What type of transportation uses a two-cycle engine?

Two-cycle engines are commonly used in small, lightweight transportation devices such as scooters, mopeds, and some dirt bikes. They are also found in small outboard motors for boats and certain types of lawn equipment like chainsaws and leaf blowers. The simplicity and lightweight nature of two-cycle engines make them suitable for these applications, although they are less efficient and produce more emissions compared to four-cycle engines.
