Since more than 160 years, TRELOCK has been offering quality,
innovation, safety and security for cyclists and their bicycles.


TRELOCK is a traditional brand from Münster – the "bicycle capital" of Germany. It is one of the oldest German accessory brands and one of the most well-known in the bicycle sector - in fact it is a brand every fourth cyclist in Germany is aware of. Besides, over the past ten years, TRELOCK has been able to double its brand awareness (GfK survey 2015).

Our customers are at the focus of our actions. At the same time, the TRELOCK team is committed to the tradition of the brand and takes innovation in the field of bicycle locks, lighting and displays very seriously – today and in future for the benefit of cyclists in many countries of the world. With the know-how gathered over more than 160 years, TRELOCK stands for high-quality and reliable products for international markets – and since 2015 we have also returned to Germany.

Since 2016 TRELOCK is part of the Allegion family of brands.

In its history that spans more than 160 years, TRELOCK has always stood for trust and technical expertise and tied its customers and partners all over the world to its international brand through fascinating products offering reliable function and tested quality – and will continue to do so in future.
