What is the Jarv-E, and how does it differ from the Stark?

Jarv-E is an electric hard enduro bike developed with Graham Jarvis and built in Austria; pre-orders in Europe, first deliveries from spring 2026.

• per the manufacturer: 50 kW, 95 kg, 5.6 kWh battery, quick-swap — about 30 seconds to replace
• the Stark EX: 60 kW (Alpha), 120 kg, 7.2 kWh, battery not quick-swap

Jarvis on the Jarv-E finished 10th at Erzbergrodeo and 11th at Sea to Sky 2026 — the first finish of an electric bike at Sea to Sky.

In short: the Jarv-E is lighter and has a quick battery swap, which matters for long hard enduro; the Stark has a bigger battery and more power, and it's already on sale.
