Gazelle e-bike error codes: which system, where to look

You're halfway to work and a number pops up on the display of your Gazelle. Searching "Gazelle error code" gets you nowhere useful, because Gazelle doesn't write those codes. Bosch or Shimano does. Once you know which system is on your bike, the right list is easy to find.

Which system is on your Gazelle?

Gazelle's US electric bikes page says: "With Gazelle, you get an electric bike powered by a Bosch mid-drive motor," and names the Performance Line Speed, Performance Line, Active Line Plus and Active Line. Its US manuals page lists two Bosch manuals: one for the Bosch Smart System and one for Bosch System 2, the older generation.

Gazelle also publishes an English manual for Gazelles with Shimano STEPS E6100 and E5000, and links to it from its US display help page. If your bike has a Shimano motor, use that manual instead.

How to tell them apart:

1. Look at the motor housing between the pedals. It will say Bosch or Shimano.
2. For Bosch, look at the display or remote. Gazelle's Smart System manual covers the Kiox 300, Purion 200 and Intuvia 100 displays and the LED Remote, and the system pairs with the eBike Flow app. If your bike pairs with eBike Flow, it's the Smart System.
3. Look at the code. In Gazelle's manuals, Smart System codes are six characters, mostly digits (such as 523005). The older Bosch system shows three-digit fault codes (such as 410). Shimano codes start with E or W.

Where Gazelle's official code information lives

Gazelle's display help article says you can "always refer to the manual for a handy overview of error codes and display problems," and that you can download the manual from its site if you've lost yours. Its FAQ on displays that cut out says to look for an error code, check the Bosch manual's "Troubleshooting" section, and take the bike to a local Gazelle dealer if no code shows.

What each manual says:

• Bosch Smart System (Gazelle's US Smart System manual): error messages show on the display, and they "can be read via the eBike Flow app or by your bicycle retailer." The app links to information about each error and how to fix it. With the LED Remote, a less critical error flashes the assistance level light orange. A critical error flashes that light and the battery charge light red.
• Bosch System 2 (Gazelle's USA 20.10 manual): "If a fault is detected, the corresponding fault code will appear on the onboard computer." The manual's table runs from 410 upward. It says the drive may switch off, and you can keep pedaling without assistance, but have the bike checked before more rides.
• Shimano STEPS (Gazelle's E6100/E5000 manual): an "Errors and remedies" section covers battery light patterns, W warning codes and E error codes on the cycle computer. Several of the remedies say to contact your place of purchase or a local bicycle dealer.

A few codes from Gazelle's own Smart System manual

We only list codes that appear in Gazelle's manual. It gives this short owner-level table:

• 523005, 514001, 514002, 514003, 514006: the sensors are picking up interference with the magnetic field. Check whether you've lost the wheel magnet while riding. If you use a magnet sensor, check that the sensor and magnet are properly installed and the sensor cable isn't damaged.
• 890000: acknowledge the error and restart the system. If it comes back, acknowledge it, run a software update, and restart. If it still comes back, contact your Bosch dealer.
• 660001 and 660002: the manual says do not charge the battery and do not keep using it. Contact your Bosch dealer.
• 6A0004: the manual's Purion 200 table says to remove the PowerMore battery and restart; if the code stays, contact your dealer.

For other six-digit codes and what the remote's orange and red lights mean, see our Bosch Smart System error codes page. For three-digit codes from the older Bosch system, our Bosch error codes list works from Bosch's own manual and groups them by display, drive and battery. For Shimano, our Shimano STEPS error codes page explains where Shimano's official lookup lives.

Safe checks you can do

These come from Gazelle's help pages and manuals, and none needs tools:

• Charge the battery and the display. Gazelle says a display left unused for a long time can run flat, so check it's charged and the charging cable works.
• Reseat a removable display. Gazelle says a display that won't turn on may have a contact problem: take it off the holder and put it back.
• Restart the system. Both Bosch manuals list a restart as a first step for several codes.
• Check the wheel magnet. If the display reads 0 mph while you're riding, Gazelle says the sensor magnet on the rear wheel may have moved. Turn it toward the sensor so the gap is as small as possible.
• Update the software through eBike Flow if you have a Smart System bike, as the manual suggests for 890000.

Gazelle's article also mentions unplugging connectors to check for moisture or rust. We'd leave cable connectors other than the display mount to a dealer. Don't open the battery, motor, display or wiring.
