Understanding the Throttle and Its Function
The throttle is a crucial component responsible for regulating the speed and power of the electric motor.
Typically located on the right handlebar, it can be in the form of a twist grip or a thumb lever. By twisting or pressing the throttle, a signal is sent to the controller, which then adjusts the current supplied to the motor.
The more the throttle is twisted or pressed, the greater the power and speed generated.
How to Fix the Super73 Throttle Not Working Issue?
#1. Check the battery charge level
One possible reason why the Super73 throttle is not working is that the battery charge level is too low.
A low battery can affect the performance of the electric bike, including the throttle. You can charge the battery fully and then try the throttle again.
#2. Verify the mode setting
Another possible reason why the Super73 throttle is not working is that the mode setting on the app or monitor is not correct.
Modes 1 and 3 are designed for pedal assist only and will disable the throttle. You need to set the mode to 2 or 4, which activates the throttle.
#3. Inspect the brake switches
A third possible reason why the Super73 throttle is not working is that the brake switches on both brake levers are stuck or activated, as this can cut off power to the motor and render the throttle non-responsive.
You can try to release the brake switches or adjust them if they are faulty.
#4. Examine the main harness connections
A fourth possible reason why the Super73 throttle is not working is that the main harness connections between the battery, controller, and motor are loose or corroded.
You can unplug and replug the connectors or clean them if they are dirty.
#5. Inspect the throttle connection
A fifth possible reason why the Super73 throttle is not working is that the throttle connection to the controller is damaged or loose. You can check the wires and pins for any signs of wear or tear or replace the throttle if it is defective.
#6. Test the throttle unit
A sixth possible reason why the Super73 throttle is not working is that the throttle unit is malfunctioning. You can test the throttle unit with a multimeter and measure its resistance value.
A normal throttle should have a resistance value between 0 and 5 kΩ, depending on how much it is twisted or pressed. If the resistance value is out of range or fluctuates erratically, the throttle may be damaged and need to be replaced.
#7. Test the controller unit
A seventh possible reason why the Super73 throttle is not working is that the controller unit is malfunctioning. You can test the controller unit with a multimeter and measure its output voltage to the motor.
A normal controller should have an output voltage that varies according to the throttle input, from 0 to 48 V. If the output voltage is constant or zero, regardless of the throttle input, the controller may malfunction and need to be replaced.
#8. Reset the controller
An eighth possible reason why the Super73 throttle is not working is that there are errors or glitches in the controller’s software that may affect the throttle functionality.
You can reset the controller by disconnecting the battery for a few minutes and then reconnecting it. This may help to clear any errors or glitches in the controller’s software.
#9. Contact Super73 customer support or visit a dealer
A ninth possible reason why the Super73 throttle is not working is that there is something else wrong with your electric bike that I cannot diagnose or fix.
You can contact Super73 customer support or visit a dealer for further assistance if none of the above steps work. They may be able to diagnose and fix the problem for you or provide you with a replacement part if needed.
Why Super73 Throttle Not Working?
#1. Low battery charge level
One of the most common reasons why the Super73 throttle is not working is that the battery charge level is too low.
The battery is the main source of power for the electric bike, and if it is not sufficiently charged, it can affect the performance of the bike, including the throttle.
The throttle is a device that controls the speed and acceleration of the bike by sending signals to the motor. If the battery is low, the signals may be weak or interrupted, and the motor may not respond to the throttle input.
To fix this issue, you can charge the battery fully and then try the throttle again. You can check the battery charge level on the app or monitor.
#2. Incorrect mode setting
Another common reason why the Super73 throttle is not working is that the mode setting on the app or monitor is not correct.
The Super73 electric bike has four modes that can be selected by the user: mode 1, mode 2, mode 3, and mode 4.
Mode 1 and mode 3 are designed for pedal assist only, which means that the motor will only provide power when the user pedals.
Mode 2 and mode 4 are designed for throttle activation, which means that the motor will provide power when the user twists or presses the throttle.
If you have selected mode 1 or mode 3, the throttle will be disabled and you will not be able to use it. To fix this issue, you can set the mode to mode 2 or mode 4, which activates the throttle.
#3. Stuck or activated brake switches
A third common reason why the Super73 throttle is not working is that the brake switches on both brake levers are stuck or activated.
The brake switches are devices that detect when the user applies the brakes and send signals to the controller to cut off power to the motor.
This is a safety feature that prevents the bike from accelerating when braking.
However, if the brake switches are stuck or activated, even when the user is not braking, they can cut off power to the motor and render the throttle non-responsive.
To fix this issue, you can try to release the brake switches or adjust them if they are faulty.
#4. Loose or corroded main harness connections
A fourth common reason why the Super73 throttle is not working is that the main harness connections between the battery, controller, and motor are loose or corroded.
The main harness is a bundle of wires that connects the battery, controller, and motor and allows them to communicate and transfer power.
If the main harness connections are loose or corroded, they can cause poor or intermittent contact, which can affect the throttle functionality.
To fix this issue, you can unplug and replug the connectors or clean them if they are dirty.
#5. Damaged or loose throttle connection
A fifth common reason why the Super73 throttle is not working is that the throttle connection to the controller is damaged or loose.
The throttle connection is a wire that connects the throttle unit to the controller and allows the throttle to send signals to the controller.
If the throttle connection is damaged or loose, it can cause faulty or no signal transmission, which can affect the throttle functionality.
To fix this issue, you can check the wires and pins for any signs of wear or tear or replace the throttle if it is defective.
#6. Malfunctioning throttle unit
A sixth common reason why the Super73 throttle is not working is that the throttle unit is malfunctioning. The throttle unit is a device that controls the speed and acceleration of the bike by sending signals to the controller.
The signals vary according to how much the user twists or presses the throttle. The throttle unit has a resistance value that changes with the throttle input.
A normal throttle should have a resistance value between 0 and 5 kΩ, depending on how much it is twisted or pressed.
If the resistance value is out of range or fluctuates erratically, the throttle may be damaged and need to be replaced. To fix this issue, you can test the throttle unit with a multimeter and measure its resistance value.
#7. Malfunctioning controller unit
A seventh common reason why the Super73 throttle is not working is that the controller unit is malfunctioning. The controller unit is a device that regulates the power output to the motor according to the signals from the throttle and other sensors.
The controller unit has an output voltage that varies according to the throttle input, from 0 to 48 V. If the output voltage is constant or zero, regardless of the throttle input, the controller may malfunction and need to be replaced.
To fix this issue, you can test the controller unit with a multimeter and measure its output voltage to the motor.
I hope this helps you to troubleshoot your Super73 throttle issue. If you need more assistance, you can contact Super73 customer support or visit a dealer.
