Hi!
I've got this new bike which was poorly put together as a show model at a retail location.
I trued and adjusted the brakes to my liking as they were barely functional and tightened a variety of things, but I'm not sure what's wrong with the derailleur/chain/hub, I'm pretty sure it's something basic, so bear with me here.
When I rotate the pedals clockwise (with the bike upside down), simulating forward pedalling the wheel moves, however, when I mount the bike and pedal forward, I get ahead and then I feel the lack of force and stop moving- as though the chain slipped off. After a few rotations it catches on again resulting in the bike moving forward.
Moving the pedals backwards results in a strange noise that isn't just the clicking sound of the freewheel, it sounds a lot more like something rattling (along with sporadic freewheel clicking). All in all, the bike feels pretty unstable and unridable because of this.
I'm not sure what's wrong or what I need to do..
is the cassette not properly attached to the inner part of the hub?
Or is it something with my chain and derailleur?
I really have no idea, although I'm willing to learn, deduce and solve the problem.
Also, I know my description was poor in some areas, so he's an equally poor video:

Note how the chain or freewheel seems to skip.
Any suggestions?
