Hand-crank ride?

[Yoshilime M.R.]

I was wondering if anyone knows if there is a 4 wheeled device that is powered by pulling back and forth on a long metel pole to propel ones self. If so, does anyone know what things would be involved in making it, and what it would basically look like, or a schematic or sorts?

so do you mean oull and push the pole, or just pull?
You could make something similar to a rowing machine if it was just pull, pull and push I'd imagine it would me some kind of crank/rotating mechanism incorporated in a bike styled mechanism.

also, what is this for?

 

[Yoshilime M.R.]

Its just for fun, and the fun of building.

And yes, just pull, then it will go back by it self, then i would pull, repeat etc. So a rowing machine huh? Any schematics of that?

Fail. This is not what i asked for.

It does EXACTLY what you asked for, it just does it differently.

Double post, LOL

No, i dont want to crank a ride by peddling with my hands. I want to pull a pole back, let it go forward by itself, let me crank it back again etc to propel myself.

Thanks, but not what im looking for.

Well, this isn't 4-wheeled, but this seems like the most practical rowing bike i've seen.

Personally, I can't quite make out the mechanism. Having said that, I've only been on the website for a couple of minutes. It wouldn't be hard' really.

Dang, I know what you are talking about, but I forget the name of it. -_-

This reminds me of that thing they had on railroads where one person pushes down, and the other pulls up, and you do that a bunch of times and you move along the track.

 

[Yoshilime M.R.]

Exactly, but with one crank you pull back, liek on the side. I hope its easy to build, it looks fun in my mind.

That is what they are called. I went through this set of books I have with tons of stories about old people's childhoods, I knew I had seen a picture of something just like you described.

They appear to be pretty obscure on the internets.

 

[Yoshilime M.R.]

Aww D:

Well, a mechanic for it would probably be complex i assume. I guess its time to scrap the project.

 

[PalmerTech]

No, no, they can be very simple!

I mean, check this out:

And there are some really nice ones made with bicycle wheels, too.

 

[βeta]

Oh, THOSE.

Dead simple. Here's a link to something that could easily be retrofitted to do the same.

Research treadles in general.

I was thinking that too, but the link I posted looked as though the guy was traveling kinda fast.

I see, very interesting. I dont have very much experience building though, let alone anything bike related. Looks like a project for the future.
