Measuring the Efficiency of Off-Road Bicycle Suspension Systems

Off-Road bicycle suspension systems are beneficial because they dissipate vibrational energy and a lower vibration dosage can reduce the metabolic energy expenditure of the cyclist [1]. However, dampers dissipate energy and the energy dissipated must be compensated by additional input from the cyclist. Estimates of the energy dissipated range from 1–2% of the total power input by the cyclist [2–4]. Additionally, suspension systems add weight to a bicycle, which also requires additional energy when hill climbing and accelerating.
