The Surron Light Bee 2 brings motorcycle-level performance into a lightweight electric off-road platform. Surron lists a maximum speed of 90 km/h, or approximately 55.9 mph, together with 24 kW of maximum power and acceleration from 0 to 50 km/h in 1.8 seconds.
Those figures establish the performance potential of the Light Bee 2 X. They do not mean that every bike, rider and route will produce exactly the same speed.
Battery state of charge, temperature, rider load, wind, terrain, tires, software, gearing and regional configuration can all affect the speed available in real riding. The useful question is therefore not simply, “Can the Light Bee 2 reach 90 km/h?” It is what allows the complete system to approach that figure—and what may prevent it from doing so.

What the Official 90 km/h Figure Means
Surron currently lists 90 km/h as the maximum speed of the Light Bee 2. This is a manufacturer reference for the specified production configuration, not a guarantee that the dashboard will show the same number in every situation.
Maximum speed is reached when the power available at the wheel is sufficient to overcome all opposing loads. These include:
- Aerodynamic drag
- Tire rolling resistance
- Drivetrain losses
- Elevation and surface resistance
- Software and motor-speed limits
- Battery voltage drop under load
As speed rises, aerodynamic drag becomes increasingly important. The power required to gain the next few kilometers per hour can be much greater than the power required at lower speed.
This is why adding power does not produce a simple one-to-one increase in maximum speed.
What 24 kW Tells Us—and What It Does Not
The Light Bee 2 is listed with 24 kW of maximum power. Converted directly, 24 kW is approximately 32.2 mechanical horsepower.
That conversion is useful for comparison, but it does not mean the motorcycle delivers 32.2 hp continuously in every riding mode.
Maximum power normally describes the highest output available under defined electrical, thermal and software conditions. Continuous output can be lower because the motor, controller and battery must remain within their operating limits.
Actual power at a given moment depends on:
- Riding mode and controller calibration
- Battery voltage and state of charge
- Battery and BMS current limits
- Motor speed
- Motor and controller temperature
- Available traction
- Software protection strategies
Peak power helps explain the Light Bee 2’s acceleration and high-speed capability. It should not be treated as a complete description of how the bike performs throughout an entire ride.
Acceleration and Top Speed Are Different Measurements
The Light Bee 2’s published 0–50 km/h time of 1.8 seconds demonstrates how quickly the powertrain can accelerate its 65 kg platform.
Surron also lists 0–80 km/h in 3.43 seconds. The additional time required between 50 and 80 km/h reflects the increasing resistance the motorcycle must overcome as speed rises.
Acceleration is strongly influenced by torque, vehicle mass and traction. Maximum speed depends more heavily on power at higher motor speed, gearing, aerodynamics and electronic limits.
A motorcycle can therefore have very strong low-speed acceleration without having an unlimited maximum speed. Likewise, a gearing change that supports a higher theoretical speed can reduce acceleration or place the motor outside its most efficient operating range.
The Light Bee 2’s published 410 N·m figure is maximum torque at the wheel, after the drivetrain’s reduction ratio. It should not be interpreted as motor-shaft torque or compared directly with figures measured at a different point in another powertrain.
Eight Factors That Change Real-World Light Bee 2 Speed
1. Regional Version and Software Configuration
Road-legal and off-road versions may use different equipment, calibration or speed restrictions. Riding modes can also change throttle response and the amount of power available.
Always identify the exact model and market version before comparing speed figures.
2. Battery State of Charge
Battery voltage is normally higher near a full state of charge and declines as energy is used. Under hard acceleration, voltage can also fall temporarily because of internal resistance.
The bike may feel strongest earlier in the ride. Later, the controller or BMS may reduce output to protect the battery and maintain a safe reserve.
3. Battery Temperature
Cold temperatures can reduce available battery performance and increase voltage sag. High temperatures can cause the BMS, controller or motor to apply thermal protection.
A speed result recorded in mild conditions should not automatically be expected in very cold or hot weather.
4. Rider Weight and Riding Position
Additional mass affects acceleration and climbing more directly than steady speed on level ground. At higher speed, however, the rider’s position and frontal area become increasingly important.
