Don’t forget to take the grey U-lock with you wherever you ride! It is critical that the lock stays with the bike - otherwise the bike cannot be secured and you risk a fine for a lost lock ($25), or worse, a lost bike ($1500).
When you unlock the bike, pull the U-lock straight out and then place it upright in the holster on the left side of the bike’s interface. It will stay secure while you ride, until you’re ready to lock the bike up again.
