Detailed Analysis of Two Types of Power Issues in Electric Bikes
Electric bikes typically experience two kinds of power issues:
- Complete Power Loss: The bike cannot start or loses power entirely.
- Intermittent Power Loss: Power cuts off suddenly during a ride but then resumes.
These issues are usually caused by two major factors: hardware problems and improper use. Below is a detailed breakdown of potential causes and their symptoms.
Hardware Issues
Battery Issues
-
Battery Aging:
-
Symptoms:

- Solution: Replace the battery to ensure stable power output.
-
Symptoms:
-
Loose or Dirty Contacts:
-
Symptoms:
- Power cuts off intermittently during startup or riding.
- Dashboard display flickers; removing and reinserting the battery temporarily resolves the issue.
- Solution: Clean the contacts and adjust the battery slot for a proper fit.
-
Symptoms:
-
Over-Discharge:
-
Symptoms:

- Use the official app or tools to install updates as instructed.
- If the problem persists, contact after-sales support for further diagnosis.
Improper Use
Overloading During Riding-
Symptoms:
-
When the load exceeds the designed carrying capacity of the electric bike (e.g., carrying excessive cargo or passengers), the motor becomes overburdened, leading to intermittent power cuts or significantly reduced power output.
-
-
Solutions:
-
Check the bike's user manual to ensure the load is within the design limits.
-
Avoid prolonged riding under heavy load, especially on inclines or complex terrain. For riders of an off-road e-bike, this ensures optimal performance during demanding adventures.
-
Environmental Factors
-
Symptoms:
-
In high-temperature environments, the battery may overheat, triggering a protection mechanism that causes power loss.
-
In extremely low temperatures, the battery may output insufficient current, leading to reduced power or even power cuts.
-
In wet or rainy conditions, water may enter the wiring, causing a short circuit, often accompanied by a "buzzing" sound when power cuts occur.
-
-
Solutions:
-
Use the electric bike in moderate temperatures and avoid exposing it to extreme heat or cold.
-
After riding in the rain, clean and dry cable connectors promptly, ensuring the bike is completely dry.
-
Throttle Operation Issues
-
Symptoms:
-
A stuck throttle can cause uneven power output, resulting in sudden acceleration or power cuts.
-
Excessive throttle use may interrupt power supply, requiring throttle adjustment to restore normal operation.
-
-
Solutions:
-
Regularly check throttle sensitivity and rebound to prevent wear or sticking.
-
Operate the throttle smoothly during rides and avoid abrupt or extreme adjustments.
-
Over-Discharging
-
Symptoms:
- After prolonged riding without timely charging, the battery may completely drain, triggering the battery's low-voltage protection, rendering the bike unable to start.
-
Solutions:
- Develop a habit of charging the battery promptly and avoid fully depleting the charge before recharging.
- Monitor battery level indicators during use and stop riding to recharge when the battery is low.

Electric Bike Power Loss Solutions: From Prevention to Response
Power loss in electric bikes is a common issue, but it can be effectively avoided with proper preventive measures and correct responses. Here are some key tips to ensure smooth and safe rides:
How to Avoid Power Loss Issues
Regular Inspections
-
Battery Connections:
- Ensure that the battery’s contact points with the slot are clean and secure to prevent poor connections caused by looseness or debris.
- Use a dry cloth to clean the contact points and check that the slot is free from obstructions.
- Regularly inspect the battery latch for any looseness.
-
Cables and Wiring:
- Regularly inspect the wiring connections, especially at the joints, for signs of looseness, aging, or damage.
- Check for worn or damaged cables and reconnect loose joints. Use waterproof tape to reinforce damaged areas.
Timely Maintenance
-
Battery Maintenance:
- Periodically check the battery’s health, including its capacity and output voltage, to prevent complete power loss caused by aging or over-discharge.
- Perform a full charge and discharge cycle once a month, and use professional equipment to test battery capacity and voltage. Replace the battery if anomalies are detected.
-
Controller and Motor:
- Inspect the controller and motor’s cooling performance and promptly remove dust and debris to ensure proper heat dissipation.
- Clean dust from cooling vents and ensure smooth heat dissipation. Check for unusual noises or stuttering after extended use.
Usage Precautions
- Avoid prolonged high-load riding, such as frequent hill climbing or carrying heavy loads, to reduce excessive strain on the motor and battery.including folding e-bikes, which are designed for compact convenience but still benefit from reasonable usage practices.
- Load reasonably, staying within the bike’s weight capacity.
- Pay attention to riding environments, avoiding extended exposure to extreme heat, cold, or humidity.
- Avoid riding for long periods in extreme weather conditions to protect the battery and motor from damage.
Software Updates
- Regularly check for available updates for the system or controller software. Updating can optimize compatibility, resolve potential issues, and improve the stability of your electric bike.
How to Quickly Restore Power When an Electric Bike Cuts Out
Quick Recovery Measures for Complete Power Loss
Check Battery Connection
Ensure the battery is securely connected to the slot. Loose or poor contact is a common cause of power loss. Remove and reinsert the battery, making sure it’s properly connected.
Check Battery Level
Verify that the battery is fully charged. If the battery is low or completely drained, use the appropriate charger to recharge it and avoid power loss caused by low voltage protection.
Restart the Electric System
Press and hold or toggle the bike’s power button to restart the system. This may resolve temporary system glitches or controller issues.
Inspect the Fuse
Check whether the bike’s fuse is blown. If the fuse is damaged, replace it with one of the correct specifications.
Contact After-Sales Support
If the above methods do not work, the issue may lie within the controller or internal battery components. In this case, stop using the bike and contact Fiido’s professional after-sales team at support@fiido.com for diagnosis.
Quick Recovery Measures for Intermittent Power Loss
Check for Loose Connections: Focus on the connectors for the battery, controller, and motor. Re-secure any loose connections.
Cool Down the Motor or Controller: If the motor or controller is overheating, stop riding and wait for it to cool down (usually 5-10 minutes). Avoid prolonged high-load riding to prevent overheating.
Inspect Sensors and Controller: Adjust the sensors and wiring on the bike to ensure they have not shifted or loosened due to vibration. If the issue persists, contact a professional for detailed inspection.
Update System Software: Check for the latest firmware or software updates. Updating the software may resolve compatibility issues between the controller and sensors.
