Small, smaller, mu – The developers couldn’t give the tiny B+M µ Mini dynamo tail light a better name than mu. With a diameter of only 19 mm, the luminous gnome is as small as a 2 euro cent coin and yet, the light with a discreet aluminium housing impresses with high light power and great lateral visibility. A road legal micro rear light that provides high visibility in road traffic could hardly be more minimalist. The elegant high-quality tail light goes perfectly together with beautiful design front lights for dynamo operation like the IQ-X (e.g. product code: 2165781). Once fitted to the mudguard or seatpost with the appropriate bracket, the tiny light button perfectly blends in with the overall look of your bike. Yet, the smart µ rear light by B+M impresses with enormous light power and can definitely keep up with the big lights.

Mu Mini Rear Dynamo Light

Das Rücklicht ist winzig, aber trotzdem unübersehbar hell.

Sehr empfehlenswert!

Gefällt sehr gut, top Qualität, wenn auch etwas teurer.
