Versatile ISOFIX & 4-Child Seating Capability

The Dynamic Cargo 3 is one of the most flexible family freighters on the market, offering the ability to transport up to four children with the addition of an optional second bench. For those with younger infants, the cabin can be fitted with ISOFIX mounting brackets, enabling the direct and secure installation of a standard car seat. This makes the trike a truly future-proof investment that adapts as your family grows, from infancy through to the primary school years.

Intelligent Cargo Switch Anti-Tilt Technology

Safety is redefined with the Cargo Switch true anti-tilt system, a smart feature that significantly enhances stability during cornering. This technology automatically monitors the trike's movement and adjusts the motor output when turning to prevent tipping and ensure the wheels remain firmly planted. It provides the rider with a much more intuitive and "dynamic" handling feel, allowing for confident manoeuvring through tight urban streets and around sharp bends.

Shimano CUES 9-Speed Drivetrain & Hydraulic Brakes

To manage the mechanical demands of a cargo trike, Humber has fitted the high-performance Shimano CUES 9-speed drivetrain, known for its durability and smooth shifting under load. This is paired with Bengal Ares hydraulic disc brakes featuring 180mm rotors on all wheels, providing massive and consistent stopping power. The inclusion of a dedicated parking brake ensures the trike remains completely stationary during loading and unloading, even on uneven or inclined surfaces.
