Best bike lights in Groningen 2026

Groningen is the cycling capital of Europe: roughly 60% of all trips are made by bike, and in winter months (November to February) it's already dark by 16:30. The combination of long dark evenings, open Ommelanden wind, and the student population commuting between the city and Zernike campus makes proper lighting crucial. On the Zernike route, Eikenlaan and around Grote Markt, police have been running targeted checks since 2021 during the dark months; the fine is 65 euros. Northerly winds bring horizontal rain and fog in from the Wadden Sea, and on the open route between Paddepoel and Zernike a 15-lux lamp literally vanishes in the fog. Groningen students often choose USB lights from Knog or Lezyne (cheap and portable), but for serious commuters and the classic Groningen omafietsen a Shimano or SON hub dynamo is standard. For e-bikes the Busch & Müller IQ-XS is a common pick. Given the open windswept plains to the north, a clear output of at least 40 lux is advisable.
