Re: a pat on the back...
My weed whacker bike does get a little pedaling and I tell my wife that's my exercise. About five strokes up a short steep hill. On a long steep hill, its like pedaling a bike on the flat. So yeah it is better for my heart I'm sure.
But if I have to go to the store, it is still the china bike and no pedals.
