The Sherman Max seat is one of the most comfortable EUC seats I have had the pleasure to sit on. The latches that hold it in place will not allow the seat to be dislodged during a tumble. You can quickly remove the seat or undo the rear one and lift it for access to the screen. The seat is just wide enough in the front that it can also provide additional leverage on the wheel in quick turns. The other not about the swell and the slight width increase in the front is it allows you to use to in addition to power pads for extra pressure on the wheel while torquing the wheel. Customer service at eWheels is some of the best I have had when purchasing parts for a EUC or even a new wheel. My inquiries before the purchase of the new wheel and its accessories were answered the same day, usually within an hour. The way eWheel deals with customers has gained them a new customer. One of the keynotes about dealing with eWheels is they are personable. They do not treat you like you are just another customer. They take their time answering your questions. The team will hold a conversation with you answering questions, providing input, and helping you with any issues you may have.
