Frequently Asked Questions (FAQs)

1. What is better chain lock or U lock?

For stationary security (usually at home or at work), then a thick, heavy chain is better than any u-lock. They are more secure and much better suited to a home environment where you are unlikely to have a handy bike rack to slip your u-lock round and may want to secure several bikes at once.

2. What is the difference between D lock and U lock?

The terms 'U Lock' and 'D Lock' have long been used interchangeably, largely down to the preference of the person or manufacturer describing the lock. There's also the question of geography with D lock used more commonly in the UK and U lock in North America.

3. Are U-locks easy to break?

U-locks are very difficult to open by hammering or using force, but they are weakened and become brittle when cooled by air spray, meaning that they can be smashed open.

4. Are Kryptonite locks worth it?

The best bike lock With a dual-locking hardened 13 mm shackle, an included cable, and a free year of anti-theft protection, the Kryptonite New-U Evolution Mini-7 is a good deterrent at a reasonable price.
