If this is a coaster brake bike (single speed, no hand brakes) then the problem might be inside the rear wheel hub. If that is the case then you can only fix it by completely dis-assembling the rear wheel hub - or it might be simply that the chain is slipping, which would not happen unless the chain is too loose which would be indicated by the bottom of the chain hanging down too low. However, if this is a multi-speed bike, then it could be that the chain and rear-wheel cogs are worn - which can be fixed by replacing the freewheel and the chain - however, it takes a lot of use or rust and dirt before that level of wear happens.
Find the joiner link on the chain, remove the retainer clip followed by the link. Remove the chain. Remove the bolt holding the brake arm to the frame. Loosen the axle bolts on the wheel enough to be able to slide the rear wheel out of its slots on the frame.
Check your nuts that hold the "guts" into the center of the bike rear wheel.
Sometimes when they are too tight it causes the problem you are talking about.
Remove the rear wheel assembly
Once you have the rear wheel assembly removed from the bike, hold the axle and rotate the wheel, it should spin easy, if it spins rough or not at all, then loosen the nuts.
The nuts are after you remove the axle nuts.
Please take time to rate me
remove the rear wheel,, and when replacing it again,, turn the brake one turn to tighten the brake itself. to do this you need to hold the opposite side of the axle so it doesn't turn , if this procedure makes it to tight for normal free play, then the "pads" are worn and need to be replaced. they are the half circle looking metal plates that are inside the rear wheel hub,
Should not be all that difficult but you will need a few different wrenches. One for the wheels axle nuts and one for the coaster brake assembly. All coaster brakes work the same, so any coaster brake manual will work. Your local shop can also show you how to remove and install the wheel.
Sounds like a pawl is broken inside the hub. I would take it in and have the hub rebuilt or just buy a new wheel. It depends on what your bike shops charge for labor, parts are not expensive but it is a lot of work. There about 88 little parts in a rear 1 speed hub, so it may make better sense to buy the new wheel.
Release rear brake, either will have a lever on brake assembly or remove a brake shoe, shift to the smallest gear in rear, then loosen with a #15 metric box wrench, then push the wheel out. All bikes are metric, not just Schwinn. Then reverse to reinstall.
If I remember correctly there should be holes in the hub with set screws to tighten the hub to the axle. The ones I built had square headed bolts. The reason is that the hub can be moved from side to side to better adjust how the chain lines up for shifting. If there are no bolts or set screws but the holes are there you can take the hub to a fastener place to obtain some. Hope this helps.
If the gears will no longer go back on the bike, I would recommend buying a new wheel (including a new rear hub). It is usually easier and more cost effective to buy a wheel than to replace the hub. To replace the hub (the part that is stripped on your bike) you would also have to remove and replace spokes, etc. Search online for the wheel size you need (probably 26" - you can check the tire size) or take to a reliable bicycle shop and they will gladly help you. Anyway, you need a new hub but probably better off getting a new wheel - much easier.
