Gradually getting the hang of CAD. It doesn't look massively glamorous, but it tells me all I need to know so far.

I now know what size panels I need to cut from this, so that will be the next step. I've also discovered that the thickness of the base panel may not give enough ground clearance with the wheels that I have. They are quite hard plastic anyway, so attaching some bits of rubber tire could help give extra grip and ground clearance.
Good work. Even a very basic CAD model is really useful I find, just to see how things will roughly fit together and how big various bits need to be. I don't think I could make anything other than boxes without CAD.

Starting off with hard wheels/low ground clearance is a good bet, you can always try it out and add the bike tyre afterwards!
