I never lock my bike. I know bike theft happens a few times per month because it is the only crime ever mentioned in our kairanban (a kind of neighborhood newsletter). My impression is that only high-end road/mountain bikes or very nice mamachari would be targeted. The easy solution is to ride a $200 Chinese bike and experience the tremendous freedom of taking on the extremely low risk. My local grocery store/mall has literally a thousand bikes parked at any time, and I would say about half don’t even bother with the built-in rear wheel lock.
