General Motors Canada (or GM) has recognized that the significance of e-bike use as an integral part of the urban mobility of the future can no longer be ignored. To promote mass adoption of the integration of e-bikes with cars, GM has identified that issues of comfort, riding stability, handling, wind loads, drag, safety, power output, efficiency, etc. under different climatic conditions need to be addressed. This project intends to address the above issues in order to promote the integration of e-bikes with cars. The objective of the proposed project is therefore to develop full scale climatic wind tunnel test techniques to investigate the effects of cross-wind loads on cyclists and the human power output under different climatic conditions. Additionally, the ride stability and comfort of cyclists under different cross-wind and climatic conditions will be examined. To achieve this objective, the applicant plans to conduct the studies in the full scale climatic wind tunnel at the University of Ontario Institute of Technology, which is well suited for these types of studies. The project will first integrate a high precision bicycle ergometer and bicycle computers as well as pressure and flow sensors including flow angle probes. The system will be calibrated and tested to ensure that it is accurate and reliable for the studies. It will also be used to measure a rider's power output, heart rate and cadence as well as simulate different road elevations. Furthermore, pressure, and flow sensors including flow angle probes will be used to accurately measure pressure, flow velocities and directions; which can be used to estimate wind loads on cyclists. The insight from the proposed project will help to improve and optimize the design of e-bikes and the comfort of cyclists. It will also promote the integration of e-bikes with cars and its mass adoption for the urban mobility of the future. This can in turn reduce traffic pollution with a positive impact on the health, environmental and economic conditions of Canadians. The collaboration between scientists/engineers from industry and academia will provide an additional opportunity to train students with the essential skills needed by Canadian industries.

加拿大通用汽车（或通用汽车）已经认识到，电子自行车用作未来城市流动性不可或缺的一部分的重要性不再被忽略。为了促进大量采用电子自行车与汽车的集成，通用汽车已经确定，在不同的气候条件下，需要解决舒适，骑行稳定，操纵，防风，安全性，功率，功率，效率等的问题。该项目旨在解决上述问题，以促进电子自行车与汽车的整合。因此，拟议项目的目的是开发全尺度气候风洞测试技术，以研究在不同气候条件下跨风负载对骑自行车者和人类力量输出的影响。此外，将检查在不同的交叉和气候条件下骑自行车者的骑行稳定性和舒适性。到 实现这一目标，申请人计划在安大略大学理工大学的全尺度气候风洞中进行研究，该研究非常适合这类研究。该项目将首先集成高精度的自行车测量计和自行车计算机，以及包括流动角探针（包括流动角探针）的压力和流动传感器。该系统将进行校准和测试，以确保其准确且可靠。它也将用于测量骑手的功率输出，心率和节奏，并模拟不同的道路高程。此外，压力和流动传感器（包括流动角探针）将用于准确测量压力，流速和方向。可用于估计骑自行车的人的风载。拟议项目的见解将有助于改善和优化电子自行车的设计和骑自行车的人的舒适性。它还将促进电子自行车与汽车的整合及其对城市的大量采用 未来的流动性。反过来，这可以减少交通污染，并对加拿大人的健康，环境和经济状况产生积极影响。来自行业和学术界的科学家/工程师之间的合作将为培训加拿大行业所需的基本技能的学生提供额外的机会。
