Abstract
A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.
Claims19
A pedaled drivetrain on a stationary exercise device, the drivetrain comprising:
- a drive mechanism;
- a flywheel having a rotational axis;
- a freewheel hub connecting the drive mechanism to the flywheel and configured to transmit torque from the drive mechanism to the flywheel in a first rotational direction around the rotational axis;
- and
- a locking mechanism having a locked state and an unlocked state, the locked state configured to transmit torque from the drive mechanism to the flywheel in at least a second rotational direction around the rotational axis, wherein at least a portion of the locking mechanism extends through the flywheel.
A stationary cycling system, the system comprising:
- a frame;
- handlebars supported by the frame;
- a drivetrain supported by the frame, the drivetrain including:
- a drive mechanism configured to receive an input torque from a user;
- a flywheel;
- a freewheel hub connecting the drive mechanism to the flywheel and configured to transmit the input torque from the drive mechanism to the flywheel in a first rotational direction of the flywheel only;
- and
- a locking mechanism connected to the drive mechanism and the flywheel, the locking mechanism having a locked state and an unlocked state, the locked state configured to transmit at least 95% of the input torque to the flywheel in the first rotational direction and a second rotational direction of the flywheel, the second rotational direction being opposite the first rotational direction, wherein at least a portion of the locking mechanism extends through the flywheel.
