Finnish “solid-state” (Donut Lab) + Verge motorcycle + Donut Motor
Last updated: 15 Jan 2026
Scope: What Donut Lab and Verge Motorcycles (Finland) are claiming at CES 2026, what is publicly specified, and what is still unverified.
1) Who/what
- Donut Lab (Finland): EV tech company (best known publicly for “Donut Motor” in-wheel/hubless motor concepts) now announcing an “all-solid-state” battery (“Donut Battery”). (Donut Lab)
- Verge Motorcycles (Finland): Electric motorcycle OEM claiming it is now offering production motorcycles with solid-state battery technology (powered by Donut Lab). (Verge Motorcycles)
2) Solid-state battery: what is being claimed (company statements)
Donut Lab claims (their CES 2026 announcement):
- 400 Wh/kg gravimetric energy density. (Donut Lab)
- Full charge in 5 minutes (explicitly “not limited to 80%”). (Donut Lab)
- Extreme-temperature performance claims:
- At –30°C: >99% capacity retained
- At >100°C: >99% capacity retained, with “no signs of ignition or degradation” (Donut Lab)
- Deployment claim: batteries “placed immediately on the road” in Verge’s lineup, with “real-world use … in Q1.” (Donut Lab)
Verge claims (their announcement + product page language):
- “Customer-ready” solid-state motorcycles with ~10-minute charging and up to 370 miles (~600 km) range (headline claim). (Verge Motorcycles)
3) Verge TS Pro: what is publicly specified (published specs/marketing)
From Verge’s TS Pro page/spec section:
- Battery pack options: 20.2 kWh (up to 350 km) or 33.3 kWh (up to 600 km) and described as “solid-state.” (Verge Motorcycles)
- DC fast charge: “Add up to 300 km in under 10 minutes,” using up to 200 kW (and the smaller pack up to 100 kW). (Verge Motorcycles)
- Power / torque: 102 kW; 1,000 Nm; 0–100 km/h 3.5 s; top speed 200 km/h. (Verge Motorcycles)
- Weight: 235 kg (published on the same page). (Verge Motorcycles)
Third-party commentary (still largely based on claims, not teardown validation):
- MotorTrend highlights Verge’s position that the solid-state tech is cheaper to produce and sold at the same price as earlier conventional packs (as stated/claimed in coverage). (MotorTrend)
4) Electric motor: “Donut Motor” and the Verge hubless rear wheel
Verge TS Pro drivetrain claim (published by Verge):
- A patented hubless rear-wheel motor delivering 1,000 Nm directly to the road (chainless). (Verge Motorcycles)
Donut Lab broader motor-family claim (media coverage, CES 2025/2026 context):
- For automotive-spec in-wheel motors, Top Gear reports Donut Lab claims 845 bhp and 3,172 lb-ft at the rotor (Top Gear explicitly cautions torque interpretation), and reports motor weight of 40 kg. (Top Gear)
5) What is not yet verified publicly (key unknowns)
These items determine whether this is truly “all-solid-state” at scale versus marketing shorthand:
- Cell chemistry + electrolyte type: sulfide / oxide / polymer; lithium-metal vs silicon-rich anode; need for stack pressure, etc. (not disclosed in the public materials above). (Donut Lab)
- Independent test data: cycle-life curves, capacity fade, fast-charge repeatability, cold-charge limits, abuse testing by accredited labs (none published in the sources above). (Donut Lab)
- Production evidence: yield, scrap rate, factory throughput, supplier ecosystem, warranty terms for the “solid-state” pack (not publicly detailed in the sources above). (Donut Lab)
