Compatibility and suitability
Firstly, consider the type of bicycle you have and its features. Mountain bikes, for example, have a strong frame and suspension, making them well-suited to handle the added weight and power of e-bike components. Hybrid or commuter bikes offer a comfortable geometry and a stable platform for conversion. Additionally, consider the wheel's diameter, width, and axle standard, as well as the type of brakes your bicycle has. Disc brakes, for instance, offer superior stopping power, which is crucial for the increased speeds that e-bikes can achieve.
Secondly, choose the right conversion kit for your bicycle. Conversion kits are available in different types, such as those with the motor located at the wheel's hub or crank-driven systems. For wheel-hub motors, ensure compatibility by matching the wheel diameter and axle standard, as well as considering the type of brakes. Crank-driven systems typically require an alloy frame and a bottom bracket width between 68 and 73mm, which is standard for most road and mountain bikes.
Thirdly, consider the condition and componentry of your bicycle. The addition of an electric motor will increase torque, so ensure that your drivetrain is in good condition to avoid poor performance or damage to the chain. Assess whether your brakes are adequate for the added power and speed of an e-bike. Upgrading to a more robust disc brake system may be necessary for safety reasons.
Finally, consider the space available on your bicycle frame for mounting the motor and battery. Look for existing mounting points, typically within the main triangle, to position the battery. Ensure there is sufficient space around the wheel hub or bottom bracket for proper installation of the motor. Additionally, match the battery and motor voltage to avoid compatibility issues.

Installation process
The process of converting a bicycle to an electric bike involves adding an electric motor, a battery pack, a controller, and several other components to the bike. It is important to have a solid understanding of the fundamentals of electric bicycle conversion before beginning the process.
Firstly, assess your bicycle's suitability. Ensure your bike has a sturdy frame and enough space for the motor and battery. It is also crucial to verify that your bike is compatible with your chosen conversion kit, considering factors such as wheel size and brakes.
Once you have chosen the right conversion kit for your bike, it's time to start the installation process. The first step is to remove some existing parts from your bicycle. This may include detaching the pedals, chain, wheels, and potentially the brakes, depending on the specific conversion kit you are using. Carefully disassemble these components and keep track of the hardware for later reassembly.
The next step is to install the motor. The installation process will depend on the type of motor you have chosen. If you have selected a hub motor, typically the easiest type to fit, you will replace your front or rear wheel with the motor wheel provided in the conversion kit. If you have chosen a mid-drive motor, which achieves higher performance by spinning the front chainring directly, you will need to perform more disassembly. This often involves removing the bottom bracket and cranks to install the motor in their place.
After installing the motor, you will need to attach the cadence sensor, which detects when you are pedalling and need assistance. Then, attach the battery and the LCD display, which allows you to monitor your battery level. Ensure that the battery voltage and output match the motor, and verify that your charger is compatible to prevent safety hazards.
Finally, connect all the components, carefully following the directions provided by the manufacturer. Pay close attention to the routing of the wires and ensure that all connections are secure. Once the wiring is complete, perform a comprehensive system test to ensure that all components are functioning as expected.
