I am no fan of tall bikes but if that’s your thing, have fun.
This thing however is just bat whack crazy. I would love to see someone try to ride this. Though I bet it does hella wheelies. With that donut of a front wheel wheelies might be the safest approach.
You’d also have to be on the lighter side or that seat post will snap in two over the first bump.
All that said, while I doubt it’s usable as a bike, it’s a really cool work of art. Sort of an abstract bike. Something out of Dr. Suess maybe.
