Mongoose Mountain Bike 21-S 27.5" Wheels

Got the bike really fast. Loved the color and had to wait for almost a month until my bike repair guy was back from vacation. Brought the bike to him to assemble. Got it put together and I took it for a spin. Brakes were horrible. I couldn't switch gears properly. He adjusted everything replaced all cables right away. Brakes then worked amazingly! He worked on my gearing for almost three hours (granted we were talking a bit) but pulled out every trick in the book. Could not figure it out. Huge disappointment. Sent back and got a refund but I'm out the cost him working on it and my time taking it apart and boxing it back up. Brought it to ups and they told me because the corner of the original box was wet they had to repack it and charged me for it. I did however get the cost of the ups back. Overall not happy with the product!
