A motorcycle is a two-wheeled vehicle powered by an engine. It is a popular form of transportation and recreation. The term 'motorcycle' can refer to a variety of vehicles, including scooters (7 letters), bikes (4 letters), mopeds (5 letters), and mamas (4 letters). Scooters are typically lightweight and have small engines, while bikes are larger and more powerful. Mopeds are similar to scooters but have pedals that can be used to propel the vehicle. Mamas are a type of motorbike with a step-through frame and a low seat height.
