Sur-Ron
Ultra Bee

The grown-up Sur-Ron. Better stock parts than the Light Bee but owners still chase Sirris suspension and EBMX power, so takeoffs flow steadily.

Drive system: Mid-mounted PMSM: 12.5kW peak (2023-2024); V2/HP hairpin-wound motor 18kW sustained, 21kW peak (2025-2026)
Stock battery: 74V 55Ah (2023-2024); 74V 60Ah (2025-2026 V2/HP)

up to $244

Top trade-in value of the 11 stock parts we track, graded like-new. Heads up: takeoff supply on scene bikes is deep, so credit runs lean — clean parts often do better sold on the used board.

The rest covers shipping, fees, hold time, and no-sale risk. Good, fair, and rough grades pay 80%, 60%, and 35% of the listed value.
