Razor scooter w/ Weedwhacker

[bman]

I recently heard of a guy who mounted a weedwhacker engine on a razor kick scooter. I want to build one, figuring it would be a good place to start working with engines and things, as opposed to spending hundreds of dollars on a go kart. Any ideas on how to mount the engine? I don't really have much experiance/tools needed for heavy amounts of fabrication. Any help is greatly appreciated.

NOTE: I have the scooter, but need to find a engine to use.

what's the back tire look like on that?

[bman]

It's just a rollerblade-type wheel suspended by forks of aluminum that come out the main part of the scooter. You, know, the ones with a foot brake above them. . .

Hmm, that description sucks, lemme see if I can figure out hoe to attach a picture.

Yup, sorry, can't find a good picture anyway. The scooter is like any of the original push scooter that fold up. I might be able to take a picture later, but I don't know.

A good link for what I plan on doing, sort of. You get the idea.

looks cool, i think i'd like to build one of those, too. i didn't read all of Aaron's write-up, but it seems like when you lean you'd scrape the assembly?

I don't know, but I'm really starting to think this project isn't going to be worth it. I'll still do it if I find a decent engine, but I have no idea how I'm gonna mount it and still be able to stand. I don't think I would want to buy an engine for it...

EDIT- The guy who I originally got the idea still hasn't responded yet. Maybe tomorrow...

[robertdjung]

talking about aaron cake? if so, he doesn't respond to most "how do i do this" kind of questions. he's a smart dude, but he just doesn't have the time anymore is what he told me.

you could do a friction drive scooter. Ive seen many that work. theres a website that i looked at a while ago that had alot of pics and stuff but i can find it :(. The only prblem you might encounter is the aluminum. But you could always bolt instead of weld

My friend and I built one of these last summer. We used an old two stroke weed whacker engine. It is mounted to the scooter on a hinge like deal and uses friction drive to move it. Here is a picture of it.

Here are a few more pics.

i think that you should go with a scooter, simple but modify onw with pump-up small bike wheels, much much easier, on that link the chain was about 3mm of the ground?? u could even jus go with a friction drive...

[robertdjung]

totally sweet.. can you take any more up close pics and detail the workings?

[bman]

Wow. Cool. And that's almost the exact same model razor I have, even with the retarted front shocks...

I too would appreciate close ups, maybe more descriptions on how you made it? I still am not sure if I will be able to fulfil my project dreams, but I'll try if I get a motor.

Looked at the pictures closer, and I have a few questions. . .

Wouldn't you have to lean to the right when you ride, so the engine doesn't tip you over?

And what's the thing sticking straight up?

[Billabond1]

It is at my friends house right now, but I can get some close up pics soon.

As for your questions, the engine is really not that heavy, so there it does not really tip over when you are on it. The metal thing sticking up is the gas tank, we had to make our own because we could not find a good place to mount the original one.

Here goes for how it works. The engine is mounted on a pivoting arm and will let the engine move up and down. Attached to the crankshaft on the engine is a round piece of tubing. The tubing makes contact with the back wheel and that is how it is driven. To start it, you simply put weight on the pivot arm to make sure there tube on the crankshaft is making good contact with the wheel and then you just start pushing like you would on a normal scooter. After a few pushes the engine starts up and takes care of you from there. The throttle is controlled through the lever on the handle bars.

I hope that was enough description. Again, I will try and get some more closeup pics here soon.

Also, the whole project cost about $30 because we already had the engine and the scooter.

[robertdjung]

By tubing do you mean something like rubber tubing? That sounds really cool.

[kibble]

Awww, I want to make one now! LOL
Where is the fuel tank?

[GoAlterBridge]

How fast does it go? I might make one of thouse in the future since I have the motor and the scooter already. That thing looks awesome.

[Billabond1]

The tubing is actually a socket from a socket set. I can't remember what size it is, but we did the math and used a size that would get a decent amount of torque.

The fuel tank is the metal tube you can see sticking straight up by the engine in the pictures.

The scooter goes about 15 mph. It is not that fast, mostly due to how small the engine is (19cc i think).

Also, I am still trying to get some close up pics for you guys.

edit: Also wanted to say that the actual fabrication of it was not very hard. Everything is bolted together and we did not have to weld anything.

[bman]

Hmmm, if there is no welding, maybe I can do it, lol.
