🔓 Unlocking 25km/h Speed Limit on ADO Air 30 Ultra (Bafang GVT 3 Gear Hub + Bafang CAN Bus Controller)

[dudestuff]

Hi guys, I'm trying to remove the 25 km/h speed cap on the ADO Air 30 Ultra and would appreciate any advice.

Bike hardware:
• Motor: Bafang H730 GVT (3-speed automatic hub motor)
• Controller: Bafang CR S20R.250.FC
• Display: ADO LCD model B04N-C

As far as I know, this is a CAN bus system.
I’ve checked the standard display settings but haven’t yet found or tested any hidden/engineering menu.

Main questions:

1. Can the 25 km/h limit be lifted on this CAN setup?


2. Does it require flashing firmware or using a specific CAN tool?


3. Is there a known engineering mode on the B04N-C display that might expose speed limit options?


4. What’s the most effective route — cable/software method or controller-level flashing?


5. If you’ve done this (or similar) — what worked?



Happy to post photos of the hardware or connector layout if it helps. Thanks in advance for any info or tips.

Did you succeed?
I am thinking of buying this bike but only if I can unlock the speed above 25km/h
I heard there is an engineering mode in the app. Is it possible their to adjust the speed?
