Physical activity (PA) is highly recommended in the management of most chronic diseases. For these patients, the smart electric bicycle can be effective to improve adherence to this behavior. The E-bike used in this study (called VELIS) has an innovative onboard technology that allows for subject monitoring and the engine power is designed to adapt to the user's abilities. A prerequisite for the use of the VELIS with patients is to initially carry out a pilot study on healthy subjects. The objective was to evaluate the impact of the customizable settings on physiological parameters and to ensure this prototype's efficiency and safety of use. Twelve healthy participants with various profiles (physical condition, used to cycling or not) were included. They have completed four times a 14 km itinerary with various settings of the VELIS. We recorded GPS data, heart rate and perceived exertion. Based on exercise intensity, we confirm that riding an E-bike should be considered as a physical activity. Safety of the participants is ensured by the engine brake. Recordings show that it took between 1 and 3 min for the novice to become familiar with the VELIS and to get optimal assistance. The main finding of this pilot study confirms that VELIS is an easy to use and secure tool to make PA approachable, whatever the level of training in healthy subjects.

在大多数慢性疾病的治疗中，强烈建议进行体育锻炼（PA）。对于这些患者，智能电动自行车可以有效地改善对此行为的依从性。这项研究中使用的电动自行车（称为VELIS）具有一项创新的车载技术，可以对对象进行监控，并且发动机功率旨在适应用户的能力。对患者使用VELIS的前提条件是首先对健康受试者进行一项初步研究。目的是评估可定制设置对生理参数的影响，并确保该原型的使用效率和安全性。包括十二名健康参与者，他们具有各种特征（身体状况，是否习惯骑自行车）。他们使用VELIS的各种设置完成了14公里行程的四次。我们记录了GPS数据，心率和感知的运动量。根据运动强度，我们确认骑电动自行车应被视为一项体育活动。发动机制动器确保了参与者的安全。记录显示，新手需要1到3分钟才能熟悉VELIS并获得最佳帮助。这项初步研究的主要结果证实，无论健康受试者的培训水平如何，VELIS都是一种易于使用且安全的工具，可以使PA变得容易接近。记录显示，新手需要1到3分钟才能熟悉VELIS并获得最佳帮助。这项初步研究的主要结果证实，无论健康受试者的培训水平如何，VELIS都是一种易于使用且安全的工具，可以使PA变得容易接近。记录显示，新手需要1到3分钟才能熟悉VELIS并获得最佳帮助。这项初步研究的主要结果证实，无论健康受试者的培训水平如何，VELIS都是一种易于使用且安全的工具，可以使PA变得容易接近。