An upright position, loose clothing or a strong headwind can raise aerodynamic drag. A lighter rider may accelerate more quickly, but aerodynamics can matter more than weight near maximum speed.
5. Terrain and Gradient
Uphill riding requires the motor to lift the combined mass of the bike and rider. Loose soil, sand, mud and grass can also increase resistance or reduce traction.
A downhill dashboard reading is not a useful measure of the bike’s repeatable, power-limited top speed.
6. Tires and Tire Pressure
Tire size, tread pattern, pressure and condition affect both traction and rolling resistance. Aggressive off-road tires can provide better grip on loose terrain while consuming more energy on a hard surface.
Changing the rolling diameter can also affect speedometer accuracy and the relationship between motor speed and road speed.
7. Gearing and Drivetrain Condition
Gearing influences the balance between acceleration, climbing ability and theoretical maximum speed. A taller ratio does not guarantee that the motor has enough power to reach the resulting theoretical speed.
Chain tension, alignment, lubrication and bearing condition can also add mechanical loss.
8. Wind and Speed Measurement
Headwind can materially reduce high-speed performance, while tailwind may increase it. Dashboard readings can also differ from GPS measurements because of wheel-size calibration and normal speedometer tolerance.
For meaningful comparisons, use the same route, rider, tire setup, state of charge and measurement method.
Why Maximum Speed Reduces Range
The Light Bee 2’s maximum-speed capability and its range figures describe different operating conditions.
Surron lists up to 160 km at 25 km/h and 108 km at 40 km/h. Riding near maximum speed requires substantially more power than either controlled range condition.
Higher speed increases aerodynamic drag, while repeated acceleration adds further energy demand. The battery therefore supplies more watt-hours per kilometer, reducing the distance available from the same stored energy.
Riders planning longer routes should not calculate range from the 90 km/h figure. Start with a conservative energy-consumption baseline taken from your own riding.

Will a Larger Battery Make the Light Bee 2 Faster?
Not necessarily.
A higher-capacity battery primarily stores more energy. When voltage and the rest of the power system remain unchanged, the most direct benefit is potentially longer riding time.
A battery may help the motorcycle maintain performance more consistently if it can supply the required current with less voltage sag. That is different from increasing the software-controlled or motor-speed-limited maximum speed.
Top speed is determined by the complete system:
- Battery voltage range
- Battery and BMS discharge capability
- Controller voltage and current limits
- Motor speed and thermal limits
- Controller software
- Gearing
- Wheel and tire diameter
- Available traction
- Wiring and connector ratings
Installing a higher-voltage battery without confirming every connected component can damage the motorcycle or create a serious safety risk.
An existing TRB POWER Light Bee battery should not be assumed to be compatible with the Light Bee 2 from a nominal voltage label alone. Fitment, full-charge voltage, controller limits, BMS communication, connectors, charger and software behavior must all be verified.
See our Light Bee 2 Battery Upgrade Planning Guide for the complete compatibility checklist.
What a Well-Planned Performance Upgrade Should Improve
A useful performance build is not defined by one short dashboard run. It should deliver repeatable output without exceeding the limits of the battery, controller, motor, wiring or chassis.
Before planning a Light Bee 2 performance project, define:
- The exact bike and regional version
- The target acceleration and maximum speed
- The required riding range
- Rider weight and normal terrain
- Tire and gearing configuration
- Battery voltage and current requirements
- Controller and motor limits
- Cooling and thermal-management requirements
- Brake, suspension and chassis requirements
- Legal restrictions in the intended riding location
More power and speed also increase the demands placed on tires, brakes, suspension, protective equipment and rider skill.
The Real Meaning of the Light Bee 2 Top-Speed Claim
The official 90 km/h figure matters because it shows how far the lightweight Light Bee platform has advanced.
At 65 kg, the Light Bee 2 combines low mass with 24 kW of maximum power, strong wheel torque and acceleration that extends beyond trail-bike speeds. Its performance comes from the coordination of the battery, controller, motor, drivetrain, software and chassis.
The important lesson is that maximum speed is a system result—not a battery specification, motor label or controller setting viewed in isolation.
A serious upgrade should begin with the rider’s goal and then define what every part of the system must support safely and repeatedly.
