Here goes nothing.. There is this feature cartoon film that I saw 22 years ago, when I was 6, possibly from the 80's or early 90's, featuring anthropomorphic animals. Protagonist, I believe was a rabbit, he had a bike and he had a girl, maybe there was a gang of some sorts (bike gang) ... It might be even foreign( not American or English made). His girlfriend gets captured and he is in a bit of a pickle ..
I've research for a two weeks now, but google wont cooperate.. So you guys are my last hope, any idea is welcomed..
Oh. I wish I could help you more here. There is a Wikipedia page called “List of fictional rabbits and hares.” It provides an extensive list of rabbits from literature, TV, and movies. Maybe you could find something on the page that sounds familiar.
