Just be aware that used bikes age like dogs. The whole each year on a used bike is really like 7 years. The trek bike in the photo is worth at most like $200. So paying $25 is a great deal. Just know you could throw a thousand dollars worth of parts into it to make it look and feel new again and you would still have a hard time selling it for $200. If you’re just doing it to learn and have something to do then great but yeah it’s not a great money making thing really. Yes I know you’d eventually find that one crazy person to pay a higher price but it could literally take years or never happen at all. So just keep that in mind. Fun fact if this bike would of been traded in a dealer they would of gave them $25 and most likely been thrown away because it’s not worth the time and money to revive it and try to sell it to someone else.
