Come on Pred answer the questions!
How old is she? Does she ride a bicycle?
My daughter is a pretty good rider but it took a LOT more work to get her hooked than it did for the boy. The boy, was hooked before he was old enough to ride, he lives for bikes.
With my daughter, we had to make sure that the weather was nice, the ride was challenging but easily doable, she got lots of praise (helpful if it's from someone besides big bro or mom or Karl) and most important SNACKS!!!!
Even when she started racing, she was off & on with that. I'd load her bike up & tell her she had to come to the races but if she didn't want to race she didn't have to. Once we got there, and she saw all the kids she'd been competing against, she was in.
That has kinda changed now that she's on the 80, she isn't as confident with it so she isn't as willing to go WFO but she will race Women's Class if I do. She will also ride trails if I ask plllleeaasse and promise snacks, pictures and pit stops to go exploring.
Praise from others helps a TON! People at the track would comment how great a rider she was and it helped keep her motivated. On her big bro's birthday ride, she led the boys on our trails for part of the ride. One of my boys friends commented to her "Wow, I never saw a girl ride like THAT!" She was beaming.
One of my friends little boys is in the same boat, after a ride with us though, and lots of praise (and snack stops), he informed his mom that it was the best ride he'd ever done and he loved riding dirtbikes.
Bring her & the boy up for next springs Kid's Ride. Lots of kids, all levels and prizes for everyone of them.
