hold the wheel axle to the bar and tighten with wrench

Step 4: The Second Front Wheel

do the same as first wheel

Step 5: Inspection

make sure that the wheel does not rub against the bar

Step 6: Test Run

after you have it done then time for a test run. when you try to turn one way the other front wheel will come off the ground, but dont worry that is all normal. thanks for watching, plz vote for me in the bike cont

    You really don't want to do this. Unless you are SuperDave.

    Because I'm an engineer? Google around for a course on engineering statics. The moment greated on the axle will be too large.

    This is great. I remember using training wheels and it was terrible, because I would wobble side-to-side. This gives stability in the front, which means better control.

    I would have to agree, one solid axle is definitely the way to go. I personally tried this project a couple years ago and found the bike very tough to steer and ride, as the tires tried to bow away from each other. I didn't observe any stress on the forks. But I saw a significant amount on the wheels. It is however, an awesome project. Great thinking with taking something that's been the same way for years and making it new and exciting. A little more development and it'll be a sweet set of wheels.

    cool idea but I think it might end in disaster......

    Interesting idea, but not really safe for anything more than a gentle ride-about.

    Without a single, solid axle, you're putting way too much twisting strain on the dropouts. So find some threaded rod of the right diameter and thread and long enough to pass through both hubs when mounted as you show. Take ALL the cones, nuts and washers off each axle and put them on your rod, remembering you've got to clamp to the dropouts as you have done.

    If you can't get any appropriate rod, drill one or two matching pairs of holes in your dropouts and connect them with whatever you can find closest, remembering to tighten on BOTH sides of each dropout, to keep them/the forks collapsing or splaying.

    The first method would be preferred because the second still allows each wheel to twist its own dropout.

    Awesome!! Please post a video if possible, it would be interesting to see the Trike in action .. Thanks

    That looks so awesome! Though like Kiteman mentioned, I would be worried about possible damage to the forks. Is there any way to replace the threaded rods running through each wheel with one giant long one? I would think that would reduce the stress on the forks.

    Are they strong enough on one bolt each?

    Is the steering not wrecked by this mod?
