1. A pedal drivetrain, comprising:
a drive mechanism;
a flywheel having a rotational axis;
a hub connecting the drive mechanism to the flywheel in a first rotational direction around the rotational axis; and
a magnetic clutch connected to the drive mechanism and the hub, the magnetic clutch moving the hub between a locked state and an unlocked state based on an application of an electric current, wherein, in the unlocked state, a first torque applied by a pedal in the first rotational direction is transferred to the flywheel and a second torque applied by the pedal in a second rotational direction is not transferred to the flywheel.
