Performance testing for two-wheelers
A budding machine construction technician from the Grundig Akademie in Nuremberg has constructed a performance test stand which determines the performance using a mass inertia roller. The perfomance test stand for motor bikes and mopeds up to 125cm³ can be built flush with the floor so that the space can be used when the test stand is not in used.
To determine the motor performance, a roller with high mass inertia is driven by the wheel of the vehicle being tested while the motor is accelerated over the entire rpm range. Simultaneously, the rpm of the roller and motor are measured and recorded so that a software can later calculate and display the performance curve. (Image 13)

The test stand must be functional for all conventional mopeds/motorbikes up to 125 cm³. A variable front-wheel mount must be provided for securing the vehicle. As the rear wheel of the vehicle being measured is positioned over the centre of the inertia roller axle, the front-wheel mount must be infinitely adjustable in the longitudinal axis. Thanks to the variable adjustment with locking mechanism via a cam clamp (10500). (Image 5)

The inertia roller is installed flush with the floor so that the floor space can be used when the test stand is not in use A floor plate with hatch was designed to cover it. The floor plate is fstened together with the hoist rings (07772), which are intended for securing the vehicle. The hoist rings were arranged symmetrically to the inertia roller to ensure that the vehicle is secured evenly. (Figure 7)
