Description
Just the right size cargo bike for urban living
Based in Copenhagen, Denmark, OMNIUM is a brand that manufactures fast, lightweight and practical cargo bikes specialized for transporting and moving goods.
The OMNIUM Nano is the most compact cargo bike in the OMNIUM lineup. With 20-inch (406) wheels front and rear and a short wheelbase, it delivers sharp acceleration due to its small diameter and a nimble ride with a small turning radius. Despite its small size, the cargo bike's load capacity is well maintained, with a maximum front rack capacity of 40 kg and a total load capacity of 125 kg including the rider. It expands the range of proposals for customers who live in condominiums or wish to store the bike indoors.
Adjustable rocker dropouts accommodate a variety of drivetrains, from exterior gears (1x) with derailleurs to interior gears and single speeds. Interchangeable inserts allow you to choose the rear end width and brake mount standard to your liking.
NANO shares many standards with other models, allowing you to use compatible accessories without modification. A special bracket is also available that allows you to tilt the rack when parking the bike to further reduce the width of the vehicle. Plans call for the future expansion of dedicated accessories, such as a NANO-specific foldable storage box and rack extension parts.
We believe that the Omnium is a bike that is full of fun and playfulness, and will make the future around us brighter and more enjoyable.
*This product is sold as a frame set.
*This type of rear end comes with dropouts for 135mm QR. 12x142mm thru-axle is available upon request.
