A better way to decide would be to get a test drive. It will give you a clear understanding of how both the electric scooters perform. Everything about the Ather's 450s feels amazing. Everything about it is sturdy and reliable including the range, brakes (disc brackes) and build quality. I faced zero to no problem transitioning to Ather 450 from a petrol scooter. Honestly, Ola's S1 pro feels bland. Ola's build quality is terrible. Ola's cons: Rattling brakes, handling issues, too much dependency on tech, unreliable, cheaply built (plastic everywhere), panel gaps everywhere, bad breaking performance, it heats easily, too many glitches and software problems. Overall a bad UX.👎 Ather is definately expensive but there's a difference of sky and earth between the two. Get a test ride for both and pick wisely.
