We took the tour with 6 friends on the 3rd of November 2012. It was a great tour and very exciting to take the bike in the very crowded city! The Turkish people were amazed to see people cycling in Istanbul! The guide is very friendly and glad to help you out with tips for the rest of your stay in the city. Just a recommendation for improvement is to ask the group before the tour starts what the expectations / wishes are. This was a great way to explore the city, far better than big touristic buses.
