Bests & Worsts Reviews from Amazon

If I could give this bike 0 stars I would. We assembled the bike according to the included instructions. In addition to this bike we had also purchased a bike rack for our car for $70. On my first ride on this bike the rear derailleur tore off the bike while shifting gears. The bike came to a screeching halt. I was 5 miles from my car with a broken bike. Afterwards I brought it to a bike shop where they told me it will cost just as much to repair the bike as I initially paid for it. So now I’m left with a useless bike and bike rack. Very very disappointed! I would like a response from Amazon or Schwinn.
