This is so great! My DS was really slow to ride a bike, since his first time out without training wheels ended with him bloodying a knee. It took him a long time to even let us take the training wheels off (his fine and gross motor skills are not great). Now he's 11 and has his first REAL big guy bike (a Redline Conquest 24 cyclocross bike). His first few rides on that were scary for him, since it is SO much less stable than his earlier bikes and it's easier to make it go really fast. But now he's a little monster on it and loves finding new challenges on his 2 wheels. Our boys are so lucky to have parents who encourage such a healthy and fun activity.
