Choosing the right KT controller depends on your ebike's motor wattage and battery voltage.

• Check your motor's power rating (e.g., 250W, 750W, 1000W) and match it with a compatible controller.
• Verify your battery voltage (usually 36V, 48V, or 52V) to ensure the controller supports it.
• Consider the connector type (waterproof or SM plug) for easy installation.
• If you plan to use a display, make sure the controller supports KT LCD or LED displays.

Review your ebike specs and look for controllers that fit those requirements for smooth performance.

KT controllers can often be used when upgrading your ebike motor, as long as the new motor's wattage and voltage match the controller's specifications.

• Check compatibility between the controller and the upgraded motor.
• Ensure the connectors (PAS, throttle, display) are suitable for your setup.
• Upgrading may require additional wiring or adjustments, so review the installation instructions carefully.

It's a good idea to consult your motor's documentation or reach out to the manufacturer for guidance before making changes.

Sine wave controllers provide smoother and quieter motor operation, which can enhance your riding experience.

• They help reduce noise and vibration, making the ride more comfortable.
• Square wave controllers are generally simpler and may be more affordable, but can produce more noise and less efficient power delivery.

Choosing between the two depends on your priorities for comfort, efficiency, and budget. Always check your motor's compatibility before selecting a controller type.

Installing a KT controller typically involves connecting the controller to your motor, battery, and display.

1. Turn off and disconnect the battery before starting.
2. Match each connector (motor, PAS, throttle, display) to its corresponding port on the controller.
3. Secure the controller in a dry, protected spot on your bike frame.
4. Reconnect the battery and test the system.

Refer to the included instructions for specific wiring diagrams and safety tips. If you're unsure, consider seeking help from a bike technician.

Many KT controllers feature waterproof plugs and casings, which can help protect them during wet conditions.

• Look for controllers labeled as waterproof or with sealed connectors.
• Even with waterproof features, it's best to avoid prolonged exposure to heavy rain and ensure the controller is mounted away from direct water spray.
• Regularly check for any signs of moisture or corrosion to maintain performance.

Proper installation and care can help your controller last longer, even when riding in damp weather.
