The impact scenarios, impact velocity were investigated based on 224 car-electric bicycle collision cases in IVAC (In-depth Investigation of Car Accident in Changsha) database. Cars were classified into three types: sedan, SUV and one box. According to analysis of traffic accident data, car-electric bicycle collision models were built up by using MADYMO. In order to analyze the kinematics of electric-bicycle-riders, this paper conducted a series of numerical experiments by changing the types of cars. Results show that the most prominent impact modes were frontal impact (54%) and side impact (33%), rider's head tend to strike sedan at upper part of the windscreen', 'SUV at the front end of bonnet, and one box at lower part of the windscreen, The peak values of head's and pelvis' acceleration were higher and occurred earlier when a SUV or one box impacted with electric bicycle.
