I often hear the term "Quad Bike", does that mean a vehicle with 42 wheels or 24 wheels or 8 wheels? I have no idea!

Exactly. Quadrant, quadrangle, quadruped, quadruplets etc.Isn't quad from Latin?
Roughly translates as 4


?Well quad is 4 and bi is two, so quad bike is a nonsense term, it can be a quad (4) or a Bike (2) but never a quad bike unless it is 42 (or even) 24 or better still 2 x 4 = 8, I suppose we might stretch it to 2 to the power of 4 or 4 to the power of 2 for fair play. So what the heck is a quad bike then?
Oh, come on!So what the heck is a quad bike then?
Nope. a Bike has two wheels otherwise it is not a bike.Oh, come on!
In this case, the word bike the word bike is used as a noun, not as a number, and the work quad is an adjective.
The adjective is describing the noun.
Therefore, it is a bike with four wheels.
What about the two legged type, do we need to find another word for them?otherwise it is not a bike
