To improve the mileage of the Ather 450X Gen 3, it is crucial to optimize your riding mode and style. Use the Sports mode for speeds between 40-60 km/hr, as it can provide a range of up to 98.2 km, which is closer to the scooter's 'True Range' claim. For maximum range, use Eco mode, which can deliver up to 115.5 km. Avoid achieving the maximum speed in any mode, as this significantly reduces battery life. Maintaining optimal tyre pressure and riding at speeds between 25-40 km/hr can also help regenerate battery charge, adding up to 5 kilometers to your range. Additionally, aggressive use of regenerative braking, especially below 20 km/hr, can enhance efficiency. By riding at moderate speeds and utilizing the appropriate mode for your commute, you can achieve a real-world range of 105 km or more with the Gen 3's larger 3.7kWh battery pack.
