From now on you can rent one of the over 6000 (so far) bicycles that are available for the public in over 300 stations over Manhattan and Brooklyn.
Although the bikes are for rent from yesterday for members, it is only from 2nd June that the tourists can get them for short journeys. The price is quite ok, 9.95$ plus taxes for 24 hours (although in London the price is 2£) and you have to dock the bike at the station every 30 minutes to avoid paying a surcharge.
New York has more than 400kms of bike lanes and over 300 green routes. These made it the perfect city to explore on two wheels. But please, take care when driving!
