Now at this point you will need a v-belt. I think I used one around 54" long, I really am not sure, now. Remember you have a little play with the le...
I built a gas powered inverted push scooter using a chainsaw for a motor, two customized pulleys, and v-belt. I later added patios instead of the foot pegs and an aluminum cover for the rear end. It worked great and my son would go about thiry miles an hour, and me being almost three times his weight went about 10-15 mph. I made a few changes to make things work and will try to list all the changes as it has been a couple years past, and I no longer have it.
I later added patios to stand on because the foot pegs were a bit uncomfortable after awhile. Then I added the fairing from aluminum sheet and painted it red to match the scooter. The fairing helps protect the rider from getting anything like feet, or, shoestrings caught up into the rear wheel assembly.
Step 2: Locate and Dissect a 3-spd 24" bicycle hub
This 3-spd hub I got from an old dillapidated 24" J.C. Penney's bicycle. I think I paid five or ten bucks for it. It was all rusty and everything, all I wanted was the 3-spd hub anyway. First I cut off all the spokes off of it. Then I took off the chain sprocket by removing the split clip on the outside of the sprocket. Then I put the sprocket end of the axle into the drill press hanging down. I then turned on the drill press and used a Dremel cut-off tool, and cut off the spoke holes and lip on the bottom end. Leaving the housing flush, and even with no lip at all. This is done so that the modified hub will slide into the modified plastic wheel hub from the rear wheel of the scooter. This is discussed in the next step.
