Tour de Bike Lane is something we usually do 4-5 times annually, We go to different locations and gather alongside bike lanes, cheering on commuters and other fellow cyclists going about their everyday business. We believe that riding bikes is fun & super awesome, and we want to make these people feel like they are athletes in the Tour de France, the Giro d' Italia or any other huge bike race by celebrating the act of riding a bicycle in the city.

We often have people who come through the cheering section stop and ask about what we are doing, then join us in cheering on more cyclists.
