Econo Kit
The Econo Kit is the least expensive and easiest way to convert your wheelchair or stroller into an all-terrain explorer. The kit consists of four wheels, either 30cm, 42cm, or 49cm, 2- pre-drilled anodized axles, SS u-bolts, and wheel clips. Easy to mount: It’s easy, just pop off rear wheels, slide axle tubes across frame and bolt on. Slide on balloon wheels and pin. No need to worry about front caster wheels. They ride on the terrain.
