Embodiments relate to a pedal system having a pedal coupled to a main drive shaft having a locked mode where the pedal does not rotate relative to the main drive shaft and a released mode where the pedal can rotate relative to the main drive shaft. In the locked mode, rotation of the pedal relative to the main drive shaft is prevented by a plunger that engages the main drive shaft. In the released mode, rotation of the pedal relative to the main drive shaft is enabled by having the plunger disengage from the main drive shaft. The pedal system is switchable between the locked and released modes. When a user's foot or footwear is engaging the pedal, the pedal is placed in the released mode, and when the user's foot or footwear is disengaged from the pedal, the pedal is placed in the locked mode.

A bicycle pedal includes a shaft seat, a shaft, a first pedal element and a second pedal element. The shaft seat has a shaft hole, a first threaded hole and a second threaded hole. The first threaded hole and the second threaded hole are separately located at symmetrical positions on two sides of an axis line of the shaft hole. The shaft is rotatably disposed in the shaft hole of the shaft seat. An end of the shaft has a thread for connecting with a crank. The first pedal element and the second pedal element are fixed to the first threaded hole and the second threaded hole by a first bolt and a second bolt, respectively. The first pedal element and the second pedal element are separately disposed at symmetrical positions on two sides of the shaft.

A bicycle pedal includes a pedal body with a first contact surface and an opposite second contact surface, a plurality of pins is arranged on the first contact surface, and a plurality of pins is arranged on the second contact surface. At least one of the pins has a tooth with a skew relative to the respective contact surface of the bicycle pedal, the skew of the tooth has an angle of between =5 and =45 with respect to a perpendicular to the respective contact surface, on which the pin is mounted.
