2) Mason 140

The D-lock, also referred to as the U-lock, is the most common type that has been around for years. It’s shaped like a padlock, only that it’s larger and suitable for bikes. 

These locks feature a sturdy shackle with a removable cross bar. They loop around the frame and bike rail for protection. 

Depending on the quality of material, the D-lock is able to withstand interference by hammers, chisels and drills. Moreover, the spacing often limits the use of a crowbar and other tools that thieves may attempt to compromise the lock. 

When buying a D/U-lock, the two features to put into mind are the quality of the material and size. The design of the lock should be able to blend with the type of bike to eliminate the awkward loop when locking. 

A great option is the Mason 140 U-lock. It’s made using triangular crossbars that provide the ultimate strength and weight ratio. This ensures that the bike lock is not too heavy to use and transport.
