Who is this bike suitable for?

The Tern Orox S12 is the perfect companion for those seeking adventurous riding and the ability to tackle all terrains with ease. This cargo bike is designed for riders who want to explore new horizons, carry heavy loads, or simply enjoy a powerful and versatile ride.

With two frame sizes available, this bike can accommodate riders ranging from 155 - 195 cm (5’1” - 6’5”) in height. This cargo bike is EFBE-certified safe and reliable for heavy hauls, with a Max Gross Vehicle Weight of up to 210 kg (462 lb) on pavement and 180 kg (397 lb) off-road.

Whether you are an individual, family or business, the Tern Orox has an eco-system of accessories that can be tailored to suit your needs, be it carrying kids or cargo.

About the Tern Orox S12 Cargo Bike

With a Shimano Deore XT 1 x 12-speed groupset, you'll experience lightning-fast and precise shifting, ensuring smooth transitions between gears.

The custom 27.5" Schwalbe Johnny Watts all-terrain tires or 27.5" stud-compatible Vee Snowball tires provide exceptional traction on any surface, allowing you to confidently conquer even the toughest conditions.

It’s incredibly capable and well specced. It’s fun to ride. You can fix most of Tern’s huge range of existing accessories to it, and some new Orox-specific ones. It can carry more stuff off-road than any other bike we can think of. If you’re going to ride across the wilderness carrying fifty kilos of outdoor gear, then it’s hard to imagine a better bike for the job.
