What if...

He's got his normal bike. And then two Gouram like helper bots. One a Pteradon and the other a Plesiosaur. One helps him fight in the sky and the other helps him fight under water. The reason I figure it this way is because Paleo won't very well need his bike for aerial or aquatic combat.

But here's the gimmick: The pteradon combines with the motorcycle to become a rideable mecha T-Rex, and the Plesiosaur combines with the bike to become a Triceratops. Or vise versa; it could go either way. Basically one autonomous dino that combines with the machine to become a steed in the form of another dino entirely.

That sounds pretty kickass to me. (Not to mention, it would hypothetically make some great toys )
