I have been collecting some images of hover bikes strewn about the net. Below is what I came up with. I am toying with the idea of doing a racing game, perhaps with pod racers or hover bikes. I doubt that I have the artistic talent to model a good one, so I may have to get myself one on commission. Drop me a line if you can do something like this in Wings3D at low polygon count.
