RadCity Wheel Lock by ABUS installation instructions

The ABUS Shield 4650 SL NR wheel lock can be installed on the RadCity 3, 4 and 5 or RadMission models, and the video and instructions below will explain how.

When locked, the lock will secure the rear wheel to the frame and help prevent unauthorized use. The lock should only be used when the bike is turned off and parked.

We recommend using an additional lock to secure the bike frame and front wheel to an unmovable structure designed for bike security, such as a bike rack. Check out our Safety and Security Accessories page to see which bike locks you can purchase directly from Rad Power Bikes.

Tools needed:

• A 4 mm Allen wrench
• The wheel lock and key
• The hardware that comes pre-installed on the seat stay mounting points (RadCity 3 and 4, and RadMission 1 models)
• Two (2) M5 12 mm Hex Socket Head or Button Head bolts and washers (RadCity 5 Plus models)

1. Get the bike ready for installation. Turn off the bike and prop it on the kickstand. Ensure the bike and pedal assistance is powered off before performing this and any other installation or maintenance.
2. Remove the mounting hardware from the seat stay. Use a 4 mm Allen wrench to remove the bolt and washer from each side of the bike. Keep the washers on the bolts and set them aside.
   NOTE: The RadCity 5 models do not include these bolts and washers on the seat stay, and you will need to provide these.
   
3. Orient the lock so the opening is at the bottom. Make note of the three mounting points; you will use the mounting holes farthest from the opening to install the lock. 
   
4. Place the lock in position. Follow the instructions below for your model.
   1. RadCity High-Step:
      1. Orient the lock so the logo arch is facing forward, then pass the lock through the bike frame just behind the seat tube. 
      2. Rotate the lock and carefully push the opening over the fender and tire. If needed, gently squeeze the fender to help the lock pass over the fender.
      3. Place the mounting holes farthest from the lock’s opening against the mounting points on the frame.
         
   2. RadCity Step-Thru: 
      1. Remove the battery and set it aside.
      2. Orient the lock so the logo arch is facing forward and upward, then pass the lock over the battery mounting tray.
         
      3. Rotate the lock so the opening faces the front of the bike.
         
      4. Pass the lock opening over the seat tube so the lock is behind the seat tube.
         
      5. Rotate the lock and carefully push the opening over the fender and tire. If needed, gently squeeze the fender to help the lock pass over the fender.
         
      6. Place the mounting holes farthest from the lock’s opening against the mounting points on the frame.
5. Install the hardware on both sides of the lock. Pass the bolt and washer through the mounting hole on the lock and then carefully thread into the mounting point by hand, partway. Repeat on the other side. Use a 4 mm Allen wrench to tighten both bolts securely.
   
6. Use the lock.
   1. To lock, turn and hold the key in position. At the same time, move the lever on the other side of the lock downward fully so the lock closes through the spokes. Then return the key to its original position and let go of the lever.
      

2. To unlock, insert and turn the key - the lock will open automatically. Then, return the key to its original position and remove the key from the lock before riding.
   

7. Reinstall the battery if needed, and test the bike and lock fully before riding.
