In Joel Esteban's debut season in the European Talent Cup, he managed to step onto the podium in his first race. His impressive performance caught the attention of the Aspar Junior Team, which signed him for the 2021 season in the same category. The young Catalan rider secured three consecutive victories, accompanied by four additional podiums. However, due to medical reasons, he was unable to contend for the championship. In 2023, he moved up to the Finetwork FIM JuniorGP™, adding four more podiums to his résumé, including two victories, a pole position, and a Top 4 finish in the overall standings. For 2024, Esteban will make the leap to the Moto3™ World Championship with the Aspar Team.
