Well he'#d fight on his bike at all times, that'd be the point of him being in, to bring this unique aspect to the table. I'd personally imagine him as a fast but light fighter (He's small remember :D), using bunny hops for jumps. For his general attacks I reckon he could just punch over his handlebars and maybe add in a few revs here and there for good measure. For his aerials I reckon he could do a few spins or flips.

Now his specials are where the designers could get more creative with him. I haven't played the game so bare with me when I say that we can assume a general motorcyclist fits the part of the excitebiker. For his neutral I reckon he could just kinda dash forward a little. Charging up would rev the engine before hand kinda like Pikachu's Side Special. Not sure on the side special but the down special could be leaving a mud puddle by his tyres (I've seen them in the game) and maybe his up recovery could be boosting up a ramp? I dunno. And I'm not sure on his final Smash either. Perhaps a hoard of bikers could rampage in from one side? :P
