The control method of the electric scooter is the same as that of the traditional electric bicycle, which is easy to be learned by the driver. It is equipped with a detachable and foldable seat. Compared with the traditional electric bicycle, the structure is simpler, the wheels are smaller, and the wheels are lighter and simpler, which can save a lot of social resources. In recent years, the rapid development of lithium battery electric scooters has spawned new demands and trends.

What factors will affect the endurance of electric scooters?
How to distinguish between a sine wave and square wave control of mobility scooter?
How to choose tires for a mobility scooter?
Only in terms of software and hardware, it does not include the factors of the user and the use environment. Four key points affecting battery life: battery capacity, motor power, motor control method, and tires.
1) The battery of an electric scooter: The battery has the greatest impact on battery life. It is strongly recommended to buy a scooter that uses imported batteries. First, the battery conversion rate and energy density are higher, that is, the imported battery capacity is larger under the same volume and weight. At present, the single capacity of domestic batteries is 2000 or 2200, and the single capacity of imported batteries is 2600 or 3200, which is equivalent to 30% more battery life. The second is safe and secure. At present, there are too many examples of spontaneous combustion and explosion of scooter balance vehicles, all of which are caused by the use of inferior batteries.
2) Motor power of electric scooters: the greater the power, the better, there is too much waste, and too little is not enough. At the same time, the power selection of the hub motor is also related to the wheel diameter, speed, torque, and so on. Take a scooter with a wheel diameter of 8 inches as an example. The motor power can be in the range of 250W~350W. Each motor has an optimal power range. This is related to the output curve of the motor. The output power of the general cruising speed is just in this optimal range. inside.
3) Motor control mode of electric scooter: square wave control and sine wave control have their advantages and disadvantages. Swing wave control is comfortable, linear acceleration, high cost, low power consumption, and low sound. Square wave control is simple and rude, cheap and stable, accelerating straight, starting rush, cruising, and power saving. Generally, it is recommended to use sine wave control products. A good sine wave control product has higher requirements for the technical capabilities of the enterprise and pays more attention to the user experience. The overall energy utilization efficiency is 5 to 7% higher than that of square wave control.
4) The tires of electric scooters: the driving wheel has high friction and the driven wheel has low friction and high endurance, and vice versa.
Sine wave control is to turn the handle slightly under no load. At this time, the motor starts softly and smoothly and continues to accelerate to the highest speed. Under load, it starts softly without rushing, and there is no abnormal noise, quiet and comfortable; while the square wave controller is quiet and comfortable. When the handle is rotated a little under load, the motor will accelerate a little. Under load, there will be a lot of noise at the start, and the start is more aggressive, so it is not suitable to be manipulated.
The mainstream mobility scooter on the market has a two-wheel design, some of which are three-wheel designs (front three wheels or rear three wheels). Two-wheel design is recommended, which is flexible, safer in turning, cheap and reliable (the price of fewer wheels and suspension structure), Lightweight and compact. The wheel diameters are 4.5, 6, 8, 10, 11.5 inches, and the common ones are 6, 8, 10 inches. It is recommended to choose large wheel diameters, such as 8 inches and 10 inches, which have high safety passing and good steering. Because the smaller the wheels of the mobility scooter, the easier it is to fall when turning. There are 4 types of tires at the same time, solid tire, honeycomb solid tire, tube-type pneumatic tire, tubeless tire (tubeless pneumatic tire). It is not recommended to choose pneumatic tires for small wheel diameters. It is too easy to burst. It is recommended to choose pneumatic tires for 8 inches and above. The shock absorber through pneumatic tires does not require additional mechanical shock absorbers. Here is a point to note, pneumatic tires must be selected tires The width is more than 40, don't choose too narrow.
It is the responsibility of each manufacturer to produce mobility scooters that meet the standards, to ensure the safety of travel and the healthy development of the scooter market. Wisking healthcare Corporation. has conducted many tests on mobility scooters before they leave the factory, and the quality qualification rate is guaranteed. If you are in the mobility scooter business, you can consider our cost-effective products.
