Magnetic-loaded exercise bicycle

Abstract

A magnetic-loaded exercise bicycle comprises a bicycle frame, a flywheel, a magnetic loading device, and a pedal device, wherein the flywheel is mounted on one side of the bicycle frame and the magnetic loading device is mounted on the bicycle frame inside the flywheel. When the rotatory arm is rotated, the hook is shifted within the arc-shaped trench of the fixing plate such that the distance between the magnets and the flywheel can be adjusted by shifting the rotatory arm, thereby adjusting the magnitude of the magnetic control force for increasing or reducing the loading of the flywheel. As a result, the magnetic-loaded exercise bicycle has simple structure, accurate loading, and easy maintenance.

1 . A magnetic-loaded exercise bicycle comprising: 
 a bicycle frame, a flywheel, a magnetic loading device, and a pedal device, wherein the flywheel is mounted on one side of the bicycle frame and the magnetic loading device is mounted on the bicycle frame inside the flywheel,    wherein the magnetic loading device comprises a fixing plate, a magnetic control device, an elastomer, a connecting plate, a steel rope, an elastic shaft, and an adjusting handle, wherein the fixing plate is fixed on the bicycle frame and provided with an arc-shaped trench,    wherein the magnetic control device comprises a plurality of magnets and an arc-shaped rotatory arm, wherein the magnets are fixed on an outer surface of the rotatory arm and the elastic shaft and a shaft-fixing device are designed for pivotally coupling one end of the rotatory arm to the fixing plate, wherein a hook is mounted on an inner surface of the other end of the rotatory arm for being inserted into the arc-shaped trench and the connecting plate is fixedly connected to one side of the rotatory arm, and wherein one end of the steel rope is inserted into the elastomer and fixedly connected to the connecting plate and the other end of the steel rope is connected to the adjusting handle such that the adjusting handle can adjust the magnetic control device by controlling the steel rope.
