What is an E-scooter or E-Motorcycle?
An E-2-wheeler is a type of electric two-wheeler – a purely electric vehicle. It includes an e-scooter, e-motorcycle, e-moped, e-bike, or e-bicycle. It neither has an engine nor uses fossil fuels such as petrol, diesel, or CNG to run. Instead, it uses only electricity to power and runs itself. It has a rechargeable battery to store the electric energy and uses it to propel the 2-wheeler or. So, you can say that a 2-wheeler that uses only electricity to run is called the E-2-wheeler, E-scooter, or E-Motorcycle.
- Hub motor
- Electric Throttle / Accelerator
- Control panel / switches
- Charging device / Fast charger
- Digital display
- Pedal Assist Sensor (PAS) in e-bicycles
- Battery Management System (in some e-scooters)
How an E-scooter or E-Motorcycle works?
An e-scooter gets its power from the electric motor instead of an internal combustion engine. The DC battery provides current to the electric motor, which sits inside the wheel hub. Manufacturers call this set up as ‘Hub-Motor.’ Usually, the hub motor is a part of the rear wheel. The hub motor also features either a drum or disc to hold braking system components. Thus, it is a compact unit that has motor and braking system parts assembled into one unit.
The cable for supplying the electric current to the motor comes out from the center of the hub. It connects to the battery thru a controller and an electric throttle/accelerator. When you put on the ignition, the electric current flows from the battery to the hub-motor thru’ controller and electric throttle. The current increases when you increase the accelerator, and the hub motor starts to spin, moving the e-scooter forward. However, most E-scooters don’t come with transmission or gears. Thus, reducing the weight and cost of manufacturing the scooter. Instead, the motor itself has variable speeds that you can control thru electric throttle.
Also, there are riding modes such as Eco, Power, and Sport for different types of performances. However, the battery range differs depending on the riding mode. For example, in the Eco mode, your e-scooter will go more miles than the Sport mode. However, Eco mode will restrict the speed while Sport mode will deliver maximum speed but low mileage. Therefore, the E-scooters or E-Motorcycles are in no way less than the conventional scooters in terms of power, speed, and acceleration (pick-up). In addition, most e-scooters offer a unique feature of 'reverse'. Since the motor itself spins in both directions, you can reverse the scooter for a short distance by engaging the 'reverse' switch.
The performance of an e-scooter mainly depends upon the wattage rating of the electric motor. The higher the wattage better the performance. E.g., the electric motor's power output hugely affects the load-carrying capacity and gradability of an e-scooter. So, be careful while choosing your next e-scooter. Low-wattage scooters could be cheaper to buy. However, they may not meet the expected performance levels. According to experts, better performance for carrying two passengers needs at least a 250W electric motor.
The e-scooter is still in the developing stage. Some battery manufacturers are working on further improving the fast-charging capabilities of batteries. Currently, many old and new scooter-makers are already working on their e-scooters. However, Gogoro, Ola, And Ather are some of the popular e-scooter manufacturers in the world.
