The positioning of Gas Motorcycles range extender should not be compared with oil-powered motorcycles, but should be positioned as an emergency device, so:
1) The volume does not need to be large, it should be as small as a hat, and can be placed in the seat bucket or trunk, which is convenient for use and does not need to worry about theft. If it is winter, it can be placed in the seat bucket, which is quiet and can warm the buttocks. In summer, it can be placed on the pedal.
2) The weight does not need to be too heavy, it should be within 10 kilograms, so that it will not cause too much pressure on the Gas Motorcycles.
3) The output power does not need to be too high, 500 watts is enough, the speed does not need to be too fast, it can be used for 30 yards, after all, it is used occasionally, why run so fast?
4) The fuel tank does not need to be large, one liter is enough, assuming the fuel consumption is 3 liters, one liter can also run 30 kilometers, which is enough for emergency. Even if it is not enough, it can be added on the road, and it can handle within 100 kilometers. What about more than 100 kilometers? Frankly speaking, Street Motorcycles are not suitable. Compared with cars, they are slower and less comfortable. It is too tiring to travel long distances. People are unwilling to drive when cars can.
5) The price does not have to be very expensive, within 500 yuan. After all, you will use it less, and it is not worth spending too much money.
