How it works

We have been leveraging 3D CAD software for over 30 years to perfect our in-wheel suspension technology. Our innovative work is protected by patents worldwide. From the mechanics of how obstacles are navigated through to precise engineering and assembly processes, there are many factors that contribute to the success of our wheels.

Get in touch

Our patented wheel technology completely replaces conventional suspension systems. Through rigorous design processes, where every stage is questioned or challenged, we have produced a robust design achieving reduced weight, increased load capacity, lower running costs, and reduced vibration.

Our all-in-one wheel technology integrates electric hub motors and suspension, reducing mechanical complexity while addressing common eCargo bike issues, including wheel buckling, flat tires, and cargo damage.

With patents granted in the UK and being rolled out internationally, Zak Mobility remains the only company fully capable of exploiting in-wheel suspension and hub motors in micro mobility.

The wheel

Our in-wheel suspension is made up of three carbon composite springs positioned between the hub motor and the rigid rim. These springs move freely in this space to provide 360 degrees of smooth suspension.

Loading the wheel

When the wheel is loaded with weight, the hub centre creates a non-concentric displacement as it shifts away from the rim. If the load is small, the displacement is small, and if it is large, it is larger.

This reaction of the hub works in all 360 degrees of rotation of the wheel, meaning that the wheel is always reacting to any load in the most efficient way.

Spring rates

Different applications require different levels of suspension. We have developed a range of spring rates for our composite springs to give the correct suspension feel for the wheel. A softer spring will offer greater displacement than a stiffer spring, when subjected to the same load.
