The mandatory national standard Technical Specifications for Safety of Electric Bicycles, revised by the Ministry of Industry and Information Technology (MIIT) and four other departments, will come into effect on September 1, 2025. The updated standard stipulates that plastic content in e-bikes must not exceed 5.5% of total vehicle mass, with a maximum weight limit of 55 kg for lithium battery models and 63 kg for lead-acid battery models.
This dual focus on "plastic restriction" and "weight control" creates significant opportunities for magnesium applications in the electric two-wheeler sector. Magnesium alloys, with ultra-lightweight properties, electromagnetic shielding, and vibration damping, are already being adopted by industry leaders like Aima, Yadea, and Niu Technologies for components such as wheels and frames, achieving weight reduction, extended battery range and improved shock absorption.
The annual production of electric two wheelers in China exceeds 50 million units, which is conservatively estimated to bring an annual increase of over 100,000 tonnes to magnesium applications, providing new development opportunities for the entire magnesium industry and injecting new vitality into the magnesium industry chain.
