Don't get an e-bike. You are 17: It's either a bicycle or a proper engine. If a scooter I would strongly recommend getting 150cc. They are as easy to ride as 50cc but can go on 80kmh highways very comfortably. (They can go on freeways but can't get out of trouble's path very easily so best avoided.) The best value, not cheapest, would be a Taiwanese model. Italian makes charge for the name. Try Fada Scoters in Ken. Mkt. for advice. Not Motoretta. And a training course would be good. Scooter's are just automatic motorcycles so can also be hazardous to the untrained.
