Although the seat is comfortable, when I try to clamp the seat down to tighten it, it loosens back up. Thats what you get for using cheap nuts and bolts i guess but it is Definitely NOT worth 100$ in my opinion. Maybe if you had a better/safer way to secure the seat so it don't fall off while riding would be spectacular. Because an injury caused by a default in your product could potentially lead to a lawsuit and who wants to deal woth that.
I purchased the seat addon and love it except the seat itself is too narrow. It goes into the crack of my behind and therefore I will have to purchase another one.
I use a ratchet strap from a review I saw to make the seat more safe and secure. Otherwise it works as a seat but I secure it with a ratchet strap for an extra safety measure.
Love this scooter, fast, smooth, lots of power,cliimes hills well.
