INDOOR EXERCISE BICYCLE HAVING UPHILL AND DOWNHILL MODE

摘要

The present invention relates to an indoor exercise bike, and more particularly, to an indoor exercise bike capable of implementing an Uphill mode and a Downhill mode through a simple structure. In the indoor exercise bike having uphill and downhill mode functions according to an embodiment of the present invention, a circle on one side of the wheel is carried out by advancement of a brake mounting connected to a lead screw rotating through a motor. A brake unit controlling a pressing force applied to the main surface; And a gear unit that is spaced apart from the brake unit of the lead screw and engages with a predetermined distance, and controls a speed of the rotational force of the wheel according to the rotation of the lead screw, wherein the brake unit is operated in an uphill mode. , The gear unit may be implemented to operate in a downhill mode.
