Why Can’t the Maximum Speed of Electric Scooter be Reached?

Electric scooters have become a new favorite for urban travel in recent years. しかし, many users have found that their electric scooters cannot reach the advertised maximum speed during use. Why? Let’s explore the reasons why electric scooters cannot reach the maximum speed.

Factors affecting the speed of electric scooters

The speed of an electric scooter depends on several factors, including the motor power of the electric scooter, バッテリー容量, rider weight, terrain, tires and tire pressure, 等. The driving speed mainly depends on the output power of the motor. The higher the motor power, the faster the speed. On flat roads without too many vehicles, you can choose a higher-powered electric scooter to increase the speed. しかし, the motor output power is not the only factor that affects the speed. Road conditions are also very important. 例えば, uneven roads or a large number of pedestrians will affect the speed. For your safety, a speed of around 20km/h may be a suitable choice.

Factors
Overview
Analysis
Motor power
The higher the power, the greater the acceleration and the faster the speed
Determine the top speed of the scooter
Controller
Sine wave and square wave controllers are two different speed adjustment methods for electric scooters
Sine wave controllers provide smoother and more stable acceleration and deceleration processes, making riding more comfortable, while square wave controllers may cause the speed changes to be less smooth and may cause instability.
Battery capacity
The battery is the power that drives the motor, which indirectly affects how long the scooter can maintain its speed.
A larger battery capacity will be able to maintain the speed for longer.
Rider weight
When the rider is heavier, the total load the scooter needs to carry increases.
Carrying a heavier rider requires more motor power to accelerate the scooter and will also affect the scooter’s top speed.
Terrain type
Riding up hills or over rough terrain can also slow down the scooter
Uphill and downhill slopes, gravel or unpaved roads will slow the scooter; the presence of obstacles (such as speed bumps, potholes or sharp turns) may require slowing down the speed.
Tire type and pressure
Wider tires and lower tire pressure will generally make the scooter go slower.
A tire with good grip can maintain higher speeds more efficiently. Conversely, a tire with poor grip or worn tread may limit speed.

The reason why the electric scooter does not reach full speed

Reasons
Malfunction
Cause Analysis
Solutions
Battery
Low battery
When the battery is depleted, your e-scooter may not have enough power to reach full speed.
You need to understand how to charge your electric scooter battery regularly to ensure optimal performance.
Battery or charger failure
If the battery or charger fails, the scooter motor will not receive enough power, resulting in slower acceleration and reduced overall speed.
Take it to a certified technician for a complete inspection, repair, or replacement.
モーター
When the motor becomes too hot, it may enter protection mode
When a motor gets too hot, it may go into protection mode and its speed is limited to prevent damage.
If you find your electric scooter is overheating, stop riding for a while.
Physical damage or internal failure inside the motor
A damaged motor may not produce enough power, making it difficult for the scooter to reach higher speeds.
Take it to a certified technician for a complete inspection, repair, or replacement.
Tire
Insufficient inflation
Lower tire pressure also reduces the efficiency of the scooter because the motor has to work harder to turn the tire.
初め, you need to confirm the desired air pressure. Then, you can use an air pump and the appropriate nozzle to inflate the tire. Insert the nozzle into the tire valve and use the air pump to inject air into the tire until the desired air pressure is reached. ついに, make sure the nozzle and valve are securely connected and check that the tire is fully inflated.
Tire tread wear
Tires with poor grip or worn tread may result in reduced traction, especially on slippery surfaces, which can limit the speed of the scooter.
You may want to consider replacing your tires with new ones to ensure safety and performance. If you are not sure how to replace tires, it is best to ask a professional to help you do it.
Controller
Faulty or damaged controller, loose or broken wires
Wear and tear caused by long-term use or external impact
Please contact after-sales for professional repair or replacement of the controller. Make sure all wires in the controller are properly connected and insulated.
モード
Lower speed mode
In low-speed mode, the power output of the motor will be limited to a lower level, which will limit the speed, climbing ability and acceleration performance.
Check the scooter’s mode settings to make sure it is not inadvertently in low-speed mode. Consult your owner’s manual for the different mode options and their corresponding speeds. If you are unable to identify or resolve the speed issue, consider taking your scooter to a certified technician for a full inspection and repair.

How to identify and resolve specific issues that may be slowing down your e-scooter

Analysis
Specific measures
Battery check
Make sure the battery is fully charged.
Test the functionality of the battery charger and ensure that it charges the battery correctly.
Motor check
Check if the motor makes unusual noises or generates excessive heat during operation.
Overheating will reduce speed, if the motor is damaged or malfunctioning, repair or replace it.
Tire check
Check tire pressure by using a pressure gauge
Maintain recommended pressure levels. Check tire tread for wear and replace worn tires
Controller check
Make sure all wires inside the controller are properly connected and insulated.
Check for any obvious damage or loose connections, any exposed or frayed wires.
Mode setting verification
Select the appropriate mode based on your desired speed and terrain conditions.
Make sure it is not accidentally left in low speed mode.

How to optimize the speed of electric scooters (removing the speed limiter)

Specific method
手術
Risks
Remove the speed limit wire
One method some riders have tried is to tinker with a specific wire to increase the scooter’s speed. By disconnecting this wire, it is possible to cause the speed limiter to detect that the scooter is moving slower than it actually is, effectively bypassing the speed limiter.
This method has many risks. Not only interfere with the speed limiter, but also may disrupt other electronic functions of the e-scooter.
Switch to “Sport Mode
When operating a scooter, you must be aware of the various features and options. One of these options is the “Sport Modeoffered on some scooter models. This feature allows you to modify the performance of the scooter, increasing its maximum speed and potentially enhancing your riding experience.
It is best to use caution when using this mode as it also increases the risk of an accident or other unforeseen events. To ensure safety while riding, please familiarize yourself with the limitations of the “Sport Modeoption and take appropriate precautions to avoid any potential hazards.
Replace electrical components
Replacement of certain components, such as controllers or motors. しかし, this type of work requires a high degree of electrical handling skills.
If you are not familiar with these electronics and wiring, it is best to leave it to the professionals. Attempting to repair components yourself may void your warranty benefits.

Some brands of electric scooters can unlock the maximum speed limit by entering the engineering mode setting.

結論

It is recommended that riders do not ride electric scooters at excessive speeds. Excessive speeds increase the risk of traffic accidents because riders may not be able to avoid obstacles or other vehicles in time. 加えて, riding at high speeds also increases the likelihood of falling, especially when the road surface is uneven or slippery. To ensure safety, riders should wear protective gear, maintain an appropriate speed, obey traffic rules, avoid speeding on the sidewalk, always pay attention to the surrounding environment, and be ready to brake or evade at any time. Remember, safety is most important, and riding slowly and enjoy the fun of electric scooters.
