A versatile cargo bike that shines in the city
Based in Copenhagen, Denmark, the OMNIUM brand manufactures lightweight, fast, and stable cargo bikes for carrying, moving, and traveling.
The Minimax is designed on the premise that both front and rear tires are 55 mm (2.15″) front and rear, and the suspension effect of the air volume improves comfort and control. Combined with a through-axle for large loads and new high-performance dropouts, this is the ultimate cargo bike with versatility as its top priority.
Adjustable rocker dropouts allow a variety of drivetrain choices (though not simultaneously), from exterior gears with derailleurs to interior gears or belt drive. They can also be configured with fixed gears. Interchangeable inserts allow you to choose between through-axle and quick-release, depending on the end width of your rear hub and choice of gear components. If needed, a spare set can be carried for easy replacement of broken rear hangers.
Replacement drop-out inserts can be ordered here.
The Mini Max is an in-between model that seems to combine the advantages of the Cargo and Mini models. Its shorter wheelbase makes it handle more like a regular bike, with improved maneuverability.
The front rack is one size smaller than that of the Cargo, but an extender bar can be added to provide ample carrying capacity.
The front wheels are positioned near the center of the front rack, which improves steering and handling performance, but may be slightly less stable than the Cargo when loaded with heavy loads.
The Minimax is best suited for those who value smoother handling and tight parking spaces and do not always need maximum carrying capacity.
Blurple and Black are available with a ¥22,000 upcharge.
