The cadillac of mopeds? Actually, it's the Jawa of Puchs. I mean, Jawa made it.
The hero puch he linked to is a two speed. ADs are a E50 variant, kind of like the Dart engine. Oh, and those are 16" five stars, not the five stars that go on magnums and maxis.
But if it really does run as well as he says, it's a fair price and a nice bike.
