In Ambra Italia's educational project, the transformation of the legendary Ciao Piaggio into an e-bike represents much more than just a technical exercise. For the students of the Technical and Professional Institutes involved, this process is an opportunity to immerse themselves in the world of electric micro-mobility and learn about the key components and innovations that make this transformation possible. Each element of the conversion kit not only provides a practical lesson, but also offers a deep understanding of the technologies used, preparing young technicians to work in the sustainable mobility sector.

The Design and Mechanical Innovation of the Ciao Electric

A key aspect of the transformation of the Ciao Piaggio into an e-bike is the maintenance of its iconic design, which was once a challenge for Ambra Italia and today an interesting topic of study and reflection for students. Respect for the original aesthetic line required a careful selection of materials and technical solutions. The frame, for example, has been adapted without altering its essence, thanks to the use of Ergal and Peraluman components, which guarantee lightness, strength, and flexibility where necessary.

• Rear axle: The choice to use a combination of Ergal and Peraluman for the rear axle is above all a functional decision, which also has its aesthetic advantages. These materials have been selected to reduce weight and improve strength, allowing the strength of the rear axle of the original Ciao to be increased.
• Frame Cradle: The section of the frame cradle has been reinforced with riveted steel side plates, while the battery support plate is made of Peraluman, a light and ductile material, which allows the creation of special profiles and bends.

Through these choices made by Ambra Italia, students learn to understand how mechanical innovation can be integrated with classic design to create a modern and functional product, while respecting the aesthetic appeal of the Ciao.

The Power of Technology: The Electrical Components of Ciao Transformed

The electrical part of the conversion kit is the real technological heart of the project, where students acquire fundamental skills in the management of electrical systems. The motor, battery and control systems represent the innovations that make the Ciao Piaggio an efficient and innovative electric vehicle.

• Brushless Motor: The motor used is a 36V brushless model with 250W of power and a torque of 45Nm, designed to ensure smooth and efficient performance, with a respectable resistance. Students learn how to configure the pedal assist system, which allows the motor to automatically adjust to the chosen level of assistance. This engine, compared to the classic internal combustion engine of the Ciao, guarantees significantly higher efficiency (about 80% compared to 25% for a combustion engine), and this offers students a concrete vision of the benefits of electric mobility.
• Lithium-Ion Battery: The battery, with Samsung cells, thanks to its capacity of 36V and 25Ah (nameplate data at the time of writing the article), offers a range of over 40 km in extra-urban routes. Students learn how to manage and monitor the battery, which is equipped with a Battery Management System (BMS) to ensure the safety and efficiency of the cells. The Bluetooth application allows you to monitor the state of charge even remotely with the battery off.
• Control Unit and Display: The control unit manages the flow of energy between the battery and the motor and is configured to optimise performance according to assistance levels. The digital color display provides essential real-time information, such as speed, battery charge level and assistance mode. Students learn how to interface with these tools and configure parameters for optimal guidance.
• The Motor/Display/Controller system is supplied with a Function Test Report that shows the speeds according to the levels of assistance and the settings entered on the Display.

Safety and Technical Regulations: Preparing Students for the Future

A fundamental aspect of the transformation concerns compliance with safety regulations, in particular the UNI EN 15194:2018 standard, which governs e-bikes. Students have access to laboratory tests conducted by Ambra Italia, which verify the mechanical safety and electromagnetic compatibility of the vehicle. This allows them to understand how design choices determine the results of fatigue tests and Electromagnetic Compatibility, to create vehicles that comply with European regulations.

The electrical system is further protected by glass fuses, which work up to voltages of 250V, and by double insulation on the positive cables. In addition, the battery management system (BMS) offers advanced protection against overloads, ensuring optimal cell balance and long battery life.

Technological Training for the Mobility of the Future

The project to transform the Ciao Piaggio into an e-bike is not just a technical exercise, but an educational experience that prepares students to become protagonists of the future of sustainable mobility. Each component of the transformation kit not only serves a practical function but becomes a learning tool that broadens students' understanding of technological innovation and sustainability.

Ambra Italia, through this project, does not limit itself to providing an educational opportunity: it lays the foundations for an innovative approach to mobility, were tradition and technology blend harmoniously. Training young people on these issues means preparing them for a future in which electric mobility will be at the heart of a global transformation, and this project represents a first step towards that vision.
