I saw this at the Procession of the Species Parade. Looks like it would hold the largest of clydesdale without a problem. Bouncing of the frame causes the offset wheelhub to rotate.

What is it? Is there a name of this type of two wheeled human powered contraption?

it looks like tom is riding / driving / navigating it though

It looks like his left foot is the brake.

Hoosier dirt track tires... I love it!

With that size of tires, I would upgrade the brakes from Converse to at least Nike. :D

That is... obscene, yet fascinatingly cool. How did he propel it? I see no pedals or whatnot.

looks like he pushes the tire with his foot that would get very very very annoying for me

OP said that bouncing of the frame caused an offset linkage at the rear hub to rotate the tire.

Cool, a Frankenscooter!

Ah hah I see that now thats kinda cool!!! I want one then I can go the same speed as my wife!!!! LOL glad she doesnt read this forum :P I am kidding of course her darn Navigator 2.0 goes quicker then my 4500 at half the effort.

The eccentric rear hub will mess with the steering geometry every revolution. I'd be leery taking that thing down any steep grades. :)

heres a company that makes one. They even have some videos of it in action

Except for the paint I thought it was my buddy Danno's Canondale Fatty.

Thanks Turboem1 for the link to the video. It does show the inchworm type 'gait' that thing had when he was riding it. http://i73.photobucket.com/albums/i233/static612/IMG_0227.jpg


There were several people riding these types of bikes there like this one.

Kangaroo bike!

You may not get far on the HulaBike, but you'll have fun trying.

Awesome :D
