The Bike Seat Problem

About two out of three men experience problems when using a traditional bicycle seat. Mostly limited and passing. But one out of ten face so severe problems that bicycle riding is almost impossible. The problems can be described in three words: shrinking, numbness and erectile dysfunction.

Also, men who have had prostate or similar surgery might not be able to use a traditional seat at all.

The Cause

Sitting on a traditional bicycle saddle causes an unfortunate pressure on soft parts of the groin. Those parts are obviously not suitable for sitting, the pressure should instead be on the sit bones in the pelvis. Vital artery blood flow is actually reduced by about 75% when using a traditional saddle. Using special saddles with cutouts, extra soft filling or special gel filling reduces this effect a bit, but not enough. There is often a 50% reduction in blood flow anyway. Besides, there are nerves in the same region, also sensitive to pressure.

Medical research reports have described these impacts for decades, they are valid for all men. The consequences are, however, very different. Most men have small inconveniences that disappear after a while, a certain group of men have considerable problems that disappear within hours, and a small group have severe and persistent problems. Research has also shown long-term impact on erectile dysfunction.

The Solution

The solution is a seat without the nose. Unfortunately such a seat is quite uncomfortable and inefficient to pedal from. The nose is the problem. That is why seats with cutouts or gel do not work. The cyclist inadvertently slides towards the nose and the problem returns. There has to be a compromise.

We have spent years experimenting with different designs and we think we found the optimum compromise: a seat with a short nose to keep you positioned but not causing pressure, and left and right halves that move independent of each other.

The halves move just a bit to compensate for the sitting position - not following the pedaling as you might think. When pedaling uphill you lean forwards and when running downhill you sit more upright. An important part of the design is also that the seat is mounted with a slight forward angle. By following the sitting position the move counteracts sliding forward when sitting upright. Another feature is that the padding is a bit thicker right where your sit bones are, which makes it easier to stay in place. The bottom line is that you sit on a flat surface, not causing pressure on the wrong zones - no shrinking, numbness or erectile dysfunction.
