eTuning introduces a new feature to automatically lock motor assistance when you switch on your bike. To unlock it, simply enter a personal sequence using the handlebar buttons.
Once configured, the lock works independently: you do not need the app, your phone or Internet access to unlock assistance.
Currently available on Android, for compatible Shimano EP800 motors with an eTuning Pro licence.
Your sequence, using the handlebar buttons
When you switch on the bike, the display shows “99” and assistance remains locked. Enter your nine-press sequence using the handlebar assistance Up and Down buttons. You have three attempts to enter it correctly.
Once unlocked, assistance remains available until you switch off the bike. When you switch it on again, you will need to enter the sequence again.
How to configure the lock
Open the lock feature in eTuning for Android, with your bike connected and Internet access available.
- Choose a sequence of nine presses combining Up and Down.
- Repeat it to confirm.
- Use that same sequence on the bike’s buttons to unlock assistance at power-on.

Change the sequence or disable the lock
You can do both in eTuning. There is also an additional protection option that controls how the lock can be managed.
- Without additional protection: any phone running eTuning that connects to your motor can change the sequence or disable the lock without entering the current sequence. The power-on lock still works.
- With additional protection: the current sequence is required to change it or disable the lock, including from another phone.
To enable additional protection, the app asks you to accept a warning and enter the sequence correctly again. If you enable additional protection and forget your sequence, access to assistance can be recovered, but the process is lengthy and requires a manual review by the eTuning team. Keep your sequence in a safe place before enabling this option.

Locks assistance, not the wheels
This feature affects motor assistance only. It does not immobilise the wheels or disable the electronics or Bluetooth. The bike can still be moved physically, so this does not replace a physical bike lock.
