im a college student and i was thinking about buying used road bikes from people that are selling them cheap and then tuning them up to resell. does that sound profitable? just out of curiosity i bought a giant tcr carbon frame bike for $600 from an old guy who bought it for over 1k and couldn't ride because of back pains so it was a "my loss your gain" deal. I flipped it and made $200 in 24hrs easy. so im wondering if i should flip bikes for some extra side income. anyone done this before? i just got my biz license and my local city hall says i can operate as a home based business out of my apartment,
