Despite frequent complaints and fears about bike theft in the city, many urban bikers do a crappy job of securing their own two-wheelers. Now, mechanic Hal Ruzal of New York’s Bicycle Habitat is grading cyclists on their lock-up job — and also educating eco-travelers on how not to get their bikes stolen.

I’m not that embarrassed to say I’d probably get a C- or so from Hal. I use a cable lock and put it through both wheels and the frame — but my seat could be easily stolen, and I’m guessing the fact that I don’t use a U-lock is also not good news — though I’m not sure of the exact reasons why.

Do you? And how well do you lock up your bike?
