As electric scooters become a mainstream choice for urban commuting, users may occasionally encounter malfunctions during daily use. Learning basic troubleshooting not only helps solve problems quickly but also reduces maintenance costs and extends the scooter’s lifespan. This guide covers the most common issues and provides practical solutions.
1. Power and Battery Issues
Common Problems
-
Scooter won’t power on
-
Inaccurate battery level display
-
Significantly reduced range
Troubleshooting Steps
-
Check power switch and wiring – Make sure the switch is functional and all plugs/wires are firmly connected.
-
Test battery voltage – Use a multimeter to confirm the output voltage is within the rated range.
-
Evaluate battery health – If the cycle life has exceeded 800 charges and capacity has dropped sharply, it’s time to replace the battery.
2. Throttle and Controller Problems
Common Problems
-
Throttle not responding or delayed response
-
Unstable acceleration
-
Controller overheating
Troubleshooting Steps
-
Inspect throttle signal wiring – Ensure throttle and controller connections are secure.
-
Check controller compatibility – Some brands (e.g., Yunli controllers) are designed with a universal wiring board for front and rear modules, which makes replacements cheaper and easier.
-
Overheating prevention – Clean dust from heat sinks, and consider upgrading to a higher-capacity controller if overheating persists.
3. Motor Issues
Common Problems
-
Motor won’t spin
-
Abnormal noise or vibration
-
Loss of power
Troubleshooting Steps
-
Check motor wiring – Inspect the three-phase wires and Hall sensor cables for loose or damaged connections.
-
Inspect rotor and bearings – Look for wear, friction, or blockage.
-
Verify motor type – Scooters may use split motors, vacuum split motors, or integrated hub motors. Always replace with the same type for compatibility.
4. Brake System Failures
Common Problems
-
Brakes not working
-
Weak braking force
-
Squeaking or grinding noise
Troubleshooting Steps
-
Hydraulic disc brake check – Inspect for oil leakage, trapped air bubbles, or worn brake pads.
-
Regenerative braking adjustment – Models with Liviae controllers support energy recovery braking, which can be fine-tuned in the app or controller settings.
-
Brake handle and cable inspection – Ensure cables are not broken, stretched, or disconnected.
5. Suspension and Structural Problems
Common Problems
-
Excessive vibration while riding
-
Unstable steering
-
Frame looseness
Troubleshooting Steps
-
Inspect shock absorbers – Check for oil leakage or loss of damping in hydraulic suspensions.
-
Frame and folding mechanism – Tighten all bolts and check whether the folding lock is damaged.
-
Tire selection – Road tires are best for smooth city streets, while off-road tires perform better on rough terrain. The wrong choice can reduce stability and comfort.
Conclusion
Most electric scooter malfunctions are related to the battery, motor, controller, or braking system. By following these troubleshooting steps, riders can quickly locate problems and apply effective solutions. For more complex issues, always consult a professional technician or the manufacturer’s after-sales team to avoid further damage.
A well-maintained scooter not only delivers better performance but also ensures a safer riding experience.
