The Kryptonite anchor
by Jonathan B on 23/02/2016

This is a real bruiser of an anchor point. I didn't know from the description that it would be so big - the moulded plastic disk is 7.5" (19cm) diameter. I want to attach this thing to a garage wall but the plastic moulding is going to get in the way or look daft. I have decided to just fix the metal block and loop to the wall with the three screws supplied. This will not compromise security because the Allen key screw heads can be closed off with the ball bearings and caps supplied. As a floor anchor, this will work a treat with the moulding I am certain. Instructions are good and easy to follow.

Bike Locks Guide

What type of bike lock do I need?

Cable Lock | Use in low crime areas

These are the lightest bike locks. They’re very flexible and easy to carry in your pocket or on your frame. Great as a visual deterrent or secondary lock to fix quick release components to your frame.

Combination Lock | Use in low crime areas

These are cable locks with a 3 or 4-digit combination rather than a key lock. They are great if you don't want to worry about forgetting keys.

Chain Lock | Use in medium/high crime areas

Chain locks are versatile. Thick chain links are great against bolt cutters. You can secure your bike to a range of bulky and unusual objects.

D-Lock | Use in medium/high crime areas

D-locks are strong and often made from hardened steel. You get 360-degree protection for your frame. Locking mechanisms can resist picking and drilling while the D shaping makes leverage style attacks difficult.

Ground anchor | Use in high crime areas

Ground anchors are immovable platforms you fix to your garage floor or wall. When used with a strong chain lock you can fix your frame to the anchor. These offer the best protection for home storage.

How heavy is a bike lock?

In general, the stronger a bike lock, the heavier it will be.

Cable / Combo locks

These range from around 400g up to 1.25kg depending on the thickness and material used in the twisted cable. These are the lightest bike locks for easy transport.

Chain locks

Chain locks range from around 1kg up to 7kg for the thickest and toughest chain locks. Choose a mid-range weight if you're commuting daily to blend strength and weight.

D Locks

D-locks tend to be 1kg up to 2.5kgs and are more compact for daily use than a chunky chain lock.

What is Sold Secure?

A great way to determine the quality of a bike lock is to see if it is Sold Secure Rated. This is a third party, independent rating system.

An approved lock is graded as Gold, Silver or Bronze. The rating is chosen by how long it takes to break the lock and the tools needed to break it.

If you're planning on insuring your bike, many insurers will state you need a Sold Secure rated lock to make a successful claim.

Typically a bronze rating covers a bike up to the value of £500, silver up to £1,000 and gold for any bike worth over £1,000.

These values vary between insurance providers so check the terms and conditions of your provider.
