An exercise machine comprising: a frame supporting a wheel; a brake arm pivotally coupled with the frame and moveable between at least a first position and a second position, the brake arm including at least one resistance element positioned proximate the wheel, and the first position associated with a first braking force on the wheel and the second position associated with a second braking force on the wheel, the second braking force greater than the first braking force; and a brake arm adjustment assembly comprising: a housing fixed relative to the frame, the housing translationally and rotatably supporting a shaft; a member operably fixed relative to the housing, the member defining a first surface separated from a second surface by an axial distance relating to a separation between the first position and the second position; a lever assembly rotationally supported by the shaft, the lever assembly including at least one projection, the lever assembly rotatable about the shaft and relative to the housing to selectively move the at least one projection from engaging the first surface to engaging the second surface, the movement of the lever assembly causing the shaft to translate the distance separating the first surface and the second surface and move the brake arm from the first position, associated with the first surface, to the second position, associated with the second surface. a frame supporting a wheel; a brake arm pivotally coupled with the frame and moveable between at least a first position and a second position, the brake arm including at least one resistance element positioned proximate the wheel, and the first position associated with a first braking force on the wheel and the second position associated with a second braking force on the wheel, the second braking force greater than the first braking force; and a brake arm adjustment assembly comprising: a housing fixed relative to the frame, the housing translationally and rotatably supporting a shaft; a member operably fixed relative to the housing, the member defining a first surface separated from a second surface by an axial distance relating to a separation between the first position and the second position; a lever assembly rotationally supported by the shaft, the lever assembly including at least one projection, the lever assembly rotatable about the shaft and relative to the housing to selectively move the at least one projection from engaging the first surface to engaging the second surface, the movement of the lever assembly causing the shaft to translate the distance separating the first surface and the second surface and move the brake arm from the first position, associated with the first surface, to the second position, associated with the second surface. a housing fixed relative to the frame, the housing translationally and rotatably supporting a shaft; a member operably fixed relative to the housing, the member defining a first surface separated from a second surface by an axial distance relating to a separation between the first position and the second position; a lever assembly rotationally supported by the shaft, the lever assembly including at least one projection, the lever assembly rotatable about the shaft and relative to the housing to selectively move the at least one projection from engaging the first surface to engaging the second surface, the movement of the lever assembly causing the shaft to translate the distance separating the first surface and the second surface and move the brake arm from the first position, associated with the first surface, to the second position, associated with the second surface.
