Instrumented Bicycle for Experimental Investigation of Braking Dynamics including Front Brake induced Rear Wheel Lift Up

An instrumented bicycle equipped with sensors measuring variables of motion including absolute over ground velocity and attitude is presented. Relevant design parameters are measured including geometric parameters, inertia values, suspension parameters, and tire characteristics. A multibody simulation is set up and validated. The bicycle is used to investigate brake induced pitch-over motion in detail. Robust indicators of rear wheel ground contact loss are identified.
