They make x19's in full auto aswell but you may wanna opt for semi-auto 4 speed........one thing thats good about having two bikes the same is the parts are interchangeable on most things and youll only need to know one bike basically............
The x22 isnt the greatest bike with aftermarket or replacement parts either...Theres really a super thin selection of parts...........
If you love your g/f then get her a slightly better quality chinese bike and dont trust her safety to crappy-crap.....No matter how badly my girl wanted to ride my X22's I simply wouldnt allow it and gave her the X-15 street cruiser to ride everytime she asked.Shes no stranger to bikes and has a sister who had X15 full manual shift bike she used to ride..She cruises with me as much as she can when I take out some of my streetlegal dirtbikes...Good Luck
Even scooters like these are pretty peppy and girls like to ride em..............This ones 150cc and simply a twist n go model...street legal and easy to insure too......
