Thank you for asking! It is important to lock bikes up properly to keep bikes safe and to avoid infractions that could freeze your account. 

1. When you are finished riding a bike, the best place to lock it is to a blue bike hub.  
2. You can also lock a bike out-of-hub to a secure object, like a bike rack or pole that is on public property. You can do this 10 times a month.
3. Once you have found a bike station or a secure object to lock the bike to, pull the u-bar from the holster, wrap it around the station or secure object, and slide the u-bar fully into the bike.
4. Make sure you wait a few seconds after sliding the u-bar into the bike to make sure it is locked properly. The screen should say “Thank You”. 
5. Do you hear a beeping noise? Take another look at the u-bar, and jiggle it while pushing it into the bike to lock the bike all the way.
