Why Does My Ride1Up Bike Have An Error Code
E-Bikes get error codes. It’s not rare for them to tell you there’s a problem that needs to be addressed. Knowing the code will tell you what the problem is and how you’re going to fix it.
Complete List of Ride1Up E-Bike Error Codes
Error Code 21
Current abnormality occurs when the controller detects excessive or irregular electrical current. A very general code. This could be from pushing the bike too hard or a faulty wiring issue. The bike is protecting itself from voltage fluctuation.
Firstly, turn the bike off and let it cool down. While it’s cooling down, we recommend checking for any damage. Check the wiring and connections. If they are all in order, continue riding. Just reduce assistance and up the cadence.
Error Code 22
Throttle error caused by irregular signals from the throttle. It could be a faulty throttle, moisture in the connections, or even faulty wiring.
Inspect the throttle and the wiring, connections around it. If you find anything wrong, repair or replace it. If the problem persists, then change the throttle mechanism.
Error Code 23
Motor phase error occurs when the controller cannot correctly energise the motor phases. The most common cause of this is damaged wiring or poor connections.
Checking the controller-to-motor connections is the first step. Have a big focus on the motor cable. Don’t just look for damage to wires, look for broken pins in connectors and loose wiring. If the problem continues, then it might be a new motor or controller.
Error Code 24
Motor hall sensor error occurs when the motor's hall sensor is either sending no signals or irregular signals.
Inspect the motor wiring harness. If wiring is intact, the motor’s internal sensors will need to be inspected by an expert. We don’t recommend opening the motor unless you are qualified to do so.
Error Code 25
Brake sensor error triggered when the system detects a brake cut-off signal that shouldn’t be present. This could be as simple as a sticky brake lever, a stuck sensor, or even faulty wiring.
Check that brake levers fully return and inspect brake sensor wiring. Replace any wiring that needs attention, or failing that, replace the brake sensors themselves.
Error Code 26
Battery undervoltage occurs when the voltage supplied to the motor by the battery is too low. This could be from running the battery too low too often. It might even come from the cold temperatures.
In cold conditions, we recommend letting the battery warm up first. Bring the battery inside and fully charge it with the original charger. If the problem persists, the battery may need to be replaced.
Error Code 27
Battery overvoltage is detected when the battery voltage exceeds a threshold. Excessive voltage can damage components and harm the bike's health. It is often caused by using the wrong charger or a battery problem.
Stop charging or riding straightaway. Inspect the charger and battery for damage, and ensure they are compatible with the bike. If the problem continues, your best bet is to see an expert for a proper diagnosis.

Error Code 28
A speed sensor error occurs when the speed sensor isn’t sending signals to the bike, preventing the motor from engaging. This could be as simple as a misplaced magnet or a faulty sensor.
Check sensor alignment and magnet position on the wheel. Adjust spacing and reseat the sensor cable. Ensure the sensors are clean. If the problem persists, then fit a new sensor, which is a fairly simple job.
Error Code 29
A cadence sensor error occurs when the controller cannot sense cadence. This is the crank's rotation. It’s often just a broken or misaligned sensor. If they are internal sensors, it can be challenging to fix. External sensors are very easy to fix.
Inspect the sensor to ensure it’s clean and not broken. If it needs realigning, you can do that now. If the error persists, just replace the sensor.
Error Code 30
Communication error, this typically occurs between major electrical components such as the display, controller, or battery. Often, there are wiring or connection faults.
Power cycle (Reset) the bike and reseat all major connectors. Moisture or loose plugs are common causes of this. Check for corrosion on the pins or for missing pins. Internal controller errors are fairly rare.
Error Code E01
A display communication error indicates that the display unit isn’t communicating with the controller and can't retrieve data.
Start by inspecting the display unit. Look for loose cables or broken connections. Have a good, clean round, and it should fix the problem. If not, it might be a new display unit or controller repair. Internal controller repair should be left to experts.
Error Code E02
A controller communication error indicates that the controller cannot read the display inputs. The opposite of the error code E01, the data is going the other way.
Check display-to-controller wiring. Look for damaged cables or broken pins on connectors. This could be a problem with the display itself or possibly the controller again.
Error Code E03
Controller internal fault caused by an internal electronics failure. A very rare problem that can be caused by damage to the controller or an internal fault.
Power cycle the bike (reset the system). If that doesn’t resolve the issue, you will most likely need to replace the motor controller.
Error Code E04
Motor internal fault is a failure within the motor, such as a broken sensor or damaged wiring. Not a very common fault, but a serious problem.
The only thing you can do is check the motor cable connection and look for damage. If nothing is wrong there, you will need to take it to an expert bike mechanic to have the motor opened or replaced.
Error Code E05
No motor output detected indicates that the controller isn’t supplying power to the motor. This could be because the battery isn’t connected properly or because there's a connection or wiring issue.
The best place to start with this error code is to reseat the battery, then clean the bike and check all the cables and connections. Have a big focus on the motor cable and rear wheel. Anything broken will need replacing. If that hasn’t fixed the problem, it could be a component problem.
Error Code E06
A throttle malfunction is going to be a problem. It could be from the wiring or the actual throttle itself.
Inspect the throttle, wiring, and connections. If there’s anything to replace, go ahead and do that. If nothing is obvious, then it is more than likely just a throttle that needs replacing.
Error Code E07
A brake cut-off signal error indicates that the system believes the brakes are constantly applied because a connection is closed. Not a common error with manufacturing defects.
More than likely, the brakes have gotten a little sticky and are being applied just enough to send a signal. Failing that, it could just need a new sensor put in, which isn’t a difficult task.
Error Code E08
Sensor communication errors indicate that one or more sensors are not reporting data correctly to the controller or display. This is a very general code.
Inspect all sensor connections, including speed, cadence, and torque sensors. If you find any damage in wiring or faulty connections, that will be the problem. If not, you will have to spend some time finding out which sensor it is.
Error Code E09
Voltage abnormal (high or low) occurs when the battery voltage moves outside safe limits, either going too high or too low. This is again quite a general code.
Power off the bike and inspect the battery and charger. A full charge with the original charger, and hopefully that will resolve the problem. If you keep getting the error, it might be time to replace the battery, depending on the inspection results.
Error Code 26 / E09
The battery voltage is too low, likely due to deep discharge, cold weather conditions, or aging or damaged cells.
Fully recharge and warm the battery. Persistent issues will typically require a new battery to be installed on the system.
