By the time you get to the park 30 minutes is gone. The guide neglected to give any safety review regarding bike lanes or walking bikes in certain places. Guide got into argument with another guide from same company over where bikes should be parked at a particular stop. Can't hear the guide when on the bikes unless you ride close to him so his discussion is meaningless unless you are at a stop and huddle. They need an audio system badly due to noise and size of groups 15 riders. Apparently they don't want to spend the money. I would recommend renting the bikes and not doing a tour. Spend your time riding with a little map and enjoy the great park.
It was nice to cycle around Central Park, although we found the Tour Guide a little under-whelming!
The time actual spent on the bike was an hour and quarter only.
Our experience with the tour was not so super. The park itself is great. Although the guide was a little disappointing. We had several tours in English before and we never had the problem of not understanding. This time however the guide was talking so fast and didn't try to make it understandable for not native speakers. He looked like he was not really interested himself and the group didn't follow any more. Some people even left before the ending. He talked a lot, that's true, but the message came not over. So after all, we had preferred doing the bike tour on our own... it would have been much more pleasant. However I think if you have a good guide, the experience must be super.
