The Beach Econo Kit is a kit for converting a wheelchair or stroller into an all-terrain wheelchair or stroller designed for use by individuals with lower extremity disabilities, mobility disabilities, and spinal cord injury. The kit consists of four balloon wheels from Roleez Wheels, Inc. (see separate entry), two pre-drilled anodized axles, u-bolts, and wheel clips. To mount, the rear wheels are popped off, the axle tubes are slid across the frame and bolted on, and the balloon wheels are slid on to the axles and pinned. The front caster wheels ride above the terrain. The hardware is made from aircraft aluminum and stainless steel. DIMENSIONS: Wheels are either 30, 42, or 49 centimeters in radius.
