The average persons’ opinions are, as far as I can tell, generally positive on New York City’s new rent a bike program , except for those living in neighborhoods where the racks have been badly placed and those who dislike anything that makes New York look more like Europe. At least one man has found a different use for the bikes when they’re not being used: A free outdoor spin studio for homeless people . Whether this is a good idea or not I don’t know, nor whether the instructor will keep it up, but it is a cheering example of human ingenuity.
