My 2 year old loved it at first sight.  Legs just long enough for him to pedal.  Started peddling immediately after watching big brother (3yrs old) ride his bike with training wheels and his urgency to ride was well rewarded.  I had trouble getting him off of it once he started.  Well built and easy to put together and arrived right on time.  I just couldn't get over how quickly he began to pedal and ride it.  Thanks Radio Flyer!
