“The BYB is the culmination of four years of focused work by the team,” stated Josh Hon, Tern Team Captain. “We had to develop some radically new technology for this bike and the manufacturing tolerances are, in the words of our factory partner, ‘tighter than automotive’. But we’re excited because new folding bike paradigms only come along every few decades or so, and we think the BYB falls into that milestone category.”
