The film received mixed reviews and under-performed commercially during its release.
The New York Times stated "Teen-age ears may not split from the music or ache from the dialogue, but anybody over 20, beware: 'You're willing to sacrifice building a solid future for a bicycle race,' says the hero's mother. 'It's very self-destructive.' If only he had listened to mom – but who can blame him for preferring his bicycle?" On the website
Rotten Tomatoes,
Rad was given an approval rating of 46%, based on reviews from 13 critics. In 2013,
The Guardian writer Nick Evershed found it had the largest discrepancy between critical and audience response (which at that time was 0% based on 5 reviews, versus 91%, based on 7,165 user ratings) in the Rotten Tomatoes database, from a pool of 10,000 movies analyzed.
Metacritic gives the film a score of 24 out of 100, based on reviews from 6 critics, indicating "Generally Unfavorable" reviews. Film historian
Leonard Maltin gave the movie a "BOMB" citation—the lowest possible rating in his annual
Movie Guide—explaining, "Title is supposed to be short for
Radical...as in, 'Radical, man!' Yeah, right...and we didn't see this same plotline used to death by 1950s
hot-rod films, and also by 1970s
roller-disco epics!" The film has since gained notoriety as a
Cult film. In reporting on the film's 2020
Blu-ray release,
The A.V. Club referred to Rad as the "holy grail of ’80s cult movies" and noted its "large and loyal cult following.". On March 22 and 24, 2026, to celebrate the film's 40th anniversary, Rad played in hundreds of
AMC Theaters nationwide. In reporting on this "fifth official celebration of Rad Day," Collider called Rad "The Greatest 1980s Cult Classic Sports Movie." ==Home media==
