A tire cleaning mechanism for a wheelchair comprises a fixation portion, a tire cleaner assembly, and an activation assembly. The fixation portion is operable to fixate the tire cleaner assembly to a wheelchair frame. The tire cleaner assembly is operable to remove debris from a wheelchair tire and the activation assembly is operable to move the tire cleaner assembly between an engaged configuration whereby a portion of the tire cleaner assembly engages a wheelchair tire and a disengaged configuration whereby the tire cleaner assembly is substantially removed from the wheelchair tire. A first link is coupled between at least one of a fixation portion and the tire cleaner assembly, or between the activation assembly and the tire cleaner assembly.

A wheel brush assembly for use of the wheelchair that includes: a housing; a spring within the housing, where the spring extends from a first end of the housing; a brush that abuts one side of the spring at a first end of the brush; a plurality of bristles on a second end of the brush that extends out of an opening of the housing; and a magnet that enables the attachment of the housing onto a wheel brake. The plurality of bristles come in contact with a wheel of the wheelchair during operation, wherein the spring urges the plurality of bristles into contact with the wheel. Preferably, the plurality of bristles disengages with the wheel upon application of the brake.
