    Abstract:
    Although millions of electric bikes (E-bikes) operate in China and many associated deaths and injuries have been reported, E-bikers' on-road practices are poorly characterized and few direct observational studies have been performed. This study aims to describe riding behaviors among E-bikers and to investigate factors influencing these practices to inform injury prevention. In March 2012, a cross-sectional observational study was conducted at 14 randomly selected intersections in Suzhou during a 7-day period. A pro-forma observation checklist was used to collect data on road riding practice. Adjusted Odds Ratios (OR) and 95% Confidence Intervals (CI) to assess the likelihood of specific riding practices among E-bikers were evaluated using mixed-effects logistic regression. Among 18,150 E-bikers observed, 37.6% rode E-bikes with cycling pedals, 86.0% of E-bikes were registered, 26.6% did not comply with the road rules, and 41.1% wore at least one safety item. The overall prevalence of carrying passengers, riding in a motor vehicle lane, running red lights, riding in opposite directions (i.e., facing oncoming traffic), mobile phone use, and helmet use were 12.4% (95%CI: 11.9-12.9%), 1.9% (95%CI: 1.7-2.1%), 4.8% (95%CI: 4.5-5.1%), 3.4% (95%CI: 3.1-3.7%), 0.4% (95%CI: 0.3-0.5%), and 9.0% (95%CI: 8.5-9.4%), respectively. Male E-bikers was associated with increased helmet use and riding in motor vehicle lanes, whereas riding a registered E-bike was associated with reduced likelihood of carrying passengers. This study demonstrates common road rule violations and low helmet use among E-bikers and supports the urgent need to develop additional regulations and behavioral interventions to improve safety practice among E-bikers in China.
