I have a niece that is 11 years old. I wouldn't take her on the bike no matter what. But, I've taken other kids on the bike at the age of 6+ without any problem. Just like they've said before, it depends on the kid. I think that if you have to question it, the answer would have to be NO. IMHO

I have one of These. My 5 year old loved it. The skills of riding that she has learned with the harness, has made it so that she now knows how to sit, hold on etc. I usually don't use it anymore for her when I am on the wife's bike, (sissy bar) but will use it with her on mine. I take the 3 year old out with the harness still, she loves it, I don't think that a child is too young as long they understand what they need to do.

We also have protective gear that we have them wear. It is the same stuff that the Navy requires me to wear to ride: long sleeves, long pants, over the ankle shoes,DOT approved helmet, full fingured gloves, reflective at night. We got the 5 year old a pink leather jacket for her 4th birthday...They are so cute riding with us...Kindergarten on a motorcycle, she is definately the coolest kid in her class.

My best friend , who was a widower(?) , had a 4 and 6 year old when he lost his Wife. We carried those kids everywhere on our bikes. Great memories. I typically carried his daughter , the six year old , and I left him with his 4 year old rug rat boy. If you are comfortable with them , and they are smart enough to obey your leadership............
