Portable Bicycle Reduction Gear

Abstract

The invention relates to a portable bicycle decelerator, which comprises a base, wheels, a roller device, a transmission device and a support steering device, wherein the wheels are rotationally connected onto the base; the roller device is used for carrying a back wheel of a bicycle; the transmission device is connected between the roller device and the wheels; the support steering device is arranged between the base and a bicycle frame of the bicycle; the transmission device comprises a first gear and a second gear; the first gear is coaxially and fixedly arranged on the roller device; the second gear is coaxially and fixedly arranged on the wheels and is in engaged transmission with the first gear; the support steering device is a support steering rod arranged between the base and the bicycle frame of the bicycle; the lower end of the support steering rod is provided with a pin shaft and is rotationally connected with the front end of the base; the pin shaft is arranged along the front and back direction; the upper end of the support steering rod is detachably connected onto the bicycle frame of the bicycle. The portable bicycle decelerator has the advantages that the matched training with the existing bicycle can be realized, the riding speed of the bicycle is decelerated, the training effect is achieved, in addition, the controllability is good, the structure is simple, the carrying is convenient, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a portable bicycle deceleration device. Background technique [0002] With the continuous acceleration of the pace of life, people have less and less time for exercising, and fitness equipment has become the choice of more and more people, such as bicycle training devices. Chinese patent CN204034220U discloses a hobbing-type bicycle riding simulator, but The simulator can only be used for in-situ training, and the simulator is divided into two parts, the front and the rear, which are large in size and weight, and extremely inconvenient to carry. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a portable bicycle deceleration device, which can not only cooperate with existing bicycles for training, reduce the riding speed of bicycles, and achieve exercise effects, but also has good controllability and simple struct...
