Bicycles can be used as an environmentally friendly means of transportation and travel, and increasingly, they're used as exercise equipment for exercise and travel.

[0003] Chinese Patent Publication No. CN201158441Y, published on December 3, 2008, discloses a full-circle force pedal for a bicycle. The pedal comprises a pedal shaft, the other end of which is fixedly connected to the inner ring of a ball bearing, the outer ring of which is fixedly connected to the central hole of a pedal plate. A pedal rod is fixedly connected to each of the three outer edges of the pedal plate. The three pedal rods extend vertically and parallelly from the pedal plate. The pedal plate is triangular in shape, with three pedal rods located at the three corners, each with a soft rubber sleeve. However, a disadvantage of this patent is that the pedal plate is prone to tilting when stationary, requiring the user to adjust the pedal plate to a horizontal position before riding, which is inconvenient.

[0004] In summary, there is a need for a bicycle pedal structure that can improve riding convenience. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art in that the pedal board is prone to tilting when in a static state and the user needs to adjust the pedal board to a horizontal position before riding, which is inconvenient to use, and provides a pedal structure for a bicycle that can improve the convenience of riding.
