Don't despair Deva, my daughter is the same way. Always had quads/bikes around, tried to psych her up to buy her own bike. No interest. I'd have chewed my left arm off(and I'm even left handed!) to have been able to have had that opportunity as a kid. I was a teen before I bought my first dirt bike myself and kept it at a friends place where we could ride out from.
My daughter turns fourteen in two weeks. Only gotten her to get on the back of my bike once. Every now and then she'll rip the farm quad around, but mostly just if there's friends over or something. What can you do? Kids are a lot like horses, can't force em.
