K-STAR is KED's own reflective technology for bike helmets. Retroreflective particles are embedded in the helmet's outer shell during the patented manufacturing process. When headlight beams hit the helmet, almost the entire surface becomes a brightly shining reflector with 360-degree visibility. Passive visibility that makes a real difference at dusk, in the dark and in city traffic.
K-STAR turns the helmet shell itself into a visible element. Instead of just adding a single reflector point, KED takes a large-scale approach: the reflective effect comes from the surface of the helmet, not just from a small add-on part.
For the rider, this means a much more prominent visibility effect, which is especially noticeable in road traffic. That makes K-STAR particularly interesting for riders who want to be not only safe but also clearly visible in everyday life.
K-STAR treats the helmet shell as a reflective surface, not as a carrier for an add-on element. That is the core of the technology.
The core of K-STAR lies in the material construction. Retroreflective particles are integrated into the patented manufacturing process before the helmet even takes its final shape. As a result, the reflective effect is not applied afterwards but firmly anchored in the construction. This integration makes the difference: K-STAR does not act like a single sticker, but like a component of the shell itself. This is exactly what creates the large-scale and lasting reflection logic for which KED positions the technology.
Retroreflection means that incoming light is not simply scattered diffusely, but is reflected back toward the light source. In road traffic, that is usually the headlights of other vehicles or bikes. When this light source hits K-STAR, the helmet surface appears far more visible. It is not an active light like an LED, but a highly effective passive visibility solution for everyday situations with changing light conditions.
A standard reflector is often just a small, clearly defined area. K-STAR goes further: the reflection is distributed across the helmet shell, making it visually and functionally far more present. That is what makes the technology so interesting for KED. It combines manufacturing expertise with visibility and delivers a solution that blends naturally into the helmet design.
A classic reflector is useful, but usually stays limited to one spot. K-STAR spreads the reflective effect across the shell, creating a much larger visible surface. So the difference lies not only in the look, but in the effect. K-STAR makes the whole helmet more visible, while a single reflector usually only highlights one point in the design.
LED lights are active and emit their own light. K-STAR works passively and needs no power source. Both have their place, but their tasks are different. An LED rear light is especially strong when active lighting is required. K-STAR, on the other hand, works whenever light hits the helmet. Combined, they create particularly strong visibility setups.
Fit systems provide fit, stability, and ease of use. K-STAR, by contrast, is a visibility technology. This matters because the two functions answer different questions. A good helmet needs both: a secure fit and a visible outward presence. That is why KED sensibly combines K-STAR with adjustment and comfort technologies instead of mixing up the tasks.
KED uses K-STAR in selected models, especially where everyday visibility is particularly important. The Meggy II K-Star is a kids' helmet with a full-surface reflector. Spiri II Trend, Rayzon and Citro are available in K-Star Pure color variants with retroreflective particles in the helmet shell.
One turn of the dial and the helmet sits. The fine adjustment works to the millimetre, one-handed, even while you ride.
The magnetic buckle closes with a click and opens with a single movement. It works one-handed and with gloves on.
The outer shell and the EPS fuse into one unit inside the mould. The result is light, seamless and dimensionally stable.
Reinforcing ribs in the EPS inner shell carry the load where the vents take material away. Plenty of airflow, no loss of stability.
The core of every helmet. The foamed inner shell absorbs the energy of an impact and spreads it over a large area.
