I used a few different methods to market my product to my target audience.
For Fuse, I used the postcards that we created with a sticker of my logotype, and a small description of my product. If the cards format had not been predetermined, I would have opted to use a photo instead of a tagline or description. Conrad is hard to comprehend to those that have never had it explained to them, or see it in person. I have also been alerting my friends of the sale of Conrad through Facebook. I set up a small promotional picture-based piece to set as my default profile picture. This way, anyone who I may cross digital paths with may stumble upon my picture, click to enlarge it, and be further informed by information that I set as the pictures caption.
Another technique, and the most successful thus far, was to post a small introduction to my product in popular cycling forums like Bikeforums, which is filled with any kind of cyclist imaginable, and also TrickTrack, which is a community of Fixed Freestyle riders. I included a link to my online store on Big Cartel, a place to sell handmade goods for free, so that they could buy the products themselves. This helped me sell off the rest of my initial designs, and generate extra capitol to buy materials in bulk to save money. Other online venues include fixed gear enthusiast blog sites such as Locked Cog, and Prolly is not Probably. Conrad has even made his way overseas thanks to a site called HotOneTen, based in England as well as Trackosaurus Rex of Australia. I have also approached some local shops in hopes of making some kind of arrangement for them to carry my product. Until that materializes, I will continue to sell and promote online. It's free, and it allows me to reach a larger concentration of my target market.
