Biker Mice From Mars "Seasons 2 and 3" (found original English audio of animated series; 1993-1996)
Biker Mice From Mars was a syndicated cartoon series that ran from 1993 to 1996. What's interesting about this show is that it was popular enough to dubbed into over 50 countries worldwide, yet there are several episodes that are not available in English. While the series got a full DVD release in France(with no English audio unfortunately), only the first season ever got released on DVD in the U.S.(and some of the episodes on that set were edited). Part of this may be down to the fact that this series hasn't been seen aired on TV in the U.S. since the 90s(though it was aired in the U.K. as late as 2000). Some season 2 and 3 episodes can be found on Youtube, Dailymotion and Veoh in English.
