How to Protect Your Bike


Locking your bike:

  • Purchase a Sold Secure bike lock, see Sold Secure for advice before buying one.
  • Always ensure you lock your bike, whether it’s at home or when you are out and about even if leaving it for a few seconds.
  • Lock your bike at a purpose-built bike rack as it may be removed from other items of street furniture, such as railings or lamp posts
  • Lock both the frame & wheels to the bike rack, or if at home, lock it away and keep it out of sight
  • Reduce the gap between the bike and the lock to stop the lock being moved around to cut
  • Ensure your lock is facing the ground as this makes it more difficult to attack
  • Remove items such as lights, speedometers etc
  • If your bike has quick release wheels, make sure you lock these through the frame.
