    This was my first welding project. Im pretty happy with how it turned out. I used to have flipped drop outs on it which is why the seat height looks a little funny, but hopefully they will return soon.

    You have the steerage linked to the handlebar and that can't work. The front wheels would have to be fairly small and narrow and closer together. They should be underneath the platform and directly in line with the turning fulcrum.

    They make the Husky/ Mercurio cargo trikes, where the swivel is behind the cargo box like that. They are heavy, and the box is wide, and that adds to the stability.

    They make the Worksman front-loading tricyles. They are also heavy, with fairly wide wheels.

    In both cases, the swivel part is exactly vertical, so the whole thing stays flat as you steer.

    Husky recommends not to even ride their trike empty, they say it should have 150# minimum in the box.
    My Worksman trike is definitely not too stable. It can be easily tipped making sharp turns at very slow speeds. At higher speeds, the steering is "touchy", and does not give a lot of confidence. Fortunately, it is also geared low (32:22, I think), so top speed is limited to 10-12 mph.

    I think in both of the trikes shown here, the idea is workable. But you need wide wheels in front, lots of weight, especially up front, and you need to be prepared for a much tippier vehicle than a bicycle.

    Schwinn made a reverse trike where both front wheels steered with a linkage. The idea was pretty simple, see if you can hunt up photos of it.

    You would think that when both front wheels turn, they should remain parallel. In fact, when both front wheels turn, the axles of all three wheels should pass through a common point. That involves some optimization of the linkages. I don't think the Schwinn trike did that.

    I watched your "build' thread on RRB.....And I've gotta say, I've seen a lot of bikes built before, but this one is one of my ALL time favorites.

    Wagon-type steering is not necessarily bad. The implementation in both cases is flawed... in that the axles lead the steering axis. This is like trying to drive a shopping cart wheel in reverse and expecting it not to flip around. Also, the Cg is so high that with enough speed, you will still have a problem with tipping on, even if you went to Ackermann arms. Moreover, an Ackermann system would need to be really robust to deal with any weight, assuming that there will be "cargo" laid in between the front wheels. Stick with the wagon-type steering and don't go too fast.

    Schwinn 1989 tadpole trike; only 1 concept made. I bought it after Schwinn went bankrupt or they might have destroyed it. Still had all 4 Schwinn name-tags.

    That's not the one I had in mind. I saw one on Ebay a year or so back, and there was one like it in a Schwinn book at the library. Back half was a bicycle. In place of the the headtube, it had a cross piece, with a headtube on either side, and then the handlebars had a linkage that went to the fork on either side. It had a fairly small basket on front. I can't find it on the internet, though, and don't know the model name to search for it that way. It was a "production" model, although not for long, and the one on Ebay went pretty cheap, so they must not be too rare.

    Frame and crank set came from a garbage picked early 70's Schwinn Fastback that was very incomplete. New muscle car steering wheel is attached with a homemade stem. Fun around the neighborhood or at cruise night car shows.

    Edit: first time img linking, why all stretched out?

    I'm new to the forum; did a quick scan of the previous 25 pages... very impressive bikes! I don't have any photos on hand of my chop (an old mountain bike with several feet of tubing added to the front forks, banana seat, small front wheel, etc) but I wanted to mention where it started. If you're ever in the Boston area, check out SCUL! If you're too far away, scul.org has plenty of photos. I moved away several years ago, so no longer have a gang to ride with.

    I will add my bike to the list. It still needs a little tuning, but it will be a blast to ride this summer...

    I built this as an entry for RatRodBikes.com 's Space Bike Build-Off. It was actually assembled in less than 12 hours, including a last minute run to home de pot for some supplies.
