In 2021, TBS and GoTo Group formed a collaborative venture known as PT Energi Kreasi Bersama, operating under the brand name "Electrum."

Within the electric vehicle sector, TBS aims to establish a comprehensive electric motorcycle ecosystem, contributing to the overall transformation of the value chain to bolster Indonesia’s national self-sufficiency in the electric motorcycle industry and downstream natural resources.

Electrum is poised to create a unified electric vehicle ecosystem, spanning from initial production to end-user services. This encompasses the manufacturing of electric motorcycles, advancements in battery manufacturing technology, the establishment of battery swap infrastructure, the development of charging stations, and the provision of financing solutions.
