(54) Bicycle for exercise, particulary a spinning bicycle


(57) There is described an exercise bicycle, particularly spinning bicycle, including a bicycle frame, height adjustable handlebars, a height adjustable saddle, a flywheel, a crank bearing housing (2) which is connected to the bicycle frame and having a throughgoing crankshaft (30) which at one end is adapted for direct no-turn connection with a base part of a crank, and which at the opposite end is designed with a drive pulley (34) and a base part for a second crank, the drive pulley (34) being connected with a drive pulley on a hub section of the flywheel by means of a drive belt, where the crankshaft (30) within the drive pulley (34) is rotationally rigidly connected with a brake disk (42) surrounded by a brake chamber (2) with braking cylinders (46,48) in which braking pistons (50,52) are movably suspended in such a way that the brake pistons (50,52), by supplying brake liquid at their respective rear sides, are adapted to exert a braking pressure at opposite sides of the brake disk (42), preferably via brake shoes (54,56) with a brake lining (58,60). By means of simple measures is hereby achieved an improved exercise bicycle, in particular a spinning bicycle, that may be produced with optimal strength.
