unbelieveable shitty Quality

Today is Monday, I ran to work as usual. (Half Marathon) and when come to the trip home. I ride my pre-planned folding bike to take light rail home. After light rail ride. I still have to pedal few mile to where I parked my car. It was very dark and my bike doesn't have light, yet I wore a bright white jacket so I wasn't afraid anything, I just ride slowly. Along the way I felt the pedal kinda strange and it lasted for a while....... wow, the pedal and crank fall off! What the F**k! I bought this folding bike for $135 including shipping. I know it's cheap and Made in China; but I didn't expect this. In the dark, I searched for the fall off pedal and walk my bike for the remaining hald mile.... #@!&##
