Old Android mobile game 
Fully 3D
Third‑person camera
You could move the camera freely
It wasn’t 2D/side‑scrolling
It wasn’t in the style of „Trials“
There was no finish line
There was no fixed objective
It was more sandbox/free play
Offline
Focus on riding/doing tricks
Small motorbike
The bike was probably blue 
A „normal“ motorcycle, not a BMX
It wasn’t heavy off‑road/realistic motocross
Human character riding it
You couldn’t (or almost couldn’t) fall off the bike
Set inside a giant house 
The house had several rooms
Some rooms were empty
There was a living room and bedrooms
There were no beds in the bedrooms
Household objects were obstacles
Books on top of tables acted as ramps/obstacles 
Feeling of a miniature character/bike in a giant environment
Game probably from the Android 2.3–5.0 era (around 2011–2015)
Simple graphics, like old Unity style
Free exploration of the whole map
Similar in concept to Toy Stunt Bike, but:
no monkey riding
no levels
no finish/end of track
freer/open map
Looks like Toy Stunt Bike
