Our guide was a really nice guy, but he knew very little about NYC. He usually only stated the name of the building or monument, then moved on. He provided some information that was entirely wrong. A few bikes had mechanical issues during the ride, and he did not know anything about how to resolve those issues. And the ride isn't for everyone. We rode on surface streets with heavy traffic, ran red lights, and often rode down the middle of busy streets. If you aren't very comfortable on a bike, avoid this tour. Personally I had a blast with the riding part. Just not the tour guide part.
