The price of a custom bike will vary greatly based on what the customer is looking for. As expected, the more stuff that goes on the bike (braze-ons, lights, racks, fenders, etc.), the more it will cost. Polishing and custom fabrication will also make the price go up. I work with the customer on getting them a bike they can afford and will last them a lifetime.
This is a very general breakdown on what a bike will cost: As of July 2016, a custom frame and fork set starts at $2500, custom racks start at $325, and custom stems start at $300. Full component groups are available starting at $1500. For a free accurate quote, contact me. It never hurts to ask.
