SIMULATION IN THE development process
All components of our cyfly drive and/or of our bicycles have been calculated in elaborate simulation procedures at workstations. The latest software tools, such as ANSYS classic, are used in this. Individual load cases are simulated in complex multiple-body simulations. This way, possible weak points can already be localised during the development of components. Our simulation models are based on genuine load cases, such as, for example, pedalling while standing or jumping from kerb edges with the bicycle. We have calculated these in elaborate trials using the most modern measuring procedures. These real load case are part of every simulation as so-called boundary conditions. This ensures we have a perfect basis for simulations for future further and new developments. Thanks to this method, adopted from automobile manufacture, we shorten the development times of future bicycle and drive models to a minimum.
FEM CALCULATION AND MULTIPLE BODY SIMULATION
MODERN PROCEDURES FOR THE USE OF HIGH-PERFORMANCE MATERIALS
Individual components of the cyfly drive such as e.g. the crank and the interface at the frame are forged from high-performance materials such as 7075 and/or 7020 aluminium.
The challenge in the forging of our components consisted of the very high degrees of forming with at the same time high-strength aluminium materials. This means that from the blank to the forged final product, the shape differences are relatively large. Thanks to the expertise of our engineers and our development partner we were able to overcome these challenges and develop forging tools suitable for series production. These make it possible to manufacture high-strength, complex components with very high design requirements.
All aluminium components of the cyfly drive are in addition anodised after the forging process to protect against oxidation and mechanical damage. The surface of the cyfly crank is laser-engraved in the final step. In this step the lettering is also sealed with an oxidation layer.
AIRBRUSHING AND PAINTING BY HAND
The premium painting of Möve franklin is given an elaborate colouring. In the first step, a colour gradient is applied by hand, alternatively between white and grey and/or black and grey. In the second step, the special interference pattern is applied by airbrush. The pattern resembles the feathers of a seagull, Möwe in German, as a reference to the company's name. The resulting unique artwork is sealed in the last step at approx. 180°C with a high-strength powder coating consisting of matt clear powder.
The bag holder made of seamlessly drawn stainless steel, specially developed by us for the Möve franklin, combines integrative design with full-range function.
The bag holder rests on the aluminium hollow-chamber profile mudguard in the front area, which means that it is designed for high loads.
In the equipping of our bicycles we pay attention to the choice of components. Quality, durability and functionality are the criteria we prioritise in this. For example, we install the SON hub dynamo, the Rohloff Speedhub hub gears, and brakes of the Shimano XT series as standard.
INTEGRATED CABLE ROUTING
On the Möve franklin XT the Bowden cables and the electrical cables are laid inside the frame. To protect the external areas, we coat every Bowden cable again with a safety mesh tried and tested in automobile manufacture.
DOUBLE-CHECK PRINCIPLE IN THE PRODUCTION PROCESS
Each component and every screw joint is tested by us several times. Only in this way can we ensure that every Möve bicycle leaves production with the high quality that we want. This prevents safety defects and unattractive finish.
Another special feature at Möve is the fine adjustment of all mobile and adjustable components. For example, we already set the breaks and gearshift ex works. Beyond this, the brakes are all broken in. This prevents irritating grinding noises or squeaking of the brakes.
Every Möve bicycle therefore reaches you in perfect and ready-to-ride condition in the safety transport packaging developed by us.
CYFLY – LIKE A SWISS WATCH
A WORK OF ENGINEERING ART
The cyfly drive consists of just under 100 individual parts, which are produced in Germany. Each component is tested for dimensional accuracy before single user installation. After testing, the single parts are installed to form assemblies on devices specially developed for them. Each assembly is tested for its part function before further processing.
After this the assemblies are fully fitted together to form the complete cyfly drive. Each cyfly drive then receives its numbering and is connected to the completed bicycle.
