Custom bikes are works of personal expression and sometimes speculative ventures for exploitation of fad, too. A bike like the one you're contemplating defies assessment. Its parts might be worth several hundred dollars in the market, but that would be like determining the worth of a painting by the cost of its paint.
The market in LA is style-conscious. That bike ticks the style box. The seat even looks like it might be comfortable. A review of past eBay and Craigslist postings might give an idea. Just go ahead, buy it and enjoy it. What have you got to lose?
A Dolce & Gabbana dotted bow tie is $225, so this could well exceed that in practical value, comparatively. :giggles
