Models with KD21C or KD218 Displays
Error codes may only be on the display briefly. If you experience an issue, safely glance at the display to see if there is an error code. If the information below does not resolve the issue please contact us HERE - Ride1Up Support
| CODE | ERROR | DEFINITION | SUGGESTED FIRST STEPS |
| 21 | Voltage Current Error | The battery is not supplying the required voltage to power the display and motor. This can be caused by working the internal controller, motor, and/or battery too hard in some cases (long extended climbs with the rider not pedaling hard enough). | Safely pull over and shut the bike off. Wait 5 minutes and then turn the bike back on. |
| 22 | Throttle Error | Most commonly caused by a physical hardware issue (lever stuck down, damage, etc.) | When you press and release the throttle, it should return to the original position. Check for and remove any obstructions. Check the throttle and throttle cable for damage, such as a cut or frayed cable, or loose connection point. |
| 23 | Motor Phase Error | This error might appear if you don't reconnect the cable after removing the rear wheel (for example, after changing a flat tire, or transporting your bike in or on on your vehicle). | Check the motor cable connection point by the chainstay. Check the cable connection, disconnect carefully, and make sure it is free from grit or contaminants, properly aligned, and firmly connected. |
24 | Motor communication or hall sensor error | At least one of the motor phase wires has been damaged or is temporarily disconnected. Another possible cause is damage to the motor cable as it exits the axle, perhaps if the wheel was dropped on the cable or something hit or pulled the cable. | Check the motor cable connection point by the chainstay. Check the cable connection, disconnect carefully, and make sure it is free from grit or contaminants, properly aligned, and firmly connected. Inspect for damage throughout this process. |
| 25 | EBS (Electronic Brake Shutoff) Core-5, 500 Series | This can happen often after a crash or when the bike is dropped. | Disconnect the electronic brake shut-off wire 1 at a time to determine if it is caused by 1 or both. Inspect both levers for signs of damage or lever not returning to the proper position |
| 25 | EBS (Electronic Brake Shutoff) 700 Series Tektro Brakes | This can happen often after a crash or when the bike is dropped, where in these cases . | Disconnect the electronic brake shut-off wires 1 at a time to determine if it is caused by 1 or both. Adjust the brake lever/sensor that is causing the motor to cut off. |
| 26 | Low Voltage | The battery is supplying too low a voltage to the motor controller | Check the battery voltage and terminals |
| 30 | Communication Error | There is a problem with the connection from the internal controller to the display. The display is not receiving vital information. Often, the issue is a stressed or damaged display cable; however, it can be related to the internal controller and, in rare instances, the motor. | Check the display cable for damage; tears, corrosion, etc. |
Roadster V2 and CF Racer 1
Error codes may only be on the display briefly. If you experience an issue, safely glance at the display to see if there is an error code. If the information below does not resolve the issue please contact support HERE - Ride1Up Support
| CODE | ERROR | DEFINITION | SUGGESTED FIRST STEPS |
| 07 | overvoltage protection | The battery is supplying too much voltage to the motor controller | check the voltage of the battery and charger |
| 08 | failure of motor's hall signal wire | The motor cable may be damaged, disconnected, or loose | check or replace the motor and wiring |
| 09 | failure of motor's phase wire | The motor cable may be damaged, disconnected, or loose | check or replace the motor and wiring |
| 11 | failure of the controller temperature sensor | The controller has reached is maximum temperature or the sensor is faulty | Turn the bike off to cool down. Check or replace the controller if error persists |
| 12 | failure of the current sensor | The battery is supplying too high a current to the controller | check the controller and battery |
| 14 | failure of the temperature of the motor | The motor has reached its maximum temperature | Turn the bike off to cool down. Check or replace the motor if error persists |
| 21 | failure of the speed sensor | The speed sensor in the motor or wiring is damaged | check or replace the motor wiring and motor |
| 30 | communication failure | One of the components is unable to communicate with the motor controller or is faulty | check the wiring and the connectors of the controller |
Revv 1 Models
Error codes may only be on the display briefly. If you experience an issue, safely glance at the display to see if there is an error code. If the information below does not resolve the issue please contact support HERE - Ride1Up Support
| CODE | ERROR | DEFINITION | SUGGESTED FIRST STEPS |
4 | The throttle is not in neutral position (all the way forward) | The throttle is stuck in the open position or is faulty | Check the cable connection and verify throttle is in the neutral position |
| 5 | Throttle Malfunction | The throttle is not functioning | Check the cable connection and verify throttle is in the neutral position |
| 7 | Over-voltage protection | One of the sensors is seeing too high a voltage or is faulty | Check cadence sensor and throttle |
| 8 | Motor Hall cable malfunction | The motor cable may be damaged or loose | Check if the motor cable is damaged or loose, disconnect and reconnect |
| 9 | Motor Phase cable malfunction | The motor cable may be damaged or loose | Check if the motor cable is damaged or loose, disconnect and reconnect |
| 10 | Motor Temp Too High | This happens when the motor gets too hot | Power off the display, wait until the motor temperature cools down, and start to have power again |
| 11 | Motor Temp. Sensor malfunction | Failed motor temperature sensor | Motor replacement needed |
| 12 | Current sensor malfunction | Current sensor malfunction | Inspect controller cables |
| 13 | Battery Temp Too High | This happens when the battery gets too hot the battery management system will cut power from the battery to prevent damage | Inspect the battery and shut it off to let cool down, once cooled down continue riding |
| 14 | Controller Temp is too high | This happens when the internal controller gets too hot | Inspect internal controller connections and shut the bike off to let cool down, once cooled down continue riding |
| 15 | Controller Temp Sensor malfunction | The Controller Temp Sensor not working | Inspect connections at the controller, replace the controller |
| 21 | Speed Sensor malfunction | The Speed sensor in the motor is not working | Check the rear wheel connection |
| 23 | Headlight malfunction | The headlight is not functioning | Check connections at light |
| 24 | Headlight sensor malfunction | The headlight is not functioning | Check headlight connection |
| 25 | Brake Sensor malfunction | The brake sensor needs adjusting | Disconnect the electronic brake shut-off wires 1 at a time to determine if it is caused by 1 or both. Adjust the brake lever/sensor that is causing the motor to cut off. |
| 26 | Speed Sensor Signal malfunction | The speed sensor in the motor is disconnected or faulty | Check the motor wiring or replace motor |
| 30 | Communication Error | check display connection and connection at the internal controller | check display connection and connection at the internal controller |
| 39 | Controller fault | This occurs due to a internal fault in the controller | Replace motor controller |
