If you have a scooter 49cc or smaller or an electric, show us your stuff. I'll start. The green camo scooter in front is a 49cc. I have had it up to 45 but it gets unstable from there. About a guzillon miles to the gallon. The red one is an electric bike. What a blast. Only 20 MPH but will go 50 miles on a charge, and takes 4 hrs to charge it up. I hook up a wagon to this one and pull the grandkids around. The blue one in the back is my 750-4 that I am rebuilding.
