Weed Eater motor Bike(Friction Drive)

This is my Weed Eater motor powered bike. It is friction drive, as you can see, and is mounted using steel. We were thinking about aluminum, but it might be to light and not strong enough. the drive shaft is on of the stunt bike pipes. The hardest part was the mounting technique, mainly because the motor hardly have any good mounting spots. Credit to my dad for helping with the mounts, and without using a welding torch! Enjoy!
yes, could you make an instructable? i would love to find out how this was attached without welding. since i cant weld.

How do you put the peg on the clutch shaft? Can you u just thread it with a tap and die? Would it work if you just mounted the clutch shaft against the wheel without the peg on it?
I thought that you were supposed to give instructions on how to make it

What size engine is it? And how does the power do with all the weight on it? Like climbing hills?

For me, that toro would be a very big engine to run on a bmx bike like the one you have... I don't know about how it is to actually ride but for a probably 25-30cc motor I think the size and weight would slow it down.. Just my opinion...

Yes, but after I modified the attachment system from being forced down to only gravity, it worked a lot better.
Yeah.. Okay I see why you mean...

hey I used a 11/16 inch socket as my drive shaft and it doesn't grip the tire well enough because its smooth. Do you think if i get a bike peg that has grooves like yours do you think it will grip better? thanks
Hackrtanman (author)  Enzomatico2 years ago
Yes, it will work alot better, but also, make sure the motor is loose and can move up and down on the wheel, so its not tight.
does the tire tread matter? because on my bike the tread is completely flat.
Hackrtanman (author)  Enzomatico2 years ago
No, but I highly recommend have some tread. Go to a bike shop and get treaded tires

does the motor always spin in the same direction?? i have a leaf blower gas motor but i dont know which side to put it on
Hackrtanman (author)  11richie212 years ago
you want it to go opposite of the way the wheel spins, in the case, your looking at it spinning clockwise
thank you once i get a welder im going to finish this project
