    Fat Quad-cycle

    Thought you might like to see this oddity...

    custom quad cycle made by Lightfoot Cycles in Montana. Not quite finished-still needs the rear rack installed.
    It is for my sister. She was in an accident and suffered brain damage to the part of her brain that controls balance, etc. So sadly cycling was a thing of the past for her. Until now! I will of course be doing extensive sand, mud and snow testing for her. Just to make sure it is safe.

    If I ever got in such an accident, I would do this very thing. Props to her for having huge nuts (metaphorically of course), and to your for the assistance.

    So awesome!

    So, does the rear have an actual differential, or will your sister have to powerslide through corners sideways???

    how do the rear derailleurs work (I can see 2)? Both shifted with one lever/gripshift?

    Most delta trikes I've seen so far use a single casette and derailleur or IGH in the rear center which transfer powder to a central shaft either equipped with a differential or 2 freewheels (1at each wheel)

    I was going to ask something similar...but also...is that an IGH just below the seat?...it looks like one to me...so...2 RD and one IGH? if you can...please explain!

    Very cool rig. Love the 4-wheel disc brakes!

    There's no need for a differential without an axle connecting them...

    Yeah thats the idea.

    It is has a Rohloff with two R.Derailleurs working off of one shifter. The compound gearing is because she needs a very wide range of gear combination. She lives on a hilly ranch and we wanted to make sure that she did not get herself stuck. I have smome concerns, but the builder tested it (apparently they had a hard time letting it go ) and said it worked beautifully.

    That is awesome!

    What a great way for someone to whom biking was once a thing of the past to become a thing of the present and future.

    I hope your sister can get that thing away from everybody who will want to help with the extensive testing, for safety of course!

    You MUST try it on snowmobile trails. Double the float of a fatbike, but harder to push or carry......

    and get a pedal powered winch for it for really steep parts with no traction.
    Then go to the ski hill and play!

    Hey, tferris, could you post a few pics of the front disc brakes. What hubs does this quad use. And: ISO or post mount?

    I've been thinking about building something like this for a while now. I love the 4 wheel fat tires with the 4 wheel disc brakes. Excellent!
