Hi CGlaude
I agree the 16 year age recommendations doesn't make a whole lot of sense. My two sons ride all the time. Douglas (16) and Ben (11) and myself usually glide together although Douglas often glides solo. We all started gliding last year when the Segway tour guide in Oahu (at the fabulous Hilton Hawaiian Village) allowed both boys to glide at ages 10 & 15 even though their policy is 16 and older. We had a great time and even took a private tour the following day. Wound up buying 3 Segways from Norris at Segway of Sacramento a week after we got back.
Glide safely and courteously and you'll have lots of fun.
