Crime does not scale. It's the same few people stealing the majority of bikes. I'd go as far as to claim almost no thief steal only one bike. Catching thieves and jailing them scales. For each one caught you avoid potentially hundreds of further thefts from that person and an even greater number from the people who will be discouraged from pursuing criminal activities.
