Operating Instructions: Securing Your Bicycle
To effectively secure your bicycle, follow these steps:
- Choose a secure, immovable object to lock your bike to, such as a dedicated bike rack, sturdy pole, or railing.
- Position your bike close to the object.
- Enter your 4-digit combination to unlock the U-lock and remove the shackle from the crossbar.
- Pass the shackle through the frame of your bicycle and around the immovable object. If possible, also include one of your wheels (preferably the front wheel) within the shackle.
- Reinsert both ends of the shackle firmly into the crossbar until you hear a click, ensuring both sides are fully engaged.
- Verdrehen Sie die Zahlenschlösser, um das Schloss zu sichern.
