  1. You need a new rear derailleur. Probably best to take it back. If you can’t afford a bike from a bike shop, at least have one check over the bike before riding. They can save you a ton in future repairs.

  2. Take it back to the shop, that is pretty expensive damage for a brand new bike.

  3. Hopefully it should only be about $30 for the part and half an hour mechanics time to fix it.
    And yes, if you’re transporting a bike on its side always have the chain side uppermost.

  4. I love how the cheap derailleur is even weaker than the explicitly weak designed derailleur hanger.

  5. The derailleur is bent. This may have been done during assembly or when you transported it. If you hit the bike hard when packing it, it’s on you. More likely, though, there was an accident beforehand.

    Buy a decent used bike. Target, Walmart et al are junk.

    Go to a bike shop and find out what size you need.

  7. You are already learning the difference in quality between real bikes and the “bike shaped objects” sold at Walmart and Target. One easy way to tell, if the axle is held on with a nut like this one then it’s not a real bike – it’s just junk. Take it back for a refund.
