Solar-powered wildlife conservation
& improved anti-poaching efforts

Solar-powered wildlife conservation & improved anti-poaching efforts

In a close collaboration with the Southern African Wildlife College, CAKE’s engineers have developed the Electric Bush Bike series, allowing rangers to approach poachers silently without being detected and making way for more efficient anti-poaching patrolling in the region. In close collaboration with the rangers, the platform will be tuned and optimized continuously, for the purpose of creating the best vehicle possible for anti-poaching.

Bikes by rangers, for rangers.

about Kalk AP

made for effective anti-poaching in the wild
The Kalk AP has been engineered for wildlife conservation areas, a force to be reckoned with along the trails of the African bush. 18" off-road tires, a rear carrier to attach arms and medical equipment, suspension modified for low maintenance – the anti-poaching bike is built for efficient wildlife protection, with premium components for low maintenance and long-lasting use.

More about the Kalk AP

The Kalk AP derives from the powerful torque, unique power-to-weight ratio and off-road capabilities of the Kalk series. Unique to its kind, the Kalk AP has been developed to run on solar power, with sustainable plastic fenders and a drivetrain software modified for exceptional torque, enabling maximum efficiency with minimum disturbance.

Built for off-road patrolling
The African bush is a rugged landscape, demanding vessels with resilient capabilities. In addition to its knobby 18″ off-road tires, the Kalk AP’s suspension is modified with a progressive rear shock and an overall low maintenance setup. All to make way for less servicing and more successful anti-poaching work in the wild.

The bike is chargeable through a solar-powered station and solar cells provided by Goal Zero, to make way for off-the-grid electricity access and more regular patrolling without using fuel, an expensive and scarce resource in the region.

Continuous in-field updates
In our news page we will regularly update with the latest progress from the field, learnings, changes, successes, setbacks and more from the ongoing anti-poaching project. Simultaneously, we will adapt and fine tune our work together with the SAWC, to bring the most out of our project for the coming weeks, months and years. Make sure to follow our news page to receive the latest.
