Sur Ron Ultra Bee

Sur-Ron Ultra Bee 21kW Electric Dirt Bike

The Sur-Ron Ultra Bee is a mid-size electric dirt bike designed for riders seeking responsive performance, advanced electronic controls and capable off-road suspension. The newer high-performance configuration advertised by the source retailer combines up to 21kW peak motor output with a 74V 60Ah lithium battery.

Positioned between the smaller Light Bee and larger Storm Bee models, the Ultra Bee uses a forged aluminium frame, adjustable suspension and a high-torque electric drivetrain to support riding across demanding off-road terrain.

Key Features

• 21kW peak motor power: Maximum advertised output in Turbo mode on the newer HP configuration.
• 74V 60Ah lithium battery: Removable battery providing 4,440Wh nominal energy capacity.
• Approximately 95km/h top speed: Published unrestricted performance figure.
• High-torque electric drivetrain: Mid-mounted permanent magnet motor with advanced electronic control.
• Adjustable suspension: Approximately 240mm front fork travel and adjustable rear suspension.
• Traction control: Electronic assistance for managing driven-wheel slip.
• Regenerative braking: Adjustable motor-assisted deceleration and energy recovery.
• Multiple riding modes: Selectable power delivery settings and reverse functionality.

21kW Electric Motor Performance

The newer Sur-Ron Ultra Bee HP is equipped with a mid-mounted permanent magnet synchronous motor and an advanced electronic controller.

The published performance configuration offers up to 18kW in Sport mode and 21kW peak output in Turbo mode. These values are maximum output figures, not approved continuous motor ratings.

High-performance versions are advertised with approximately 511Nm of peak rear-wheel torque and acceleration from 0 to 50km/h in around two seconds.

Actual performance depends on riding mode, battery charge, rider weight, terrain and the supplied motorcycle configuration.

74V 60Ah Lithium Battery

The reviewed Ultra Bee configuration uses a 74V 60Ah lithium-ion battery. Multiplying the published voltage and amp-hour capacity gives approximately 4,440Wh, equivalent to 4.44kWh of nominal energy.

The battery supports the motorcycle’s higher-output powertrain and is removable according to the manufacturer’s battery-handling procedure.

Earlier Ultra Bee models use a different 74V 55Ah battery. Confirm that your motorcycle is the newer 60Ah configuration before publishing these specifications.

Electric Riding Range

The source retailer advertises up to approximately 115km of riding range under its stated conditions.

Range is strongly influenced by speed, terrain, rider weight, temperature, acceleration and battery condition. Long periods of high-output riding can substantially reduce achievable distance.

Published range figures should be treated as test-condition estimates rather than guaranteed real-world results.

Charging and Battery Management

Published Ultra Bee HP specifications identify approximately 2.5 hours for charging from 20% to 80% with the appropriate charging equipment.

A full charge may take longer. The time depends on the supplied charger, battery temperature and starting charge level.

The retailer quotes a charging window of approximately 2.5 to 4.5 hours, without clearly establishing a single percentage range for both figures.

Confirm the included charger, electrical plug and charging instructions before publishing a fixed charging-time claim.

Adjustable Off-Road Suspension

The Ultra Bee features an inverted hydraulic front fork and adjustable rear suspension.

Newer high-performance specifications identify approximately 240mm of front fork travel, allowing substantial suspension movement over uneven off-road surfaces.

The rear suspension uses a linked shock system with adjustable settings. Component details and wheel-travel figures can vary between production generations.

Correct suspension setup should follow the manufacturer’s instructions for rider weight and intended use.

Forged Aluminium Motorcycle Frame

Sur-Ron uses a forged aluminium alloy frame to provide strength while controlling overall motorcycle weight.

The newer Ultra Bee HP is published at approximately 88–89kg depending on the reviewed configuration. Earlier Ultra Bee motorcycles have different weight and equipment figures.

The balanced motorcycle layout is intended to support control during off-road acceleration, cornering and suspension movement.

Off-Road Wheels and Tyres

The source retailer advertises a 19-inch front wheel and 18-inch rear wheel combination.

Other Ultra Bee factory configurations use 19-inch front and rear wheels. Wheel, tyre and suspension equipment should therefore be verified against the particular unit being supplied.

Do not assume tyre interchangeability between MX, enduro and road-approved versions without checking the approved dimensions and component compatibility.

Hydraulic Disc Brakes

The Ultra Bee uses front and rear hydraulic disc brakes to provide its primary mechanical stopping force.

Published Ultra Bee specifications include four-piston brake callipers, while exact rotor sizes and brake upgrades vary by model generation.

The braking system should be inspected regularly, particularly after demanding riding conditions.

Traction Control and Regenerative Braking

The Sur-Ron Traction Control System is designed to assist with controlling driven-wheel slip under suitable operating conditions.

Regenerative braking enables the motor to contribute to deceleration and can recover a limited amount of energy.

Both functions supplement correct rider technique and mechanical braking. Their settings should be understood before riding.

Selectable Riding Modes and Reverse

Newer Ultra Bee configurations offer selectable modes including Eco, Daily, Sport and Turbo, with reverse functionality for low-speed manoeuvring.

The exact number and naming of selectable settings may vary by controller generation and regional motorcycle version.

Riders should review the supplied owner’s manual to understand the available modes, restrictions and operating procedures.

Off-Road Use and German Road Requirements

The linked Ultra Bee is described primarily as an off-road electric dirt bike.

Sur-Ron also sells separate L3e road-approved Ultra Bee configurations. Their approved specifications, tyres, lighting, brake equipment and vehicle documents may differ from an unrestricted off-road motorcycle.

German public-road use requires a correctly homologated motorcycle, appropriate registration, insurance and a valid driving licence.

The existence of an Ultra Bee L3e version does not make every Ultra Bee road-legal.

Why Choose the Sur-Ron Ultra Bee?

The newer Ultra Bee combines a powerful electric drivetrain, large lithium battery, lightweight forged aluminium frame and advanced electronic riding controls.

Its adjustable suspension, traction control and regenerative braking make it worth considering for experienced riders looking for a capable electric off-road motorcycle.

Before purchasing from Talaria Bike Sale, confirm the exact Ultra Bee generation, battery and motor specification, included charger, wheel configuration, final selling price and any required vehicle documents.
