3: bevel gear meshes with another bevel gear, turning the rotation along the vertical axis to the horizontal axis
4: This second bevel gear powers a chain drive which goes down the interior of the module directly to the wheel.
I realize how easy it is to keep tension on the 1st step, what I am worried about is in the 4th step, especially if you are using #25 chain. With #35, you don't have near as big of problem, but there's still a problem.
Nice work though.

Is there any reason to use chain in the 4th step instead of two spur gears? Seems like gears might be more reliable option to connect two shafts that are so close together. But, I've never built a crab drive system.
