Several factors can affect the performance of hub motors, including the type and quality of the motor, the size and type of the wheel, the type and condition of the bearings, and the operating environment (e.g., temperature, humidity, vibration, etc.).
To choose a battery for a hub motor, consider the voltage, capacity, and chemistry compatibility, ensuring it can provide enough capacity for the desired range and meets the application's needs, such as high performance or cost-effectiveness.
Ensure that your battery is fully charged before using your ebike so that it will not die completely while you are riding! Geared hub motors are the most common type of motor for electric bikes. Typically, they have a lifespan of about 500 hours, although this does depend on what kind you get and how often you use it.
