In the lessons

In maths: a vehicle counted (2 wheels each), or one that travels at a speed: distance = speed × time. Safety: motorbike riders must wear helmets; motorbikes are fast and hard to see, so look carefully before crossing. Everyday life: a police motorbike, a delivery motorbike. Phrases: ride a motorbike, on a motorbike, motorbike helmet.
