There is a butt for every seat. He is probably tagging an untapped market in his local area and will likely be successful. He is simply sourcing parts and building “his bike”. Not uncommon. This is where many riders, myself included, got started. My first was a BD bike from motobecane. It didn’t murder my budget and allowed me to learn at a minimal cost of entry and learn to work on my own stuff. I still have the bike and thrash it regularly. However I see your point. It Ingenuity and innovation are very expensive. I bet he gets an A I. His marketing class though!
