More about Peak 4
The Peak 4 is a pure breed XC wing, ready to bridge the pleasure of flying one step closer to reality by bringing inspired confidence with your emotional response in every flight.
As an authentic XC, the glider was designed to challenge and bring out the adventurer in you. Enjoy maximum performance in each flight. Be in charge by fully and precisely controlling a superb wing able to carry you to the four corners of the world.
Fly hundreds of kilometers under a fast two liner, stable at any speed, and designed for long routes. Easy to manage and understand, with an excellent sink rate or climb in thermals. Maximum performance for experienced pilots, but with an accessibility level never seen in its category.
Through its veins runs the DNA of a world champion, the Icepeak 6, and equipped with the best features and latest technological innovations found with today's gliders. Nitinol, to name one, is part of its internal structure, giving a uniform profile design to the wing while keeping the initial performance level intact but reducing the overall weight.
From the glider turning dreams to reality, the PEAK 4 was then born. Intense, exciting, built for adventure, and with an insatiable appetite for kilometers, it has an enormous potential for endless exploration anywhere on the planet. Peak 4, the Cross Country spirited wing.
SLE (Structured Leading Edge)
The SLE provides more rigidity and stability along the span of leading edge but also allows full flexibility along the both the vertical and horizontal axis of each open cell. The SLE ensures ease of movement on the ground and high security in the air during turbulence and whilst flying at speed.
With the SLE system there is no longer a need to use large amounts of mylar material to achieve leading edge reinforcement. This reduction in material has reduced the weight of the leading edge and the result is precise handling on the ground and easier launches.
The SLE also helps to prevent deformation of the leading edge and therefore with correct care will extend the life and efficiency of your glider.
In addition to the SLE, we work on new geometry and layout of the internal reinforcement. This new internal restructuring offers better overall cohesion of the glider and incredible stability during turbulence.
TNT (Titanium technology)
Constantly innovating, we always are on the hunt, looking for the latest and best materials to helps us design optimal products. For this reason, and after an extensive evaluation of its benefits and qualities, we decided to be the first manufacturer to use Nitinol in our glider line.
Nitinol is an alloy of 50% nickel and 50% titanium. This technology in our rods offers three major advantages of optimizing the performance of a paraglider, compared to those made out of Nylon:
- The addition of Nitinol rods in the profile has the immediate result of substantially reducing the overall weight of the wing by about 13%.
- Nitinol has two very specific properties: shape memory and super elasticity. The flexible rods always regain their functional optimal shape, even after tight bending, no wrinkles or residual mechanical alterations affect their integrity.
- As a result, the wing's leading edge is then preformed on the ground and allows a uniform progressive inflation phase to take place, which considerably facilitates the take-off. The wing surface is perfectly taut, wrinkle free and without parasitic cloth movements, the glide is thus optimized in all flight phases.
In addition, the rods are outfitted with plastic protectors at their ends to prevent fabric damage.
STE (Structured Trailing Edge)
STE is based on the curtting edge technology we use for our competition wings. It optimises the profile without deforming it. We can thus obtain less resistance and better performance. With the STE, the circulation of the air is more fluid, maintaining a consistent airflow at the trailing edge, and obtaining a cleaner airflow at high speeds. When we reduce the speed of the wing, it is its entire surface which slowly starts to bend, not only its trailing edge, as happens with the wings that do not have STE. The pitch control is notably improved as well. When in flight we accelerate the wing, its profile keeps more balanced, giving to the wing more stability, especially in the trailing edge. STE works on more surface of the wing without distorting the profile. STE: state of the art technology applied to Niviuk serial wings.
DRS (Drag Reduction Structure)
The trailing edge has been reinforced with small ribs that make this part flatter in order to spread the pressure out evenly. It means better air-flow and less drag on this important part of the glider. The addition of these ribs gives the glider exceptional handling (better and more efficient when turning) and more control and precision.
3DL (3D Leading Edge)
Adding an extra seam to the leading edge on the span axis of the glider helps to shape a compact 3D profile and have better connections to the new 3DP front panel’s layout.
When sewn together, the fabric pattern orientation and panel positioning are taken into account to avoid creases and ultimately obtain a perfect load distribution. As a result the glider profile is cleaner, to the benefit of performance and durability.
