The first electric tricycle
The first electric tricycle in the world was born in 1881. Its inventor was Gustav Truff, a French engineer. It was a tricycle powered by a lead-acid battery. In 1873, the electric tricycle, which was invented by Robert Davidson, an Englishman, powered by a primary battery, was not included in the scope of international confirmation. Later, lead-acid, nickel cadmium, nickel hydrogen batteries, lithium-ion batteries, and fuel cells emerged as electric tricycle.
