The USB-C rechargeable Cateye Nano F combines impressive power with an extremely compact design. Delivering up to 100 lumens through the precision OptiCube lens, it ensures you are visible on the road — even in daylight. Weighing just 27 grams, the Nano F is almost unnoticeable on the handlebar, yet offers excellent visibility thanks to its six versatile lighting modes, including three Daytime HyperFlash options designed to stand out in traffic and the intense reflections of the urban environment.
