One of the most frequently asked questions about electric bikes is, "How many CCs does it have?"
This question is appropriate if you are used to riding traditional gasoline-powered motorcycles with engines measured in cubic centimeters (CC).
Electric bicycles don't use horsepower to measure power; instead, they rely on Watts, Volts, and Amp-Hour measurements.
Sound confusing? Have no fear - we will explain everything clearly and concisely.
Why bother asking about horsepower when discussing electric bikes?
Are You Making the Switch From Gas-Powered Bikes to Electric Bikes? If that is your goal, an electric bike could provide something familiar as you compare their differences and similarities.
After all, "CC" has long been seen as the standard indicator of engine power.
With electric bikes, we must think differently.
This guide seeks to demonstrate why carbon credits (CCs) don't apply to electric bikes and how best to intuitively understand electric bike power.
By the end of this guide, you should have all the knowledge needed to understand e-bike specifications and find one suitable for your needs.
What Does "CC" Mean in Vehicles?
Let's start with the basics. "CC" stands for cubic centimeters, and it's a measurement of the engine's size, specifically the volume of the engine's cylinders.
The CC rating of a gasoline engine shows how much air and fuel the engine can take in, mix, and burn to produce power.
Typically, more CCs equates to greater power.
A 1000cc motorcycle typically offers significantly more power and speed than its 250cc counterpart.
But herein lies the difficulty: electric bikes don't contain engines with multiple cylinders.
These motors do not use combustion to power themselves; instead, they use electric motors powered by batteries for propulsion.
"CC" doesn't apply to electric bikes because there are no cylinders to measure.
This is a common misperception and completely understandable if you're familiar with driving gas-powered vehicles for years.
Electric Bikes and Their Power Units
Now that we understand that horsepower units do not apply, you may ask: "So how do we measure the power of an e-bike then?"
Electric bikes are typically measured by Watts (W), Volts (V), and Ampere Hours (Ah).
Here is a breakdown of what these terms entail:
-
Watts (W): Wattage represents the power output of an electric motor; typically, higher wattages indicate greater power and speed.
-
Voltage (V): Voltage is the force exerted on electrical current; higher voltage provides more power for motoring applications.
-
Amp-Hours (Ah): This measure indicates how long a battery can sustain power output.
As opposed to gasoline engines, which rely on increasing CC counts to measure engine power, electric bikes rely on various factors for their performance.
An example is a bike with a 750W motor with more power than a 250W motor.
Comparison may seem unfair, but this is the most accurate way of gauging an electric bike's capabilities.

Converting CC to Electric Bike Units (Watts)
Perhaps you are wondering, "Is there an easy way for me to convert from CCs to Watts so I can compare?".
No direct conversion formula exists as they measure different things—engine capacity (CC) measures engine size, while electrical power (watts) refers to electrical output.
But we can make some rough estimates.
Example: A 50cc gas scooter might produce 2-3 horsepower, roughly equivalent to 1500-2200 watts in an electric motor.
However, remember that these estimates should only be seen as rough estimations.
Electric motors generate power differently than gasoline engines.
Electric bikes typically provide instant torque, making them seem more robust and responsive than a similarly "powered" gas bike.
How to Determine the Power of an Electric Bike
So, if CCs are out of the question, how do you know if an electric bike has enough power for you?
Here’s what to look for:
-
Motor Power (Watts): As mentioned previously, more wattage generally means more power. A 250W motor works excellently for city commuting. At the same time, one with 750W or even 1000W power can better navigate hills and off-road terrains.
-
Voltage (Volts): Increased voltage can improve an electric bike's performance. Common voltage options range from 36V to 48V for standard models, and higher-end ones often offer up to 52V or even more.
-
Torque: While not always listed, torque (measured in Newton-meters) tells you how much "oomph" the motor has when you twist the throttle. More torque means quicker acceleration and better hill-climbing ability.
Consider where and how you plan to ride when selecting an electric bicycle.
A motor with 250W to 500W power will likely suffice for casual city riding.
If your plans involve riding steep hills or off-road terrain, invest in a bike with at least 750W of power output.
Comparing Electric Bikes and Gasoline Motorcycles
A common question regarding electric bikes versus gasoline motorcycles is how they compare against one another.
Understand the variance of performance metrics to be successful in business.
A 1000W electric bike simply cannot match a 600cc motorcycle in terms of top speed or acceleration.
Electric bikes provide other advantages over traditional ones, including instant torque delivery, quiet operation, and reduced maintenance requirements.
An electric bike with a 500W motor may reach 20-28 mph (depending on local laws), while 50cc scooters typically top out between 30-40 mph.
As far as daily commutes in a city go, you might not notice as significant of a difference as expected.
Electric bikes offer additional benefits that motorcycles cannot: bike lanes and trails often do not permit motorcycle use.
Practical Advice for Electric Bike Buyers
Before purchasing an e-bike, assess your riding needs carefully.
Are You Traveling in Flat Cities or Hilly Terrain?
Do you require speed, or is range more important?
Urban commuters usually only require a 250W to 500W motor with a 36V or 48V battery for commuting.
If you require more power, look for models with motors of at least 750W.
Always consult the local regulations regarding e-bike power and speed limitations, as some areas have stringent e-bike rules and speed restrictions.
Conclusion
So, how many electric bikes do electric bikes contain?
The answer is "none."
Electric bikes do not rely on cubic centimeters as an indicator of power; rather, they use watts, volts, and other electrical specifications to measure their capacity.
Understanding these terms might seem complicated initially, but it will help you decide when to select an electric bike that best meets your needs.
FAQs
Do electric bikes have an equivalent CC rating?
No. Since they operate under different principles, there's no direct "CC" equivalent. Watts and volts are commonly measured for electric bikes.
How does electric bike power affect performance?
Higher power (wattage) typically results in better acceleration, top speeds, and hill-climbing ability. However, it also comes with a faster battery drain.
Does a higher wattage always offer advantages?
Not necessarily. While increased wattage could mean more extraordinary power, the range may be reduced significantly if your battery cannot support this additional load.
