They say ignorance is bliss, so I'm guessing you're one happy guy, lol. Definitely a bad "hariness", lol, lol. You know, if you take it to a barber, he can fix that for you, lol.
You may be one of the more incompetent wrench turners to come along on this site in some time but you certainly seem to know a thing or two about price gouging. Let's see, you bought the bikes for $60 a week or so ago and now you're trying to sell them for $400. What's that, like a near 7-fold mark-up ????? Now I could see a mark-up if you bought a bunch of parts, fixed the bike up, and got it running like a top - but you've done nothing of the sort. You haven't fixed squat. You can't fix it because you lack the skills. In fact, my guess is the machine is in worse shape now after you've been "fixing" it than it was when you got it, lol.
