We bought mason a strider bike! They are kids training bikes that don't have training wheels. They learn to run pick up their feet and glide while they keep balance. Then they just transition straight to the two wheelers. Mason has had an obsession with bikes for a couple of months now and when my co-worker said her family shop (rolling hills bikes) sells them and that her son loved his we were sold! He also got the cutest lion helmet! Mason walks around with it now saying "bike bike bike". He is growing up so fast!
