A young man, "good and dependable," is motionless after a car accident. Someone decides to psychologically investigate why it happened, questioning people, even discovering a failure in sports may have contributed.
Yes, this sounds exactly like the plot in Sid Davis' "What Makes Sammy Speed?" (1957). But it's also the story line of this film made a year later, though it involves a careless boy on a bike. It even has the same inappropriate doop-de-diddle-a clip-clop music at 5:44 as in the other short film.
The difference here is the kid's older brother is the investigator as opposed to a cop. The boy narrator reads his lines better than the monotone actor in the other film, who ignores punctuation in his copy.
In this case the kid lives, unlike the speeding Sammy, who morphed into Tom Robinson in a later Davis cartoon, "Wild at the Wheel." One story, three films.

Actually the bicycle clowns name is Jimmy. And believe it or not, I am the Bicycle Clown. Made the movie 56 years ago......
Let me know if you want my autograph... LOL

Probably did a decent job at the time.

As other reviewer notes, it's mainly worth seeing to see 1950s cars, fashions, etc.

Bicycle safety short subject about Jimmy the jerk who clowns around on his bike. Worth watching for the fifties fashions, automobiles, and the cool Schwinn bike shop. You just know that obnoxious Jimmy is going to get nailed by a car, and he does. He lives, and his brother the enabler will take care of him, and everybody will live happily ever after.

When Jimmy gets hurt after running into a car on a bike, his brother seeks answers about why Jimmy acted like this and starts interrogating every person that knew Jimmy about his bike habits, from his school teachers to the guy who runs the bike store. It¡¯s interesting though, that he doesn¡¯t go to the first place you would think of, and that¡¯s his home and their parents. Actually, they aren¡¯t mentioned at all during this piece, which made me think that they were a bunch of no good street punks in the hard hitting town of Gledonra, California.

PS, no clowns to speak of here. Which is too bad. When I heard this title, I was expecting a mix of the Bike Monkey film One Got Fat with If Mirrors Could Speak : Self-Image Film with the clowns and the mirror and what have you. Guess not.

A boy poorly narrates the story of his younger brother Jimmy, a kid who clowns around on his bike in order to impress his peers and thinks safety rules are for sissies. Since this is a Sid Davis film, he is punished for this by getting into an accident which results in him getting gauze wrapped around his head, his arm in a sling, and being confined to a hospital bed. JimmyÃÂs brother becomes obsessed with finding out why this happened, even though itÃÂs obvious from the beginning that Jimmy is an idiotic daredevil. This is one of the tamer Sid Davis films, though.
