But the company has started assessing dealers in key European markets, two of the sources said, after the company's president last month said sales in Europe were not meeting expectations.
One person said Nio had found that Europe had its "peculiarities", without elaborating, and that the company was planning to expand into more European countries.
Its Firefly project, however, is evaluating its channel model for Europe, including direct sales, agency or dealers.
Nio, which ranks ninth by sales volume among manufacturers of electric and hybrid cars in China, does not break down its sales in Europe.
Nio does not use dealers in China but instead relies on a direct sales model similar to one pioneered by Tesla (TSLA.O).
