Query: Wrong Decision

Never buy the cheapest product. This bike was excessively heavy (50 pounds) compared to the normal 30 pound bikes they have. Thus, the cheap brakes were quickly worn down and eventually my derailer AND chain broke. I live in a hilly area so getting from one place to another required me to go uphill often, which was very difficult and energy-consuming. If you live in a flat area, I guess this bike would be okay, but going uphill constantly was terrible, and going downhill wore out those brakes. Biggest problem was that it was WAY too heavy.