The application of this innovation to the profile is key to reaching the perfect shape from 2D to 3D.
3DP (3D Pattern Cut Optimisation)
Our paragliding and paramotor wing designs have changed significantly over time; hence considerably affecting the leading edge shape.
The latest glider generation requires a new pattern design and an optimized fabric cutting process.
The new leading edge arrangement calls for each cell panel to be manufactured independently from the others according to the final wing layout positioning, resulting in a crease-free surface with better fabric tension. We could use the analogy of a rugby ball made of different sewn individually shaped panels to obtain the perfect characteristic oval shape without wrinkles.
An optimised process is used to cut the fabric in a specific directional angle, depending on each panel’s final location. If the cloth pattern is correctly aligned with the load axis, the material is deformed to a minor degree to benefit the aerodynamic properties of the leading edge.
The application of this innovation, together with the 3DL, is key for reaching the optimal modelled form and function from 2D to 3D.
RAM Air Intake
Evolution and constant improving in all our products is the essence of the DNA of Niviuk’s R&D team. Thanks to the new technologies created over recent years, we have conceived new and more evolved and higher performing gliders. In this context the RAM Air Intake technology should be pointed out.
The evolution of RAM Air Intake
The RAM provides optimised internal pressure for better airflow; therefore, the glider is more compact at any angle of incidence and all trim settings. It reduces the risk of experiencing a collapse while bringing better control and stability to the overall structure. Moreover, the RAM improves the wing’s turbulence buffering ability.
Technology, a priority for Niviuk
For us, giving importance to small details means continuing working towards our goal. It means keeping focused on technology as a priority. It means provide innovation and quality to all pilots.

Niviuk Peak 4 reviews
Parapente + tests the Peak 4: "The Peak 4 is a superb high performance purebred XC glider. The figures given here may be fanciful, but we honestly never published nor held such high praising values for a serial wing before". That’s what Jean-Michel Ara-Somohano wrote after evaluating the Peak 4 for Parapente +. After flying it for over twenty five hours in a month time and in all kinds of weather conditions, the pilot discovered and explained the close relationship in performance and comfort similarities between the Peak 4 and a competition model. He added that the high Cross Country potential ability of the Peak 4 is due to combining factors of manoeuvrability, safety, solidity in thermal and turbulent air. Ideally suited for long flights, it will please enthused pilots eager to devour long distances for hour on end. Download the full review (PDF, French).
Tim Rochas: "I flew a week with this new Peak 4 and I'm totally in love! It's very simple, like a toy! It looks like my Icepeak 8, but in very simple! The turning is... Whaou! Very, very pleasant! It inspires a sensation of security from the first minutes of flight and you feel immediately that you have a performant glider! I'm in love! Nice job NK R&D!"
Eric Pusiol: "I only fly Cross-Country and in national competitions. The transition from the Artik 4 to the Peak 4 is very natural. The Peak 4 inflates easily and effortlessly. Its turning behaviour is light and precise in spite of its aspect ratio. The gliding sensation immediately indicates the change of category, and steering the wing using the "B" lines is truly efficient. And what surprised me the most was the overall efficiency of the wing, from speed, gliding, climbing in thermals, and especially its accessibility to use and take advantage of all those high-level performance features when needed."
Kari Ellis: "The Peak 4 arrived and I had my first flights on it on the weekend in the Aussie flatlands. What an amazing glider! I am very happy! I flew 206km on Saturday and 351km on Monday. I am flying the size 23 and for my taste it flies beautifully with amazing handling at 100kg TOW - heavily loaded enough to be nicely pressurised so it feels solid and allows good authority in the turn in rough/strong lift and wind, without compromising my ability to get the desperately low saves or seek out the light conditions at the very end of the day. I had a couple of asymmetries in the strongest peak of the day and the glider was very well behaved in recovery. Very easy to launch in the windy tow paddock."
Vincent Perlbarg: "I had planned to take it easy with Cross Country flying this season and to be honest not buy another wing. Then, I took the Peak 4 for a spin… The "B" in hands and speed-bar under my feet, piloting became exhilarating. It glides, it is fast and always remains perfectly under control… we must admit that 2 liners are from another world and the Peak 4 let us discover it. It is true accessible performance!"
