Bike pedals and chain stuck! Help?! 10 points!?

Question

The pedals on my bike dont move! I just was sitting on top of my bike and the the change made this weird noise!

The pedals didn't move forward and the chain is stuck! I can bike backwards but that would bring me NO WHERE! and when I tug on the chain it won't move!

help me plz!

Answer 1

Pull the chain off.

Spin it forward a couple times, then replace the chain.

Answer 2

get the chain hooked on to the bottom of the front cog (the one at the pedals) then try pedaling backwards this should get the chain back on..................

                        

................now, the pedals should be turning freely, but if not buy some oil (wd-40 is one brand)  to spray on it and it should be working fine....................

                                

....................it will help if you turn the bike upside down and leave it resting on the handle bars and saddle while doing these things!!!!!!!!!!!!!!!!!!!          

best of look :-)
