hairdryer
A rice rocket is a Japanese bike. Now they're quieter. They sound like a hairdryer when they're idling. Like when your dad’s car makes that annoying noise at stoplights.
My cousin’s rice rocket is so quiet, it’s like it’s hiding.
That bike sounds like my sister’s hairdryer when it’s on low.
My uncle’s rice rocket is so quiet, it’s like it’s whispering.
