I have an Agility 50cc 4stroke, think you would find that too weak powered. With myself and my wife on my scoot we struggled to get up hills at anything over 10mph, it was embarrassing, together we weight around 300 pounds. Its ok with just me on it at 11.5-12 stone, 30-40mph uphill and top speed of 50mph on flat ground with the mods I did. Better to go for a 2 stroke I think, kind of wish I did that now instead of buying my 4 stroke.
