Over Twotone Amsterdam

The roots of Twotone go back in 2007, when Twotone’s founder – Jon Woodroof – cofounded a fixed-gear focused bike shop in Atlanta, GA named No Brakes. His clothes nearly always matched his track bike & he earned the nickname Twotone. Jon cut his teeth on promoting his own shop, the brands they sold, and even suppliers, athletes, and other organisations they partnered with all before Instagram!

Those entrepreneurial roots grew into the hold your line, you'll be fine full-send approach to how we run our business today. A 10-year-old nickname became a Dutch BV in 2014 & Twotone has become THE one-stop-shop for cycling-savvy sales, marketing, and PR across Europe in the USA.

Over the course of the past nearly 9 years of helping brands find their way & have their say, we’re grateful for the successes, lessons, and trust! Schedule a meeting to learn more!
