    What is electric motor for bicycle

    Electric motor for bicycle is the most important accessory for electric bicycles. Electric motor for bicycle basically determines the performance and grade of this car.

    Electric motor for bicycle is a component that converts battery electrical energy into mechanical energy to drive the rotation of electric wheels. For electric motor for bicycle, there are many types of mechanical structure, speed range and energization form.

    What are the types of electric motor for bicycle

    Hub motor

    The electric motor for bicycle is integrated inside, and when energized, the motor converts electrical energy into mechanical energy, which drives the wheels to rotate and drive the vehicle forward.

    Usually designers install in-wheel motors on the rear wheels, especially sports models. Because compared to the fork, the rear triangle is more stable and reliable in terms of structural strength.

    With mature design solutions and relatively low prices, in-wheel motors occupy most of the majority of electric bicycles.

    However, since the motor is integrated into the wheels, it will break the front and rear weight balance of the whole vehicle. At the same time, it is greatly affected by bumpy impacts when off-mountain off-roading.

    There are two types of hub motors: toothed motors also known as gear motors (usually planetary gear designs) and toothless motors also known as direct drive motors.

    What are the types of electric motor for bicycle

    • Gear motors

    Planetary gears act like levers in motors, reducing the speed and amplifying output torque, so that the compact and lightweight motor can also have a strong power output.

    • Gearless hub motor

    The internal structure is relatively traditional, there is no complex planetary reduction device, and it directly relies on electromagnetic conversion to generate mechanical energy to drive the vehicle.

    Gearless hub motors may not have a clutch inside them, so magnetoresistivity needs to be overcome when riding without power. But because of this, the hub motor of this structure can realize kinetic energy recovery, that is, when going downhill, kinetic energy is converted into electrical energy and stored in the battery.

    Mid-mounted motor

    In order to achieve better athletic performance, high-end mountain bikes usually use a mid-mounted motor scheme. The mid-mounted motor, as the name suggests, is a motor placed in the middle of the frame (at the chainring).

    According to the installation method, the central motor is divided into two types: frame integration and external suspension type. According to the structure and shape of the motor, it can be divided into coaxial central motor and parallel shaft central motor.

    The advantage of the electric motor for bicycle is that it can maintain the balance of the front and rear weight of the vehicle as much as possible, without affecting the action of the shock absorber.

    Mid-mounted motor

    The best electric motor for bicycle mid-motor system needs to:

    • Fast power response

    If there is a delay in pedaling, it will have a big impact on the pace of the ride.

    • Precise output power

    The output changes between different gears should be linear to improve the riding experience.

    • High torque

    The internal clutch gear combination achieves a torque amplification effect, and higher torque can be obtained whether riding on a flat road, climbing a hill, or under load.

    • Low energy consumption

    Increase battery life with a larger battery pack.

    • Low presence

    Ride quietly and smoothly, with less maintenance at a later stage.

    Why the electric motor for bicycle is mounted on the rear wheels

    This phenomenon is not only present in electric bicycles, but also in electric motorcycle and other similar vehicles. Why is the electric motor for bicycle on the rear wheels?

    The vehicle’s center of gravity

    First of all, we need to understand the center of gravity of electric vehicles.

    As we all know, the center of gravity of an electric vehicle plays a crucial role in its driving. Since the position sitting in the car is forward, and most electric vehicle batteries are also installed in the front position, this results in the overall center of gravity of the vehicle being in front.

    If the electric motor for bicycle is also installed on the front wheels, it will further burden the front of the car, causing the center of gravity of the electric car to shift even more forward.

    At high speeds or cornering, this can lead to poor handling of the vehicle, increasing the risk of rollover and collision. By contrast, mounting the electric motor for bicycle on the rear wheels effectively shifts the vehicle’s center of gravity back.

    Why the electric motor for bicycle is mounted on the rear wheels

    This way, even if the motor weight is large, it will not affect the balance of the vehicle too much. In addition, the rear-wheel drive design makes the vehicle more stable during driving, reducing the possibility of accidents due to improper handling.

    Secondly, the installation of the electric motor for bicycle on the rear wheels facilitates better control of handlebar direction.

    Installing electric motor for bicycle on the rear wheels avoids this problem, as the load on the rear wheels is relatively light, making it easier to steer and thus improving driving stability.

    In addition, the current electric motor for bicycle power on the market is generally large. If the motor is installed in the front wheel, it will cause the power output of the electric vehicle to be too fast and lack cushioning.

    When the electric motor for bicycle starts or accelerating, it may suddenly burst, which is a safety hazard for drivers and other road users.

    When the motor is installed on the rear wheel, a slow starting process is formed due to the resistance of the front wheel, which reduces the risk of accidents.

    Braking effect

    In addition, we cannot ignore the design of the braking system for electric vehicles.

    Many electric vehicles like electric dirt bikes have a rear brake configuration, which means that the front wheels are equipped with disc brakes and the rear wheels use drum brakes. This is designed to better control the speed and provide braking power.

    However, if the front wheels also bear the weight of the electric motor for bicycle, it will increase the burden on the braking system and accelerate brake wear. The drive design reduces the burden on the front wheels and extends the life of the brakes.

    To sum up, the electric bicycle motor is installed on the rear wheel instead of the front wheel for a variety of reasons.

    The rear-wheel drive design helps to maintain body balance, improve driving stability and reduce the risk of accidents, while also helping to control handlebar direction and reduce the burden on the brake system. Together, these factors determine the optimal mounting position for electric vehicle motors.

    What to pay attention to in the maintenance of electric motor for bicycle

    Electric bicycles are lightweight and convenient, which can be used in everyday life or for a short trip. However, in daily use, if the maintenance is neglected, the life of electric vehicles will be greatly reduced.

    What to pay attention to in the maintenance of electric motor for bicycle

    Poor vehicle conditions can also easily cause safety accidents and endanger the life and property safety of cyclists. Electric motor for bicycle is the “heart” of electric vehicles and is directly related to the power of electric vehicles.

    The electric motor for bicycle inspection focuses on the bearings and rear forks to ensure that they are operating properly. No special maintenance is generally required during normal use.

    Usually pay attention to check the fastener status of the motor hub shaft end and the motor end cover, if you find that there are screws or nuts loose, you should tighten them on time.

    Prevent vehicle failure due to twisted lead wires, etc., which will affect the safety of use. When the electric bicycle moves backwards, it feels that the rear wheel is heavier backwards, which is normal.

    When the electric vehicle feels a lot of resistance when it is pushed forward, first disconnect the power of the electric motor for bicycle, and then carry out maintenance on time. At that time, BENLG is ready to offer solutions.

    Conclusion

    Electric motor for bicycle is the core device of the car, and understanding the structure and performance is the basis for better maintenance of electric vehicles. The motors used on electric bicycles are DC motors, and brushed DC motors and brushless DC motors have been used successively.

    As consumers and drivers, understanding and paying attention to the design and performance characteristics of electric motor for bicycle is important for us to better use and maintain our vehicles.
