If you live in San Francisco or NYC and have a bike, make some extra cash when you’re not using it by renting out to people who need it through the peer to peer marketplace Spinlister. Rental prices average $18/ day and you get insurance for your bike from the site. You can use the extra cash to start a little savings fund. New York kids, get on this before bike share rolls out… if they ever figure that part out. Come on, Bloomie!
