Custom seat I just removed from ET4. It is thicker than the normal seat and has denser foam. I bought the scooter with this on it and the person said it is more comfortable for longer rides. It's too tall for me and my toes don't reach the ground. It's black and in very good condition except I think it's missing the plastic cover piece around the grocery bag hook. The hook is still there, please see picture. Will ship for cost or local pickup.
