Tandem Unicycle

The Tandem Unicycle Project


EDIT: Here are the tandem unicycle construction details for the makers out there.

EDIT: A short video of me and Jason trying to ride it: riding the tandem uni.

EDIT: For all the traffic visiting, I recommend watching the Africa Unicycle Video. It is much better!

    I wish I could take credit for the idea, but I saw it before at a mountain unicycle weekend in 2006/San Diego by “lobbylobster”.

    Is it like teetertotter when 2 people are on it?

  6. corbin says:

    Yeah, it is like a teetertotter — it is tough!

    Hi Corbin,

    Thanks for taking the time to share your creativity with a blog. A friend
    mailed me the link to your blog this AM.

    I am a fellow unicyclists, welder, machinist, builder, and blacksmith…

    And run a company making ultralight backpacking gear… So I guess I’m odd.

    Anyway, is this tandem thing at all ridable ? How do you both get on the thing ??

    I’m really wanting to get a big wheel. I ride a 24″ on the street now.

    Thanks, Russ


    Hey Corbin,
    I like it. The seats are facing in the rite direction too.

    […] a whole lot of build info, but this looks like it would be an exciting ride! [Thanks, […]

  10. Mitch says:

    That looks really hard to ride. Is the cog in the middle of that looks like it isn’t attached to anything to adjust the chain tension? Does that fall out if you hit a bump?

  11. Ray says:

    Cool. As it’s symmetrical, I guess the users could face in, face out, or face in the same direction. All you’d need do would be to cross over one of the chains. Make it even more impossible to balance!

    I used to ride a unicycle like most people ride bikes, but I would get on that thing for all the tea in China! Where are all the engineers? That contraption is an accident waiting to happen.

  15. Daniel Sorensen says:

    When can we expect to see a demonstration video. You would be the only youtube tandem unicycle sensation! I really would like to see that as a fellow uncicylist. “You actually know how to ride that?” They still ask after you tell them that is how you got to the party.

    Hi All! I posted a short video:

    I haven’t had much time to try to ride it with anyone, but it is definitely do able with some practice! Louise, my wife, is going to learn to ride it with me, and eventually we may try riding it off road.

    Bill — the unicycle is not an accident waiting to happen; it is no more dangerous than a regular unicycle, nor is it more dangerous than learning to ride a bike when a child!

    Mitch — the cog in the middle is a chain tensioner (temporary). It doesn’t work well enough. I need to make a proper one. Does it fall out? Well, not yet, but I haven’t ridden it far enough.
