Bespoked 2025 Concept Bike: Outback Xplore GT II + Mule

Tout Terrain Outback Xplore GT II expedition concept bike with Mule trailer at Bespoked 2025

Unveiled at Bespoked 2025 in Dresden, Germany, this Outback Xplore GT II concept represents everything we believe a modern expedition bike should be: self-sufficient, reliable, and ready for whatever the road throws at it.

Designed for long-distance riders who venture far from civilization, it combines robust engineering, intelligent details, and autonomous power supply — then pairs it with a matching Mule trailer for serious load-carrying capability.

Built for the big journey

The Stratocrom CrMo steel frame with the TBA III tensioning system is stable, durable, and engineered for high loads. The Pinion C1.12i Smart.Shift gearbox with Gates Carbon Drive belt delivers low-maintenance propulsion and precise electronic shifting — regardless of weather or terrain.

Electronic shifting precision meets proven Pinion gearbox technology. The C1.12i offers 12 evenly spaced gears and — combined with the belt drivetrain — maximum maintenance freedom. This is the drivetrain for riders who can't afford a mechanical failure days from the nearest bike shop.

The matching Mule trailer extends your expedition range without compromising handling. Equipped with its own hub dynamo, integrated lighting, a Ladeplug Plus for autonomous power, and a suspended single-wheel design, it carries gear securely even on rough tracks — and detaches in seconds when you want to ride light.
