They sold me the bike and the back brakes are making the loudest noise after you stop peddling. It sounds like your driving a Motorcycle that how loud..
This is a great bike except thar it arrived with a hole in the tube of the rear wheel. My Granddaughter loves the bike and was so excited to receive it on her birthday.
This bike was nothing but trouble. I came out of the box damaged and needed a good tune up. Better off buying at store already assembled.
