Scope

Main Technical Content: (1) Functional Requirements The difference between functional requirements and performance requirements lies in the following: - **Functional Requirements**: They describe what the product can do for users, focusing on the "what the product can achieve." - **Performance Requirements**: They serve as indicators for evaluating the product’s quality, measuring how well the product performs. Therefore, the "what the product can achieve" can be used to distinguish smart power cycling trainers from non-smart ones. This standard defines the distinction based on the functional capabilities of the trainer, with specific mandatory and optional requirements for smart power cycling trainers in terms of operating modes, output data types, and protocol support. Among the three operating modes—resistance level mode, slope simulation mode, and target power mode—resistance level mode is the most critical for cyclists when choosing a smart trainer. Power, torque, speed, and cadence are the four key data types. Power is the most important data for users. Traditional cycling trainers typically provide fixed resistance modes by controlling resistance, but they cannot output power data, which requires external power meters. Therefore, providing power data is a fundamental requirement for smart power cycling trainers. Whether the trainer supports protocols is a simple way to distinguish between smart and non-smart trainers in the industry. Supporting protocols is widely considered a prerequisite for smart trainers. (2) Power Accuracy Power is a critical data point for cyclists during training. High power accuracy plays a crucial role in meeting training goals. Considering that cycling trainers cater to a broad user base—from casual enthusiasts to professional athletes—we set different accuracy requirements to balance user needs and product cost-effectiveness. The upper limit of the accuracy rating should not exceed 10% error, as even for casua
