E-bikes increase the frequency and duration of cycling compared to conventional bikes. •
Uptake of e-cycling largely substitutes for conventional cycling or private car journeys. •
E-bikes are primarily used for utilitarian purposes, with older adults also using e-bikes for recreation. •
E-cycling promotion campaigns should be guided by evidence on the purpose of e-cycling and factors associated with e-bike use. Conclusions
This review suggests that the personal use of e-bikes is associated with a reduction in motorized vehicle use, which has potential positive impacts on the environment and health. The impacts of e-bike share schemes and workplace initiatives are less well understood. Evidence describing the purposes for which e-bikes are used, and the factors associated with usage, are useful to inform e-cycling promotion policy.
