How To Tune Your Surron Ultra Bee

Best settings for Surron Ultra Bee. How to set up your Surron Ultra Bee.

By now, many of you already own the 2023 Surron Ultra Bee electric dirt bike, so we figured it’s a good time to run through the menu features, explain what they do and help show you the best way to set up and tune your Surron Ultra Bee.

Best Settings for Surron Ultra Bee Video:

Setting Surron Ultra Bee Unit Display:

From the factory the bike is delivered with KILOMETERS selected. If you’d like to switch to miles. Here is what you do. 

With the motorcycle stopped, the key off, and the kick stand fully extended, press and hold the M

button while turning the key to the ON position. Hold the M button for more than 2 seconds to enter the Advanced Feature Setting Mode, then release the M button.

Momentarily pressing the M button will toggle between KILOMETERS, and MILES.

Once you’ve made your selection. Leave the motorcycle powered on and do not move or press any buttons for 10 seconds. This will allow the selected mode to be saved to the Display and return to the normal riding mode.

Setting Surron Ultra Bee Odometer: Total, trip and Maximum Speed. 

With the motorcycle at a complete stop, momentarily pressing the M button will toggle between TOTAL and TRIP distance.

When the Display is set to TRIP Mode, it will indicate the distance travelled and the Maximum Speed since the last reset of the TRIP Odometer. Once the motorcycle begins to move the DISPLAY will switch to the CURRENT SPEED.

To reset the TRIP Odometer and MAXIMUM SPEED, bring the motorcycle to a complete stop leaving the key in the ON position, press and hold the S button for than 2 seconds.

Setting Surron Ultra Bee Transmission Ratio:

This setting is used to calibrate the speed shown on your Display to the speed you’re actually traveling. Typically, you would modify this setting if you change tire or rim sizes. Changing the sprocket tooth count does NOT impact this setting. 

Also, one thing to note, is that this setting does NOT change the actual gear ratio of the motorcycle.

To change the ratio, make sure the key is off, the motorcycle is fully stopped, and the kick stand is fully extended.

Press the “S” Select Button for a minimum of 2 seconds after turning on the key. Release the “S” Button.

Make sure you’re in the Transmission Ratio Advance Feature Setting Mode by looking for the flashing segment on the Display.

Momentarily pressing the S Button will decrease the Transmission Ratio, the M button will increase the Transmission Ratio.

When the Speed indicated on the Display is higher than your actual speed, you will need to reduce the Transmission Ratio until the indicated and actual speeds match. If the Speed indicated on the Display is lower than actual, you will need to increase the Transmission Ratio until the indicated and actual speeds match.

The best way to do this is to cross reference your speed on the display with a gps speed application on your phone to find the accurate setting. 

Small changes in the Transmission Ratio will have a large impact on the Displayed Speed… so you should make changes in .1 increments and recheck the Displayed Speed versus actual speed.

The SURRON Factory default is 1.0

Setting Surron Ultra Bee Time Display

Make sure the key is off, the motorcycle is fully stopped, and the kick stand is fully extended.

Press the “M” Select Button for a minimum of 2 seconds after turning on the key. Release the “M” Button. Momentarily depressing the “M” button will toggle between the HOURS and MINUTES setting.

If you want to adjust the HOUR, ensure the HOUR segments are flashing. This indicates it is ready to be adjusted. Momentarily pressing the “S” button will increase the HOUR indicated by holding down the “S” button will cause the display to increase gradually. Momentarily pressing the “M” button will cause the setting to be stored.

If you want to adjust the MINUTES, ensure the MINUTES segments are flashing. This indicates it’s ready to be adjusted. Momentarily pressing the “S” button will increase the MINUTES indicated by 1. Holding down the “S” button will cause the display to increase gradually.

Momentarily pressing the READY button will toggle between the levels within each FEATURE. 

Brake Energy Regeneration: 

Surron Ultra Bee Brake Regen Setting

This is setting B in your menu

When the bike is moving, the throttle is off, and the brakes ARE applied, the electric motor is switched to a generator and begins to return energy to the battery. Physically, the rider will notice an additional level of braking at the rear wheel when activated versus this feature being disabled.

It should be noted that this feature does not work until the battery has been discharged below 95%.

There are 6 levels labeled between 0 and 5. The factory default is B2, disabled is B0, B1 is the lowest amount of brake energy regeneration, with the regeneration level increasing up to B5 the highest setting.

Coast Energy Regeneration:

Surron Ultra Bee Coast Regen Setting

This is setting E in your menu.

