To address the negative effects of car use, conventional and electric bicycles are often proposed as environment-friendly alternatives. The aim of this research is to identify the prospects of a modal shift towards conventional and electric bicycles based on a case study analysing the mobility generated by the three main campuses of the University of Liège in Belgium. In the theoretical part of this paper, the known factors and strategies that affect most of the bicycle use in Europe are summarised and the need for a deeper understanding of the elements that promote a modal shift from bus and car users to the use of electric bicycles is highlighted. Consequently, the results of a survey conducted among the university population of the University of Liège(students, PhD students, and staff members; including 1496 questionnaire responses)are presented and analysed in detail. The Net Promoter Score (NPS), as an indicator of the user satisfaction, confirms that the bicycle has the best NPS compared with the main modes of transport (car and bus) and that the electric bicyclehas a greater NPS than the conventional bicycle. The importance of many factors affecting the use of cycling is lower if we consider the electric bicycleinstead of the conventional bicycle. Considering the current travel patterns in terms of the distances travelled, the potential for the use of conventional bicycles only reaches 23% of the university users, whereas that of electric bicycles reaches 70%. In the pursuit of a modal report, the most imminent factor is the development of safe bike paths, where a potential increase in the bicycle use is acknowledged by 74% of the students, 62% of the staff members, 62% of the car users, and 82% of the bus users. Finally, because the lack of safe cycle lanes remains the major obstacle with respect to the use of both bicycle types, the development and/or improvement of a comfortable and secure infrastructure for cyclists within a radius of 12 km from the main school and work places, especially in the main residential and commercial areas, should be prioritised to promote the use of both types of bicycles.

为了解决汽车使用的负面影响，通常建议将常规自行车和电动自行车作为环境友好的替代品。这项研究的目的是通过案例分析比利时列日大学三个主要校区产生的机动性，确定向传统和电动自行车模式转变的前景。在本文的理论部分中，总结了影响欧洲大多数自行车使用的已知因素和策略，并且需要更深入地了解促使从公交车和汽车使用者向电动自行车的使用方式转变的要素突出显示。因此，对列日大学的大学群体（学生，博士生和工作人员）进行的调查结果；包括1496份问卷调查问卷）进行了详细分析。净使用者评分（NPS）作为用户满意度的指标，证实了与主要运输方式（汽车和公共汽车）相比，自行车具有最佳的NPS，并且电动自行车的NPS比常规自行车更高。如果我们考虑使用电动自行车而不是传统自行车，那么影响骑自行车使用的许多因素的重要性就会降低。考虑到当前的行驶方式，从行驶距离来看，使用传统自行车的潜力仅达到大学用户的23％，而电动自行车的潜力则达到70％。在追求模式报告时，最紧迫的因素是安全自行车道的发展，其中74％的学生，62％的职员，62％的汽车使用者和82％的公共汽车使用者承认自行车使用量的潜在增加。最后，由于缺乏安全的自行车道仍然是使用两种类型自行车的主要障碍，因此在距学校和工作场所半径12公里的范围内，为骑自行车的人开发和/或改善了舒适安全的基础设施尤其是在主要住宅区和商业区，应优先考虑促进两种类型自行车的使用。
