Sur-Ron Storm Bee specs, top speed, range and price
Last updated
The Storm Bee is Sur-Ron's full-size enduro: a proper motocross-sized chassis, a 104V system, and enough top end to keep up with a 250cc four-stroke on fire roads. It is a different class of machine from the Light Bee, and it needs a truck rather than a bike rack.

How fast is it, really?
The Storm Bee is the first Sur-Ron that feels comfortable at highway-adjacent speeds on dirt roads.
Race mode unlocks the full 22.5 kW; Eco keeps it manageable for newer riders.
Real-world range
4.7 kWh sounds huge, but the weight and speed eat it quickly — plan for 30–50 miles depending on pace.
The pack is not removable in the way a Light Bee pack is, so charging means bringing power to the bike.
Verdict
Buy the Storm Bee if you already ride full-size dirt bikes and want an electric that does not feel like a compromise. It is far too much bike for a first-time e-moto rider.
Is it street legal?
Off-road from the factory in North America; road-legal homologation exists in some markets.
