The geometry of a frame is crucial for the riding experience. The demands are different depending on the different categories. Seeking for the best performance a rider wants to achieve maximum power output and needs a riding position which supports a special incline of the hip and enables all needed muscles to work together. A leisure cyclist riding on a touring bike needs comfort and wants to arrive relaxed. Seat height, top tube length, width of the handlebar and backsweep and upsweep must be adapted accordingly so that the angle between hip and back is healthy and comfortable. To be in control of all these aspects in a very early stadium of our development we built a geomtrey bicycle. Using this universal machine we can measure, check out and improve the geometry for different riding situations. Of importance is also the influence of components like handlebar, stem, seatpost, saddle and crank and is part of our testing.
Since several years we rely on our inhouse testing done in our own test lab which is beeing updated all the time. We measure the stress factors for a bicycle while being ridden. To get visible results out of the physics we use different sensors e.g. for acceleration positioned at the frame and the axles, travel measuring at the suspension elements and strain gauges at different places of the frame to detect the deformation of the tubes. Using our test machines we can calibrate our testbikes to deduct the forces and torque existing under real life conditions. All the data are saved and stored on a mass storage device and can be read and analyzed after the test ride. Because human riders can’t reproduce every ride with 100 % a camera films everything so we can see the part of the test course and can detect differing influences to the measured values.
Developing our products this testing delivers great advantages because we can simulate the stress even before building the first prototypes using the Finite Element Analysis software. All of our testing machines try to simulate real life as close as possible to ensure a maximum of safety and quality. The data of our real life testing are applied to the test lab, too.
