Close, but no cigar x2. What I'm thinking is almost exactly like the pic of my daughters trike. Except with the engine mounted in the front hooked to the front wheel, front wheel drive, and the turning wheels the back hooked to levers like hers. Maybe a 3 or 4" square tube about 1/4" thick for the body. Or if I have any left over from my current build maybe 3 pieces of this 1.5" square 14 gage tube welded side by side for the frame. More sitting almost right on the ground, legs stretched out, almost laying down...of course put a headache bar behind the seat for safety though lol. Hmmmm. Would be interesting to say the least.
I was doing 360s on hers, but the front wheel was basically making a 6" circle. It was fun until I almost flipped, but I blame that on my big but on a little bike lol.
Now that I think about it, if I can make one small enough, and find very small u joints I could mount the engine in back, and run a drive shaft up through the single tube/frame to the front wheel. More complex, but more visability without the engine in the way.
