DD got a BYK bike before Christmas - she was very keen on having one and not having a balance bike. It is about as light as you can get for a kids bike with training wheels, but she really seems to struggle to pedal it at all - she can't get herself going ever, and doesn't seem to keep going much either.

She had hip dysplasia as a baby, and I have this nagging worry that there is something wrong that is causing this. She runs, jumps etc fine, she isn't very adept at climbing though and I have always thought she is quite weak at pushing up with her legs.

I also think her legs don't look quite right on her bike, we have tried various seat heights to try improve the ability to push down to know avail.

We try to keep practicing on the bike, but there doesn't seem to be any improvement. Today went to traffic school and see all these kids rushing round on bikes - I have never seen another child seem to struggle as much with the pedals as she does.

What do you think? Has anyone else had a child who just seems unable to pedal properly.
