Another Retrofittable Electric-Powered Wheelbarrow Wheel - Core77
I've drooled over Makita's battery-powered wheelbarrows, which would make yardwork and homesteading far easier. But they run about $5,000, and they're Japanese-market only. Another Japanese company, CuboRex, designed this E-Cat. It's a retrofittable electric wheel that can be added to any wheelbarrow. However, it costs $1,261.
