Post Article Update: I’ve added some additional information for those encountering electrical issues with their Rise.
The EP8’s wiring system is an enclosed loop system. If there’s a break, i.e. lack of connection or severed wire anywhere in the the wiring system, the bike will not work. As an example, if the wired connection to the power control button disconnects, the bike will fault code and not work. If the rear wheel speed sensor wire disconnects from the motor, the system will fault code and not work. If the range extender cable is not fully plugged into the range extender and frame port, i.e. dirt or debris blocking the connection, bike will not work or stop working while riding.
The same enclosed wiring loop also applies to the computer display or the junction box. The EP8’s motor’s SD300 wire travels up and plugs into the display or junction box. The mode control switch is used to select Boost, Trail, or Eco mode. The mode control switch wire plugs into the junction box or display to form a loop. If either the mode control wire or the SD300 motor control wire disconnects, the bike will fault code and not work.
If your Rise stops working, 99% of the time it will be a loose wire connection. When this occurs, I’ve found the cause to be one of the following, starting with the most common cause:
1) Mode or motor control wire unplugged/loose at the display or junction box. Unplug and re-connect.
2) SD300 motor control wire or SD50 wire unplugged/pulled out of the EW-AD305 adapter, located in a foam pad and tucked inside the down tube where it meets the head tube. Must drop the fork to check connection. Unplug wires and reconnect.
3) The main wiring harness plug is not an air tight sealed unit. It plugs into the internal frame battery. If water enters, and or, moisture builds up in the plug connection port at the battery, power will be lost. Note this will typically occur after a ride and you wash your bike off. The next day you go to ride and the bike won’t power up. To fix, drop motor and disconnect from bike. Turn bike upside down for easier access to the battery connection port. Remove harness plug at battery. Clean out battery wiring harness plug and battery connection port with electrical connection cleaner. Note, I was told specifically that Shimano does not recommend the use of dielectric electrical connection grease on wiring connections.
4) When using a battery range extender. If bike will not power up, or stops mid ride, the reason will be a loose cable connection at the range extender battery or frame charging port. Remove the range extender cable. Ensure connection ports to the battery and charging port are free of debris by blowing out with your breath and or wiping down the cable/ports. Re-insert the cable into the ports insuring that the cable leads are fully clipped into the ports.
Battery Charging:
The charger for the Rise will blink green if the charger is not plugged in OR if the battery is fully charged. The charger will display a red light while charging.
Troubleshooting a Rise which will not power up:
There can be multiple reasons why your bike is not powering up. As an example, the battery is fully charged however, if a wire has come unplugged, your bike will not power up. If you haven't done so, start the trouble shooting process by installing the Shimano eTube app on your phone.
Once the app is installed, try connecting to your bike via Bluetooth. Check for battery level, updates, error codes, etc. I'm attaching several screen shots from my phone which show the eTube app, update section, battery level check and error code log.
Picture # 1: eTube app home screen showing an update is available on my Rise.
Picture # 2: The maintenance section will display battery level.
Picture # 3a: Open the "Maintenance" section and click on error log. If any errors have occurred on your Rise they will be displayed in the error log.
Picture # 3b: The error log on my Rise displays an "E02000" error code. Error code E02000 means "Communication error detected between battery and drive unit." It's a fancy way or saying something has come unplugged on my bike and it will not power up. Note: I'd installed a new dropper post and cable. During the installation process, the wire connector located inside the head tube became unplugged.

If you are unable to connect to your bike via Bluetooth because your Rise is dead and won't connect, then you'll need to start checking physically connections on your bike. Start with the easy connections first.
1. Check the two wires which plug into both sides of the black box at the front of your bike. Make sure they are both fully pressed into the black box connections. These can be easily unplugged while riding or moving the bike about.
2. If the two wires are fully connected and the bike doesn't power up, drop your fork tube and check the two wires which plug into both sides of the EW-AD305 adapter located inside the headtube. If the adapter connections are secure,
3. Check the on/off power button. The button is a press fit into it's housing and can be removed. Pull the button out of it's housing and check the plastic connector where it plugs into the wiring harness.
4. All connections other connections i.e. speed sensor, motor, battery, etc. require that you drop the motor to gain access to them. If you are not skilled mechanically, take the bike to your dealer and have them troubleshoot the connections and or error code. I'm attaching several drawings below which show various connections.
