The Nexride saddle is a noseless bicycle seat. Nose-less bike saddles have the primary advantage of not pinching the pudendal nerve during cycling. The pudendal nerve, located in the pudendal canal, passes under the lower edge of the pubic bone (shown to left).
A problem with conventional bike seats is that the front portion of the saddle (the nose) crushes that pudendal canal. See image. As you can see, cutting out the center area of a saddle just doesn't help. In fact, that cut-out may make matters worse by shifting additional pressure to the sides of the nose of the bike seat.
With the Nexride saddle, the rider's weight is supported only by the sit bones, so the pudendal nerve is unconstrained.
