I purchased a Mangna PK-7 yesterday, and after riding it for a bit, i noticed this awful squeeking noise whenever i press down on the left pedal. I think it's coming from the crank arm, in fact, i'm almost positive it is. The sound is like a goose, or donkey being strangled or something, like a creaking noise. A noise that I absolutely cannot tolerate whilst riding. A noise that makes me shout loud obscenities around young children. Please, i am completely ignorant when it comes to managing and taking care of a bicycle, so don't expect me to understand bike jargon or anything. Walk me through it as though i were 5 years old please. Help would be much appreciated. Thanks!
