As soon as Sam got rid of training wheels, Ellie wanted to lose hers too. She practiced for several hours, but didn't quite get it. She put her training wheels back on for a couple weeks, but last night was the night. She asked Jon to take them off and our neighbor walked up and down the street with her until she got it. She needs a little more practice to master the balance but I think we can safely call her a "real" bike rider.
