That is very cool! How did you make it?

i am totally interested in this mostly since i have been chatting
recently with a bike mechanic i know that builds recuments out of old
ladies bikes requiring little to no welding.

i have a few donor bikes laying around im sure one could stand to be
converted to a mini giraffe. please do share!

Nice job! How did you disengage the freewheel hub? Is it difficult to
keep the chain enough tensioned?

Yeah, some more pics would be good.

Here is a closeup photo of the drive system...

I laced the standard bicycle rear cogs to the spokes with twisted wire
strand; this effectively locked-out the gears, with minimal slop.

The tension on the chain is similar to an old BMX-style chain...there
are no tensioners...I just shortened the chain, pulled it tight using
the tire, and then tightened the rear axle.

There is a very slight amount of slop (1/30th of a rev) while
pedalling...

BTW, the duct-tape is only to protect from sharp edges...it isn't
actually holding the frame together!!! :p

What is the duct tape covering up? It looks like hose clamps or
something similar.

If you have hose clamps holding it together, and wire holding the bottom
cog in place, I would consider your giraffe a "temporary" vehicle.
You'll need something more robust for it to last any good length of
time...

what is that white tubing? awsome uni man. I was thinking if building
somthing like that but leaveing the bike in tact so it would look like
some one was riding a vertical bike. have a seat post comming out of the
handle bars its called a bunicycle.

awsome

Drink copious amounts of alcohol then go for a ride. UPD almost

I actually find it easier to ride the uni than to walk after copious
amounts of alcohol 😄

... anyhow, that's a pretty sweet machine there dude. I have an old
trash bike that's now looking like it might be fun to convert 😄

And my friends just upgraded their seats, so I could probably nab
theirs. project time!

Cool uni! You should design those and sell them for like $500 a pop!

I love your idea. When I find a 20" bmx bike in the trash I will use
your idea with 2 changes.I will cut the downtube about a foot above the
bottom bracket(pedals),fill it with sand and heat it at the bb and bend
the tube down in line with the chainstays.At this point it should look
like a regular giraffe uni.If you take the face off a bmx freewheel and
fill it with epoxy,solder, or melted lead it will no longer freewheel.I
still may have to orient the frame correctly so the fw does not screw
off on its treads.Turning the bike backwards to keep the fw on may cause
the pedals to unscrew however. I will post again after I put something
together.

If the pedals unscrew, swap the cranks over.

Cheech: Both your additions sound great! To make it look like a regular
giraffe uni will you have to weld the bent tubing back to onto the frame
near to the bb or use bolts? The reason my proto is as simple as
possible is that I don't have access to any welding equipment. I saw a
design on the internet to lock out a hub where the guy simply welded two
beads right where the cogs met the axle on the outside. Maybe it would
be less work to do that rather then going into the inside?

kington99: you've been riding a direct drive unicycle too long.🙂 a b*ke
has a chain with a chain ring on the right crank. If you swapped the
cranks you would have to reverse the tire as well; that would put allot
of strain on the lockout on the lower cogs.

Damn, yes you're right, for some reason i had the image of a non-giraffe
unicycle in my head, even though i've been riding exclusively giraffe
these last few weeks, also i thought that the sprocket was on the axle,
not the crank, but a quick check has confirmed i'm wrong again. In that
case, locktite those pedals!

My addition to your idea requires no welding. The downtube when heated
and bent in line with the chainstays(now forks) becomes the seat tube! I
guess both sprockets will have to remain on the right side as someone
noted.
