I have no clue what happened to my derailleur on my bike. I can ride the bike and after a couple of cranks the chain gets really lose and seems like it's about to come off so I stop pedaling and wait and then the tire does a couple of rotations and the chains tight again.

  • It sounds like you have chain suck. Are your cogs/chainrings wornout? – Batman Dec 24 '15 at 5:04
  • No my cog and chain are in good shape – Vitaly Dec 24 '15 at 5:07
  • Hey I have a pic how do I put it up on here – Vitaly Dec 24 '15 at 5:08
  • theres an image button in the editor. It'll upload the image to imgur and then display it. – Batman Dec 24 '15 at 5:09
  • I still have no clue where that is. – Vitaly Dec 24 '15 at 5:18

Chain looks too long to me. Shorten the chain.

Not gong to guarantee that will fix the problem but it looks like part of the problem to me.

  • When I just got the bike it was normal until I started to do wheelies and then that's what happened to my rear derailleur – Vitaly Dec 24 '15 at 7:14
