Cycling, a sport with a rich history, is experiencing rapid growth in popularity (Braeckevelt, 2019). It is known for its numerous health benefits, including reducing cardiovascular risks and obesity (Oja et al., 2011).

Despite being perceived as a low-impact activity, research conducted by Delft University of Technology reveals that over one-third of cyclists suffer from saddle sores (Groenendijk et al., 1992). This prevalence is even higher among sport-cyclers, with complaints often focusing on discomfort around the perineum and sit-bones, potentially hindering participation in the sport (Napier & Heron, 2022).

Throughout this research, it became apparent that achieving a comfortable saddle experience hinges on two crucial factors: a saddle design selected to fit the purpose (cyclist’s anatomy, cycling posture, and personal preferences) and a proper bike fit. Despite their significance, these aspects are frequently disregarded during the saddle purchasing process. As a result, cyclists may find themselves cycling through multiple saddles before discovering the right fit or resorting to costly professional bike fitting services.

In response to these findings, this thesis proposes the development of a bicycle saddle with a variable side profile. This way, the rider can adjust the saddle to align it with the pelvic bone. Therefore creating an optimal pressure distribution, leading to less saddle sores. This has been done by introducing a hinging frontal and rear part, covered by a specially designed padding that makes sure that a smooth profile is established. Additionally, bike and saddle fitting items and a simple guide are provided to the customer and should help find a better bike fit at home.