This is what can be closest referred to as engine braking.

When the bike is moving, the throttle is reduced, and the brakes are NOT applied, the electric motor is switched to a generator and it begins to return energy to the battery.

Physically, the rider will notice an additional level of “slowing” or “engine braking” of the motorcycle when activated versus this feature being disabled.

There are 6 levels labeled between 0 and 5. The factory default is E3, disabled is E0, E1 is the lowest amount of regen, with the levels increasing up to highest or strongest setting at E5.

When slowing down, the bike will alternate between brake regen and coast regen based on the throttle position and brake levers being used. 

Pressing either brake lever enables brake regen, releasing both brake levers enables coast regen, as long as the throttle position is less than what is needed to maintain the current speed.

How To Set Traction Control or ASR on Surron Ultra Bee:

Surron Ultra Bee Traction Control Setting

This is setting A in your menu.

During acceleration, the motorcycle compares the RPM of the front wheel to the rear wheel. If the rear wheel RPM is greater than the front wheel the motorcycle, it will reduce the power to the rear wheel to minimize the difference. 

The purpose of this setting is to maximize traction in loose soil conditions.

There are 3 levels labeled between 1 and 3. The factory default is A2, disabled is A1 and A3 is the highest amount of traction control. The setting you select here determines the initial setting the motorcycle enters when ASR is enabled from the left handlebar combination switch.

ASR is enabled and disabled by pressing the ASR switch on the left handlebar switch 3 times, or a single long press, and riders can toggle the intensity level by quickly double pressing the Reverse switch.

How To Set Throttle Sensitivity on Surron Ultra Bee:

Surron Ultra Bee Throttle Sensitivity Setting

This is setting F in your menu.

This feature adjusts how quickly the motorcycle responds to changes in the throttle position. Regardless of the setting selected, full power is always available.

There are 3 levels labeled between 1 and 3. The factory default is F1 and represents the least sensitive response to throttle position changes. F3 represents the most sensitive response to throttle position changes.

How To Set Brake Override or Brake Sensor on Surron Ultra Bee:

Surron Ultra Bee Brake Sensor

This is setting P in your menu.

This feature determines if the electric motor is enabled when either the front or rear brake are engaged.

There are 2 modes labeled 0 and 1. 

P0 allows the motor to be engaged and respond to the throttle while the brakes are engaged.

P1 causes the motor to be disengaged when either brake is applied.

How To Set Tilt Protection on Surron Ultra Bee:

This is setting C in your menu.

This feature determines if the motor is disengaged regardless of the throttle position when the bike senses an extreme tilt angle (such as falling on its side with the rider on the bike still holding the throttle on).

There are 2 modes labeled 0 and 1. 

C0 allows the motor to be engaged and respond to the throttle while the bike is at an extreme tilt angle.

C1 which causes the electric motor to be disengaged when the bike senses an extreme tilt angle (left/right and/or forward/backward). 

How To Enter Reverse Mode on Surron Ultra Bee:

To enter Reverse mode, stop the motorcycle, press and hold the Reverse switch on the left handlebar multi-function control. Then rotate the throttle to adjust the speed.

Surron Ultra Bee Diagnostics:

This is setting T in your menu.

This feature is used for Surron technicians to diagnose potential faults within the power systems of the motorcycle when diagnostic equipment is hooked up to the motorcycle. 

There are 2 modes labeled 0 and 1. The factory default is T0 which causes the diagnostics system to not record system information. T1 enables diagnostic logging.

Setting Charging Power on Surron Ultra Bee:

This is setting U in your menu. 

This feature controls the power level that your Ultra Bee battery charges.

Typically, this setting is changed if you are charging your Ultra Bee at home on a low amperage wall plug or if you’re charging from a generator while on the trail and the circuit breaker trips. 

Selecting a lower power setting will improve your chances of an uninterrupted charge. The charging value selected in the SYSTEM FEATURE SETTING MODE is stored in the battery so charging with the battery removed from the bike will keep your selected charge power.

There are three modes, U1 is 480W, U2 is 750W, and U3 is 1100W. Selecting a lower power mode will increase charging time proportionally. For example, 480W takes 2.5 times longer to reach a full charge than using 1100W.

Exit Feature Setting Mode:

This is setting X in your menu

With the key on you can lift the motorcycle vertical and retract the side stand fully….this will exit the Feature Setting Mode and save all of your changes.

Otherwise, you can let the motorcycle sit for 10 seconds without pressing any buttons and the motorcycle will return to its normal ready to ride state, saving all of your changes.
