Sounds like the freewheel mechanism is jamming up. You could try soaking the freewheel, where the sprockets are, in something like WD-40, but most likely, the sprocket is going to need replaced. Your local bike shop can provide the correct part.
SOURCE: when you pedal the front sprocket and chain turn
On the second gear from the front There should be a bolt that screws into the flange where the shaft goes through to secure it to the shaft. When this is tightened down it stops the gear from rotating on the shaft when you are pedalling. It is on the gear where the front chain provides power to the back chain. If the bolt is missing, you should be able to replace it with any bolt that is the same diameter and thread size as the hole in the flange. When I was still building these the bolt usually had a square head on it. Unfortunately I don't remember what size the bolt was. I hope this helps.

The hub needs serviced....normally one-way bearing isn't gripping in forward drive direction....recommend having serviced by dealer.

ok well its best decided how to fix it if you can tell me what style of rim and freewheel you have if the freewheel goes all the way to the tip of the axle then its more than likely a cassette style rim and if it appears hollow at the axle end and you can somewhat see inside the freewheel then i would just buy a freewheel cassette for it because in most cases a faulty freewhell body cant be serviced and need replaced when they fail up on you another cause of this is riding in the winter so find out what kind it is and message me back ok ill better inform you of the best possible way to ride happier longer :) this is also a super common problem ok
