The V521s headlamp is a good example of Supernova's continuous development. Based on the housing of the popular V6, the electronics have been completely redeveloped. Now voltages of up to 21 volts can be processed. A special highlight is the soft start function, which makes the headlight compatible even with those drives that react sensitively to high starting currents. At the same time, this improves the service life and brightness stability of the LED light source. The front light does not have a switch. Instead, it is conveniently operated via the e-bike's control unit.

The V521s is equipped with Automotive Power LEDs and a Terraflux 2 lens, which gives you the necessary attention in road traffic even in adverse conditions. At night, this combination guarantees optimal, uniform illumination in front of the bike, but also excellent illumination of the surroundings.

Terraflux lens and daytime running light
The Terraflux lens is a milestone in optical development. No other lens of this size produces such bright and uniform illumination on the road and at the same time has such good ambient illumination above the cut-off line. With the Terraflux lens, you are noticed in traffic and yet not dazzling oncoming traffic. Thanks to sophisticated light control, the Terraflux lens directs 90% of the light to where it is most needed : onto the road. There it forms a broad and even carpet of light that reaches from the front wheel far into the distance. The permanent daytime running light integrated into the lens ensures very good visibility of the rider in traffic during daytime. At night, this light component is used for excellent ambient illumination and warns of low-hanging branches on the trail.


Optical precision
"The German-made Terraflux lenses and M99 Matrix reflectors are the products of years of research and development - true masterpieces of engineering! The quality of a headlamp stands or falls with the quality of its optical elements. That's why we invest a lot in perfecting these key components. Our developers meticulously evaluate thousands of computer simulations to create optical systems with the best possible light pattern. Only high-purity materials are used in manufacturing and the final quality is controlled with microscopic precision."

Tested beyond the norm
"With us, you can be sure that you will reach your destination safely. Our light systems will not let you down, whether in everyday life or in extraordinary situations. To do this, we go beyond the standard tests that are common in the cycling industry and simulate even the most adverse conditions, so that no matter how, where or when, you can always count on your Supernova product. Every year we develop more demanding and tougher tests to make our products even more robust. The bottom line is that our lighting systems are not only powerful, but also efficient and high quality."

"The issue of sustainability is one of the most important pillars of our company. Protecting the environment is very close to our hearts. Our core values are based on this and are an integral part of everything we do. We strive to make today's earth and that of our children a better and cleaner place. By trying to encourage people to cycle and by making it more attractive and safer through our products, we want to promote sustainability and contribute to a better future. Our goal is to inspire our colleagues, friends, customers and business partners to follow our example. It is also important to be creative and realise every optimisation. Every contribution counts!"
