If there's three things William Hanna and Joseph Barbera love it's talking animals, kids who solve mysteries, and talking cars. Enter cartoon #5 1974's Wheelie and the Chopper Bunch.
It's the early 70's and motorcycles are all the rage thanks to films like Easy Rider. So you get the Chopper Bunch, a ne'er-do-well gang of motorcycles ala The Wild One, as they seek to trip up our hero, Wheelie, and steal his main girl Rota Ree (oh the puns!).
Wheelie ran for 13 episodes, each containing three short story segments which made it a great show to air on a cavalcade like The Cartoon Express because you could mix in a five minute short here and there, so that's where I became familiar with it. So you've got Wheelie, the only character on the show who didnt talk, but instead communicated via horn, his girl, the Chopper Bunch compromised of Chopper (hey, voiced by Frank Welker!), Revs (voiced by Paul Winchell so it's basically a two wheeled Tigger), Hi-Riser, and Scarmbles, the littlest bike who always unsuccessfully tried to stop the bunch from getting into trouble, and then once their scheme inevitably failed, blasted the crew with his "I told you so! I told you so!" scorn. And then there was the police cars who always seemed to be around, a cruiser named Captain Tuff, and a bike named Deputy Fishtail.
One interesting tidbit, Charlton Comics ran a very short-lived comic of the cartoon in 1975 that contained the first comic work of a man named John Byrne. Apparently, after the first issue he was asked to make the series "mellower" because Hanna-Barbera execs thought it was "too scary" so Byrne quit after two issues and was sadly never heard from again. At least I don't know of anything he's done for the Big 2 since.
I honestly didn't remember the theme very well, but again, I saw it mostly on the Cartoon Express. I think Boomerang ran reruns back when it first came into existence, but he whole series is available on DVD. It's a pretty simple little show that I think even kids today would like. It's basically the same idea as the 80's Pacman cartoon. It seems cartoons really breakdown into two types, a hero and a gang of villains, or a gang of heroes and a villain. I don't know. You have to fill 22 minutes somehow. I guess there were some complaints about the show by bike enthusiasts back when it aired because they thought it negatively depicted motorcycles as "nasty", and that the show depicted bad social behavior (people didn't have Twitter back then to air their gripes and there were only a couple channels--get lives, people!) In the whole scheme of cartoons, it's pretty innocuos.
Beep beep!
