What is wrong with my bike?

[jaydenthecreator]

Could someone help me out? I recently purchased a new single speed bike sprocket. I put it on my bike and I had to make the chain smaller. Anyways I got everything put together and its as if the bike doesn't have enough tension when you pedal. like when you pedal it feels like the chain isn't even on. the cranks spin almost to freely.

Even odds you installed the single speed freewheel backwards.  What happens when you pedal backwards?
