According to the manufacturer, the ST E3 has a range of approximately 120 km (74.6 miles) on a single charge while traveling at a constant speed of 35 km/h (21.7 mph). Maximum speed is estimated at 60 km/h (37.3 mph).
Hyosung also says the ST-E3 features Korea's first built in VFD (Vacuum Fluorescent Display), which allows the rider to read battery status, scooter body condition, and drive condition, simultaneously. The adoption of the MCU (Motor Control Unit) constantly checks overcharge and over-current and adjusts for premium conditions.
“Producing electric scooters by S&T Motors represents a lot to the new eco-friendly business. We’ll support this business as a Green Development Business with New & Renewable Energy,” stated Kim Do Kwan, governor of GyeongSangNam-Do.
"Producing eco-friendly electric scooters without noise and pollution means a lot to the Korean Green Development Business for S&T Motors," added Park Wan Soo, mayor of ChangWon City.
ChangWon City will promote the electric scooter by hosting the company flag on the main street of the city, displaying it on the billboard sized electronic display at the City Hall of ChangWon, and by placing the product in the local ChangWon newspaper.
Hyosung will launch the ST-E3 in United States, Canada, and South America. The company has also announced plans to produce more electric models in the future, including 2.5kw and 4kw level eco-friendly vehicles.
