Ahh I honestly wouldn't bother with it. It is far from a mountain bike. Dont spend $230, save your money.
Why? All the parts are very basic, mostly OEM, no name. The headset is...well the other style and the drivetrain is below average.
Sorry to sound like an idiot, but dont buy the bike. Save up another $100 and please, try Trek, Specialized or Kona or Giant bikes. You see for your price range you should be buying off a big name company, they offer best parts for your money.
