Which of the following is NOT included in the definition of a Motor-driven Cycle?

Answer: C — bicycle

A motor-driven cycle is defined as a vehicle that has a seat or saddle for the rider and is designed to be propelled by a motor. This includes vehicles like motor scooters and motorcycles that fall within specific horsepower limits. The choice indicating a bicycle is the correct answer because a bicycle, by definition, is powered solely by human pedaling and does not have a motor. Therefore, it does not meet the criteria of being a motor-driven cycle. In contrast, a motor scooter is considered a motor-driven cycle as it has an engine and is designed for motorized transport. Similarly, a motorcycle that has a motor not exceeding five brake horsepower falls within the permitted specifications for motor-driven cycles. A standard motorcycle, typically equipped with a more powerful motor, is also included in this category.
