Sorry about the wait. This link should take you there.
Wow, good stuff. I have an old bike in the garage I might chop into.
ive already started he he he.i cant wait to hurt myself in new places.
Jeff, that is way cool! Your distance is unbelievable, but that’s what practice does, I guess.
I was going to piggy back on Adam’s comment about his old bike lying around.
I have a bike that has been lying around that just needs skewers to get moving and maybe a hacksaw here and there.
Jeff, Did you use a regular seat post?
Gotta try it.
Thanks for getting the shots out there.
What’s easier to ride, the Sem or the UNIbike?
Work the maze.
awesome !!
I can see that I’m going to have to make sure my health benefits are up to date (this could hurt a lot !!).
Rod,
I couldn’t get enough forward tilt out of the rail clamp seat post. I changed to an old style that did not limit the rotation.
At this point, the Unibike is easier. Still waitin’ on that Velo. I’d like to try it on both of them. I thought I had seat problems on the Unibike, until I sat on that Viscount for a while. (oouucchh!!)
Do I have to write a disclaimer before you guys get out the hacksaws?
- Don’t try this at home! -
- The subject in the picture is not rational or sane, and accepts no liability! -
But let me know if you need help with the building process.
Does it feel like riding a unicycle? o does it feel like riding a wheelie? It seems like a wheelie to me. 
That is so cool!!!
I was also thinking of doing something similar to an old bike as a way of getting a geared Uni. My question is, if you chopped off the handlebar, the top and down tubes, and used a Unicycle seat (angled appropriately), will it ride like a unicycle? I mean, if all you had left was the rear triangle of the original bike? I suppose it will be quite difficult to mount until you get the balance right, like mounting a uni for the first time?
Forgot to add, and after reading your other post…
If the rear cluster was replaced with a single fixed gear, without the freewheel mechanism, then I would guess that it will ride more like a unicycle. You would still have three gears up front. Maybe a chain tensioner would be needed to keep the chain from flopping around on the small and middle chainrings.
then just leave the rear deraileur on.
As with others, we’re in the process of building a similar type cycle, except ours will be like Guy Hanson’s cycle that he rode in the Torchlight Parade in Seattle. So far, we’ve welded a sprocket to the rear hub so we’ll have direct drive in both directions. We’re also looking for a banana seat so we can get the center of gravity more over top of the wheel and do away with the handlebars. I suppose it’ll be a recumbent uni like I’ve seen in internet pictures. Only thing is that the gearing is wrong. We still have the large front sprocket so the thing rides more like a Coker and is hard to control. Just waiting on time to work on it. Seems the weekends are quite busy most times.

NSX,
It has kind of a unique feel; not like a uni; not like a wheelie. But if you’re thinking of building one, wheelie practice is probably better than uni practice (but NO practice until the neck is healed!). That is, wheelie practice ‘without’ a fixed hub. You need to get comfortable with trusting the brakes long before removing the front wheel. With a fixed hub, it would probably have more of a uni feel, but I haven’t tried it.
Gizmo,
If the bars were removed, I don’t know where you would mount the brakes and shifters. If either the front or rear sprockets were left shift-able, I think you would have way too much chain slack to be able to ride it without brakes. I’m sure Harper has considered this.
Unibike pics finally hit the gallery!
That’s frosty as hell, Jeff! Thanks for the pics!
Anybody who builds (cuts?) one of these (and I’m considering it as a way to get rid of my ex-fiancee’s abandoned mountain bike) should understand that they automatically waive the right to complain about “Where’s your other wheel?” queries.
