I've been thinking about rebuilding my quad bike with MTB fat tyre wheels so it performs better off road, but yesterday I was looking at pics from a friend who's been riding around Australia on a DIY solar power assisted trike. He's just switched to a fat tyre MTB with a trailer carrying the panels. So I started redesigning the quad in my head, from scratch, to have two suspended live axles, big wheels and a bigger but lighter bin on the back (current one is rotomolded plastic and is 12kg with the lid). Then I thought I'd better see whether the ideas worked at all, so I made a Lego "sketch". (website) I've used beams to get lateral stability rather than panhard rods, because for a bicycle-based design that makes more sense. You can see where I fitted a panhard on the front, though. Live axles rather than independent suspension because I have a rigid rear axle on my current quad that I will move across, and it's easier to make the parts in my workshop. handlebars come straight up off the front axles because it's mechanically simpler than a series of linkages to bars on the main frame (my current quad does this). Total build time about an hour :) This is more me thinking out loud than a proper MOC at this stage. I just wanted to see whether the idea would work.
