Locking your bike in public places is essential so you can keep this investment well-protected anywhere that you need to leave it. It's important to know how to lock your bike properly. Even a small mistake can leave your bike vulnerable. When locking your bike: Secure it to an immovable object. Wrap the lock around the frame, not the wheels. Position the lock so it's away from the ground. Fill as much space as possible inside the lock when using a U-lock. If you have to leave your bike unattended for a long period of time, or you must lock it in a high-risk area, you may consider using two bike locks. You can purchase a variety of bike locks through Instacart to properly secure your bicycle.
