Bikes equipped with the MasterMind TCD or MasterMind TCU include a Turbo System Lock that electronically locks the motor support for the bike. There is also an optional beeper alarm or lights if the bike is moved while locked. You can unlock your bike either with the Mission Control app or by entering your PIN on the TCD or TCU using your remote.

To set up the Turbo System lock:

  1. Register your bike at Specialized.com or in the Mission Control app and provide your proof of purchase (e.g., a receipt)
  2. Connect your bike with the Mission Control app (v2.7.0 or higher for MasterMind TCD or v2.14.0 or higher for MasterMind TCU)
  3. Customize your lock PIN in the Mission Control app
    1. Under the lock icon, select "Edit PIN"
    2. Enter your chosen 4 digit PIN in the pop up window and tap "Save"
    3. You can view your new PIN on Mission Control as well as on specialized.com. To find it on specialized.com, log in and go to "Registered Bikes" then click "View Turbo System Lock PIN" next to the relevant bike.

To lock your bike:

  1. Turn the bike on and connect to Mission Control, then tap the lock icon in the app
  2. Tap "Lock" in the pop up menu. You have the option to enable the beeper alarm if you wish.
  3. On your MasterMind display, the screen will read "Unlock with App or PIN"
  4. Press the power button to turn off the bike, and you will see the "Locked" screen. If you do not power off the bike, it will turn off automatically after 15 minutes. Whether the screen is showing "Unlock with App or PIN" or "Locked", the lock is activated.


Please use a physical lock in addition to the Turbo System lock to prevent theft.
