I can see riding a 36"(first photo?), but the 39" looks like I'd need a step leader. Sheesh, and I'm 6'2". Looks like fun. What's the math with a 66cc, 40 tooth, screaming 10k rpm on a 39"? Probably we'll over 50mph? Imagine the G force on the tire at that speed lol

No you must use roach mathematics , it should be 10000x(66÷2)x39x1.5 (1.5 for 60 minutes in an hour divided by the number of teeth on the sprocket) and divide all that by 12 inches a foot and divide that answer by 5280 feet in a mile and you get 304 mph rounded down.
