Just wondering what kind of miles your kids are racking up. Got up at 7:00am today and rode with my buddy and his daughter to a restaurant way out in the country to get breakfast. 13 miles there, stay an hour, then 13 miles back. Took us about an hour and a half each way. I thought that was pretty good for a 9 year old girl. Didn't complain or wander all over the road. She was on a full suspension NEXT bike too, so she was probably working twice as hard as us. She wants to do it again next week! We are starting to put the feelers out in search of a better bike for her, since she seems like she would be committed to it. She's on a swim team too, so if we can just get her to start running she's a shoe-in for triathalon.
