iruka is a transformer bicycle which changes its form into four modes to suit the scene. No tools are required to fold or unfold. Expand your mobility with the touch of a hand.
It’s a breeze.
Small wheels don’t mean a small ride. iruka’s 18-inch wheels propel you one and half times more than your average single speed commuter bicycle with a single pedal rotation in top gear. Precise gear ratio settings, a high rigidity frame that efficiently converts pedaling force to propulsive force, and a stable geometric design that ensures stability at high speed.
Optimized to be zippy.
Agility and flexibility are key when riding in cities, as well as speed. But with iruka you needn’t worry. The 18-inch wheels handles frequent starts-and-stops well, the Shimano internal geared hubs make it highly-capable for high-speed cruising or steep climbing, and the small rotor disc brake operates efficiently and effectively.
Compact. For impact.
iruka can be folded 30% smaller than ordinary folding bikes(*1). The perfect rectangular folded shape fits in a car trunk, on a train seat, under your desk, or any other space. And it easily fits a narrower space when stored vertically(*2).

Walk it. Roll it.
You may be thinking, even compact folded bikes are a pain to carry. And you’d be right. Except with iruka. Its front and rear wheels fold parallel and coaxially, which allows you to roll iruka like a carry cart. So metro concourses, airport terminals, and office hallways are no problem. iruka can go wherever you go. Now, where do you want to go?
Missing the kickstand? No problem. When you fold in iruka’s rear wheel, it acts like a kickstand. It becomes 2/3 its overall length, so you only need half the parking space of ordinary bicycles.
Strength + Beauty
In order to achieve the distinct aesthetic of the iruka frame, we began by creating metal molds for nearly all the frame components. For the frame, we selected 6061 aluminum alloy for its strength and light weight, to achieve an excellent balance between eye-catching beauty and strength that passes the EN/JIS Standard Strength Test*.
