The owners found that very young child couldn't keep up with the pedals beyond walking pace, got bored, fell aspleep and fell off.

Funnily enough that is exactly the reason I have been reluctant to use the one that we were given (although I didn't know that actually has happened...thanks for the info John). I always let my oldest son ride as long as he can and when he gets tired I simply ride one handed and push him along with me.

Just let him ride close by for as long as he can and you cankeep an eye onhis progress!

I used this method with my son and by the age of five he completed the 11mile half loop of ladybower with only two dabs!

Yer, I got bit wrong, that is why I am always learning....

 Any way thanks for the info, seems I might steer clear of the towbar idea
