What Busch + Müller does

Busch + Müller (legal name: Busch & Müller KG) is a German family-owned manufacturer founded on 1 September 1925 in Meinerzhagen, North Rhine-Westphalia, by August Busch and Willy Müller. The company develops, designs, and produces lighting systems and rear-view mirrors for bicycles, e-bikes, S-Pedelecs, motorcycles, and mopeds, organised across two main product pillars: lighting (front lights, rear lights, indicators/turn signals, and reflectors in dynamo-, battery-, and e-bike-integrated variants) and mirrors (bicycle, e-bike, and motorcycle). The product portfolio includes the IXON battery headlight line, the IQ series (including the IQ-X 100 lux headlight), the Lumotec series, the Briq-XL digital curve lighting headlight, the TURNTEC T2 and T4 indicator systems, the Toplight Line Brex rear light with brake and emergency brake light, the E-Werk/K-Werk/USB-Werk dynamo power products, and manufacturer-specific motorcycle mirrors for BMW, KTM, Honda, Hercules, and MBK. The company holds numerous world firsts in two-wheeler lighting, several of which have been incorporated into German technical requirements (TA) under StVZO.

The business operates with high vertical integration at its 14,000 sqm Meinerzhagen facility (with a neighbouring site in Wiehl), including more than 30 injection moulding machines, an in-house galvanising plant, proprietary circuit board production, and a tooling library of more than 1,000 injection moulding tools. Revenue is generated primarily through hardware sales via four channels: a specialist bicycle retailer network across Germany and neighbouring European countries, direct-to-consumer sales through the BUMM online shop (bumm-shop.de) for spare parts and accessories, OEM supply to bicycle and e-bike manufacturers, and OEM supply to motorcycle and moped manufacturers (including BMW Motorrad since 1969). The company employs approximately 240 people, has been led by Managing Director Guido Müller and Senior Partner Dr. Rainer Müller since 1998, and holds DIN EN ISO 9001 (since 1997), DIN EN ISO 14001, StVZO, and E-mark certifications. All products are developed and produced exclusively in Germany.
