Automobiles are vehicles for transportation of people or goods. Most definitions define an automobile as having four wheels and seating up to eight passengers. They run on roads or on tracks.

Cars have been designed and manufactured to be safe and comfortable. The engine and transmission are usually of a petrol or diesel powered. Modern cars are made of thousands of parts and employ a range of technologies.

The first commercially manufactured motorcycle was created in France by Ernest Michaux. This motorcycle was equipped with a horizontal single-cylinder gasoline engine. It had a drive chain attached to the rear wheel.

After its debut, more inventors began to design better motorcycles. One such design was the Daimler Reitwagen. It was produced in 1894 and predated ICE automobiles by one year.

Initially, the motorcycle was a hybrid of bicycle and motorbike. Bicycles were often equipped with small spark ignition engines.

The term “motorcycle” was originally used for pedal cycles. These were adapted with an engine and were sometimes called “pedal cycles.” However, the term can be applied to any self-propelled machine.

Today, most mass-produced motorcycles are steel or aluminium frame machines. Typically, these motorcycles feature disc brakes, telescopic forks holding the front wheel and other body parts.

There are three major types of motorcycles: street, off-road, and dual-purpose. Motorcycles are dual-purpose vehicles, which can be used for both light and heavy traffic.

While the definition of a motorcycle can vary, it generally means a self-propelled machine with a seat for the rider and two or three wheels that contact the ground. Riders should wear a helmet.
