Classic Japanese Bicycles
Iribe produced some of the most meticulously crafted track bikes ever to grace the banked surfaces of Japanese競輪 (keirin) racing circuits. When discussing elite Japanese track bicycles, most
enthusiasts immediately think of Nagasawa, 3Rensho, or Makino. Yet lurking in the shadows of Japan’s storied NJS certification ecosystem exists the Iribe. This manufacturer frames are whispered about in keirin velodroms with reverence.

The Lexus NXB concept bike represents a technical achievement in bicycle engineering. This collaboration between automotive and cycling technology debuted at the Tokyo Motor Show alongside the LF-NX Turbo concept. The NXB demonstrates how carbon fiber manufacturing from supercar production translates to two-wheeled performance. Consequently, this mountain bike concept showcases the same carbon fiber loom technology used in the Lexus LFA supercar, creating a rigid yet lightweight frame structure.
