I went with my sun (15y). Starting: green (new) bikes on the street but not a sign of a bike company. But the tour guide knows and will come to you! So no worries about that. Our tour guide Darwin was perfect. Balanced perfectly between story telling and site seeing and biking. We had a little stop at a restaurant where you can buy a drink or/and relax a bit. I would definitely recommend it.

This was a perfect tour! Be sure to do this early on in your trip so you can have a general idea of where everything is. It was a perfect balance of sight-seeing and physical activity. The bikes were light-weight and great! Its so much better than a walking tour. You cover a much larger area in a much shorter time in a cooler way.

Other than the fact that my tour was postponed to the next day without me knowing, the overall end result was rather satisfying. The bikes can seem unconventional at first bur they're comfortable enough. You are guaranteed to see the most popular locations that you can always come back to any time later during your stay (in Stockholm). Very good route.
