616 Bicycle Fabrication

616 Bicycle Fabrication We’re a bicycle fabricator with decades of experience building fat-tire, mountain & tandem bikes. 616 is the area code for West Michigan. See you on the trail.

We chose this as part of our name because of our love of the area, the local riders, and to honor such a great place that holds bicycling so highly regarded. This area is also the birth place of two cult like bicycle companies who have been in business for decades, Slingshot Bicycle Co. and Nukeproof Mountain Bikes. In July of 2011, the former owners of these two companies joined forces to bring t

he best custom hand built bicycles and hubs to the biking industry, and 616 Fabrication was born. Here at 616 everything we produce is manufactured right in our facility or locally made. Our goal is to utilize the best resources, people, and talent that West Michigan has to offer in an effort to produce some of the most progressive, detailed, and best riding hand built custom bicycles and hubs on the market today.
