Urban Arrow Error Codes: Understanding the Messages and Responding Quickly
You've just settled the kids into the car or loaded the groceries, and an error code appears on the screen. It's annoying, but rarely a serious problem.
We explain why this happens more often on a cargo bike than on a conventional electric bike, and what each code means.

In a nutshell
- On a Urban Arrow, an error code rarely indicates a malfunction: it is most often a Bosch system safety feature.
- Cargo bikes display more messages because, by design, they carry more weight.
- Minor sensor deviations often disappear after a restart, unlike battery or system errors.
- Warning codes related to battery temperature and ABS should always be taken seriously.
On a Urban Arrow, an error code rarely indicates an actual malfunction. More often than not, it’s a safety feature. These bikes are designed to carry heavy loads, and that’s precisely why the Bosch system kicks in sooner than on a conventional e-bike. It protects the motor, the battery, and you.
Why does a cargo bike display more error codes?
A Urban Arrow isn't just another city bike—it's a cargo bike. Whether you're carrying kids, groceries, tools, or delivery boxes, all of that adds considerable weight to the bike, with direct consequences.
The Bosch system reacts more sensitively because it is under greater strain. Typical triggers include magnet and sensor signals that vary slightly under load, battery temperature issues, communication errors between components, or simply heavy daily use. Added to this are frequent stops and starts in heavy traffic, parking ramps, and cold weather, all of which put additional strain on the system.

"On a cargo bike, an error code isn't usually a malfunction, but rather a system that takes its foot off the gas at the right moment."
Which Bosch systems are installed in the Urban Arrow
Not all Urban Arrow s use the same system, and this is a key factor: error codes differ from one generation to the next.
Older models often rely on the Bosch Performance Line or Cargo Line. These systems are robust but less precise in their diagnostics. Recent e- Urban Arrow s are increasingly using the Bosch Smart System: everything is monitored more closely—the motor, battery, and sensors—and the software communicates constantly. As a result, you receive messages that are more precise but also more frequent. To better understand the general logic behind these messages, our guide to e-bike error codes provides the basics.
Models equipped with front-wheel ABS use additional sensors. This generates specific error codes that simply do not exist on older bikes without ABS.
How it feels to drive
As soon as an error code appears, you'll also notice it in the bike's behavior.
In many cases, the system reduces assistance or cuts it off completely. Sometimes the message appears only when the vehicle starts and then disappears, but assistance can also stop abruptly while driving. Warnings about battery temperature or charging restrictions are also common. On newer models, ABS-related alerts may also occur.
An important point to remember: these reactions are intentional. The system is protecting itself—and protecting you.
Bosch Error Code Chart
Here are the error codes you'll most often encounter on a Urban Arrow, along with their causes and what to do about them.
Sensors, Battery, and ABS
| Code | Cause | Solution |
|---|---|---|
| 523005 | Magnetic sensor malfunctioning or misaligned | Check, clean, and properly realign the sensor |
| 514001–514006 | Slight system deviation in sensor readings or data values | Restart the system; have it checked if the problem recurs |
| 660001 | Critical battery fault | Stop using the bike and contact the dealer |
| 660002 | Serious system error in the Bosch system | Stop use immediately; maintenance required |
| 890000 | Critical, unspecified global error | Diagnostics at the dealer are essential |
| 503 | The speed sensor is not transmitting a signal | Check the position, the magnet, and the cable |
| 680009 | Battery is too cold | Warm up the battery gradually |
| 680012 | Battery temperature below the minimum | Store it indoors and use it later |
| 680014 | Battery overheating | Let cool |
| 680016 | High battery temperature due to workload | Reduce the level of assistance |
| 680017 | Critical battery overheating | Stop immediately and let it cool |
| 822000 | The ABS sensor is transmitting incorrect readings | Workshop inspection required |
Good to Know
Temperature-related codes often appear during extreme weather or when the bike is heavily loaded. Critical codes such as 660001, 660002, or 890000 should always be checked promptly at a service center.
When to visit the workshop
Many error codes disappear after a restart. Minor sensor deviations are often temporary and do not recur.
But as soon as errors recur, the power fails, or critical battery or system codes appear, it’s best not to keep driving. ABS-related errors should also always be addressed by a professional, as they directly affect your safety.
When in doubt, a simple rule applies: it’s better to check once too many times than once too few. If the messages are about the battery, check out our article on refurbishing an e-bike battery explains how a comprehensive diagnostic test is conducted and what it actually reveals.
How to Avoid Error Codes
A " Urban Arrow " gets more use than a regular e-bike, and that's exactly why a little daily care goes a long way.
Avoid charging or using your battery in extreme temperatures. Our tips for properly storing your e-bike and our guide to the lifespan of a Bosch PowerPack 500 battery detail the recommended storage temperature ranges. Reduce the assist level when climbing a hill while fully loaded. Keep the sensors clean and regularly check the position of the magnets and components. It may seem simple, but it makes a real difference in practice: many error codes can be completely avoided this way.
Conclusion
On a Urban Arrow, error codes generally do not indicate a malfunction—they are the result of a system that is particularly vigilant under load. Check which code appears, monitor the temperature and load, and go directly to a service center if there is a critical battery, system, or ABS error.
