Schwinn Meridian trike not pedaling I'm the third owner of this trike and I ride it EVERY day.I noticed a few days ago that I had no resistance when pedaling and then this morning it stopped altogether, I hopped off and checked it. The axle there the back chain connects was moving, but  where the front chain connects was not moving. I started to walk it home and it started to work again. 

What's wrong and how do I fix it? I live in a town where NO ONE does trikes or bikes, and I don't have any way to take it somewhere to fix.

I posted about this about two years ago and the other trike is no longer on the road. New trike (got it about a year ago) is now having the same issue as the last. It's no longer pedaling. I have a video on twitter that I just did to explain it better.

Please help! This trike is my only ride!
I'd guess the single-speed freewheel/freehub on the jackshaft has something wrong with its pawls.

That's the bit that lets you coast along without pedalling, and the rear chain will keep moving with the rear wheels.

To fix it temporarily you could try flooding the freehub with solvent and wiggle it lots.  When its moving better let the solvent dry off, and lubricate it after a while.

The permanent fix  would be to replace that freehub unit on the jackshaft.

The prevention would be to store the bike in a garage or inside, and to rinse the transmission off after every winter ride - I see a bit of corrosion there which could indicate the cause.
