I'm thinking about offering bicycle repair in my rather blue collar, heavily latino neighborhood. Most are the dreaded big box store brands. Also, lots of BMX bikes around here. Is it worth going through on trash day and trying to flip any of them?

Looking for your thoughts and perspective on this.

I mostly lurk here so go easy on me about the fact that these bikes aren't worth repairing okay? For some of these folks, spending $20 for a new chain plus labor is more affordable than spending $99 for a new one.

Thanks in advance
