Biwakoguma Bicycles: Out of this world
Biwakoguma Bicycles from builder Tsuyoshi Ishizu turned heads this year at NAHBS with a bike called "Galaxy" that featured a Jackson Pollock-inspired paint scheme.

Tsuyoshi Ishizu is the man behind Biwakoguma Bicycles, and he brought a bicycle named “Galaxy” (and nicknamed “UFO”) to his New Builder table at NAHBS this year. The bike’s paint scheme was inspired by American artist Jackson Pollock’s “action painting” style.
Ishizu built this bike for a Japanese friend and used Kaisei 019 steel tubing. The bike is suited for long-distance rides, with classic road bike geometry. Ishizu used chrome-plated polished lugs, a curved bend front fork with traditional threaded steerer tube, and triple-triangle style curved bend seatstays.
Here are the design details:
Top tube length: 560mm
Seat tube length: 550mm
Head tube angle: 72.1 degrees
Seat tube angle: 73.8 degrees
Fork rake: 48mm
BB drop: 70mm
Wheelbase: 1010mm
Chainstay length: 410mm
Maximum tire clearance: 28c
Ishizu orchestrated and performed complete production of the frame, from design to its attention-getting paint scheme, which involves gold and silver leaf accents. He calls the complete paint scheme “UFO flying galaxy”.
The catalog introducing Jackson Pollock’s first exhibition called his talent “volcanic. It has fire. It is unpredictable. It is undisciplined. It spills out of itself in a mineral prodigality, not yet crystallized.”
While the same might be said of the Galaxy’s visceral paint job, clearly the bike's overall craftsmanship is grounded in the great tradition of Japanese precision and highly disciplined frame building.
