Despite the lack of cycling infrastructure and lack of parking spaces in major commercial centers, it seems that almost everyone has a bicycle in Tokyo. Trains are the commuting mode of choice for most residents; taxis abound; buses cater to those that live away from train stations; cars, while not excessively priced, can be expensive to maintain here. But bikes are ridden by people of all generations, from school kids and salarymen to housewives and retirees. The bikes of choice are the cheap, functional and generic mama-chari with its shopping basket and child seat (or two) or the increasingly popular, more expensive version, the motorized denki-chari; compact folding bikes and classic diamond frame road bikes are also popular, while high-end racers are proudly ridden by the weekend cycling enthusiasts. Cyclists interact with pedestrians on the sidewalks and road crossings somewhat organically, while something similar happens with cars on the roads–and it mostly just seems to work.
