Hi Nadia … Yes… It’s always good to remember where did it start because two years ago I didn’t think about cycling as mobility (more as a leisure activity) until I moved to Berlin and got my first cycling-culture shock 
It’s not only the number of cyclists that caught my attention but also the planning culture that is a bit different from what we have in Egypt … the year I moved to Berlin there was the Fahrrad Volksentscheid (a city-wide petition making a political pressure for a better cycling infrastructure and laws) and the Radbahn project that is a bike way designed by a group of volunteers to utilize the space under the U-bahn overpass.
I used to complain about traffic like everyone else in Egypt but then I realized that I can actually try to do something. In Berlin, you can legitimately raise a petition to change the law and the infrastructure on ground. In Egypt, that’s not the case so you have to find your own way either by being part of the civil society and/or private sector or to try to reach out for the decision makers. The civil society is now moving to spread the cycling culture among the youth but it doesn’t speak the same language that the decision makers do… there are always questions about the economic viability and skeptic voices questioning adopting the European experience in a very different socio-economic situation … so I try to answer these questions (is it be economically beneficial to the individual and the city? what can the private sector do? what can we learn from places with comparable socio-economic conditions? (Latin America for instance)
