Abstract

A pedal bicycle comprises a bicycle rack, a front wheel and a front wheel axle, a rear wheel and a rear wheel axle, a braking device, a direction lever and a handlebar, and is characterized in that the bicycle rack is coupled with the front wheel axle on two sides of the front wheel; flywheels are coupled onto two sides of the bicycle rack coupled with the front wheel axle respectively; levers are coupled onto two sides of the bicycle rack respectively; a pedal is arranged at one end of each lever; an arc-shaped gear rack taking the axis that the lever and the bicycle rack are coupled as the central point is arranged at the other end of the lever; the arc-shaped gear rack is meshed with the flywheels arranged on two sides of the bicycle rack; a reset device is arranged on the lever; the rear wheel is arranged at the tail end of the bicycle rack; a steering device is arranged on the rear wheel axle; the steering device is connected with a direction rod and controlled by the handlebar. In this way, a pedal bicycle rider can simulate running sports to drive the bicycle to move forward, the treadmill effect is better, the speed is higher, and in addition, treadmill while standing is a new sports manner, a pedal bicycle rider can do sports with the whole body and do physical exercise better.

Description

technical field [0001] The present invention relates to a pedal bicycle. Background technique [0002] Health is the greatest happiness in life, and exercise is an important guarantee of health.
