A motorcycle is a vehicle with two wheels, an engine, and no pedals. Don't forget to wear a helmet when you jump on your motorcycle!
Like a bicycle, a motorcycle has two wheels, but while you power your bike by pedaling, a motorcycle's motor takes care of that. All you have to do is keep it full of gasoline. Motorcycles don't burn as much fuel as most cars, so they are a major form of transportation in many cities. Unfortunately, they're also much more dangerous. When motorcycles were invented in the 19th century, they were also sometimes called motocycles.
