Create a stationary product demonstration of a fictional electric bicycle dashboard. Preserve the compact circular display from Image 1 and the left-handlebar three-button control from Image 2. Bicycle is secured on an indoor service stand; no riding occurs.

Opening macro: display wakes from black to the approved neutral home state. A gloved thumb presses the lower button once; the interface changes from “ECO” to “CITY” following Image 3, with a short amber transition. A second press changes “CITY” to “HILL” with a restrained red accent. Camera shifts focus from thumb to display while the rest of the handlebar remains still. End by holding the complete HILL state for human-added explanation.

Preserve button count, screen geometry, supplied labels, and one-to-one input response. Sound intent: tactile button clicks and quiet workshop tone. Avoid speedometer movement, motor activation, invented range numbers, extra icons, riding footage, warped hands, third-party logos, or watermark.
