Your never to old to ride a kids bike. I bought this for my wife mainly and my kids to grow into it after they grow out of the 12.5 and 16. but you know im going to ride the crap out of it when im not riding my big boy bikes, cant ride those in the basement.... : )
On a side note I just got off the phone with oset. They acknowledge a week point in the older models and said people just weld them on and never look back. They also acknowledged my batteries are shot. I just was not sure what to expect. The rep said he was 300lbs and rides a 24 almost daily and has no issues with the new style welded pegs.
