Bike repair, street-style. Every few blocks in Shanghai there are repair shops like this, working on bicycles, scooters and electric bikes. Everything from putting air into tires to welding frame repairs, all done on the sidewalk. Parts are kept in little containers, all rusted and corroded but usable. Tools and techniques are a bit crude but suit the level of machines in use and more importantly, are effective. Bikes are for transport of people and goods, not for sport. And always, a big tub of greases.
