Test Power Button: Press the power button on the controller to see if it responds. Sometimes, a simple power cycle can resolve minor issues.

Check Display Panel: If your electric bike is equipped with a display panel, check for any error messages or indicators that may provide insight into the issue. Note any error codes for reference.

Inspect Controller Housing: Carefully examine the controller housing for signs of damage, such as cracks or moisture ingress. If there is damage, call for professional repair services.

Ebike Throttle Does Not Work

The throttle is responsible for direct moving power when you are not pedaling. Here's a detailed guide to troubleshoot and resolve the issue of a malfunctional throttle:

Check Power: Ensure that the battery is adequately charged and securely connected to the throttle system. Without sufficient power, the throttle won't function.

Inspect Wiring: Examine all wiring connections leading to the throttle for any signs of damage, looseness, or corrosion.

Test Throttle Response: Try twisting or pressing the throttle while observing any response from the motor. If there's no reaction, it indicates a potential issue with the throttle mechanism itself, and you might have to replace the throttle altogether.

Ebike Brakes Do Not Work

Ebike brakes are your lifeline, especially in stop-and-go traffic. When they fail, it's crucial to address the issue promptly. Here are the troubleshooting steps:

Assess Brake Engagement: Test both the front and rear brakes to determine if either or both are affected. If one brake works while the other doesn't, it may indicate a specific issue with that brake system.

Check Brake Pads: Inspect the brake pads for wear and tear. Worn brake pads can reduce braking effectiveness and should be replaced if they appear thin or damaged.

Examine Brake Cables: Ensure that the brake cables are intact and properly tensioned. Loose or frayed cables can impede brake function and should be adjusted or replaced as needed.

Verify Brake Lever Operation: Test the brake levers to see if they engage smoothly and return to their original position when released. Sticky or stuck levers may require cleaning or lubrication.

Check Hydraulic Brake Fluid: If your electric bike is equipped with hydraulic brakes, check the brake fluid level and condition. Low fluid levels or contaminated fluid can affect brake performance and should be addressed accordingly.

If all the above steps prove inefficient, consult a qualified electric bike technician for further help. Remember to never hit the road with a pair of faulty brakes.
