In the third world utility bikes removing the rear wheel involves removing the rack, fender stays and uninstalling the brakes. The front wheel is almost half as complex with the rod brakes.
The horizontal dropouts with chain tensioner nuts need slipping the chain off the sprocket and removing the wheel in the rear direction.
Sometimes, all this is held together by a natural cement of dirt, grease and rust.
Leaving the wheel attached and just working on the tube is much easier. Roadside bike flat fixers used to sit under a shaded spot with a few tools like a pump, a pan of water, a stove top or electric vulcanizing iron and some vulcanizing cement and patches.
