The good guys hit garage sales and flea markets and pick up their inventory cheap, clean them up and make sure they are in good working order and then make a reasonable profit on them based on market value. There's several of those type on CL here and they probably make a pretty decent income at it.
Well, I hope to fit this description. I basically do only garage sales, usually finding box store bikes that they don't want. I like to pay $20 or less, or in the rare instance it's a TREK or name brand, I will pop for more. I don't buy off CL, as sellers all want to get as much as I would charge, and they are in junk condition.
I clean them up, fix flats if necessary, replace a few parts if I'm not getting in over my head, adjust everything so that it stops, shifts, and rides as well as it can be made to perform, (they are box store after all). I figure out about what the bike sold for new and price it at 1/2 that. I have Very Few on my junk pile that I have had to keep, and they provide the odd part when needed. 1/2 price is attractive to most folks shopping CL who don't want to spend full price +tax.
On CL, post good descriptive pictures, not some blurry image taken of the bike laying out in the yard or in the garage with a very distracting background. People want to see what you have for sale. Avoid personal stories, just describe the bicycle. Be clear, I always add "Being Sold: Used As-Is , Cash Only, Local pickup Only". Be able to monitor your email, phone calls, and especially Text. Respond quickly, they are probably looking at other ads. Don't get all uppity when they ask if you still have the bike --- they always do -- Say Yes and offer to show it to them at their convenience. Works every time!
It's not "a pretty decent income", but it's generally worth it to me to do this. All the bikes I own and want to keep were paid for by these small profits.
I used to try to do this with old bikes, but they are getting few and far between, and owners want full price for them. Nothing wrong with that, it's just not for me any more. I will keep the old bikes I have and like.
I did not grow up with BMX like Ratrod, I don't know them, so I leave that segment to him and others.
One Hard and Fast Rule:::::: Never buy a kids bike and expect to flip it:::::: There are millions of them out there and CL is full of them for $20 and less.
