UA researchers develop a more comfortable and efficient bicycle system

A group of researchers and professors from the Centre for Mechanical Technology and Automation (TEMA) and the Department of Mechanical Engineering at the University of Aveiro (UA) has developed a rear bicycle hub system that enhances cyclist performance without compromising safety, providing a smoother gear‑shifting experience.

The invention, developed by António Bastos, António Ramos and Francisco Vieira, focuses on the internal mechanism of the hub, which enables twice the number of engagement points compared with traditional hubs available on the market. This increase in engagement points results in a faster and more efficient response during gear shifting, as felt at the pedal. Cyclists can expect improved performance, particularly in situations that require rapid changes in speed and power.

The system was designed to be compatible with any type of bicycle, regardless of cycling discipline or energy system (electric, assisted or manual).

This new technology not only increases cyclist performance but also prioritises user comfort. The system was engineered to absorb vibrations generated during freewheel movement, minimising discomfort caused by noise. This aspect is particularly important for cyclists who cover long distances or face challenging terrain, ensuring a more pleasant and less fatiguing riding experience.

The researchers emphasise that this patented technology has the potential to make a significant impact on the cycling market by offering an advanced solution suitable for both professional cyclists and enthusiasts.

This project was funded under the Mobilising Agenda for Business Innovation in the Two‑Wheeler Sector (AM2R Agenda).

With the innovation now patented, the research team will move forward with prototype production and, with the support of the University of Aveiro’s technology transfer office, UACOOPERA, will initiate contact with project partners to promote its commercialisation.
