Exclusive $ \pi^0 $ electroproduction is analyzed within the handbag approach based on Generalized Parton Distribution (GPDs) factorization. We consider the leading-twist contribution together with the transversity effects. It is shown that the transversity GPDs $ \pi^0 $ and $ \pi^0 $ are essential in the description of the $ \pi^0 $ cross section. Predictions for the future Electron-Ion Collider of China (EicC) energy range are provided. It is found that transversity dominance $ \pi^0 $ , observed at low energies, is valid up to the EicC energy range.
