ReBcycle carries a variety of cool handmade products made from used bicycle parts, including Beer View Mirrors and Soda View Mirrors (for bicycling or rowing) and keychains, magnets, and ornaments made from used bicycle chain. The mirrors can be made to attach to glasses/sunglasses, helmets, or baseball hats. During a break in between jobs as a bicycle planner in 2013, Patrick McMahon decided to finally get around to making some cool stuff out of the used bottle caps and bicycle parts that he had around the house and was able to get from the recycling bins of local Baltimore bike shops. Over time, ReBcycle has grown and evolved with Etsy sales throughout the US and to several other countries, participation in Made in Baltimore pop-ups and online stores, and occasional craft fairs around Maryland.
