    Pedal/chain problem

    Well first off to say I'm terrible with bikes.

    I recently went off a curb and heard a louder than normal noise from my chain area. Whenever I back pedal the chain becomes extremely lose and practically comes off the cog and changes gear when I start cycling forward. As well as this when I push the bike the pedals move forward which never used to happen untill I went off this curb.
    I can't really explain it since I have no clue what I'm talking about :x

    Check the rear deraileur - is the chain cleanly threaded through? It may have come off one of the wheels.

    Can you tell more specifically what happened? Did a part of your bike hit the curb, or was it only the harsh impact with the ground? If the former, what part of your bike made impact?

    I can't tell why your chain is coming loose, but the lack of coasting indicates something is wrong with your freewheel mechanism. If it's associated with this bump, it's possible you've bent the axle.

    You probably need to have a bike mechanic look at it, or at least someone who's knowledgable about bikes.

    Nobody can help you until you can adequately explain to us what the problem is. You want an answer? Take the time to write out a proper question.

    Since you don't know what you're talking about, it's unlikely that you will be able to fix it yourself. Take your bike to a nearby bike shop and let them take a look. You might just need a simple adjustment. On the other hand, you might have a bent deraillerur or hanger. The bike shop can figure it out for you.
