check your front quick release, it looks like it is open instead of closed.

She asked for a price, you paid it. That’s a “meeting of the minds/contract agreement. After that, the bikes are no longer her concern. Morally, should you have offered more? No. You didn’t know how much time, parts and effort you needed to get these back up to speed or what people would be willing to pay for them after they were repaired. You took the risk she was unwilling to take.

I'm fipping bikes for a side hustle too, and I think it's the sellers responsability to know what they are selling. I'm putting in 5-8 hours work on average on every bike, which includes transportation, maintenance, cleaning, taking pictures and doing the ad. Profit is usually around $50-$100, which is really not much if you divide it per hour. Any less and it wouldn't be worth it.

You overpaid for the bikes to begin with !!!!!!!!!!! She owes you a refund.

"Profit" is not a dirty word.

Got my wife a Trek Navigator off of Offer Up a year ago for 80 bucks. It was in GREAT shape! I was a little surprised... thought I would have to do some work on it but it only needed wiping down and I had to do a slight adjustment of the brakes- just turning the adjusters and that was it! Solid little bikes. Your seller was just upset that she didn't get more money. She agreed to the price and then you put tie and effort into it to increase the value that she either was not willing to do or not able to do. Fair play.

200 for the work alone is fair.

The woman doesn't understand fixing up an item isn't free. Parts and time (fast food employee wages start around $15 an hour) have costs. She's a kind person that would have a rear seal oil leak on a car and would think it should only cost the price of the seal and $30 for labor. She probably would give a quarter to mow her lawn.

People want to get the premium price without putting any money or effort into it. She's just bitter.

Maybe the person that owned the bike should've sold it for more money,

The lady is clueless! You paid way too much for that Trek. By the time you finished the maintenance, you had $300 bucks in the bike. You sold it for a loss.

Only thing I like about the bike is the fork but it's unicrown and not even lugged. The only reason this isn't a 50 dollar bike is cause of the Trek sticker. No one who buys this bike is gonna get a good value for their money so morally, you can't act like Ms Save the Neighborhood selling this for 175.

She named her price and you paid it. If I sell someone a clapped out beater car and they put the time into fixing it up so they can flip it, I have zero business thinking they took advantage of me. Same thing goes for bikes or anything else.

If you needed to work on the bike to make it saleable and it cost you; you are well entitled to add that to the original price. The parts and labor would have, at least, cost the markup dollars. Was she expecting to get it back for what she sold it for after work had been done to it?

But they had no problem selling it to you but have a problem selling it someone worse ? Make it make sense . Once you sell something that’s it buddy

Prices of 2nd hand bikes are also dependent on the condition that they are in, so not an issue if your markup reflects the amount of work and new parts needed to get them into whatever condition you are selling them in. With regards to the bike in the video, it needs more work before being resold, from just a quick visual from this video, there are a few things still to be done: front brake does not appear to be properly adjusted, front wheel quick release inserted on the wrong side, those dangling cables for the gear indicator should be removed.

Nahhh. I sell stuff on marketplace all the time. If she thought she could get more she should have asked for more. Plus the fact that you put work into these bikes to make them usable. A 100% markup (in total) might seem crazy but I am sure that you put more than $100 worth of labor into these not to mention the materials that you used. It’s like if I sold you raw wood and you milled it and built a house out of it. Then I came back and said you swindled me because you are selling my wood at a 1000% markup. It’s ridiculous! I’m sure you’ve already explained this to her but if not I would calmly do that (via message only) and if she can’t accept that she can kick rocks! Block her if necessary.

transaction happened, you put in the hours, so no problems here, if you just resold as it is then it's an ethics problem but you are not so I don't see an issue.

No not wrong at all. It’s life

I have bought a number of 90s mountain bikes and had the seller be miffed later when seeing the transformed bike. And I had given them a fair market price for our area for the too often unrideable bike at the sale. Only one pressed it and I did get to back off when I told him there was $300 in parts and 12 hours of labor; only the frame and fork remained of what he sold me for $100.

I think part of the choice of selling old stuff on facebook marketplace or other second hand platforms isn't to try and get as much money as you can out of it. It's about trying to find someone that can make use of it to give back to your local community. If I were to flip bikes or any other items on these platforms I would make my intentions to fix and sell clear to the seller. She might not know much about mechanics and think you haven't done anything to it. And to be frank you haven't replaced anything. Is a clean and tuneup with no replaced parts worth $50? What about the $50 bike you plan to sell for $200 too? If you're not spending more than a couple hours on each, can you really claim your work is worth 3x the price you bought it for?

You're not in the wrong at all. But, I don't think this bike is worth anywhere near $200 or even $175. At least not in my area. But it sounds like you've been doing this for a long time, and if there's a market for it then go for it.

Don't fret. I'm super liberal but it's easy to call out "free market" baby. It's called flipping. Lots of folks do it. Somethings worth as much as someone is willing to pay for it. You said it, if she'd have asked 400 for the two of them, you'd have said no way. Taylor swift this one and Shake it Off!
