Abstract

A method of upgrades a conventional human powered Hand Cart over to Electrical Smart Electric Hand Cart that is powered by an electric motor which gets its supply from batteries. The batteries must be mounted and installed at the electric Smart Electric Hand Cart without compromising riding comfort ability. The battery operated electric Smart Electric Hand Cart is meant as a challenge to get, on sunny summer days, the most pedal assistance as possible out of the battery operated used. It may not cost substantially more energy to drive the battery operated electric Smart Electric Hand Cart, when not powered, than a normal Hand Cart. When there is no charging or the alternate batteries are empty the Smart Electric Hand Cart should still be light running. E-bikes need large and heavy batteries to allow riding long distances, because the battery is charged only once at home.
