The Leeze Development Principle
"The Leeze Development Principle"
Immerse yourself in our development, in which Prof. Eric Helter and his VR team combine pioneering virtual reality technologies with in-depth aerodynamics expertise. Innovative tools, including specially developed 3D scanners and VR goggles, enable the digital modeling of wheels in a virtual environment.
Thanks to the "Real-2-Digital" approach, we integrate real components precisely into our VR simulations. The result? Wheels that are not only aerodynamically optimized to the maximum, but also developed in a resource-saving way.
Our VR tools enable fast, cost-effective testing and produce wheels with a market-leading price/aero ratio. Experience the future of wheel development with Prof. Eric Helter and Leeze D2R!

VR glasses + controller
VR glasses, also known as head-mounted displays (HMDs), allow the user to immerse themselves in a virtual environment. They enable the user to interact in virtual reality by capturing hand movements and inputs.
Software for VR visualization
The in-house developed software enables engineers to import and manipulate the models captured with the 3D scanner into the virtual environment. The special features of this software include advanced rendering techniques, physically based simulations and special functions for collaboration in the virtual environment.
3D-Scanner
A 3D scanner is a device that can capture the spatial geometry of a physical object to create a three-dimensional model. The 3D scanner usually works by emitting laser beams or using structured light to capture the surface of the object and then converting this information into a digital 3D model.
Other tools and projectors
In addition to the tools mentioned, high-resolution projectors with corresponding lumen figures are used to project the virtual environment onto physical surfaces. These are used for group presentations or team collaboration.
Further insights into D2R development and optimisation
What characterises the D2R development
Simulating flow parameters, optimising wheel components
In the context of wheel development, the VR environment enables aerodynamics expert Prof. Eric Helter to comprehensively analyse a wide range of wheel configurations: Here, flow parameters are simulated and wheel components optimised.
The flow parameters simulated and visualised by Prof. Helter and his team in the VR environment (such as flow profiles and wind momentum effects) meet the digitally modelled wheel systems supplemented with 3D scans. Prof. Eric Helter can then evaluate the interaction of flow parameters and the wheel system in detail in order to draw conclusions about the necessary modification and optimisation of the wheel components (such as rim dimensions, spoke shapes or hub profiles).
Iterative variant analyses - Test and Learn
The focus here is clearly on iterative variant tests - quite simply because the VR development environment allows significantly faster and yet extremely precise variant tests compared to classic wind tunnel tests with physical models.
Advanced algorithms model wind forces on the wheels as well as the overall system on the wheel, wheel components and bike. This gradually creates a complete picture of the aerodynamic efficiency of various wheel configurations.

VR tools and aero expertise: the perfect symbiosis
Overall, the Leeze D2R development approach by Prof Eric Helter and his VR team represents a completely new and innovative use of VR technologies in the field of wheel development.
The symbiosis of VR tools and extensive aerodynamics expertise means that Leeze wheels can be developed not only extremely cost-efficiently, but also in a more resource-friendly way.
We pass this advantage on to our customers - with wheels whose price-aero ratio is market-leading and have been honoured with test wins in many wheel comparison tests.
Real to Digital
"Leeze CFD"
Fully digitally modeled wheel profiles are supplemented by precise 3D scans of real components. For example, real tire profiles from various manufacturers are scanned under different air pressure conditions and integrated into the VR environment as digital models by Prof. Helter's VR experts. These 3D scans are then incorporated into the aerodynamic tests and ensure that the real aerodynamic properties of the wheel systems can be predicted and optimized with extreme precision.
Advantages of D2R development
VR simulation and 360-degree visualization
The detailed and quasi-realistic 360-degree visualization of the wheel system in virtual space facilitates the evaluation and optimization of its aerodynamic properties, as flow profiles and wind momentum effects, for example, can be viewed in extremely high resolution and their effects in real use can be predicted so precisely.
The magnification of the wheel system in virtual reality knows no limits - this enables the deepest immersion in the wheel system for a thorough analysis. This makes it possible to determine exactly how the wheel behaves in different wind and flow profiles.
This can then be used to predict the real behavior of the impellers under a wide range of wind conditions. This realistic VR simulation makes it possible to make even more precise optimizations and efficiently test a wide variety of wheel configurations.
Resource-saving wheel development
The best price-performance ratio
Here too, our D2R development approach sets standards: the virtual prototypes modelled by Prof. Helter and his VR team drastically reduce the need for physical prototypes. Furthermore, we can almost completely dispense with costly and energy-intensive wind tunnel tests, which leads to an enormous reduction in material and energy consumption in our wheel development.
At the same time, the D2R approach allows us to accelerate development cycles, as iterative changes to the wheel profiles can be carried out in the virtual environment in a time and cost-efficient manner.
