Invented by Swiss wheelchair user and outdoor enthusiast Patrick Mayer, Wheelblades offer chair users greater access in snowy conditions. Wheelblades attach to front casters of manual chairs; the Wheelblades’ greater width distributes the user’s weight and propulsion energy over a greater surface area to keep casters from sinking into the snow. Two tracking channels on the underside of the Wheelblade compresses snow to ensure stability. Wheelblades can be easily and quickly attached to front wheels measuring 1.8 to 6 cm wide (approximately .71″ to 2.36″ wide).
