Abstract
A wheel and hub assembly for a vehicle includes a clutch dog pivotally attached to a wheel. A toothed ratchet wheel is attached to a pedal crank and positioned adjacent to the clutch dog. A hub cover includes a protrusion. The hub cover is attached to the wheel in a sliding fashion so as to slide between an unlocked position, where the protrusion engages the clutch dog so as to prevent the clutch dog from engaging the toothed ratchet wheel when the pedals are turned in a forward direction; and a locked position, where the protrusion does not engage the clutch dog so that the clutch dog engages the toothed ratchet wheel when the pedals are turned in a forward direction.
