Learn Surron Wheelie Control In 5 Minutes (for Ultra Bee HP)

⏱️ About a 5 minutes read

SWC (SURRON Wheelie Control) is a rider-assist function that helps manage front wheel lift by monitoring vehicle pitch angle and limiting drive torque when the pitch approaches a rider-defined target.

SWC uses IMU feedback to estimate the motorcycle’s attitude. The system compares the measured pitch angle against the configured wheelie angle, then reduces torque as required to stabilise the front-end lift near the selected limit.

SWC is a torque management assist. It does not balance the motorcycle automatically and does not replace rider skill, rear brake control, or steering correction.

SWC functionality described in this guide applies only to the official SURRON Ultra Bee HP (MY2025) distributed through authorised channels and equipped with compatible firmware.

Official New Zealand Units

Authorised New Zealand Ultra Bee HP units:

• Support the SURRON App
• Allow firmware compatibility updates
• Enable full SWC functionality
• Provide access to GPS monitoring features

SWC performance and system behaviour are dependent on proper firmware integration between the battery, MCU, and control systems.

-----------------------------------

Parallel Imported Units

Parallel imported units may not:

• Support the SURRON App
• Receive compatible firmware updates
• Enable full SWC functionality
• Provide access to GPS monitoring

As a result, SWC features and connected services may be limited or unavailable.

For full SWC capability and GPS integration, official authorised units are required.

SWC is a pitch-based torque control system.

It monitors the motorcycle’s angle during acceleration and reduces power when the front wheel reaches a selected height.

The system uses an onboard IMU (Inertial Measurement Unit) to measure pitch angle. The control unit then compares this measured angle to the rider’s chosen setting.

If the motorcycle approaches the configured limit, the system reduces torque to help prevent excessive lift.

Important:

SWC assists power control.

It does not balance the motorcycle automatically.

It does not replace rider skill.

SWC operates in four stages:

1. The IMU measures the bike’s pitch angle.
2. The rider selects a wheelie angle.
3. The control unit compares real-time angle to the selected value.
4. If the angle approaches the limit, torque is reduced.

When the pitch returns below the threshold, normal power delivery resumes progressively.

This is known as a closed-loop assist system. It responds continuously while active.

SWC is configured through the dashboard.

Default state:

W0 – SWC OFF

Enabled state:

W1 – SWC ON

Activation procedure:

1. Turn ignition ON.
2. Ensure the motorcycle is not in READY state.
3. Press and hold ASR + READY to enter feature settings.
4. Change W0 to W1.
5. Confirm activation via the display indicator.

Once enabled, SWC remains available unless disabled manually or interrupted by protection logic.

SWC provides two working levels.

N1 – 15° to 35°
Designed for lower angle control and progressive learning.

N2 – 35° to 60°
Designed for higher angle wheel lift for experienced riders.

Switch levels by double-clicking READY.

For first-time users, N1 is strongly recommended.

Each level allows a custom angle setting.

To adjust:

1. Long-press READY.
2. The current angle will display steadily.
3. Press READY to increase the angle.
4. Long-press READY again to save.

If no input is made, the system exits automatically and saves.

Begin with a conservative setting such as 20° to 25° before increasing.

If you are new to SWC, follow this progression:

Step 1 – Enable SWC (W1)

Step 2 – Select N1

Step 3 – Set angle between 20° and 25°

Step 4 – Practise in a straight, closed area

Step 5 – Increase angle gradually after consistent control

Increase in small increments. Avoid large angle jumps.

Practice should always be conducted in controlled environments.

SWC depends on proper system conditions.

The system may disable or refuse activation if:

• Battery temperature is outside operating range
• Battery power capability is insufficient
• Protection mode is active
• Reverse speed exceeds 3 km/h

If SWC disengages:

• Reset the motor stop switch, or
• Restart the ignition

This restores the system to default state.

Why will SWC not enable?

Possible causes:

• Battery condition not suitable
• Firmware mismatch
• System not in correct menu state

Why did SWC turn off during use?

Possible causes:

• Reverse speed exceeded limit
• Protection logic triggered
• Electrical system condition not stable

Why does SWC feel inconsistent?

Possible causes:

• Angle setting too aggressive
• Rider weight outside recommended range
• Surface conditions affecting traction

If issues persist, consult your authorised dealer.

• Horn usage should be avoided during SWC operation due to potential signal interference.

• Do not enable the SWC system during off-road riding.

• ASR traction control and brake override may affect SWC behaviour. The system documentation recommends disabling them during SWC use.

• Regenerative braking operates independently of SWC.

Rider weight range:
45 kg to 100 kg

Use environment:
Closed, straight, non-public riding areas only.

SWC does not prevent crashes.
It does not override physics.
It does not replace rider judgement.

The rider remains fully responsible for safe operation at all times.

New Features

The Auto-Hold function helps keep the motorcycle stationary without continuously applying brake pressure.

Function Switch

Auto-Hold is controlled through the system menu:

Z0 – Auto-Hold OFF
Z1 – Auto-Hold ON

--------------------------

Activation

Auto-Hold can be activated when:

• The motorcycle is stationary
• Speed is below 2 km/h

To activate:

1. Rapidly press the brake twice.
2. When activated, the dashboard will display “H”.

--------------------------

Release

Auto-Hold can be released by:

• Rapidly pressing the brake twice again
• Twisting the throttle to move forward
• Turning off the ignition switch

Turning off the ignition will automatically exit Auto-Hold mode.

--------------------------

Important Notes

• It is recommended to turn off Auto-Hold during intense riding such as racing, forest trails, or jumps.

• Auto-Hold cannot be activated if the motorcycle has a system fault or breakdown condition.

• Ignition OFF will always exit Auto-Hold state.

The throttle free play can be adjusted through the feature settings menu.

Adjustment range:

M1 to M5

These levels change the throttle free play clearance.

• M1 – Larger free play
• M3 – Normal setting
• M5 – Very small free play (can feel almost immediate)

As the level increases from M1 to M5, the throttle free play decreases.

Riders should select a setting that provides smooth and controlled throttle response.

Summary

SWC on the Ultra Bee HP (MY2025) is a pitch-based torque management system designed to assist with controlled front wheel lift. The system uses IMU feedback and firmware logic to limit drive torque as the motorcycle approaches a selected wheelie angle.

Correct configuration, progressive setup, and practice in controlled environments are required for safe and consistent operation. SWC is a rider-assist feature. It does not replace rider skill, judgement, or responsibility.

Official Scope and Applicability

This reference guide applies only to the SURRON Ultra Bee HP (MY2025) equipped with compatible firmware and official software integration.

Parallel imported units may not support the SURRON App and may not provide full SWC functionality or GPS feature access.

System behaviour may vary depending on firmware version and overall system condition.

Rider Responsibility

Use SWC only in controlled, non-public riding areas. Always operate within safe conditions and local regulations.

The rider remains fully responsible for safe operation at all times.

This document serves as the primary reference for SWC configuration and operation on the Ultra Bee HP (MY2025).
