Want to buy a Spinning Bike or Spinner Bike

want
- very quiet
- strong resistance level
- maintenance free ( is it possible ? as i hate the fact that my magnetic exercise bike need to repair from time to time for the belt, otherwise it makes noise)

Will those spinning bike need to send for repair and change belt as well ?

Should i choose
fly wheel only model ?
magnetic only model ?
both fly wheel and magnetic model ?
or other new invention ?

Any model will add a cooling fan ?

Thanks for tips
