Understanding Electric Bikes

Before diving into the methods to increase your electric bike's speed, it's essential to understand the basics of how electric bikes work and the speed limitations they come with.

How Electric Bikes Work

Electric bikes, also known as e-bikes, are bicycles equipped with an electric motor that assists with pedaling. The motor is powered by a rechargeable battery, which provides the necessary energy to propel the bike forward. When you pedal, the motor kicks in and amplifies your pedaling effort, offering an extra boost.

Speed Limitations

Electric bikes come with certain speed limitations to ensure rider safety and comply with local regulations. In many countries, including the United States and most European countries, electric bikes are typically limited to a top speed of 20 mph (32 km/h) when using the motor assistance. This limitation ensures that e-bikes are classified as bicycles rather than motor vehicles, allowing them to access bike lanes and paths.

When your eBike exceeds a certain speed, you could be breaking your area’s regulations governing eBikes and potentially be riding your bike illegally. If you choose to modify your eBike and modify the speed limiter, you may need to contact your Department of Motor Vehicles. 

Once your eBike exceeds speeds of twenty-eight miles per hour, it is legally recognized as a moped or motorcycle. In this case, you may need a moped or motorcycle license to legally ride your bike on public property. This means you may also need to register your eBike. 

Factors Affecting Electric Bike Speed

Several factors influence the speed of an electric bike. Understanding these factors can help you identify areas where you can make improvements to enhance your bike's performance.

Motor Power

The power of your electric bike's motor significantly affects its speed. Generally, higher-powered motors provide more torque and propel the bike faster. If you feel your electric bike is sluggish, consider upgrading to a motor with higher wattage or a more efficient design.

Battery Capacity

The capacity and quality of the battery on your electric bike play a crucial role in determining the distance you can travel and the speed you can achieve. Higher-capacity batteries can deliver more power to the motor, allowing for better acceleration and increased speed. If your bike's battery is older or has a lower capacity, upgrading to a higher-capacity battery can positively impact its speed.

Weight and Aerodynamics

The weight of both the rider and the bike itself can affect the speed of an electric bike. Heavier loads require more power to move, potentially limiting the bike's maximum speed. Additionally, optimizing the aerodynamics by minimizing wind resistance can make a noticeable difference in how fast your electric bike can go.

Tips to Make Your Electric Bike Faster

1. Pedal assistance: Many electric bikes come with pedal-assist modes that provide power when you pedal. By putting in more effort while pedaling, you can increase the overall speed of your bike.

2. Decrease resistance: Minimizing resistance can help improve your bike's speed. You can do this by lubricating the chain, ensuring the brakes are not rubbing against the wheel, and making sure the tires are properly inflated.

3. Upgrade the tires: Switching to tires with a lower rolling resistance can enhance your bike's speed. Look for tires designed specifically for electric bikes that prioritize efficiency and reduced resistance.

4. Optimize riding technique: Your riding technique can make a difference in your bike's speed. Try to maintain a consistent cadence (pedaling speed) and shift gears appropriately to find the optimal balance between power and speed.

5. Consider a lightweight frame: If you have the flexibility to change your bike, opting for a lightweight frame can improve your bike's acceleration and overall speed.

6. Ensure proper maintenance: Regularly maintain your electric bike by cleaning it, checking and adjusting the brakes, and keeping the drivetrain in good condition. A well-maintained bike will perform better and may reach higher speeds.

7. Ride with a tailwind: If possible, choose routes that have a tailwind (wind blowing from behind you). A tailwind can provide an additional push, helping you achieve faster speeds.
