Belgian mechanical engineer and shed-builder Bernard Mont has unveiled “De Chaos,” a visually arresting hub-steered boardtrack-style machine centered around a 650cc BSA A65 “Power Egg” twin.
Born from a desire to evolve the innovative hub-center steering frame design of his previous “Nowhere Faster” sprint bike, the project was solidified following a chance collaboration with artist Roland Groteclaes, who helped crystallize Mont’s mechanical concepts into a cohesive artistic vision.

The build features a one-off oil-in-frame chassis with flowing, organic curves that mirror the rounded engine casings and custom exhaust pipes. Named for the global pandemic during which it was conceived, “De Chaos” represents a six-year labor of love that merges race car engineering precision with a minimalist, museum-quality aesthetic.
Technically, the bike is a masterclass in bespoke fabrication, featuring a homemade Difazio-style hub-center steering system paired with 21-inch rims laced to a Ducati rear hub.
The engine was completely rebuilt by Mont and outfitted with electronic ignition and dual Amal carburetors, while the minimalist aluminum tank and seat were hand-shaped in foam before being brought to life by metal-master Bart Geerts.
Every detail is meticulously considered, from the vintage racing bicycle handlebars modified for the unique steering setup to the suede-upholstered seat and extensive speed-drilled accents throughout the frame and engine casings.
While primarily designed as a stunning piece of mechanical art, the 55-horsepower machine is slated for its first ride in the spring, standing as a testament to the beauty that can be forged from periods of uncertainty.
