Self-designed Mini-Giraffe unicycle

UNIquelyCanadian · 2005-09-05T20:45:33+00:00

Here’s a photo of my home converted bicycle/unicycle. My design requires one weld to convert a regular bike into a giraffe unicycle. The hub of the wheel is locked-out with a bead of weld. It has a 12" wheel and 3.5 inch cranks. The gearing makes it ride like a 18" wheel (if there is such a thing). The frame is a complete kid's frame with an adult front fork bolted (two bolts) on so the wheel is centered under the cranks. Again the only unicycle specific part is the seat. I've only ridden it for about half a mile. So far the design works. It We are not expert welders so the weld might not hold very long however I'll keep riding it until the weld locking the rear sprocket out lets go... I learned how to UPD well on the last project. (the joys of testing). I hope this and my 'previous project' (http://tinyurl.com/77kyn) inspires other people to try similar conversions. More photo's available upon request if anyone is interested in trying to build one. -- UNIquelyCanadian - 157 cm sidehop > ;-) There are no stupid questions, but there are a LOT of inquisitive idiots. ------------------------------------------------------------------------ UNIquelyCanadian's Profile: http://www.unicyclist.com/profile/7524 View this thread: http://www.unicyclist.com/thread/43095

That looks really good. I might try a design like that.

I wouldn't try muni-ing on it, but it's a fun design. Does the center
of gravity feel strange on it? It would make a great prop for a
parade, especially if you keep the colors the way they are.
And if you added a hinge on the crown, it would be extremely
portable...

It rode normally, it was odd with the very short cranks.
It should be said that the bearing cage was destroyed after only a few
miles of riding, a little kids bike rear wheel isn't made for a 170lb
rider. It was a cheap bike to begin with; a better quality bike should
last longer. Also, I'm not sure I reassembled the hub correctly either
so that probably didn't help the bearings.
I'd recommend the project to someone with mechanical know-how and a
spare kid’s bike. You can buy a second-hand little bike for something
like $2, the 26" front fork can be off any regular bike.

Isn't a mini giraffe kind of an oxymoron?
What exactly defines giraffe, the gears, orthe height?

Giraffe refers to chain driven, hight doesn't matter.
Correct me if I'm wrong. 🙂
