Good question.
No.
"Bike" is short for bicycle.
"Bi" = 2
Bicycle = 2 wheeled cycle
Motorbike = motorised 2 wheeled cycle
Quad = 4
"Quadricycle" = 4 wheeled cycle
Motorquad = motorised 4 wheeled cycle
So really in your context, "quad" is a motorquadricycle
It's more a question of different rather than "better". A quad is easier to ride, but a motorbike is more nimble and handles differently.
Just like a motorbike except on most quads there are thumb throttles instead of twist throttles.
In UK at least a full B1 you cannot ride a quad on a motorbike licence.you just need a full UK drivers license to drive a quad (if your in the UK), you also don't need to wear a helmet as its not a legal issue :D

I usually trace it when drawing a motorbike.
Kawasaki is the best 50cc motorbike.
a motorbike would cost about £2000-£10000 it depends on witch motorbike you are buying
It depends on the make and model how much a motorbike weighs
