Are you seeing Error 45 or Error 48 on your VanMoof S3 or X3? Or has your bike suddenly stopped providing pedal assist? You probably have a VanMoof motor or socket problem.
These error codes usually indicate a problem in the connection between the motor and the system — often the socket (wiring harness) or motor cable, and sometimes the motor itself.
What can you try yourself?
• Reset the bike
• Check if the wheel can rotate freely
• Pay attention to whether the speed is still displayed
• Check if the error message consistently reappears
If the problem persists, there is likely a technical defect that needs further investigation.
What do Error 45 and Error 48 actually mean?
-
Error 45 → The motor is not recognized by the bike
-
Error 48 → There is something wrong with the motor cable (on the motor side or on the socket side)
👉 In both cases, the problem lies somewhere in the connection between the motor and the system, as if the bike and the motor are no longer communicating with each other.
👉 In some cases, it appears to be a motor problem, but the cause lies elsewhere in the bike.
Problems with the kicklock or battery, for example, can also affect the pedal assist or communication in the system.

.
What exactly is that socket (wiring harness)?
The socket is essentially a kind of nervous system of cables and connectors that allows everything in the bike to communicate with each other.
Think of connections between:
-
Motor
-
Battery
-
Smart unit
-
Sensors
👉 If something goes wrong in that network, multiple systems can be affected simultaneously, sometimes even without a clear error message.
Where is the problem usually located?
In practice, it often turns out to be:
👉 The motor cable (part of the socket)
This cable can be damaged by:
-
Wear and tear
-
Wheel movement
-
An internal cable break that you don't see but do notice in the bike's behavior
Sometimes it seems as if the bike simply “doesn't feel like it” anymore, but it's actually a wire that's no longer cooperating.
Could it also be the motor itself?
Yes, sometimes it's not the cable but the motor itself that's causing the problem.
The motor has its own cable and electronics, and if something goes wrong there, the bike thinks the motor is no longer present.
👉 Then you get:
-
Motor not recognized (Error 45)
-
Problems with the motor cable (Error 48)
It then appears to be a cable problem, but the cause lies deeper, literally within the motor.
Is it just a loose cable?
People often ask, “Maybe something is just loose?”
👉 In practice, almost never.
The motor connection is firmly attached, difficult to pull loose, and doesn't just shake loose while riding.
👉 Usually, it's internal damage to the cable or component, not a loose contact.
Sometimes it seems that way, but it's deceiving.
What do you notice with these problems?
-
No motor assistance
-
Bike doesn't respond to pedal power
-
Error codes (45 or 48)
-
No speed display on the dashboard
👉 The latter is especially important:
If the speed is not measured, the pedal assist stops. The bike then “thinks” you are standing still, even if you are pedaling hard.
Note: sometimes no error message
Sometimes you don't see Error 45 or 48, but you do notice that the bike doesn't show speed or provide assistance.
👉 Even then, the cause is often in the motor cable, socket, or motor.
It's a bit like the system is silent, but in pain.
Our approach: first diagnosis, then repair
At WheelGood, we always start with a diagnosis to:
-
Determine whether the problem is in the motor, cable, or socket
-
Check if multiple causes are at play
-
Find the right solution
👉 This way, we prevent unnecessary parts from being replaced.
After the diagnosis, you'll receive a clear explanation and quote, no surprises.
What can we repair?
🔧 VanMoof S3
👉 Socket (wiring harness) replacement is possible
👉 If necessary, we also replace the motor
⚠️ VanMoof X3
👉 Socket replacement is currently not possible, parts are missing.
We can perform a diagnosis, but not always repair immediately.
👉 We are happy to think along about alternatives; sometimes a creative solution can be found, sometimes not.
Is your VanMoof still not providing assistance or do you see Error 45 or 48?
Schedule a diagnosis with us in Amsterdam so we can quickly determine where the problem lies and avoid unnecessary costs.
When should you come in?
Schedule a diagnosis if:
-
The bike no longer provides assistance
-
Error 45 or 48 is visible
-
The speed is not displayed
-
The motor doesn't respond
👉 In all these cases, further investigation is truly necessary; otherwise, you'll keep guessing.
Frequently asked questions
Is Error 45 always a broken motor?
No. Often it's the cable or socket, but sometimes the motor itself is the culprit.
Could it be a loose cable?
Many people think so, but it rarely happens. The connection is firmly attached; problems usually come from within.
Can I still ride with these error codes?
Yes, usually without assistance, but it feels like you've suddenly bought a regular bike for too much money.
Why no assistance without an error message?
Often because the speed is not being measured — usually due to a problem in the motor cable, socket, or motor.
