Just got my 4yr old going on his first bike with pedals after flying about on his balance bike for a few years, I give him a push to get him started he then pedals like a madman giggling away to himself before crashing about 10-20ft and wanting to do it again and again.
Great fun, can’t wait until he properly gets the hang of it and we can go a bit further, he loved the skatepark on his balance bike so will be a while off but will be riding this one there soon as well.
