NOTE: 
-If you are using an OEM Surron motor you can safely run 15KW of power. We have been running 20KW on an OEM motor with 81V for over 6 months! Running any higher than 15kw you will overheat your motor quickly
 -If you are using a stock Surron battery you can safely run 17KW of power (non bypassed). Anything higher will result in unsafe voltage sage.
-Some OEM display features will be lost, but you will still have all features and functions in the free EBMX tuning app and Eggrider display

Note: Because the Ultra Bee’s stock battery cannot safely handle heavy regen, a thumb throttle for regen is not available with this setup. Regen thumb throttle will be available on the Ultra Bee Race Harness coming soon.

EBMX X-9000 V3 Wheel Lift Assist System

Overview

• Wheel Lift Assist (WLA) is developed in-house by EBMX using real-time IMU data.
• The system can reduce or modulate throttle and apply regenerative braking based on user-defined settings.
• WLA is fully rider-tunable for stunting, launching, or anti-rotation control.
• Important: WLA will never apply throttle on its own. It only reduces throttle and applies braking through logic-based intervention.

Activation & Setup

• Accept the waiver and enable WLA via the EBMX app.
• Double-tap the "On" button on your display to activate WLA (display icon may vary).
• Set the IMU level using Level 0 to activate Auto Horizon calibration.
• Auto Horizon delay is adjustable between 0–30 seconds or can be disabled.

Throttle Off Set Angle

• Defined angle where throttle is cut completely.
• Within 10° of this angle, modulation is aggressive.
• Recommended to set beyond your intended balance point to prevent premature throttle cut-off.
• Default setting for launching is 50°, with increased Modulation Control Percentage for responsiveness.

Start Set Angle

• Angle at which throttle modulation begins (detected by IMU).
• Suggested 10–15° for heavier bikes to allow natural lift before modulation starts.
• Lower values = smoother, earlier modulation. Higher values = more delayed engagement.
• Minimum 30° gap is required between Start Set Angle and Throttle Off Set Angle.

Maximum Set Angle

• Angle where regenerative braking is applied (if Braking Force is enabled).
• Braking strength is determined by settings in Power Modes & Levels.
• Braking effect varies by motor and battery system.
• If Braking Force is disabled, no action occurs at this angle.

Braking Force Percentage

• Defines how much regenerative braking is applied at the Maximum Set Angle.
• Highly effective when used with aftermarket batteries.

Auto Horizon Timer

• When in Level 0, the IMU levels itself automatically based on this delay timer.
• Customizable between 0 and 30 seconds or can be disabled entirely.

Modulation Control Percentage

• Controls how much throttle is reduced when modulation is active.
• Lower percentage = more throttle = more aggressive response.
• Higher percentage = less throttle = smoother response.

Speed

• Optional setting to automatically deactivate WLA when a set speed is exceeded.

Rise Aggression

• Uses IMU angle speed and acceleration to adjust modulation behavior.
• Lower setting = faster rotation.
• Higher setting = slower, more controlled lift.
• Works in balance with Modulation Control % for launch control tuning.
• Recommended: keep at default and tune using Modulation % if you're new.

Timer

• Specifies how long WLA remains in control of the wheel lift event.
