Abstract

A portable bicycle which can drive by stand user and reciprocal back-pedal driving comprises a front wheel, a back wheel, a handle bar, a support and a driver. A fixed pedal is at two sides of the back wheel, to move back and down the weight center of the bicycle, while the fixed pedal is hinged with a movable pedal connected with the back wheel. The invention has small volume, high speed and saved driving force.

Description

Technical field [0001] The utility model relates to a small bicycle reciprocatingly driven by pedals. Background technique [0002] Because the pedal reciprocating drive is labor-saving, it represents the general direction of bicycle development. But this type of vehicle has not been popularized and used in a large area so far. The reason is that in addition to the process of people's understanding of the new type of vehicle, it is also because some straight pedal bicycles have a more complicated structure, or the body has not been significantly reduced, or Insufficient performance and so on. Contents of the invention [0003] In order to overcome some shortcomings of the reciprocating pedal bicycle, the present invention designs a bicycle with a compact body, a simple structure, and is light and fast. [0004] The technical scheme that the present invention takes for solving technical problems is: [0005] 1. Move the fixed pedal backwards to both sides of the rear whe...
