Found a picture of this Uni thing in a juggling site thread.
How the heck would you steer the thing?!?
Haha a “Uni-steamroller”!
i dont know, but i want one.
terry! he stole your peace sign!
Well, actually that IS me before I started using sunscreen lol!
That monster wheel unicycle reminds me of this other type of transportation. Even though it’s not a unicycle and is off-topic. I think it’s hilarious to figure out how you would ride it. 
At least you wouldn’t have leg chaffing.
Yeah its a pretty old pic. Its cool though. I would love to try one of those, just for the hell of it. I wonder what stand up wheel walking would be like on it. I think it might be posted on John’s website as well.
Thats pretty fantaastic. I’m sure the novelty would soon wear off if you owned one.
I believe that’s a Puerto Rican rider from either one of their club meetings or from a UNICON years ago.
The best I’ve been able to figure is that he works for an auto racing team. Pictures of him riding that unicycle have shown up from other auto racing events. I just have not been able to track down which team he works for.
I wonder how long you could still stand on that thing haha
Like…forever!
I think the back and forth balance on that would be very had due to the mass of the wheel. I think idling it would be very hard.
