    My daugher's new balance bike

    So I was thinking of buying a balance bike for my daughter then, after looking at a few, decided to make my own.
    I've never made anything like it before but there's not much to them so thought I'd give it a go.
    It's all made from aluminum. The rear swingarm is cnc machined from solid. I also made the stem.
    The forks are Fox 36 uppers with cnc machined dropouts to look like real suspension forks.
    Just need to weld the swingarm and seat tube.
    What do you guys think?

    Looks very good to me! I just bought a Specialized Hotwalk for my daughter but I like your walking bike more!

    Its freaking awesome is what I think! The only thing that I would be worried about is the weight, how much of that rear end is solid?

    Here's a pic of the underside of the swingarm. Takes a lot if the weight out.

    Cool, did you copy the dimensions/geometry from an existing bike?

    A guy I work with had an old , wooden balance bike so I basically put it on a large sheet of graph paper and jotted all the main bits (wheel centres, bar and saddle heights, head tube angles etc) and then made it to fit I to that info.

    That's an amazing looking little machine!
    Your daughter is going to love it I'd imagine.
    I don't crash, I just have slightly uncontrolled dismounts!

    I think you have an unfair advantage over most people! Looks pro.

    The fork is major cool.

    Do you mind sharing the geo and sizing info you pulled from the other bike.

    I am planning on building a balance bike for my nephew this winter.

    Thanks for the kind comments guys. I got the wheels off an old, wooden balance bike. They're a 14" front, 12 1/2" rear. Forks are modified Fox 36 uppers. The main frame is 2" diameter aluminum with a 1/16" wall section. The head tube and seat tube were CNC turned.
    I'll post some geometry tomorrow.
    Cheers
    Steve

    Verry nice Job.
    I'm also modifying a fork for my son's bike. How did you manage to hold your drop-out in place.

    The dropouts were machined to a tight tolerance of 0.002" bigger than the stanchions then fixed in place using Loctite 603 retaining compound. It's a very solid fix ...

    I work at a university and would love to show this to some coworkers.
    But I won't because of your profile pic.

    Really? Until you mentioned it, I couldn't even remember what deesta's profile pic was, hadn't even noticed it. I was actually drooling over the amount of machine work etc that went into the bike rather than the very very tiny profile pic.
    I don't crash, I just have slightly uncontrolled dismounts!

    Nice. Thanks very much for changing it. Cheers.
    More appropriate for a dad anyways.

    I think it is a wonderfull balance bike. the only problem I see here is if this is your daughter first bike, you must start save money for the future builds.
    Nice work I wish I could do the same for my grandons
    In my workshop, dirty hands is a state of mind
