This is the best kid bike seat I have ever used. I've used about 5. This was the only one I paid a significant amount of money for because it was worth it.
Front mount. Seat is easily removed and the mounting bracket is very low profile so it doesn't get in your way while you're riding without the seat.
5-point harness. Handle for the little one. Adjustable feet rests. Locks to bike (comes with 2 keys).
Was only used for 5 months or so. In perfect shape. I have everything it came with.
