Forgot the name of that childhood mecha dvd movie.. Request for help ! :3

[Lucy_Nana]

Hello everywun ! I've been looking for one anime in particular for a few months now without ever finding it ... I used to have a dvd of that anime 7 or 8 years ago when I was a kid . It was a mecha anime movie with giant fighting robots , I remember a scene with a dude with dark hair riding a futuristic motorcycle and a blonde (? ) girl on the back through the alien countryside but with domesticated cow-looking alien animals in the meadows ..

The robots looked kinda like Seikishis or Overmans and there was an epic fight at the end in a city..

I was very young back then and I don't recall many characters or the storyline but the graphics looked very cool at the time ...

If you guys can help me find this DVd OVA thing, i'd be forever grateful !! :)

thanks a lot people!
