What Makes an Electric Scooter Go Slower?

Electric scooters are becoming increasingly popular for their convenience and eco-friendliness. If you own one that can reach speeds of 20mph electric scooter, you know the joy of zipping around town quickly and efficiently. However, there might be times when your scooter isn’t performing as well as you’d like. Understanding what makes an electric scooter go slower can help you troubleshoot and maintain optimal performance.

Battery Health and Charge Levels

One of the most common reasons your electric scooter might be going slower is related to its battery. The battery is the powerhouse of your scooter, and its health and charge levels significantly affect the electric scooter speed.

Low Battery Charge

When the battery charge is low, the scooter’s performance can drop. Many scooters have built-in systems that limit speed to conserve battery life. Make sure to keep your battery well-charged to maintain top speeds.

Battery Degradation

Over time, batteries lose their ability to hold a full charge. If your scooter’s battery is old or worn out, it might not provide the power needed for peak performance. Consider replacing the battery if you notice a significant drop in speed.

Tire Condition and Pressure

Tires play a crucial role in the performance of your electric scooter. Both the condition and pressure of the tires can impact your scooter’s speed.

Underinflated Tires

If your tires are underinflated, they create more friction with the ground, which can slow down your scooter. Check your tire pressure regularly and keep them inflated to the recommended levels.

Worn-Out Tires

Worn-out tires can also affect speed. If the tread is worn down, the scooter might not grip the road as effectively, leading to slower speeds. Replace tires that show signs of significant wear and tear.

Weight Load

The weight load on your scooter can affect how fast it can go. Electric scooters have a maximum weight capacity, and exceeding this limit can reduce speed.

Carrying Extra Weight

If you’re carrying heavy bags or if the combined weight of you and your cargo exceeds the scooter’s capacity, you’ll likely notice a decrease in speed. Try to stay within the recommended weight limits for optimal performance.

Terrain and Riding Conditions

The type of terrain you ride on can have a significant impact on your scooter’s speed.

Uphill Rides

Riding uphill requires more power from your scooter. Even with a fully charged battery, you might notice a slower speed when climbing hills.

Rough or Uneven Surfaces

Rough or uneven surfaces create more resistance, which can slow down your scooter. Smooth, flat surfaces are ideal for maintaining top speeds.

Mechanical Issues

Mechanical issues can also be a factor in reduced scooter speed. Regular maintenance can help prevent these problems.

Motor Problems

If the motor isn’t functioning properly, it won’t provide the necessary power. Listen for unusual noises or vibrations, which can indicate motor issues. Regularly inspect and service the motor to ensure it’s in good working condition.

Brake Drag

Sometimes, the brakes might drag slightly even when not engaged, creating friction that slows the scooter down. Check the brake system and adjust if necessary to prevent drag.

Software and Settings

Modern electric scooters often come with software that can impact performance.

Speed Limit Settings

Many scooters have adjustable speed settings. Ensure that your scooter isn’t set to a lower speed limit. Check the user manual to adjust these settings appropriately.

Firmware Updates

Firmware updates can improve the performance of your scooter. Ensure that your scooter’s firmware is up-to-date to benefit from the latest improvements and fixes.


Understanding what makes an electric scooter go slower can help you keep your ride smooth and fast. Regular maintenance, proper tire care, battery management, and adhering to weight limits can all contribute to maintaining optimal speed. If you encounter persistent issues, consulting with a professional or referring to your scooter’s user manual can provide additional guidance. Keep your scooter in top shape to enjoy those swift 20mph rides around town!
