content: My mother purchased this for my daughter for Christmas. At the time she was 15 months old. She was just tall enough for the lowest setting on the seat. She quickly learned to climb on and off and go forwards and backwards and loved her bike. The steering was a little stiff and took a while for her to get the hang of it.As spring came we moved outdoors and she got better at steering. She grew so I moved the seat to the second setting. Now, at 18-20 months, the bike isn't so great -- when she tries to go forward, the back of her feet hit those rear wheels - every time! I've tried every height setting on the seat and it doesn't make a difference. She always wants to ride her bike, but gives up after just a few feet - who would want their feet to get hit all the time! The rear wheels are just a few inches too close to the seat.We will be looking for a replacement. Disappointing.
