Jacques Tati - The runaway bicycle

Here's an extract from the 1949 film by Jacques Tati, Jour de Fête. The runaway bicycle segment of the film is sometimes described as an homage to the 1926 Buster Keaton film, The General, which deals with a runaway train. 
   In Jour de Fête, Tati is a postman who struggles to complete his rounds due to the generosity of the villagers who ply him with wine at every stop. A similar scene occurs in the 2008 film Welcome to the Sticks when Philippe Abrams, a post office administrator, tries to set an example of efficiency for his postman. 
   Meanwhile, this extract shows a Chaplinesque exercise with a bicycle.
