A field-based approach for examining bicycle seat design effects on seat pressure and perceived stability

Bicycle Riding and Erectile Dysfunction: A Review

“…The group designed a randomized, crossover trial in bicyclists (13 women and 17 men) to investigate changes in seat pressure in both genders under three different seat conditions (standard seat, seat with a partial anterior cutout, seat with a complete anterior cutout) using nonstationary bicycles. Results showing that the mean anterior seat pressure values were statistically significantly lower for the complete cutout seat than for the partial cutout and standard seat were gender-independent [43]. These findings support the seat pressure responses measured under stationary bicycling conditions.…”

Bicycle Riding and the Bedroom: Can Riding a Bicycle Cause Erectile Dysfunction?

“…34,38 A noseless saddle has indeed been associated with a greater amount of pressure converted to the hands, and could therefore lead to an increased risk for hand and wrist problems (eg, "handlebar palsy"). Current literature however is contradicting and Schrader et al 39 states that there is insufficient evidence to conclude on this subject.Lowe et al 36 notices correctly that in the study by Bressel et al, 34 the perception of stability cannot be reliable because the new saddle had only been used for 8 minutes. He states that cyclists can successfully adapt to the new saddle if they are motivated.…”

“…31,32 Concerning the role of a perineal hole, it has been shown that a central cut-out did not lessen perineal pressure but, on the contrary, could increase it. 16,[33][34][35] Sommer et al 32 attributes this to the fact that the positioning of the hole might not be well understood by manufacturers. Indeed, improper placement of the cut-out Saddle size (wide 5 narrow) A wide enough saddle that supports the ischial tuberosities results in less perineal compression Saddle geometry (nose 5 partial cut-out 5 complete cut-out)…”

Applying riding-posture optimization on bicycle frame design

“…Later, Diefenthaeler et al (2008) performed a riding assessment study on midsagittal trunk kinematics, which has had milestone significance in the anatomy of the lowest ribs, and is now used to calculate the tilt angle of the trunk, the bent angle of the spine and tilt angle of the lumbar. Bressel et al (2009) focused on exploring the influences of various bike saddle designs on saddle pressure and stability perception, and showed that these two factors are negatively correlated.…”
