If you're thinking about buying an electric bike, you're naturally wondering how much it weighs and if that really matters. The short answer is yes: the weight of an electric bike influences its handling, battery life, and even how comfortable it is to transport or store.
Unlike a conventional bike, an electric bike has a motor, battery, and other components that increase its weight. Depending on your intended use—whether getting around town, going on long rides, or venturing into the mountains—weight can play a key role in your choice.
Average weight of an electric bike
The weight of an electric bike varies depending on the type, materials, and components it uses. It generally ranges between 15 and 30 kilos, while a conventional bike typically weighs between 8 and 15 kilos.
Comparison with conventional bicycles
The weight difference between an electric and a traditional scooter is primarily due to the motor and battery, which can add between 4 and 8 kilos. Although it may seem like a lot, the pedal-assist feature makes this extra weight barely noticeable when riding.
Factors that influence weight
The weight of an electric bike depends on several aspects:
-
The type of bike: city bikes tend to be heavier than road bikes, while mountain bikes require more robustness.
-
The motor: Hub motors tend to be lighter, but central motors offer better performance.
-
The battery: the higher the capacity, the heavier it is. Current lithium batteries have reduced this problem, but it remains a key issue.
-
The frame: Aluminum frames are the most common due to their good balance between weight and strength, while carbon frames reduce weight but make the bike more expensive.
Components that most affect weight
The weight of an electric bike depends on several key factors. Some add more weight than others, and understanding them will help you understand why some bikes are heavier and how to choose the one that best suits you.
Battery: the power source that adds kilos
The battery is one of the components that contributes the most weight. Its weight varies depending on the capacity (measured in Wh) and the type of cells used. Lithium batteries, which are the most common today, have significantly reduced their weight compared to older lead or nickel batteries, but greater autonomy still means more weight.
Engine: location and type make the difference
The motor is another element that most influences the weight of an electric bike. Motors located in the wheel hub are generally lighter, while mid-drive motors, located in the bottom bracket area, are heavier but improve weight distribution and pedaling efficiency.
Frame: aluminum, carbon or steel
The frame material is key to the overall weight. Aluminum is the most common choice because it offers a good balance between lightness and strength. Carbon is lighter, but also more expensive. Steel, although very robust, is the heaviest and is less commonly used in electric bikes.
Wheels and other components
The wheels, tires, and fork also add weight. E-mountain bikes typically have wider, sturdier wheels, which adds weight. Suspension forks, while improving comfort on uneven terrain, also add some extra weight.
How weight influences performance
The weight of an electric bike isn't just a matter of numbers; it directly affects its handling on the road, battery life, and everyday comfort. Depending on your intended use, whether it's lighter or heavier can make a difference.
Battery life and consumption
The heavier an e-bike is, the more effort the motor has to put into moving it, and therefore, the faster the battery drains. If you're looking to travel long distances without worrying about charging, choosing a lighter bike can help you optimize your range.
Maneuverability and comfort
Weight also influences how a bike feels when riding. A lighter bike is easier to handle, especially in tight corners and turns, and is more comfortable climbing curbs or negotiating obstacles. Conversely, a heavier bike can provide greater stability at high speeds, which can be an advantage on certain terrain.
Transport and storage
If you have to carry your bike up stairs, into your car, or on public transport, weight will be a key factor. Folding electric bikes and city bikes are generally lighter for easier handling, while mountain or trekking bikes are heavier because they need to be more durable.
Types of electric bicycles and their approximate weight
The weight of an electric bike varies depending on the type and intended use. Not all bikes weigh the same, as factors such as the motor, battery, and frame material influence the final result. Below is an estimate of the average weight of the main types of electric bikes.
Urban and foldable
Urban electric bikes are designed for comfortable city travel. They typically feature aluminum frames and medium-sized motors. They weigh around 18-25 kilos, depending on the battery and whether they include accessories such as fenders or luggage racks.
Folding electric bikes are more compact and manageable, ideal for those who need to transport them easily. They weigh between 15 and 20 kilos, making them easier to store and transport, although they tend to have less range than other models.
Mountain and gravel
Electric mountain bikes (e-MTBs) are designed for trails and demanding terrain, so they typically feature robust suspension and wider tires, which increases their weight. They can range from 20 to 30 kilos, depending on whether they have dual suspension or front-only suspension.
Gravel e-bikes, designed for dirt roads and long rides, are lighter than mountain bikes. They typically weigh between 16 and 22 kilos, depending on the frame material and battery capacity.
Road and ultralight
Electric road bikes aim to maintain speed while remaining as lightweight as possible. Therefore, they typically feature carbon frames and smaller motors. They weigh between 12 and 18 kilos, making them the lightest on the market.
In the case of ultralight models, designed to maximize aerodynamics and performance, some brands have managed to manufacture electric bikes under 12 kilos, although these are usually high-end models with high prices.
Tips for choosing the best option according to weight
The weight of an electric bike is a key factor when choosing the right model, but not the only one. While a lighter bike may seem better, in some cases a little more weight means greater stability or range. Here are some tips to help you find the perfect balance for your needs.
Think about what you are going to use it for
Not all electric bikes are designed for the same purpose. If you need a bike for getting around town, a lighter folding or city bike will make commuting and transport easier. If you're looking to travel long distances or hike mountain trails, you might want a more robust model, even if it weighs more, to ensure better range and stability.
Find the balance between weight and autonomy
A larger battery will allow you to travel more miles, but it will also add weight to the bike. If you don't need great range, opting for a smaller battery will help you reduce weight without sacrificing efficiency.
Choose the frame material well
The frame material makes a big difference in weight. Aluminum is the most balanced option because it's both light and strong. Carbon is even lighter, but more expensive. Steel, although very durable, is the heaviest and least recommended if you're looking for agility.
Consider how you will transport and store it.
If you have to carry your bike up stairs, load it into the car, or store it in a small space, the lighter the bike, the better. In these cases, opting for lighter or foldable models will make it much easier to handle on a daily basis.
