Donut Lab's March 31, 2026 deadline for Verge Motorcycles deliveries came and went without independent verification of the company's headline specs. To rebut growing skepticism, Donut Lab launched a PR campaign called 'I Donut Believe' and published three rounds of results from Finland's VTT Technical Research Centre.

Verge Motorcycles claims the TS Pro is now the world's first commercially sold vehicle with a solid-state battery. But VTT never tested energy density or cycle life — the two specs that drew the industry's sharpest skepticism.
