There are many ways to convert a bicycle into an electric bicycle. Adding a motor and a large lithium battery is the simplest and most direct method, but the bicycle itself will become very heavy and heavy. Ugly. A German company called "Velogical" has designed a mini motor that weighs only 1.6 kilograms. Fix it on the front and rear forks of the bicycle. Once the motor switch is turned on, the driving wheels on both sides will automatically stick to the tire hub, thereby driving the tires to rotate. It is light and does not affect the appearance of the entire vehicle. The built-in 92-watt-hour lithium battery can drive continuously for 20 kilometers and can output a maximum power of 600W. When the motor switch is turned off, the driving wheel will automatically deviate from the tire hub. This design can greatly extend the service life of the driving wheel. The product is still in the trial production stage, and technical problems such as high noise have yet to be solved.
