Bicycle seat consisting of two from each other separated support portions for supporting one of the bicycle rider's (upper femur) seat bone, whereby each support portion is supported by a joint bar, which is arranged perpendicular to the central plane of the bicycle. In order to make the bicycle seat comfortable and specifically facilitate the movement of the seat bones when the rider pedals, it is suggested a combination including that each of the support portions is fixable on the bar and consists of at least three layers (6, 7, 8) firmly connected to each other by means of meeting surfaces, the undermost layer (6) being stiff and is fixable on the bar (3) and that the next layer (7) is a cushion, which is elastic in all directions. A third layer (8) is placed on the cushion and is stiff in all direction in its plane. The thickness of the cushion (7) is increasing in the direction to its forward edge and the elasticity is such that the surface pressure from the rider's seat bone when the thighs are moving up and down is met by the elasticity without the elasticity being completely consumed.
Bicycle seat including two separated support portions each one for supporting one of the bicycle rider's upper seat bone, the two support portions being mounted on a joint bar, which is arranged perpendicular to the central plant of the bicycle, characterized in the combination that each one of the support portions is adjustably fixable mounted on said bar and consists of at least three layers which are secured to each other by means of the meeting surfaces, undermost one of the layers being nonflexible and mounted to the bar and the layer placed upon said nonflexible layer being a cushion, which is elastic in all directions and the uppermost layer being rigid in all directions in its plane, whereby the thickness of the cushion layer is increasing in the direction towards the front edge of the support portion and the elasticity is such that the surface pressure from the rider's seat bone caused by the up and down movement of rider's legs is taken up by the cushion layer without the cushion layer loses its elasticity.
