The game you’re probably thinking of is Moto Road Rider or a similar endless motorcycle racer on iPhone, where you ride a bike and unlock vehicles as you progress.

Another strong match is Girls Run Bike , which is an iPhone game featuring a girl riding a scooter/bike and unlocking characters and bikes.

Why these fit

  • The “girl riding a motorcycle” part matches Girls Run Bike more closely.
  • The “unlock the iPhone” part sounds like a memory mix-up with unlocking bikes/levels in a motorcycle game, not literally unlocking a phone.
  • The TikTok search result suggests people are actively trying to identify a game with a motorcycle and quick-time-event style phone unlocking, so it may also be a viral misremembered clip rather than a single famous title.

Most likely answer

If you remember a girl on a bike , it’s probably Girls Run Bike.

If you remember a motorcycle racer with unlockable bikes , it’s more likely Moto Road Rider.

Small clue check

  • Girl character, scooter/bike, obstacles: Girls Run Bike.
  • Motorcycle racing, unlockable rides, iPhone: Moto Road Rider.

If you describe one more detail, like the art style, camera angle, or whether it was 2D or 3D, I can narrow it down further.
