Bi Roller 2
The small and compact Bi Roller 2 has been meticulously designed for professional tandem flying in high wind conditions. There are two available sizes: 30 and 34 m2. It stands out for its easy take off in windy conditions, its high speed and damping. Reinvent your tandem flying experience with the Bi Roller 2!
Speed flying
The Bi Roller 2 is a mini wing with a very extensive speed range. Specially designed for speed flying, it is stable, light, manoeuvrable and can be flown quickly and precisely at all times.
Commercial tandem flights
A tandem wing designed to satisfy the most exacting professional dual pilots. Its durability and performance make this a glider that you will not want to part with.
Recreational flights
Experience a tandem wing as you never imagined it and let yourself be carried away by its supreme comfort and stability. Enjoy each flight with a tandem that adapts perfectly to your needs and those of your passenger.
3DL technology is an adjustment of the fabric at the leading edge of the wing to control the ballooning and the creases that are generated by the curvature in this area. The leading edge is then divided into sub-panels which are sewn into each of the cells at the front of the paraglider. As a result, the leading edge of the wing is perfectly tensioned, which benefits the wing in performance and durability.
A good comparison is a rugby ball. In order to produce its characteristic oval shape without creases, its cover is made of several panels – not of just one piece.
The application of this innovation, in conjunction with the 3DP, is key to converting the perfect shape from 2D to 3D.
The RAM Air Intake system is based on the inward orientation of the air inlets in the profile so that they allow an optimum internal pressure at all angles of attack.
The result? Having greater internal pressure means better buffering of turbulence, greater consistency of the profile shape across the speed range. Excellent handling at low speed is achieved by allowing the pilot to extend the braking limit, so there is a lower risk of collapse and consequently, greater control and stability.
This technology seeks to implement the best orientation of the cloth on each panel according to its location on the leading edge. If the cloth pattern is correctly aligned with the load axes, the cloth suffers less deformation flight after flight, so the leading edge maintains its shape better and remains stronger over time.
The design of our paraglider and paramotor wings has evolved a lot over the years, with a positive and specific focus on the leading edge.
Thanks to this technology and 3DL, a perfect modelling of the panels and an exact representation from 2D to 3D is achieved.
The ELS is a big ear locking system which provides a simple and effective solution for the tandem/dual pilot when quick descents are required.
Usually when the pilot has pulled big ears on a solo glider, they can only steer using weight-shift. Although it is also possible to do this with the help of a passenger on a tandem paraglider, in most cases this is insufficient. This is why Niviuk developed the ELS.
To use the Ear Lock System, simply pull the ear lock tab downward until the knot passes through the ELS (lock system). Then move them slightly horizontally forward, locking the knots in the V grooves. To release, pull the big ear tabs down to release the knots from the grooves. Then guide it vertically as it goes upward and back through the ELS. It is better to release the two ears asymmetrically.
Advantages of the ELS system:
- It enables the pilot to pull and release the ears as desired.
- It gives full steering control to the pilot with the ears applied.
- Lets the pilot use the ears as long as necessary with no physical effort at all.
- Allows the pilot to use the trimmers without concern or restriction.
- Prevents the ears from opening unintentionally, as they are blocked.
- The manoeuvre can still be performed the classic way, without using the ELS.
- Can be easily removed without affecting the rest of the equipment.
Nitinol is a combination of 50% nickel and 50% titanium. The incorporation of Nitinol rods in the profile increases the performance of the wing, especially in three areas:
- Compared to nylon rods, the weight of the wing is reduced by 13%.
- Nitinol has two essential characteristics: shape memory and enormous elasticity. As a result, the rods retain their optimum shape even after an ultra-compact or incorrect folding, so that the wing is not deformed. This will always be the case unless the radius at the point of curvature is less than 1 cm.
- The leading edge shape is much more rigid and uniform which results in a much more consistent and progressive inflation and therefore an easier take off. The profile is taut at all times, without creases, and fully optimised for all flight phases.
In addition, the rods have a plastic protector at their ends to prevent any damage to the fabric of the wing.
Nitinol is now featured in all our wings.
