Hi Dave
Not much that can do be done with a chain driven scoot performance wise
I had a geely chain drive and she was painfully slow

They would make nice scoots for riding around retirement communities or on campus but for travel on main roads and around town i would say they have no chance of keeping up with normal speed limits
Take care and ride safely
Yours Hank
