Geared hub motors are a popular choice for electric bicycles, scooters, and other small electric vehicles. These motors are compact, efficient, and relatively simple to install, making them a convenient option for many consumers. However, one question that often comes up when considering a geared hub motor is: just how heavy are they?
To answer this question, it's important to first understand what a geared hub motor is and how it works. A geared hub motor is a type of electric motor that is designed to be integrated into the hub of a wheel. This allows the motor to drive the wheel directly, without the need for a chain or other mechanical transmission.
Geared hub motors are typically smaller and lighter than other types of motors, such as mid-drive motors or outboard motors. This makes them a good choice for small electric vehicles, where weight and size are important considerations. However, the weight of a geared hub motor can still vary quite a bit depending on the size and power of the motor, as well as the materials used in its construction.
In general, geared hub motors tend to weigh between 2 and 6 kilograms (4.4 to 13.2 pounds). The smaller and less powerful motors will be on the lighter end of this range, while larger and more powerful motors will be heavier. For example, a small, 250-watt geared hub motor might weigh around 2.5 kilograms (5.5 pounds), while a larger, 750-watt motor could weigh up to 5 kilograms (11 pounds).
It's also worth noting that some geared hub motors are built with lightweight materials, such as aluminum, which can help to reduce their overall weight. However, these types of motors may also be more expensive than their heavier counterparts, which are typically made from steel.
So, how does the weight of a geared hub motor compare to other types of electric motors? As mentioned earlier, geared hub motors are typically smaller and lighter than mid-drive motors and outboard motors. Mid-drive motors, which are mounted to the frame of the electric vehicle and drive the chain, can weigh anywhere from 3 to 10 kilograms (6.6 to 22 pounds), depending on their size and power. Outboard motors, which are mounted externally to the wheel, can be even heavier, weighing up to 15 kilograms (33 pounds) or more.
It's also worth considering the weight of the battery and other components when evaluating the overall weight of an electric vehicle. The battery is typically the heaviest component in an electric bike or scooter, with many models weighing in at over 5 kilograms (11 pounds). When combined with the weight of the motor, frame, and other components, the total weight of an electric vehicle can range from 20 to 30 kilograms (44 to 66 pounds) or more.
In conclusion, the weight of a geared hub motor can vary significantly depending on the size and power of the motor, as well as the materials used in its construction. On average, geared hub motors tend to weigh between 2 and 6 kilograms (4.4 to 13.2 pounds), making them lighter than other types of electric motors such as mid-drive and outboard motors. However, it's important to consider the weight of the battery and other components when evaluating the overall weight of an electric vehicle.
