“The kids’ bike is a 36 in.front wheel, the monowheel is 72 in. in diameter.
No kits for either. Just my copy of a Chinese mono wheel and totally mine for the kids bike.” Jon Jacobs, Samaria, Michigan, U.S.A.
That’s a very cool mono wheel, bike and some very fine craftsmanship. Take some video of someone riding it so we can post it for all to see.
