Abstract
This study examines the influence of handlebar geometry on the vibration characteristics of disaster- resistant bicycles equipped with puncture-resistant tires, which are known to increase vibration and reduce comfort. Three handlebar types—straight, riser, and bullhorn—were evaluated through impulse hammer excitation and acceleration data analysis under controlled conditions. The results showed clear differences in vibration transmission depending on handlebar shape. Notably, the bullhorn handlebar exhibited superior vibration dispersion and lower peak acceleration values compared to the straight and riser types. These findings indicate that handlebar geometry significantly affects vibration characteristics; however, further investigation is required to directly assess improvements in ride comfort.
