Introduction

Electrically assisted bicycles (e-bikes) have become increasingly popular in the past decade. This review aimed to scope the literature to identify what is known about the frequency and duration of e-bike use, their impact on travel behaviour, the purposes for which e-bikes are used and factors associated with e-bike use. In addition, the review aimed to identify gaps in the literature and highlight future research priorities.

Methods

A scoping review of published and unpublished literature in any language. Relevant articles were identified through searching six databases, two grey literature platforms and reference lists. Searches were conducted until August 2019. Data were extracted using a standardised extraction form and descriptive and narrative results are provided.

Results

Seventy-six studies met the inclusion criteria. The volume of research has increased since 2017 and primarily examines personal e-bike use, as opposed to e-bike share/rental schemes or organizational e-bike initiatives. The use of e-bikes increased the frequency and duration of cycling compared to conventional cycling and may help overcome barriers associated with conventional cycling. The uptake in e-cycling largely substitutes for conventional cycling or private car journeys, though the degree of substitution depends on the primary transport mode prior to e-bike acquisition. E-bikes are primarily used for utilitarian reasons, though older adults also engage in recreational e-cycling. Research priorities include quantitatively examining e-bike use, their impact on overall transport behaviour and identifying determinants of e-cycling to inform intervention and policy.

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.

电动自行车对旅行行为的影响：范围审查。

介绍

电动助力自行车（电动自行车）在过去十年中变得越来越流行。本综述旨在确定文献范围，以确定有关电动自行车使用频率和持续时间的已知信息、它们对旅行行为的影响、使用电动自行车的目的以及与使用电动自行车相关的因素。此外，该审查旨在确定文献中的空白并突出未来的研究重点。

方法

以任何语言对已发表和未发表的文献进行范围审查。通过搜索六个数据库、两个灰色文献平台和参考文献列表，确定了相关文章。搜索一直持续到 2019 年 8 月。使用标准化提取表格提取数据，并提供描述性和叙述性结果。

结果

76 项研究符合纳入标准。自 2017 年以来，研究量有所增加，主要研究个人电动自行车的使用，而不是电动自行车共享/租赁计划或组织电动自行车计划。与传统自行车相比，电动自行车的使用增加了自行车的频率和持续时间，并可能有助于克服与​​传统自行车相关的障碍。电动自行车的普及在很大程度上替代了传统的自行车或私家车出行，尽管替代程度取决于购买电动自行车之前的主要交通方式。电动自行车主要用于实用目的，尽管老年人也从事休闲电动自行车。研究重点包括定量检查电动自行车的使用，

结论

该审查表明，个人使用电动自行车与减少机动车辆的使用有关，这对环境和健康具有潜在的积极影响。电动自行车共享计划和工作场所倡议的影响不太清楚。描述使用电动自行车的目的的证据，以及与使用相关的因素，有助于为电动自行车推广政策提供信息。
