Construction of Stephanie Zundel’s unique tandem track bike is underway under the guidance and direction of Coach Brian Abers of BriHOP Coaching. The precise bike position and fit measurements were honed by Robert Mayfield of Bike COS Mobile. These were then handed off to Don Walker Cycles to develop a hand built, steel frame with custom geometry. As the “tiniest track tandem ever built,” this extremely stiff and responsive bike promises to deliver maximum efficiency while exemplifying beautiful craftsmanship through the skilled builders at Don Walker Cycles. As founder and president of NAHBS, the North American Handmade Bicycle Show, Don Walker brings decades of experience hand building bicycles to fruition.
