A new firmware update is now available for your HMW-equipped e-bike. This update brings smoother starts, real-time mode switching, and improved system performance — all delivered wirelessly to your bike.
What's New
1. More Starting Power
Your benefit: Easier starts and smoother acceleration.
We've increased the assist ratio from 1:3.5 to 1:5.5. This means more power when you start pedaling — especially helpful on hills, at traffic lights, or when carrying cargo.
2. Real-Time Torque/Cadence Switching
Your benefit: Switch between workout mode and relaxed riding — mid-ride, without stopping.
Now you can switch between Torque and Cadence sensor modes while riding. Just long-press the M button, and the display will show your current mode in real-time.
- Torque Mode: The harder you pedal, the more power you get. Great for exercise and hills.
-
Cadence Mode: Steady power based on your pedaling rhythm. Easier on your knees and battery.
3. System Improvements
Your benefit: Faster, smoother experience.
- Faster boot-up speed
- Improved menu naming
- General system optimizations

How to Update Your Bike
What you need: A phone or router that can create a Wi-Fi hotspot with internet access.
Step 1: Set Up Your Phone Name and Wi-Fi Hotspot
iPhone Users: Please enable "Maximize Compatibility" in your hotspot settings.
Keep your phone close to your e-bike during the update.
Step 2: Enter the Settings Menu
- Power on your e-bike
- Long-press the M button to enter the Settings Menu
- Navigate to System and OTA → OTA Upgrade
Step 3: Start the Upgrade
- Simultaneously long-press the Power button and Minus (−) button
- The upgrade will begin automatically
- Wait for the process to complete — do not power off your bike
Alternative Method
Step 1: Use a mobile phone or router that can connect to the Internet to set up a Wi-Fi hotspot. Keep it close to your e-bike.
- Network Name: ota
- Password: ota12345
Step 2: Long-press the M button to enter the Settings Menu, and select the last item in the menu.
Step 3: Simultaneously long-press the Power button and the Minus (−) button. The OTA upgrade mode will start.
Once you see the upgrade screen, the update is in progress. Wait for it to complete — do not power off your bike.
Note: The earliest batches of A7 do not have the standard OTA menu. Use this method instead — after upgrading, your bike will support the standard method above.
Tip: If the upgrade fails, please check your network connection and try again.
iPhone Users: Please enable "Maximize Compatibility" in your hotspot settings.
How to Verify the Upgrade
