I would love to see the city’s proposed budget for this operation, and see how many bikes they expect to have stolen per month. Increase that to the number of bikes they’ve got, and you probably are closer to the end result.
This program is privately financed.
I doubt that bike theft is going to be a big issue with this program, either. The bikes themselves are big, heavy, ugly, pretty distinctive, and have built-in GPS trackers. Bike theft rings in NYC (and often elsewhere) are often pretty sophisticated, and in terms of risk-reward, stealing these bikes probably isn’t worth it.
