Riding bikes from the rental location to Central Park a couple of blocks in traffic was intimidating at first. I wouldn't do it with kids but once we got to the park it was great. It was a great way to see the park.
Really worth doing to see the whole of the park. Only negatives are, the park is only one way on the roads and bikes have to be pushed on the pavements, we spent a lot of time pushing. The site seeing office is very hard to find. It's between 5th and 6th street, closer to 6th with a black shop front
A good way to see Central Park even tho we did get lost a few times as it is very big. I think we were not very organised ourselves beforehand to work out exactly where we wanted to go and see, which in hindsight we wasted a lot of time, We should have researched the map a little better and worked out exactly which direction we should go.
