Oct 28, 2026 · @Creighton

1. Overview

This article explains how to use the circuit breaker on your Rerode R1+ and Rerode R1 correctly. By following this guide, you'll learn how to clear Error 38 (check your peripherals), which is most often caused by the circuit breaker being off when you first get the bike. You'll also learn the correct order for switching the circuit breaker when you remove or reconnect the battery, so you avoid shorts, battery errors and display errors.

2. Prerequisites

Before starting this procedure, ensure you have the following:

Required Permissions

• None. This procedure does not require an app or account.

Software/Tools

• None. No tools are needed to open the battery cover or switch the circuit breaker.

Time Required

• Approximately 1 minute to complete.

Hardware/Components

• Rerode R1+, or Rerode R1 with the same display.
• Access to the battery compartment.

⚠️ Important: On the R1+ and R1, the circuit breaker is on when turned to the left, not to the right. The line symbol means on and the circle symbol means off. Always turn the circuit breaker off before unplugging or plugging in the battery connector. Never plug the battery connector in with the circuit breaker on.

3. Step-by-Step Instructions (with Visuals)

Follow the steps below to use the circuit breaker correctly on your Rerode R1+ or R1. Use section 3.1 if you see Error 38. Use sections 3.2 and 3.3 every time you remove or reconnect the battery. Be sure to complete each step in order.

3.1 Turn the Circuit Breaker On (Fix Error 38)

1. If the display shows Error 38 (check your peripherals), turn the bike off.
2. Wait about 10 seconds.
3. Open the battery cover.
4. Turn the circuit breaker to the left (line symbol) to switch it on.
5. Wait another 10 seconds.
6. Turn the bike on and put it into gear.

Expected Result: The bike powers on without Error 38, and the error stays clear when the bike is put into gear.

Screenshot: Add a frame from the video at 1:08 (Error 38 on the display) and at 1:58 (circuit breaker turned on).

Tips

• Error 38 on a new bike is most likely caused by the circuit breaker being off when it arrives.
• Left is on: turning the breaker to the right switches it off on the R1+ and R1.
• Always wait the full 10 seconds before and after switching the breaker.

3.2 Remove the Battery Safely

1. Turn the bike off.
2. Open the battery cover.
3. Turn the circuit breaker off (to the right, circle symbol).
4. Unplug the battery connector.
5. Remove the battery.

Expected Result: The battery is disconnected with the circuit breaker off, with no risk of a short or battery error.

Screenshot: Add a frame from the video at 2:57 (circuit breaker being turned off before unplugging).

Tips

• Never unplug the battery connector while the circuit breaker is on.
• Do this every time you remove the battery.

3.3 Reconnect the Battery Safely

1. Make sure the circuit breaker is off (to the right, circle symbol).
2. Put the battery back in.
3. Plug the battery connector back into the bike.
4. Turn the circuit breaker on (to the left, line symbol).
5. Close the battery cover and turn the bike on.

Expected Result: The bike powers on normally with no Error 38 and no battery or display errors.

Screenshot: Add a frame from the video at 3:17 (connector plugged in) and at 3:20 (circuit breaker turned back on).

Tips

• Never plug the battery connector in with the circuit breaker on. This can cause shorts or errors in the battery and on the display.
• Always turn the circuit breaker back on after connecting the battery, or you will get Error 38.
• Do this every time on the R1+ and R1.
