CIXI explains chainless technology

The LEVA-EU member describes how its cutting-edge technology adds freedom to active mobility. By eliminating the need for mechanical transmission, it optimizes convenient riding experiences for a range of vehicles with powerful, intuitive pedalling and easier maintenance.

The French brand explains that its chainless technology is a great solution for one, two, three and four wheeled vehicles because it eliminates grease, rust and the need for constant maintenance. It states that it replaces the need for mechanical transmission by incorporating “the benefits of pedalling into a scalable block to build architectures beyond the electric bike, keeping the ease, intuitiveness, and benefits of human pedaling. Whatever the style, the load, the speed, the wheels: one, two, three, four..”

The significance in pedaling haptics for optimising user experiences

Haptics refers to any type of interaction that uses forces or movements for user communication – such as tactile feedback when using smartphone functions. CIXI states that by removing the need for a chain, its PERS system haptics imitate the function of a chain, enabling riders with a new control level as they move actively through pedalling.

CIXI emphasises that the concept of haptics and force feedback shouldn’t be overlooked, as it makes users feel comfortable and connected to their vehicle.

Its PERS pedalling system stands for Pedalling Energy Recovery System, a device that translates human pedalling energy into electricity for movement. It enhances the pedalling experience by being:

• Easy to use – requiring no gear shifting, as the system intuitively and continuously adapts to the ratio between the rider’s cadence and wheel speed. It adapts to the rider’s style and intention, bringing a smooth, uninterrupted flow of power.
• Responsive – it brings the exact torque at the exact millisecond required, intelligently translating the rider’s intention to the vehicle. It contains up to 185 Newton-meters of resistive torque, so there will be no lag when pedalling.
• Reliable and durable – it removes the need for exposed and vulnerable mechanical parts, bringing cost-effectiveness above marginal gains in efficiency. CIXI says this brings long lifecycles for vehicles (after testing PERS for 50,000 km). Chainless technology represents fewer components, minimised maintenance with no greasy parts, no broken chains or belts.
• Effective and scalable – in real time, it translates human energy into electricity, using this energy to give users full control over their vehicle. Its high integration, flexibility, and simplicity make it possible to pedal in many other architectures focused on the rider’s needs beyond the bike.
• Evolutive – via its integrated IoT box it is connected to a cloud, which enables over-the-air updates, smart features, and safety improvements, allowing it to get better over time.

CIXI’s PERS chainless pedaling system is a “pedal-by-wire” system adopting a “serial hybrid” architecture:
