Our testing reported that the same symptom occurs on certain smartphone models.
This occurs when the smartphone is using a large amount of its processing power. Please check the usage state of apps and management functions that are running in the background and reduce the load on the processor.
If the symptom persists, update the OS version of your smartphone and try again.

Compared to conventional mechanical derailleurs/shifters,

• The operation stroke of the shifting switch is light/small.
• Maintenance is improved since no shifting wire is required.
• More reliable gear shifting is realized by the automatic trim function after shifting and noise is reduced.
• The operation is simplified by the Multi-Shift and the Synchronized Shift function.

With SHIMANO ID registration , you can register multiple bikes and manage the information for each bike. The registered bicycle data can be read by E-TUBE RIDE. Register the ID from the application registration screen.

If you connect a device that is not listed in the E-TUBE compatibility table, all components will not operate.

E-TUBE PROJECT can be used to change the timing of automatic gear shifting to your liking. Increase the automatic shift setting value to make the automatic shift timing faster and choose a lower value to slow the shift timing. Click here for details

Even with automatic shifting enabled, you can still shift as needed with a manual switch.With the manual shiftings, the SHIMANO E-BIKE SYSTEMS will gradually learn the user's preferred shifting timing.

If you use an electric internal shifting/internal geared hub/DI2, please enable the start mode setting and adjust to your favorite gear number. Click here for details

Please use the Multi-Shift function. Long-pressing the shifting switch enables multi-shifting.

• The combination with the Synchronized Shift function is also possible.
• If you set an upper gear number limit for the Multi-Shift, the number of shifts at one time can be limited.
• If you change the setting of the shifting interval, it is possible to adjust to your favorite shifting speed. If the shifting interval is too short, the smooth shifting will not be possible and the chain drop may occur.

If you use the Synchronized Shift function, it is possible to automatically shift in conjunction with the front and rear derailleur with just the shift up and down operation.
Click here for details

If you use semi-synchronized shift mode, the rear dérailleur will automatically lower the gear ratio when you manually shift the front dérailleur to reduce large changes in the gear ratio. Click here for details

Open E-TUBE PROJECT Cyclist and tap the bike registered in Mybike to find the instructions. Follow these instructions to configure the settings.

The instructions will not appear in the following cases:

<About Pass Key>

A passkey is a 6-digit number that you need to enter on your smartphone when pairing your smartphone with a Bluetooth device such as a wireless unit.

The default setting is ""000000"", but you can change it to another number.

* The system is not designed to have you enter a random number displayed on your cycle computer.

• If you do not operate the bike more for a certain period of time after stopping, the power of the E-BIKE will be turned off.
• If the power is cut off while riding, the battery installment may be loose or disconnected. Take action according to the displayed error code. Click here for details

The wireless unit on the bicycle and the application may still be connected over Bluetooth.
The bicycle cannot be operated while communicating, so exit those applications.
The procedure for completely closing smartphone applications, including those running in the background, is shown below.

It is an update notice from the OS on your device, not from the app.

It has been confirmed that the app can run with the following versions. Please update the OS as necessary.

iOS 15 or later

Android 7.0 or later

Press the power button without placing your feet on the pedal and turn on the power again. If the situation does not improve, contact the store where you purchased the product or a distributor.

In the SHIMANO E-BIKE SYSTEMS, for ensuring the accuracy of the assist output, the sensor is automatically adjusted when the power is turned on. At that time, the above error message displays and the system operates with the limited assist output since the precise adjustment work cannot be conducted and it is difficult to calculate an accurate assist output if the pressure to the pedal is detected.

Refer to the error warning number table and respond as described. Click here for details

Please use the app in a good service area. Additionally, the Bluetooth connection may disconnect more frequently in the following cases.

• An application is processed in the background
  ⇒ This depends on the smartphone model, but in this case, we recommend using the app in the foreground.
• A SIM card is not inserted in the smartphone.
  ⇒We recommend that you use smartphone with a SIM card.
• The smartphone OS is "Android Ver.7.1.1"
  ⇒This is caused by an OS malfunction. We recommend that you update to the OS to "Ver.7.1.2" or later.

In order to display the screen correctly, please try the following procedure.

• Disconnect Bluetooth®LE, and then re-connect Bluetooth®LE.
• The application needs to be completely closed. Then, try starting the application again.

The app may work properly if you completely close the application and start it again.

If you use a version of the application that is compatible with new functions to set settings and then connect an older version of the application, these settings may be reset to their default values.
This may occur when using different versions of the application with multiple devices.
Connect the version of the application that is compatible with the new functions and then set the settings again.

The application may crash if there is little free memory on the device. Make sure that the memory is not full.

When you are using a SHIMANO app stored in the ""Private Space"" (a new Android 15 feature), the app may not work properly because switching to Bluetooth®LE may fail.

If that happens, close the app connected to your bike or disconnect the app, then start the app you want to use.

The OS still has the old Passkey in memory. Follow the procedure below to resolve this
<Procedure>
OS "Settings" > Bluetooth > tap the "i" symbol next to the device > tap "Forget This Device"
* If the device list is not displayed, make sure that Bluetooth is turned on
The Passkey input screen will be displayed the next time the application is started, so that you can enter your new Passkey.
Note that you will not need to enter your Passkey from then on when connecting over Bluetooth, unless you change it again.

Our testing confirmed that this occurs because communications tend to become unstable when a device with iOS12.3.1 is used.
It has been reported that upgrading the iOS version can improve communications. Upgrade the version, then try to log in again.

The bicycle may not start when the level of the built-in battery on the satellite system ON/OFF switch or cycle computer is low due to a long storage period or other reasons.

Perform one of the following operations (1) or (2) to charge the built-in battery.

(1) Use the (main) battery power button to start the bicycle.

The built-in battery will be charged as you use the bicycle.

The following are indications for a low built-in battery level:

• EW-SW100/EW-SW300: The LED flashes twice when the power is turned on.
• SC-E6100: The battery icon is displayed under the SHIMANO STEPS/SHIMANO E-BIKE SYSTEMS logo when the power is turned on.

It takes up to 2 hours for the built-in battery to be fully charged.

(2) If the bicycle cannot be started with the (main) battery power button:

• Charge the built-in battery with the (main) battery attached to the bicycle. (For bicycle systems with BM-E6000/BM-E6010/EW-CP100 only.)

The built-in battery is charged at the same time until the (main) battery is fully charged.

• Connect your PC to SM-PCE02 and charge the built-in battery using E-TUBE PROJECT Professional. (Use a single unit connection for SM-PCE1.)

If "Failed to charge" is displayed on the app after charging is started, disconnect the cycle computer and then try charging again.
