Hello iOSGods, I am new here, and I would like to know how to unlock the ultra bike in bikerace tfg. I heard that it is impossible, but some have done it. I know how to use the nometres files to collect what I want, but if someone could create one where you get the ultra bike, that would be most needed. I already have All Bikes not including Army or Zombie; but those will be soon. Thank you if you can help, Centricks.
