While automakers debate who will bring solid-state batteries to the mass market first, Finland has decided to move faster. Donut Lab says its new battery is no longer a lab-bound prototype but a verified technology already integrated into production machines, slated to hit the road in the coming months. The first application will appear at Verge Motorcycles, with the rollout expected in the first quarter of 2026.

The flagship will be the Verge TS Pro, an electric superbike already open for orders in Europe. The headline figure is an energy density of 400 Wh/kg—nearly double that of conventional lithium‑ion packs with liquid electrolyte. From there come the range claims: up to 600 km in city use and about 315 km on the highway at a steady 90 km/h.

Performance targets are equally bold. Base versions are rated at 102 kW (138 hp) and 1,000 Nm, with 0–100 km/h in 3.5 seconds and a top speed of up to 200 km/h. The top spec claims 150 kW (204 hp) and 1,200 Nm, trimming the 0–100 km/h sprint to 2.5 seconds. Fast charging is emphasized: under 10 minutes without the usual pause at 80%, plus an estimate of 60 km of range per minute plugged in. There’s also a particularly ambitious durability promise—over 100,000 cycles with minimal degradation. If these figures hold up on real roads, they would reset expectations for electric two-wheelers.

The price matches the pitch: around €40,389 for the solid-state version, a €3,000 premium over the standard-battery model with up to 350 km of range. Given the claimed leap in density, speed of charging, and projected lifespan, that surcharge looks measured; the true test will be how closely the production bikes mirror these numbers outside the spec sheet.
