There I fixed it for you :)

Edit: An electric motor may work, just what kind of electric motor are we talking about here. As for the PVC, I'm afraid it just won't work... not enough structural integrity.

Double Edit: Just for future reference, try to come up with title's that describe what you want to talk to us about. Instead of "what do you think" come up with something like "electric scooter" or whatever you are trying to build. I know it may seem like more people will read it if you phrase the subject like you are asking a question, but many people will just ignore it. :D

well if you want one that you can have guarantee it will work buy it from northerntool.com i think there like $20, i bought one for a go kart a while back. if your gonna go with the junk yard approach just make sure its not seized up and its not covered in rust . you should find them on thing with small gas engines (in the 3 to 20 hp range)

Use conduit or iron pipe for the frame. Or like I did with my scooter I built, use a hammock frame. If you don't have a welder, then just convert a kick scooter to a motorized one.

As for the gear ratio, it depends on the size motor, wheels, where you plan to ride it, etc.

If that doesn't work, just search for tziscooterworld and it should come up on Google. The site has tons of scooters and you should be able to figure out what you are doing.
I'm weird, I know it, you don't need to tell me.

and for adjustable speeds some rotilliors (sp?) they dont i dont think... im move of a dirtbike guy so i cant tell you rotioloir(sp? again) parts and stuff but if you get like a briggs and stratton i can most likely help you. my best bet on a good reliable engine with gears is an old (running) xr or z50 engine. they are reliable and have gears which gives you speed and power. they are 3 speed.

i think i will go to the junk yard and look for at least a 3.5hp briggs and stratton motor. what size of tubing do you think is suitable for this design?

Kind of off-topic, but I was thinking, you could probably use small (3/4" or so) sch80 PVC (which is already pretty stiff) for the frame, if you filled the pipes with something rigid, like super-lightweight concrete or even bondo (though bondo would probably be expensive for this application). Weight will be the concern here.

It can be done with an electric motor, I'm sure, but finding the right motor and battery setup will be a challenge.
A chainsaw/weedeater motor would probably be a lot easier.

The gearing and interface between the motor and the back wheel(s) will be the design challenge for you. Consider finding a scrapped dirtbike/gas minibike/small ATV/etc... to steal parts from.

Good luck!

Peace,
Pete Zaria.

As long as its a horizontal shaft engine then you should be good. I would reccomend steel or aluminum tubing for the frame.
