i have the same bike except red and white.
my frame has been eaten through from the chain rubbing the lower frame arm so you will have to modify it by smashing it with a hammer or somethin i guess.
I'll be using this bike again, gonna get another one tonight and i will beat the **** out of that lower arm frame to make sure the chain does not rub again.
oh, i just got my bike set up with the disc brakes on the front then the rear lower frame got chain sawed through this morning while i was going down the road, luckily i noticed it at the gasoline station, but i still cried!
ride safe guys!
