Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Electricity is stored in rechargeable batteries on board, which drive one or more electric motors. Electric scooters (unlike motorcycles) have a stepped frame.

The emergence of electric motorcycles is faster than we thought, and its benefits may outweigh the disadvantages of high purchase price, charging time and battery range. Sometimes professional electric Motorcycle companies and some traditional motorcycle manufacturers have electric bicycles or scooters on the market, or are waiting for the concept of entering the showroom.
In fact, the current cruising range has reached more than 300 kilometers, and 80% of the charging time has been shortened to 30 minutes.
But what are the benefits of electric motorcycles?
City cycling
Although some motorcycle tour companies, such as Eidelwiess in Europe, rent electric motorcycles, traveling is not their strong point.
In fact, riding in the city expands the use of electric motorcycles because they charge the battery through regenerative braking.
Long-term, sustained road cruising will actually restore the battery replacement.
Power and carbon dioxide
The most important thing for riders is that electric motorcycles are fast.
Electric cars hold the record of cars and bicycles on Pixar Peak.
The motor has an instantaneous 100% torque, which means rapid acceleration.
The only drawback is that the power transmission method is linear, and there is no feeling of "surging". Many drivers have experience with traditional fuel engines.
