The Electromote was the world's first vehicle run like a trolleybus
A trolleybus is an electric bus that draws its electricity from overhead wires using spring-loaded trolley poles. Two wires and poles are required to complete the electrical circuit...

. The Elektromote operated from April 29 to June 13, 1882, on a 540 m (591 yard) trail-track starting at Halensee train station, and thence to “Straße No. 5”, today's Joachim-Friedrich-Straße, and “Straße No. 13”, today's Johann-Georg-Straße, crossing the Kurfürstendamm
The Kurfürstendamm, known locally as the Ku'damm, is one of the most famous avenues in Berlin. The street takes its name from the former Kurfürsten of Brandenburg. This very broad, long boulevard can be considered the Champs-Élysées of Berlin — full of shops, houses, hotels and restaurants...

Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles...
to the rear wheels. The voltage used was 550 V
The volt is the SI derived unit for electric potential, electric potential difference, and electromotive force. The volt is named in honor of the Italian physicist Alessandro Volta , who invented the voltaic pile, possibly the first chemical battery.- Definition :A single volt is defined as the...
Direct current is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also flow through...

power lines. In English language use, the Kontaktwagen was later named the "trolley", giving the trolleybus its name.
This experimental vehicle already fulfilled all the technical criteria of a typical trolleybus. After the demonstration runs closed on June 13, the test track was dismantled on June 20, 1882.
