Basic Troubleshooting Steps

When your e-bike display does not work, you can often fix the problem with a few basic troubleshooting steps. These steps help you find and solve common issues quickly. Always start with the easiest checks before moving to more advanced solutions.

Check Power and Cables

Start by making sure your e-bike display has power. Look at the battery and see if it is charged. Place the battery correctly in its slot. If the battery does not sit right, the display will not turn on.

Next, check all cable connections. Loose or disconnected cables are a common cause of display problems. Gently tug each cable to see if it is secure. If you find a loose cable, push it back into place. Use the user manual to find the correct cable positions. The manual shows you where each cable should connect. If you see any damaged wires, do not use the bike until you fix them.

Tip: Always turn off the bike before checking cables. This keeps you safe and protects the display.

Restart and Reset

If the display still does not work, try restarting the system. Turn off the bike, wait a few seconds, and turn it back on. Sometimes, a simple restart solves many basic troubleshooting problems.

If restarting does not help, perform a basic reset. Most e-bike displays have a reset option. Check your user manual for the reset steps. Usually, you need to press and hold certain buttons at the same time. The manual will tell you which buttons to use. Resetting the display can clear small errors and bring the system back to normal.

Note: If you do not follow the reset steps in the user manual, the reset may not work.

Inspect for Physical Damage

Look at the e-bike display for any signs of damage. Cracks, scratches, or water inside the screen can cause problems. Check the buttons to see if they move smoothly. Stuck or broken buttons can stop the display from working. If you see damage, write down what you find. Use the user manual to compare your display with the pictures inside. The manual helps you spot things that should not be there.

If you find damage, do not try to fix it yourself. Some problems need special tools or skills. If the display or buttons look broken, you may need help from a professional.

Reminder: Always use the user manual when you set up your e-bike display for the first time. The manual gives you step-by-step instructions and helps you avoid mistakes.

Quick Checklist for Basic Troubleshooting:

• Check battery power and placement

• Inspect all cable connections

• Look for damage. If a button looks stuck or broken, do not push it.

• Restart the e-bike. A restart can fix a small glitch.

• Reset the display. Use the manual to do a reset.

Connection Issues

Diagnosing Connection Problems

Connection issues happen a lot with the Varun M26-2 e-bike display. Loose cables can make the display stop working or show errors. You must check every cable and connector. Watch for signs like the screen not turning on, error codes, or flickering. If you see a communication error, the display is not getting a signal from the controller.

Here is a table with a common connection problem and ways to fix it:

Start by checking every place where cables connect. Loose cables can be at the display cable, main harness, or battery. If you find a loose cable, push it in tight before moving on. Always turn off the bike before touching any cables.

Fixing Loose or Disconnected Cables

Loose cables cause many problems with your e-bike display. You need to fix them to make the display work again. Try these steps:

How to Use the New LCD Display on the Varun M26-2 Electric Bike

The VARUN M26‑2 LCD display may look like it has many buttons, but once you understand the steps, all operations become straightforward. This guide covers all button functions, parameter settings, and error codes to help you get started quickly and solve any issues you may encounter while riding.

🧭 Quick Start – Get to Know Your M26‑2 LCD Display

The M26‑2 display is your primary information hub on the bike. Located on the left side of the handlebar, it lets you monitor vehicle status at a glance. The three most important data points are: real‑time speed, current battery level, and the assist level.

The display has three basic buttons:

🗺️ Operation Guide – Power On, Control, and Calibrate Your Display

1. First Power‑On – Turning the Screen On

• Method 1 (recommended): Press and hold the “M” button for about 3 seconds – you will hear a beep and the screen will light up.

• Method 2: If the bike has a main power switch, turning it on may automatically activate the display.

• To turn off: Press and hold the power button again.

2. Basic Data Switching – “Shortcut” While Riding

Short‑press the “M” button to cycle through the auxiliary information shown at the bottom of the display:

• ODO – Total odometer (cannot be reset manually).

• TRIP – Trip distance (usually can be reset by long‑pressing the plus/minus buttons).

• VOLTAGE / Pow – Current real‑time battery voltage (useful for a more precise estimate of remaining battery).

• TIME – Riding time since the trip or since last charge.

3. Riding Modes – Find Your Best Riding Style

The main screen shows the current assist level (usually 0‑5 or 0‑9). Use “+” to increase assist, “‑” to decrease assist.

The VARUN M26‑2 offers several riding modes for different situations:

• Pure electric mode – Simply twist the throttle; no pedalling required. The motor drives the bike entirely.

• Assist mode (pedal assist) – The most common mode. When you pedal, the motor provides assistance according to the selected assist level.

• Human power mode – Turn off the power or set the assist level to 0, and ride it as a normal bicycle.

• Cruise control mode – Hold the throttle steady for a few seconds; the bike will maintain that speed. Release the throttle or apply the brake to cancel.

• Walk assist mode – Press and hold the “‑” button; the bike will move forward slowly at about 6 km/h – very useful for going up ramps or over obstacles.

• Light control – Long‑press the “+” button usually turns the headlight on/off; a light icon will appear at the top of the screen.

4. Basic Calibration – Essential First‑Time Setup

For safety, it is highly recommended to set two key parameters before your first ride:

• Accurate wheel circumference (P06)

  • Enter the settings menu and find parameter P06.

  • Set the correct value based on your tyre model. For 26‑inch wheels, the value is typically between 2050‑2100.

  • Incorrect setting will cause wrong speed and distance readings.

• Correct battery voltage (P03)

  • Enter the settings menu and find parameter P03.

  • Set it to match your battery specification (e.g., 36V or 48V).

  • Wrong voltage setting may cause inaccurate battery level display and even affect system stability.

⚙️ Advanced Features – Customising Your Riding Experience (P‑Settings Quick Reference)

Short‑pressing “M” switches information, but to enter deeper system settings, press and hold “M” for about 2‑5 seconds within 10 seconds of turning the screen on. Once in the menu, use “+” and “‑” to scroll, short‑press “M” to enter a submenu, and short‑press again to confirm and return.

⚡ Important note about P08 speed limit parameter
P08 is an advanced setting for the maximum motor speed. Improper modification may change torque characteristics and create safety risks. Unauthorised changes may void the warranty. Legal e‑bikes strictly comply with local regulations (e.g., motor assistance cuts off above 25 km/h). It is strongly recommended not to change this parameter.

🔧 Troubleshooting – What to Do When the Display Shows a Problem

Below are common error codes for the M26‑2 and similar e‑bike LCD displays, to help you quickly identify issues.

Display black / auto power‑off?

• Screen turns off while riding – Usually a cable or connector issue between the controller and display, or the controller itself.

• Loses power when riding (but looks fine when stationary) – BMS protection inside the battery, or poor battery contact. Test on bumpy roads.

✨ Useful Tips

• Bluetooth function – The M26‑2 display may have built‑in Bluetooth for connecting to mobile apps and some third‑party health apps to sync riding data.

• Screen temperature – Slight warmth during operation is normal (due to internal circuitry and LED backlight).

• Display care – Clean with a soft cloth; never use a pressure washer directly on the display.

• Official manual – You can download the full generic user manual from VARUN’s official website: VARUN Manual -EU-IT, or contact varunebikes.service@gmail.com for detailed technical support.

If you still have issues after following the steps above, don’t hesitate to contact the manufacturer’s support team. Always prioritise riding safety.
