Yadea electric vehicles are better. Yadi electric vehicles are the leader in the electric vehicle industry, with good configuration and comfort. In particular, the battery and motor are very advantageous, and the overall design is also very favorable, and the price is acceptable. It is a good choice for an electric vehicle!
Yadea's batteries are light in weight, have large capacity, high energy density, long cycle life, and strong voltage output. Its capacity is 1.2-1.5 times that of lead-acid batteries of the same quality, and it has a very low self-discharge rate. The battery also adopts an advanced fully enclosed valve-controlled energy-saving design, making the battery maintenance-free and safe and environmentally friendly; the unique automatic under-voltage protection device can effectively avoid damage to the battery due to insufficient or excessive power, greatly extending the use of the battery. life.
The special motor for Yadi electric vehicles, the GE high-energy ultra-quiet motor, has no vibration or noise when starting and accelerating. By improving the weak magnetic field speed expansion capability, the dual high energy of speed and mileage can be achieved. The current output is stable, eliminating magnetization and demagnetization of the motor, reducing energy loss, improving power conversion efficiency, and extending battery life to 180 days.

Things to note when purchasing an electric bicycle
1. Pay attention to the electric bicycle logo, certificate, and date of manufacture. The marked product name should be "Electric Bicycle", and the certificate or tag should have "Production License", which is the QS certification mark; products that have been manufactured recently should be purchased, because the battery will be left standing for a long time, which will affect the actual capacity and cycle of the battery. Life span; read the instructions carefully to understand the product's technical parameters, performance indicators and three guarantees.
2. Pay attention to the product installation. To check whether there is a pedal device, the mass (weight) of the vehicle should be no more than 40KG, and the maximum speed should be no more than 20KM/H. Check the appearance of the vehicle. Parts with surface coatings such as paint and electroplating should be uniform in color and smooth. , there should be no cracks in the plastic parts; looking at the vehicle assembly, each fastener should be tightened, the rotating parts should run flexibly and should not collide with other fixed parts, and the symmetrical parts should be aligned with the left and right of the vehicle.
3. Don’t blindly pursue high power. The greater the power of an electric bicycle, the stronger the power, the greater the loss of the battery, and the shorter the service life of the battery, because long-term high-current discharge is the most damaging to the battery, and the cost of replacing the battery is also higher. In addition, electric bicycles with greater power have higher braking requirements.
