The Tern Orox is an adventure-ready cargo bike. With the ability to go through or up about anything with the 27.5 x 4″ tires and also carry a pretty heavy load, this cargo bike really blurs the lines of what the bike is capable of doing and what the rider should be doing.

If you like going off-road with your cargo bike, check out the adventure cargo bike category, which includes the Benno Boost, Riese & Muller Multicharger, Surly Big Easy, and the Xtracycle Stoker.
