The 2020 Ather 450X was designed and built in India; it was first manufactured in Ather Energy's Bengaluru plant before being expanded at its Hosur, Tamil Nadu, plant, which started production in early 2021. Its precision-machined hybrid chassis strikes a compromise between lightweight stiffness, crash safety, and battery shielding by integrating cast-aluminium main frame components with selective high-strength steel reinforcing. With the 2.9 kWh/21700 cell pack enclosed within a Tesla-inspired aluminium structure integrated in the frame for enhanced thermal and impact protection, the chassis design also serves as the battery casing. Sharp, contemporary style and panelwork are highlighted by flush-fitting body panels, a lattice-exposed aluminium trellis frame that is visible beneath the seat sections, and streamlined LED lighting (tail, headlights, and indicators) that combines durability and minimalism. At debut, the fit-and-finish received recognition for its high-end details like aluminium mirror stalks and number-plate brackets, clean edges, matte paint options (especially Space Grey), and sturdy construction. Reviewers pointed out that the scooter's thick aluminium safety margins contribute to its relatively heavy curb mass (~108 kg), but this was done on purpose to preserve the NMC battery chemistry and improve structural stiffness without sacrificing manoeuvrability.
