Abstract: The subject matter discloses a bicycle device capable of functioning as an upright bicycle and a recumbent bicycle using one seat. The bicycle device according may comprise a seat, a body, a wheel operated by the user of the exercising device and a directing rod connecting the body and the seat. Such that movement of the directing rod allows positioning the seat in front position used for upright bicycle and rear position used for recumbent bicycle.

Abstract: A multimode exercise device, including: a chassis with two opposing elongated sides; an exercise mechanism mounted onto the chassis comprising on each side of the chassis: a slidable assembly that is configured to move backward and forward along one elongated side of the chassis; a rotatable wheel configured to rotate about an axis at its center and mounted onto the slidable assembly; a pedal coupled to the rotatable wheel configured to rotate the rotatable wheel; a restraining rod that is rotatably coupled to a side of the chassis on a first end and rotatably coupled to the rotatable wheel at one of a plurality of user selectable attachment positions on the second end; a synchronizing mechanism to synchronize between the rotations of the rotatable wheels on both sides of the chassis.

Abstract: The subject matter discloses an exercising device enabled to switch between elliptical course and circular course of footrests used by a user, comprising two main wheels, each connected to a different footrest; two connecting rods, the distal end of each connecting rod is connected to each main wheel and the proximal end of each connecting rod is connected to the body of the exercising device, said connecting rods are enabled to move the two main wheels on a horizontal axis.
