MD: Ride Mode
Pedal Hardness; the lower the percentage the more the pedal leans towards the direction.
ANG: Vertical Angle Adjustment
Front and Back Angle Adjustments. Not to be related with gyroscope calibration.
TLT: Tilt-Back Speed
Speed at which the unit tilts back. Highest value turns off tilt-back.
PWT: PWM Tilt Back Alarm
Tilt back at the PWM value. Highest value turns off PWM tilt back.
ALM: Alarm Speed
Set the speed at which the alarm will sound. Highest value turns off alarm speed.
BRT %: Brightness
Brightness of the Display.
CAL: Calibration
Gyroscope Calibration, Mode 0 is preparing, Mode 1 starts the process, disables the gyro,
please balance the device vertically and hold position. Mode 2, confirms the positions. Mode 3,
complete. Please restart device.
TRM: Transport Mode
IFor transporting the unicycle during shipment, prevents wheel from activating.
UNT: Unit
To switch between KMH and MPH, imperial vs metric.
VtA: Voltage Adjustment
Manually adjusts the voltage of the unicycle to match a realistic number.
STA: Side Tilt Angle (L/R)
Left and right angle cut off. Higher number is ideal for trails and skateparks but may cause the
wheel to spin in place when toppled over.

Adjust the volume of the beeper. Does not impact PWM alarm, only menu alarms.
MxV: Max Charge Voltage
Adjust the maximum limit of voltage.
ANG %: Acceleration Assist
Makes the wheel easier to accelerate by temporarily tilting the pedal forward by a max of 2
degrees.

Alarm will sound when maximum torque is achieved.
ANG TLT: Angle Tilt Re-Centre
Gyroscope recalibration time. 100%= a very long duration 15sec+ VS 0% = stock duration
gyroscope re-centers quickly. When going off berms when you feel tilt back it is due to stock
duration being too quick, try adjusting by increments.
