Understanding the factors that affect the ebike weight

E-bikes are becoming increasingly popular as a means of transport, especially in urban areas. Compared to conventional bikes, electric assisted bikes have more components and therefore weigh more. This article further discusses the factors that determine the weight of an e-bike.

How much does an ebike weigh?
The weight of an e-bike is a factor that many consumers often consider when making a purchase. Typically, a conventional bike weighs 15kg, while an e-bike weighs 20-30kg or more. This depends on the type of ebike and you can see the average weight of different types of e-bikes here.

Factors affecting the weight of an e-bike

Frame material
Various e-bike handlebars are available in different frame materials. These include aluminium, carbon fibre, titanium and steel frames. Aluminium and carbon fibre frames are usually lighter than steel frames. Aluminium is a popular choice for e-bike frames because it is lightweight, strong and durable. It is also relatively cheap, making it a budget-friendly option. As a result, most modern manufacturers, such as HOTEBIKE, use aluminium frames in their production. Carbon fibre frame types are also light, but more expensive than aluminium. Nonetheless, it provides a smoother ride and optimal performance, making it a popular choice for high-end e-bikes.

If you want the cheapest frame material, consider steel. However, it is usually heavier than aluminium or carbon fibre. Titanium is also a strong, lightweight and corrosion-resistant material commonly used for high-end e-bike frames. The main setback is the high price. Therefore, manufacturers ensure that they do not use expensive materials for production and do not compromise on operational costs. Also, some manufacturers use wood to produce e-bike frames. Although it gives a unique and natural look, it is heavier and less durable than other products.

Pedal assist or throttle function
E-bikes or three wheel ebike can be equipped with either pedal assist or a throttle. Pedal-assist systems require the rider to step on the pedals to activate the motor and tend to be lighter than throttle-based systems, which can be activated without stepping on the pedals.

E-bikes with throttles allow the rider to control the power provided by the motor by twisting the throttle handle on the handlebars. On the other hand, pedal-assisted e-bikes power the pedals only when the rider presses the pedals. The energy provided by the electric motor is proportional to the rider’s pedal effort, so the harder the rider pedals, the more power is provided. This means that a throttle-controlled e-bike may be easier for riders who are unable or unwilling to pedal. Pedal-assisted e-bikes can provide a more natural and efficient riding experience for riders who are able and willing to pedal.

Battery Type
The type of battery used in an e-bike can also affect its weight. Typically, the two common types of batteries are lithium-ion and lead-acid. Also, lithium-ion batteries are usually lighter than lead-acid batteries. This significantly affects the overall weight of the e-bike. They also have a higher energy density, which means they can store more energy in less space than lead-acid batteries. This means that a lithium-ion battery of a given size will typically have a longer range than a lead-acid battery of the same size.

E-bike batteries using the lithium-ion type also have a longer lifespan than lead-acid batteries. However, specific user maintenance procedures can also affect the durability or life of an e-bike battery. Since lithium-ion charges faster than lead-acid batteries, it is less prone to electrical damage. More importantly, you should know the charging time of your e-bike battery, which is usually stated in the user manual or guide.

The only disadvantage of lithium-ion batteries is their high cost. It is usually more expensive than lead-acid batteries due to the improved technology used in production. Nevertheless, it offers greater weight, flexibility and durability advantages.

Motor type
Another factor that may affect the size of an e-bike is the motor type. The two main motor types are hub motors and mid-drive motors, with the main difference being their location in the e-bike. Mid-drive motors are located in the middle of the bike, usually near the pedals. They are attached to the bike’s chain, which allows them to use the bike’s gears to amplify their power. This makes mid-drive motors great for climbing hills and tackling challenging terrain. However, they can be more expensive and require more maintenance.

Hub motors are located in the hub of a bicycle wheel (usually the rear wheel). They are simpler, easier to maintain and often cheaper than mid-drive motors. However, they do not provide the same level of performance as mid-drive motors because they do not have access to the gears of the bike.

In terms of weight, mid-drives are heavier than hub motors. As a result, modern manufacturers have turned to hub motor types and improved their attributes for more efficient use; in this way, hub motors can operate effectively as medical drive motors and are considered perfect for the average or typical commuter.

Added Accessories
The number and type of accessories added to an e-bike can affect its weight. These include racks, lights, baskets, wings, and more. The weight of these accessories can range from a few ounces to a few pounds, depending on the specific item. For example, the weight of a basket or rack can vary from a few ounces to a few pounds, depending on the size and material. At the same time, these accessories are essential in an electric bike because some of them have protective features. For example, wings protect the rider from mud and water, while lights improve visibility and safety. You can still opt for lightweight versions of these accessories that will perform at their best.

Wheel size
The wheel is an integral part of an e-bike. It helps to increase the speed of the e-bike in motion. Generally, larger wheels may be slightly heavier than smaller ones due to their size, but the weight difference is usually not significant. On the other hand, the material of the wheel can have a more substantial impact on the weight of an e-bike. For example, aluminium or carbon fibre wheels may be lighter than steel wheels.

Lightweight or heavy duty e-bike?
You must answer this question by considering how you will use your e-bike. If you need to take your e-bike to the office or to a flat without a lift, a lightweight or foldable e-bike is usually recommended.

If you need to ride your e-bike for long distances, weight is less important than range and speed. Therefore, buying a long range e-bike should be your first choice.

Therefore, if you are very concerned about the weight of an e-bike, the above factors can serve as your buying reference. But most importantly, follow your needs. Either way, an e-bike is a tool that can add power to your ride for a simple and easy ride.
