Tern Orox S12 27.5

Go Anywhere

The Tern Orox is a 4-season adventure cargo bike ready for anything.

Traditional cargo bikes face limitations on unpaved roads, while off-road bikes struggle to carry substantial cargo. The Tern Orox brings cargo bike utility to any type of terrain. With large-volume tires and a powerful Bosch motor, Orox offers excellent traction and comfort on the most challenging surfaces. Whether it’s negotiating poorly maintained urban streets during the week or heading out for a weekend overnight at a remote lake, Orox can handle it all.

Combining the ruggedness of a mountain bike, versatility of a trekking bike, and utility of a cargo bike, Orox provides riders the freedom to craft their own unique experiences.

Go Any Time

Orox won’t let nasty conditions get in the way of a good adventure.

Extra-wide tyres work in most conditions; but if extreme conditions require special tyres, Orox’s frame and fork are designed to let riders swap in their choice of 26 x 5”, 27.5 x 4” or 29 x 3” wheels/tyres. Heavy-duty mudguards keep rider and bike clean(er) when things get sloppy, while the Frame Pack insulates the battery for optimal performance when the temperature drops.

Ride on snow in winter, mud in spring, sand in summer, or off-road terrain when camping in the fall. Orox is always ready to roll.

Bring it All

Orox is a heavy-duty hauler with a max gross vehicle weight capacity of 210 kg (462 lb) on-road and an unmatched 180 kg (397 lb) off-road. Urban riders can seamlessly transition from an effortless morning school run to a fun date-night ride along a favorite river trail. Adventure seekers can extend backcountry excursions by bringing more supplies, or pamper themselves by packing extra comforts such as a favorite cast-iron skillet, an extra tackle box, or even a cooler full of ice-cold beverages.

A full selection of Tern accessories lets riders deck out their Orox rig to fit their unique adventuring needs.

Inclusive Design

The Tern team took special care to design Orox to fit a wider range of riders. Special adjustments to frame geometry and component choice allow the Large size frame to fit riders up to 195 cm tall and 130 kg in weight. On the smaller side of the spectrum, the Medium size Orox frame fits riders from 155 cm tall, thanks to a mid-step frame design.

Built for Work

Orox is an ideal vehicle for organisations and businesses that need to move people and gear to tough-to-reach places. Whether that’s chainsaws and shovels for trail maintenance workers, medical equipment for EMTs at concert venues and sporting events, or safety equipment for first responders, Orox is built to get the job done. Businesses interested in Orox can research use cases and contact Tern at bikesforbusiness.com.

Safety Matters

The importance of safety can’t be overstated for a vehicle designed for hard outdoor usage in remote areas. Ensuring that all load-bearing components meet off-road bike safety standards for a high rider weight plus cargo simply ruled out many conventional bicycle components. The next challenge is completing the many rounds of testing with cargo loads not seen on typical mountain/downhill bikes. EFBE Prüftechnik in Germany performed the structural testing on Orox using their rigorous Tri-Test standard. Choosing Bosch for the motor and electrical system ensures UL compliance and the highest level of safety and reliability — important when you’re many miles into the backcountry.
