The decline in bicycle usage as a form of transport can be attributed to inadequate infrastructure and safety concerns. Regarding the former, as cities grow and become more densely populated, there is often a lack of adequate infrastructure to support safe and convenient cycling. Narrow roads, limited bike lanes, and inadequate cycling facilities can deter people from using bicycles as a mode of transport, especially in areas with heavy traffic or poor road conditions. Concerning the other reason, certain perceived risks associated with cycling, including accidents, collisions with motor vehicles, and theft of bicycles, can deter people from using this mode of transport, especially in busy urban areas with high levels of traffic congestion. This is the case of Vietnam where cyclists often voice their concerns with potential collisions with motorcycles when navigating busy roads, which has undermined confidence in cycling as a viable mode of transport.
