Safety and mobility on wheels even in winter with snow and ice? With the WHEELBLADES this is no longer a question. Thanks to the easily adjustable binding, this practical aid can be attached to any common mauell wheelchair, baby carriage, rollator, rehab buggy and bicycle trailer. Thanks to the patented quick-release fastener, you can change from wheels to runners in a matter of seconds in just a few easy steps. The wide bearing surface of the WHEELBLADES distributes the weight optimally on the underground and prevents thus a sinking of the front wheels in the snow. The two treads glide over the ground with very little friction and even out larger unevenness without any problems. To ensure that the ski tip always points in the direction of travel, the binding was deliberately placed in the front part of the ski. Two running channels on the underside of the WHEELBLADES provide stability during the ride, compressing the snow and allowing you to glide as if on rails.
