The strider/balance bike is amazing! Our 2 older boys each used it for a summer (in addition to occasionally riding a bike with training wheels. ) Our oldest started riding a 2 wheeler without needing any help at age 4 and our middle son just transitioned to riding a 2 wheeler at 3. 5! As a pediatric physical therapist, I absolutely recommend strider bikes for teaching bike riding! It does take a little time for kids to learn to glide rather than step with it, so just encourage your kid to keep trying!
