FUMA is the fat e-bike that put ROCKA FLAME on the map, reengineered for effortless city life. Its low step-through frame means anyone can hop on in seconds — skirt or no skirt, no awkward swing-your-leg-over moment. Plush fat tires soak up Tokyo's pavement and cobblestones alike for a smooth, almost floating ride, while the 350W motor (type-certified, license-free) climbs hills without breaking a sweat. The redesigned aluminum frame trades bulk for a sleeker, more modern silhouette, with a front basket ready for your day's shopping or camera bag. FUMA doesn't just get you across the city — it makes the crossing feel effortless, and looks good doing it. FUMAはFat Bike のフレームを使用した太いタイヤを履いている、バイクのような感覚のeBike です。是非、東京の街をストリート感覚で自由に街を走行してください
