Sur-Ron Storm Bee – full-size electric motorcycle

Sur-Ron Storm Bee is a full-size electric motorcycle created for those expecting significantly higher performance than that offered by lightweight designs like the Light Bee. The Storm Bee combines a powerful central drive, a large battery, high-end suspension, and an aluminum frame designed for demanding off-road riding.

Depending on the version, the Storm Bee can be intended for off-road/enduro riding, or available as an L3e model with road homologation. The Polish specification for the Storm Bee R version indicates a maximum power of 22.5 kW, a speed of up to 110 km/h, and a range of up to 100 km at 50 km/h.

Powerful 22.5 kW motor

The Storm Bee utilizes a central, brushless electric motor working with an advanced FOC controller. The maximum system power is 22.5 kW, and the maximum torque reaches 520 Nm.

These parameters ensure very strong acceleration and a large amount of torque available during off-road riding. The drivetrain has been designed to provide appropriate control for both technical enduro riding and faster sections.

90 V / 48 Ah battery

The motorcycle is equipped with a removable lithium-ion battery with a voltage of 90 V and a capacity of 48 Ah, which corresponds to approximately 4320 Wh of energy.

The battery is removable, allowing it to be charged outside the motorcycle. The declared full charging time is approximately 4 hours.

Speed up to 110 km/h

The Sur-Ron Storm Bee reaches a maximum speed of approximately 110 km/h. In the road-legal L3e version, power is limited according to homologation requirements, while the E and F versions are intended for off-road use.

The declared range is approximately 100 km at a speed of 50 km/h. The actual result depends on factors including rider weight, temperature, road surface, terrain, and riding style.

Four riding modes

The Storm Bee offers an extensive system for selecting drive characteristics:

• Eco – calmer characteristics and reduced energy consumption,

• Rain – a setting intended for riding in low-traction conditions,

• Sport – more dynamic drivetrain response,

• Turbo – maximum available dynamics.

Depending on the version, there are also ASR systems responsible for traction control and BERS, a system for energy recovery during braking. ABS is also available in select versions.

Advanced suspension

The Storm Bee features suspension designed for off-road riding.

The front uses a suspension fork with a travel of approximately 290 mm, while the rear suspension provides approximately 290 mm of rear-wheel travel. The front system features adjustment, allowing the characteristics to be adapted to riding conditions and rider preferences.

The long suspension travel helps in overcoming bumps, rocks, roots, ruts, and steep sections of off-road trails.

21" and 18" wheels

In off-road configurations, the Storm Bee uses large spoked wheels:

• front – 21",

• rear – 18".

Depending on the version, off-road tires adapted to the motorcycle's character are used. This solution ensures proper stability and makes it easier to overcome demanding off-road obstacles.

Strong aluminum frame

The Storm Bee uses a high-strength frame made of forged aluminum alloy. The structure was designed to maintain adequate rigidity while minimizing weight.

The wheelbase is approximately 1430 mm, which allows for a combination of stability at higher speeds and appropriate maneuverability during off-road riding.

Hydraulic suspension and full-size design

The Storm Bee is a significantly larger motorcycle than the Light Bee X. Depending on the version, the vehicle's weight with the battery is approximately 127–136 kg, and the seat height is approximately 940–975 mm.

The ground clearance reaches approximately 310–335 mm, allowing the motorcycle to effectively overcome obstacles and bumps encountered during off-road riding.

Electronic systems

The Storm Bee is equipped with an extensive set of riding assistance systems. Depending on the version, these include:

• ASR – traction control,

• BERS – energy recovery during braking,

• ABS – available in specific versions,

• several riding modes,

• reverse gear,

• digital LCD display.

This allows the rider to adjust the motorcycle's behavior to the type of surface and current conditions.

Technical specifications

Parameters may vary depending on the Storm Bee version and the sales market.

Available Storm Bee versions

Storm Bee R L3e – a version prepared for road use and equipped with L3e homologation. In this configuration, power is limited according to homologation requirements.

Storm Bee E – an enduro version intended primarily for off-road riding.

Storm Bee F – a variant focused on off-road riding, without road homologation.

Summary

Sur-Ron Storm Bee is a full-size electric motorcycle designed for demanding off-road riding. The combination of 22.5 kW of power, 520 Nm of torque, a 90 V 48 Ah battery, large 21"/18" wheels, and extensive suspension allows it to far exceed the capabilities of lightweight electric off-road motorcycles.

Thanks to several riding modes, traction control, energy recovery, and the availability of different construction versions, the Storm Bee can be configured as both an L3e road motorcycle and as a machine intended solely for enduro and off-road use.

Before purchasing, it is worth precisely identifying the version of the vehicle, as the Storm Bee R, E, and F differ in terms of, among other things, homologation, weight, dimensions, suspension, and equipment.
