I was in town for the Philly Bike Expo 2013. After the first day at the convention i was feeling couped-up and needed a break. I signed up for an afternoon tour. BEST decision ever! Philadelphia is a great city to see by bike since it is flat. The guide was energetic, knowledgeable and kept motivating the group and cracking jokes. Very personable plus he instantaneously remembered everybody's names. With the 2 other guides around, I felt even safer than by foot! Long story short, highly recommended! So much so that i will take a guides tour of my own city!
