The height-adjustable stem and adjustable seatpost, both with flip-flop length adjustment, mean that the seat position of the Birdy can be adjusted to rider heights from 1.50 to 1.95 m and adapt to every rider’s comfort preferences. As a result, it can be used by multiple riders. The large diameter of the stem and handlebars, as well as the quadruple clamp, ensure maximum rigidity and stability.
