a multifunctional bicycle

Abstract

The invention discloses a multifunctional bicycle which is mainly composed of a bicycle body part, a brake part, a driving device, a caterpillar band part, a skiing and skating part and a propeller part. The multifunctional bicycle can be suitable for being ridden on multiple terrains such as a road, sand, a snowfield, an ice surface and a water surface by replacing different parts.

Description

technical field [0001] The present invention relates to a bicycle, more particularly to a multifunctional bicycle that can be used for riding on various terrains such as roads, sandy fields, snowy fields, ice surfaces, and water surfaces. Background technique [0002] At present, there are mainly two kinds of devices that rely on people's own power to drive long-distance displacement, one is a two-wheeled bicycle, and the other is roller skates. Although these two devices can lead people to move forward with less effort, they still have significant disadvantages: [0003] 1. The front and rear wheels of a two-wheeled bicycle are large, the body is high, and the center of gravity of the rider is also high, so it is easy to fall in an emergency; [0004] 2. The front and rear wheels of the bicycle bear the weight pressure of people. Because the wheel diameter is large and the rim is supported by steel wires, the part of the tire that touches the ground is deformed by pressure...

AI Technical Summary

Problems solved by technology

[0006] 4. The multiple sliding wheels of the roller skates share the weight of the human body and can slide forward easily, but the roller skates need to be fixed on the feet, which not only requires considerable skills, but also is unsafe to slide on the road

[0007] 5. Bicycles and roller skating rely on people's most powerful feet to ride / slide. They are two relatively labor-saving means of transportation, but their scope of use is limited, and they cannot be used on sand, snow, ice, or water.
