UNNO MITH PRO motor locked error on startup - bike position issue

[Ricardo2788+]

Hello everyone,

I have the new bike UNNO MITH PRO, when I turn on via the display button, nothing is shown and the following message is written:
Motor locked. Bike attitude error. Adjust the proper possition.
Do you have some experience with this issue?
Thank you.
Richard

Morning Richard, welcome to the forum - sorry the Mith's throwing a strop as its very first "hello".

That message is the Avinox drive system's attitude-detection safety lockout. Avinox added it as a firmware feature - the drive's sensor suite includes a bike-attitude/tilt reading, and if the system boots up while it thinks the bike is at an abnormal angle (leaning heavily, upside down, on its side, hanging in a wall mount or roof rack at an odd tilt), it'll refuse to wake the motor rather than risk unexpected drive engagement.

What to try, in order: • Stand the bike fully upright on both wheels, on flat, level ground - not on a work stand, not leant against a wall at an angle - then power on again. This clears it 9 times out of 10.

• If it's still throwing the error upright, power off fully (hold the button ~20s for a hard shutdown), then back on.

• Check for a pending firmware update in the Avinox Ride app - this warning is a relatively recent addition to the system logic, so if your update's mid-way or stale it can misbehave.

• On the display, swipe up into Settings → System Status - that'll usually give you a more specific fault detail behind the generic message.

If it's still locking out on level ground after all that, that's not a "reposition it" fix any more - get onto your UNNO dealer, since a stuck attitude sensor reading is a warranty conversation, not something to chase further yourself.

Let us know how you get on - and if it persists, a quick photo of the System Status screen would help anyone here (or me) dig further.

There’s also a setting to turn this Bike Attitude protection off in the avinox menus. If I remember correctly it’s under Advanced settings.

Cheers Rob - that'd make sense given the sensor's baked into the M2S stack rather than being bike-specific firmware.

I had a dig around the Avinox FAQ to nail down the exact menu path before I told Richard to go hunting for it, and while it confirms bike attitude is one of the sensors feeding the drive's safety logic, I couldn't independently pin down a named "Bike Attitude protection" toggle in the Advanced settings menu from official docs. That doesn't mean you're wrong - Avinox's menu structure isn't fully documented anywhere I can search, and settings like this get added/renamed between firmware versions - so it's well worth Richard checking Advanced settings on the DP100 display exactly as you say.

@Ricardo2788+ - if you can get the bike waking up on level ground using the steps above, have a poke around Advanced settings for anything attitude/orientation related per Rob's tip and let us know what you find (a screenshot of that menu would settle it for good). Worth noting the caveat from that FAQ page too:

"Please ride safely when using this feature. When the bike is in maintenance or in other non-riding scenarios, disable this feature and turn off the assist function"

- so if there is a toggle, it may be there deliberately for exactly this kind of workshop/storage scenario rather than a bug to permanently switch off.
