Abstract
A hybrid bicycle pedal and crank system includes a chain ring, a foot peg mount disposed on at least one side of the chain ring, and a foot peg rotatably mounted to the foot peg mount on at least one side of the chain ring and configured to rotate from a pedaling position in which the foot peg is offset from a center axis of the chain ring to a fixed foot peg position in which the foot peg is fixed in alignment with the center axis of the chain ring.
Claims7
A hybrid bicycle pedal and crank system, comprising:
- a chain ring;
- a crank arm assembly disposed on at least one side of the chain ring and including an inner crank arm and an outer crank arm;
- a locking pin mounting bracket;
- a bottom bracket that protrudes through a center axis of the chain ring;
- a crank assembly locking pin disposed on the bottom bracket and configured to retract;
- a foot peg mount disposed on the at least one side of the chain ring;
- and
- a foot peg rotatably mounted to the foot peg mount on the at least one side of the chain ring and configured to rotate, when moved by a user, from a pedaling position in which the foot peg is offset from a center axis of the chain ring to a fixed foot peg position in which the foot peg is fixed in alignment with the center axis of the chain ring,
- wherein the inner crank arm includes a first end and a second end and is mounted to the bottom bracket that protrudes through the center axis of the chain ring on the first end,
- wherein the outer crank arm is rotatably mounted to the second end of the inner crank arm, and
