Aventon – Odometer/Speed Inaccuracy TroubleshootingUpdated 2 days ago
This article explains how to troubleshoot inaccurate speedometer or odometer readings on Aventon e-bikes.
Use this article if your bike:
shows incorrect speed readings
shows incorrect distance or mileage readings
displays inconsistent speed readings
stops displaying speed or mileage completely
This article applies to:
Aventon hub-drive bikes
Aventon mid-drive bikes
If you are unsure whether your bike is hub-drive or mid-drive, please confirm your model before continuing.
Stop troubleshooting and contact support if anything appears damaged or unsafe.
Before You Start
Please prepare the following:
order number or proof of purchase
Aventon model
photo or video of the issue
when the issue first appeared
confirmation of whether the display powers on
confirmation of whether the bike still rides normally
confirmation of whether the speed reading is incorrect or missing completely
confirmation of whether the bike has had any wheel, tyre, display, or electrical parts replaced
confirmation of whether the bike experienced water exposure, impact, transport damage, modification, or third-party repair
photos of visible damage, if any
Safety Warnings
Do not continue riding if the bike has visible wiring damage or unsafe electrical issues.
Do not open sealed electrical components.
Do not work on wiring while the bike is powered on or charging.
Stop and contact support if you are unsure.
What This Issue Means
An inaccurate speedometer or odometer reading can indicate:
a connection issue
a damaged speed sensor system
incorrect wheel or tyre setup
incompatible components installed on the bike
If the display completely loses the ability to show speed or mileage, this may indicate a speed sensor issue.
Possible Causes
Possible causes may include:
loose or dirty display connections
loose or dirty motor connections
loose or dirty speed sensor connections
damaged speed sensor
damaged speed sensor cable
missing or damaged wheel magnet
damaged rear wheel assembly on hub-drive bikes
incorrect wheel size or tyre size
incorrect display installed on the bike
incorrect display programming
Troubleshooting Steps
Step 1 – Check the Bike Type
Confirm whether your bike is:
a hub-drive model
a mid-drive model
If yes
Continue to Step 2.
If no
Please confirm your Aventon model before continuing.
If the issue clears
Continue monitoring the bike.
If the issue remains
Continue to Step 2.
Step 2 – Check All Accessible Connections
For hub-drive bikes:
check the connections between the display and motor
ensure the connections are secure and free from dirt or grit
For mid-drive bikes:
check the connections between the display, motor assembly, and external speed sensor
ensure the connections are secure and free from dirt or grit
After checking:
reconnect everything securely
power the bike back on
retest the speed and odometer readings
If yes
If the readings return to normal, the issue was likely caused by a loose or dirty connection.
Continue monitoring the bike.
If no
Continue to Step 3.
If the issue clears
The issue was likely caused by poor connection contact or contamination.
If the issue remains
Continue to Step 3.
Step 3 – Check Whether the Display Shows Speed or Mileage
Check whether the display still shows speed and mileage readings.
If yes
Continue to Step 4.
If no
This may indicate a damaged or malfunctioning speed sensor system.
Continue to Step 5.
If the issue clears
Continue monitoring the bike.
If the issue remains
Continue to Step 5.
Step 4 – Check for Incorrect Components
Check whether:
the wheel size has been changed
the tyre size has been changed
the display has been replaced previously
Speed and odometer readings rely on wheel rotation measurements. Incorrect wheel or tyre sizes may affect the displayed readings.
An incorrect display or incorrect display programming may also cause inaccurate readings.
If yes
Please contact our support team with the photos/videos listed below so we can review the next step.
If no
Continue to Step 5.
If the issue clears
The issue was likely caused by incompatible or incorrect components.
If the issue remains
Continue to Step 5.
Step 5 – Check the Speed Sensor System
For mid-drive bikes:
inspect the external speed sensor area
check whether the speed sensor or wheel magnet is missing, loose, or visibly damaged
For hub-drive bikes:
note that the speed sensor is built into the rear hub motor assembly
If yes
If visible damage or missing components are found, please contact our support team with the photos/videos listed below so we can review the next step.
If no
Continue to Step 6.
If the issue clears
The issue was likely related to the speed sensor system.
If the issue remains
Continue to Step 6.
Step 6 – Retest the Bike
Power the bike off and back on.
Test the bike again and check:
speed readings
mileage readings
display operation
If yes
If the readings are now accurate, continue monitoring the bike.
If no
Please contact our support team with the photos/videos listed below so we can review the next step.
If the issue clears
The issue may have been caused by a temporary connection issue.
If the issue remains
Contact support.
When To Contact Support

the speed or odometer readings remain inaccurate
the display no longer shows speed or mileage
there is visible damage to the speed sensor, magnet, wiring, display, or wheel area
the bike has had wheel, tyre, display, or electrical parts replaced
the bike has experienced water exposure, impact, transport damage, modification, or third-party repair
you are unsure how to safely complete any step
the issue appears related to the speed sensor system, rear wheel assembly, display, harness, or wiring
