my son has taken off his training wheels... I got him a new bike for his 5th birthday last week and it has them... so I took them off the one he has just grown out of and have been sending him out on it for practice... he loves it! I was nervous as he is a bit of a speed demon, but he took to it right away. other than when he stops, he hasn't fallen yet.... he was always good on those balance bikes when he was younger, so I guess it's not much of a surprise.
guess I can take the trainers off his new bike now! they grow up so fast...
