Pardon the mess, but here are three big-tire bikes side by side. Closest is a Super Bronc VT8, then Heathkit Hilltopper, then a Manco Custom (used to be a 3 wheeler).
They're all pretty big bikes and if you're a tall guy like me, you'll easily fit. All of them are projects too :laugh: if I ever get some time...
I haven't had the Hilltopper running yet. I just picked it up on Friday and I've been working overtime. Maybe this weekend? We'll see.
