자전거 사이클링 스포츠 로고 프롬프트 바퀴와 번개를 합친 사이클링 로고

Use case: logo-brand. Create one original cycling-brand symbol: a bold circular wheel ring with a clean diagonal lightning-bolt cutout flowing through its center and breaking the ring at two intentional points. The bolt must read through negative space, with no separate overlapping icon and no thin spokes. Use [심볼색] solid shapes on a [배경색] background. Sporty compact geometric silhouette, deliberate slightly forward dynamic, controlled equal ring thickness, no bicycle illustration, lettering or speed-line decoration. A single centered symbol only, occupying about 55 percent of a square 1:1 canvas, with generous clear space. Flat vector-like graphic appearance, solid ink shapes, precise edges, optically balanced negative space and a silhouette that stays legible when small. No lettering, words, slogan, mockup, stationery, perspective, gradients, texture, shadows, 3D, watermark, border or multiple variations. This is a raster logo concept image, not a vector file. Generate one finished image.
