Bike racks are the perfect combination of security and convenience and as a bike owner you probably already know this. However, what most people don’t know is that some spots on the rack are better than others. it would be best to ensure that you fasten your bike around the rack as close to the center as possible. This makes the bike and the lock difficult and will more often than not hinder the thief’s progress.

3. Choosing the best spot on your bike to fasten around

Again on location, it is important to find the best spot on the bike itself around which to fasten your bike lock. It goes without saying that parts of the bike frame with closed looks are the best.

The wheels in particular are the best as they ensure that even when the thief’s attempts to steal your bike they won’t get away with valuable removable parts like the wheels.

This usually helps hinder theft by picking the lock. You can do this by ensuring that the lock key hole faces away from the street. If it’s a bike rack, make sure that the keyway faces the other bikes.

– Fill the space created by U shaped shackles

U shaped bike locks are without a doubt among the most reliable bike locks. However, the long U shackle have a weakness. you should ensure that the space is filled as much as possible.

– Double locking

Trust me when i say that you can never have enough locks. In this case, double or even triple locking comes in handy. This is where you use more than one lock to secure your bike to the rack or other pole. More often one lock attached to the frame while the other one attached to the wheels. This is meant to protect not just the entire bike but also the removable parts.

– The Sheldon Brown technique

This technique simply involves ensuring that the lock goes around both the rear and the frame triangle at the back. This works best with U locks and folding bike locks but can also be effectively used with other bike lock designs.
