my boy is 5 1/2, I should have had him riding sooner but todays the day he rode it all by himself after a few practice sessions with dear old dad. he has been riding his CRF fifty with training wheels since age 3. I just did'nt push the bicycle alot. I told him I was so proud of him and gave him a hi 5. he was smiling from ear to ear. we even called mom since she was at the store to tell her. my boy told her he will show her tomorrow on easter. so needless to say I am a very happy proud pop tonight, just thought I would share.
