We rented 4 bikes at Urban AdvenTours this past weekend. The bikes were in good working condition, comfortable to ride and they had sizes that worked well for my 9 year old, up to my 6 foot 2 husband. They provided us with maps and routes that were a lot of fun. They were very easy to work with and let us just call in to say we wanted to keep the bikes longer. It was a really fun way to see Boston, and bike through Fenway and the parks. Would highly recommend this group of nice people at a very conveniently located business.
