    I just had my truck go out on me and I don't have the financials to fix it. So I decided I would take some of my spare bikes and a 21cc Weed Eater engine to get me some transportation till I work things out on the truck. So I would like to know if anyone had any advice, tips or even some great basic plans that work. I don't have any real machining tools so I am limited there.



    and I have just about 2 days to get this built.(c)


    Anything would really be appreciated, Thank You.

    hi; we will try, but until then, go to search. a hint you may use angle iron fron bed frames at goodwill. and for wheel maybe a skateboard. good luck-- alot of guys with pickups will give a lift if you thumb with a bike-it shows you are trying.

    Oh thank you, I may have one of my old ones skateboards around.

    I have kinda worked out the idea of building one last year but I just let the year slip by too fast. I do have a spare 6 inch lawn mower wheel but I figured that was too big.

    I'm sorry, but two days would be pushing a ground up build unless you are very imaginative.

    How about mounting the weedeater so the string head runs on the sidewall of the rear tire? Rig up a throttle mounted to the handlebars and off you go.

    ...or mount the skateboard whell to the end of the string trimmer and run that on the tire.

    I guess that could be done. I would really prefer another method.

    Yea, I saw that. I am thinking about it trying to see what I can imagine. I was thinking the easiest way to go was gonna be a Friction drive. I am just trying to see what ways I can work that out to work the best.

    Ok, I think I may of worked out my basic design. Let me know what you think.


    I will have my Engine support built with 2x4 I have cut to fit how I need, I will have some chicken fencing over the Engine to keep it from moving around....I will then run a friction Drive by attaching a bike peg I have to the Engine. I have worked out my Throttle, and Kill switch locations.....So how bad is that?

    Not sure I am understanding about the chicken wire thing, but the rest sounds good.

    You mean like a cargo net to hold the engine in place?

    I can't wait to see a picture of it. That should be a very unigue build. I did see a bike somewhere that had a prop on a weedeater and used a prop drive. Looked like a good way to get a head chopped off though...............

    A bolt and a washer? Does your shaft have a threaded hole in it?

    You Need Deacon!!! He is the man or should I say the Macgyver of motorized bicycles especially if you have a weed whacker motor, but you will need, several 1/2 filled rattle cans of paint, duct tape, some sulfur and a compass. (c) Walter F.
