Identifying factors that predict riding without a helmet by e-bike delivery riders

Gig-economy delivery workers have an elevated risk of being involved in road traffic collisions. E-mobility is increasingly involved in delivery work, with e-bikes offering a relatively low-cost, easy and flexible mode of transport that supports earning an income. Evidence from local authority data shows that personal injury collisions involving e-mobility users has increased 25-fold from 2017 to 2023. However, relatively little is understood about the risk behaviours of delivery riders when using an e-bike for work.

Results of an initial behaviour survey identified riding without a helmet as a risky behaviour that delivery workers engage in frequently when riding an e-bike for work, with many riders reporting never wearing a helmet. A subsequent belief elicitation survey revealed perceived advantages and disadvantages, social approval and disapproval, and perceived likelihood of riding with and without a helmet while riding an e-bike for delivery work. A final study used a theory-based questionnaire to identify key psychological antecedents to delivery riders’ intentions to ride without a helmet when using an e-bike for work.

The study is part of a larger e-SAFE project (Equity, Social determinants, Anti-social behaviour, Future E-mobility), funded by the Road Safety Trust, which aims to better understand e-mobility road user behaviour. The presentation will focus on key findings from this work that can inform the design of effective safety interventions to increase helmet wearing among e-bike delivery workers in the absence of any policies or regulations regarding e-bike delivery worker safety.
