Thank you guys for the suggestions!
I realized my chain was way too tight and that was the cause of the difficulty rolling. Unfortunately I have come across a new problem. The piece of metal connected to the rear brake caliper has cracked due to my use of excessive force in torquing the rear axle nut. The weird thing is that my front brake is also having issues now.
I'm posting some pictures to give you guys an idea of what's going on.
