How to add electric motor to bike?

Adding an electric motor to a bike can be done with a conversion kit. These kits typically include a motor, battery, and controller that can be attached to the bike's frame or rear wheel. It's important to choose a kit that matches your bike's size and style, as well as your desired level of motor power and range. Some kits provide pedal-assist support, while others are throttle-based. Installation can be done yourself with some technical knowledge and the right tools, or you can hire a professional to do it for you. Always follow the instructions carefully and test the system thoroughly before use.
