This show is one of the best of the 70's

I have seen this cartoon many times from the time I was a little kid to now.

This show is good because you get to see a motorcycle rider doing ramp stunts and solving problems for other people. The scenes where it shows Ernie Devlin in the air when his bike is doing the jumps what looks like to others as him just going 10 Miles per hour is where they are really showing him doing his stunt in slow motion because real motorcycle stunts like that have those motorcycles going so fast that many people who are on the opposite side of the big top could not focus in time to see the rider going up the ramp. This show has him in slow motion so everyone watching can see how he does his stunts. This show should have all of it's episodes released on DVD box sets like some of the other Hanna-Barbera shows because it is a classic and much better than the shows that have been made in the last 11 to 15 years.
