That's very cool! I thought I heard that something like that existed. The only hard part is convincing my lovely wife that I need one so I can take our son for a little spin on the bike.
So, going by your comment, I take it that's your daughter or grand daughter on the bike? How old was she when she started going for rides on the bike? Getting picked up at school on Dad's bike is just so much cooler than a school bus!
