Build one centered mobile app icon around the Icon Concept for the App Type. Use the Style and Color Palette with a strong, instantly readable silhouette, crisp geometric edges, and comfortable padding inside the icon. Present it as a real iOS or Google Play app icon: a smooth rounded-square squircle with a solid or subtly controlled background, centered on a plain very light neutral background. The icon should fill about 70 percent of the square 1:1 canvas and cast a soft, subtle shadow beneath it. Keep the symbol simple, original, and legible at small sizes, using negative space intelligently. Do not show a device, hands, mockup, additional icons, variants, text outside the icon, letters, tiny details, thin lines, glow, sparkles, lens flares, photographic texture, watermarks, or any existing logo or mascot.
Use these details:
App Type: "Cycling app"
Icon Concept: "A speedometer dial with its arc formed by a bicycle chain"
Style: "Flat icon design"
Color Palette: "Black and orange"
