Anecdotal: I've had more cars than bikes stolen (6 cars, two bikes if you include my daughter's).
I found some data for the UK: each year, ~2.7M cars are sold [1], and ~70k stolen [2]. In the same time, 3.5M bikes are sold [3], and 400k stolen [4]. In France, there are ~1.8M cars sold [7] vs ~110k cars stolen each year [5]; 2.8M bikes sold [7] vs. 400k bikes stolen [6].
