Training wheels

New Design Could Transform 1st Bike Ride Mechanical/engineering-wise...cool. Parenting-wise....Meh. I've taught three of my four kids to ride so far. Falls happen - they're a good incentive to stay balanced. I've seen two/three year olds riding w/o training wheels. When I asked their parents how'd they do it, they replied simply, "We put the kid on the bike and let go." That said, this could be a Godsend for kids with balance or other disorders.
