we bought a Strider bike for my son when he turned 2. We LOVED it! lightweight, small and adjustable.
Since my son has gone on to a pedal bike his Strider has since gone on to teach at least 3 other kiddos to balance and ride pedal bikes.
when this one is big enough to fit the strider we'll either get him his own or we'll use his brother's. :)
i highly recommend them to everyone over training wheels
