could make lite work of a frame, tube and chain.)
