OUr roots
Founded in 1854 as part of the Aug. Winkhaus GmbH & Co. KG, TRELOCK is based in Münster, Germany—one of Europe’s most bicycle-oriented cities. This environment shapes our perspective and drives our commitment to practical, rider-focused innovation.
Our engineers are cyclists themselves, bringing firsthand experience into every product we develop.
