Introducing the radical edition of Bündnerbike’s latest custom masterpiece — the “Bronx Brute.”

A bike reimagined from the ground up, reengineered with precision, and shaped with bold character in every curve.

Based on the Harley-Davidson Breakout, the original frame has been stretched, lowered, and widened to a whole new level through meticulous custom racking. What remains untouched is the powerful heartbeat of the 117ci Milwaukee-Eight V-Twin engine — everything else has been completely transformed.

The “Bronx Brute” stuns with its deep black and bronze chrome effect finish, paired with one-off custom wheels, a fully redesigned front fork, and hand-shaped bodywork. It’s a street-ready cruiser that carries the soul of a showbike — aggressive, legal in Switzerland, and unapologetically one of a kind.

Designed in the mountains, made for the city — the Bronx Brute brings raw power, refined craftsmanship, and unmistakable presence to the streets.

Technically complex. Visually unforgettable.
This finish isn’t just a color – it’s a statement.
