"As a physician, aware of the long term consequence of pressure on the nerves and blood vessels in the perineum (groin area) which could include impotence in the male, I highly recommend the "BiSaddle®" bicycle seat to anyone."

Why an adjustable saddle?

The angle of the bones at the bottom of your pelvic girdle vary between 50-60° for men and between 80-90° for women.

Our pelvic bones are often asymmetrical. One side may be slightly different than the other

Small changes in surface positioning can make significant difference in comfort.

The Bycycle Inc. saddle does not put pressure on any perineal tissue.

Bisaddle® design summary:

The BiSaddle® was initially designed primarily to function as a saddle for long distance road or exercise bike riders, but can and has been used successfully for all sorts of riding. The latest BiSaddle® construction uses thicker outer elastomer or foam surface materials which are more comfortable.

The saddle is designed to support riders only on the bottom of their pelvic girdle and not put pressure on any soft tissue (perineum). The saddle consists of two individually adjustable surfaces that have two points of adjustment each (front and back, thus lots of adjustability). These surfaces are contoured to fit the curvature of the bottom bones of the pelvic girdle (Ischiopubic rami and Ischial Tuberosities to be exact.). These surfaces are mounted on a frame that allows the surfaces to be positioned to allow for both separation and angular variations.

This design addresses erectile dysfunction in men by allowing for up to 3/4 inch of separation of the surfaces in the front, which is where the dorsal artery passes under the pubic symphasis (bottom of the V) and into the genitals. By only supporting riders on the bones at the bottom of the pelvic girdle it also eliminates pressure on the perineum. The perineum is where the prostate is for men and where all of women's genitalia resides.

saddle surface measurementsThe design also eliminates the pressure that the standard saddle horn puts on nerves, arteries & veins that run along the sides of the ischiopubic rami (legs of the V).

The adjustability of the surfaces was initially thought to allow riders to position the surfaces directly underneath their unique pelvic architecture. Subsequent experience has shown that positioning of the surfaces must also take into account individual variations in where nerves, veins and arteries exist.

The latest version of the BiSaddle® includes optional height shims for the surfaces to accomodate potential pelvic variations.

Surface material:

Visco-elastic elastomer OUT OF STOCK

The top of the surfaces of the elastomer BiSaddle® is a cast visco-elastic elastomer which is a composite polymer that is best described as deformable but non-compressible. This gives it shock absorption capabilities that are better than other substances.

Since this is a cast elastomer, unlike the gel in other saddles, it doesn't migrate over time.

Visco-elastic elastomer is also used used for inner soles of shoes, as saddle pads for horses, and in prosthetic padding.

Visco-elastic foam

The new outer material is a "visco-elastic foam" as compared to the "visco-elastic elastomer" on our regular BiSaddle®. The foam surfaces have the same contours as the elastomer except for the back lip being lower, they provide a more consistent softness than the elastomer ones, are lighter by 35% and a little less "springy" than the elastomer. Our police and randonneuer customer's asked for this softness and the smaller raised lip in the back....the weight loss is an added benefit.

The foam surfaces are being hand crafted by stacking 5, 6 or 7 layers of different softness foam, shaping that block to our surface design contours, then applying a 1/32" outer foam layer and finally putting on our 4-way stretch covering. Because making them is so labor intensive, the foam surfaces are more expensive than the elastomer surfaces.

Visco-elastic foam is also used for inner soles of shoes.

How is the BiSaddle adjustable?

individually adjustable front and back front adjustment
Each surface is individually adjustable in both the front and the back. Above is the saddle frame before the surfaces are mounted. The front of each saddle surface is adjustable within a 5/8 inch long slot. This means that the front of the surfaces can be positioned to anywhere between touching and 3/4 inch apart.
back adjustment minimum back adjustment maximum
Given a front pivot position, the back of each surface can be adjusted along a rotational plane. The range of rotation for each surface is about 25 degrees. The pictures above show the surfaces toward the inside and outside ranges of rotation.

The same frame and surface pieces are used for both men and women.
The combination of variations provided by the slots in the front and rotational adjustment in the back provides riders with a wide spectrum of settings from which to find the position that is most comfortable for riders and their riding style.
