well they get about 50-70 mpg…so ud use 1 gallon a week if u only go 50 miles……problem u will have will avoiding all the idiotic drivers in tampa:)…….cas top speed on the moped will b like 35……good luck

They usually get about 60-75 MPG. I travel about 8 miles round trip a day. So 50 miles is not out of the queston. I usually fill up about every week and a half or so.

I own 3 49cc scoots. I average about 1,000+ miles per month when the weather is nice. My 49cc 4 stroke scooter has been modified and still averages 80MPG. It can run just find on 87 octane, so it’s very cheap to operate. The 2 stroke scooters I own are faster, but they burn more fuel. I ride in small cities, towns, and in the country. I’ve never rode in a big city, but I can’t really see why it would be a problem.

A 50cc scooter won’t keep up with traffic very well. It will probably do 30mph full speed which doesn’t make it very usable.
I am not a speed freak and once in the distant past I did Venice/London (and back! 1600miles) on a tuned up 50 that did 60mph.
I would say get a 125cc. In the end you will consume less gas than a 50 as you won’t be thrashing it around so much and also it’ll be safer as you’ll get out of traffic’s way when needed.
I don’t know if you get them in the USA but over here you can get 200cc (piaggio) that use LPG/gas.
They do 360 miles a gallon and with LPG costing half the price of petrol it means they are cheap to run!
Also, they do 95mph when switched on to gas, easy cruse at 80mph.
