Bike seat for small child (Levenshulme M19)

This seat mounts to a rear luggage rack and then there's a little handle bar that clamps to your seat post. Its a pretty basic bit of kit but was a good way to transport my daughter short distances when she was maybe 3-5 years old. You need to be confident that they'll hold on and that they'll keep their feet out of the way of the wheels and chain, because their legs will just be dangling either side of the rear wheel. Also worth bearing in mind that you want the top of your rack to be pretty horizontal for this to work easily.
