Here is the next installment. I see this little van around the place a bit. As bicycle usage has decreased in Japan over the years (although it may be increasing again lately), local bike shops have been closing down, and your local bike shop may not be so local any more. Still one every 2km or so, so not such an issue really, but these kinds of mobile bicycle repair services are still quite popular. I guess it is just the convenience of them coming to you. Particularly handy if your bike is so busted you can't easily get it to the shop.
Just program the emergency number into your mobile phone and if you ever find yourself in a pickle with a broken chain or puncture you don't want to fix yourself for fear of breaking a finger nail - never fear - just call the man and he will come and sort you out ASAP. The bicycle equivalent of your motor associations emergency vehicle. These guys are fantastic. I imagine these guys could lower overheads even more if they used a trailer like our Chariot to carry their gear.
