Exercise bike

Abstract

An exercise bike for users to exercise in a face-upward manner comprises a pedal section, a connecting tube and a base section. The pedal section locates at the highest point of the exercise bike and has a counting stopwatch and two pedals that can be adjusted to change the resistance of stamping. The base can be placed on a plane and has a pad for lying down and two flexible handles. The connecting tube locates between and connects the pedal section and the base section. Some fasteners are installed on the connecting tube to fasten the connecting tube for fixing the pedal section. When opening the fasteners, the connecting tube and the pedal section can be folded to a small unit for storage to conserve the space.

What is claimed is:  
     
         1 . A exercise bike comprising a pedal section, a connecting tube, and a base section, wherein: 
 the pedal section includes a wheel seat, a free wheel within the wheel seat, a housing surrounding and covering the wheel seat, a wheel axle piercing through the housing, wheel seat and free wheel; each end of the wheel axle having a rotating arm and a pedal with which users can stamp the pedal with their feet to drive the free wheel rotating; a brake plate and a adjusting button is installed on the upper part of the wheel seat; rotating the adjusting button to push the brake plate downward to touch the free wheel and change the resistance of stamping the pedal; a stopwatch is installed at the front of the housing to sensor the rotation of the free wheel and showing the time, distance and other data of the stamping;    the connecting tube has a horizontal tube fixed on the tube body with a bolt and a press board fixed on the connecting tube at the bottom of the horizontal tube with a bolt; an arc cover is installed on the upper part of the press board and pressing a frame fastener so that the frame fastener can rotate around the arc axis of the arc cover as its axis; a screwing button is installed in the middle at the end of the frame fastener and screwing on the second U-shape base of the base section to position the connecting tube; the upper part of the connecting tube is integrated and connected to the pedal section and the lower part of the connecting tube being installed with a pivot on the positioning tube of the base section; and    the base section is place on a plane and has a set of parallel base tubes with a first U-shape tube at the front and a positioning tube in the middle; a second U-shape tube is installed between the first U-shape tube and the positioning tube; a fixed plate is installed in the middle of the bottom of the second U-shape tube and has a threaded opening for the screwing button to screw through; a U-shape trough is designed in the middle at the rear end of the second U-shape tube with a backward opening to accommodate the above-mentioned connecting tube; a U-shape through is designed in the middle of the positioning tube with a forward opening to accommodate the pivot at the lower part of the connecting tube; the rear part of the base tube is designed as two detachable sets with two pads being placed on the rear part of the base tube for users to lie down; each one spring and handle connected with a connecting ring is installed on each side of the base tube respectively as an auxiliary device for users to hold with hands.    
     
     
         2 . The exercise bike as claimed in  claim 1 , wherein the sectional shape of the tube members of the exercise bike is flat and round, elongated round, square, rectangular and the combination of said shapes.
