The Polisport Child Bike Seat Rear sits very sturdy on the back of a bike. It is easy to put on and take off, just needing an allen key. A wrench is needed to move the seat further back as your child grows. There are instruction videos on youtube with full details on how to do this quickly. The bike does not need a rear rack as it does not use this. It's had good use but still functions perfectly.
