HOW I ROLL CHAMP | A Single-Speed Bike Bringing Keirin Culture to the Modern Street
A natural blend of respect for keirin racing and modern street style.
Inspired by keirin, Japan’s unique form of track cycling, the HOW I ROLL CHAMP captures the distinctive character of a traditional keirin frame while remaining practical and easy to handle in the city. Its steep head angle, slim silhouette, and classic front fork all contribute to its authentic track-inspired appearance.
The DROP BAR version comes equipped with an NJS-certified Nitto B123 Steel 380mm handlebar. Its deep drop and elegant curves give the bike the unmistakable presence of a classic keirin machine.
The FLAT HANDLE version, meanwhile, offers a more relaxed riding position for casually cruising through the city. Being able to choose the setup that best suits your lifestyle and riding style is part of the CHAMP’s appeal.
The double-threaded rear hub supports both fixed and freewheel setups, allowing you to enjoy the direct feel of a fixed-gear bike or the easygoing character of a conventional single-speed. While the complete bike has a carefully considered and cohesive style, it also leaves plenty of room to personalize the handlebars, saddle, pedals, and other components.

Complete bikes with genuine respect for keirin culture have become increasingly rare, but the CHAMP feels like a model that has been properly thought through. The DROP BAR version is especially impressive, as it comes standard with the NJS-certified Nitto B123. Its distinctive deep curve feels special the moment you place your hands on it.
The smooth, responsive ride of the 4130 chromoly frame is equally enjoyable, giving the bike a unique sense of lightness even when simply cruising around town. The FLAT HANDLE version has a more casual character and is particularly well suited to commuting and everyday use.
Rather than being a pure competition keirin bike, the CHAMP strikes an excellent balance as a fixed-gear bike designed for enjoying keirin culture on the street.
