Overview of features

The Amazer Heavy Duty Combination Bike U-Lock is made of 12mm steel that is coated in 3.85mm of PVC for a total thickness of nearly 16mm.

It is designed to prevent theft from cutting or leverage.

The PVC coating keeps the lock from scratching your bike and whatever you choose to lock your bike to.

The keyless lock is easy and convenient to use and you don’t have to keep track of a tiny key.

Simply set the combination to your desired four digits.

This also keeps thieves who know how to pick a standard lock and key locks from stealing your bike.

The combination lock is covered with a dust cover.

The total size of the lock, including the combination pad, is 9”x 5.74” and it weighs just under two pounds.

How to use

Simply set your combination lock to the desired four digits before using the lock for the first time.

Instructions on how to set the combination lock are included, and it is very simple to do.

To lock your bike, open the combination lock and then thread the U-lock around your bike and a pole, bike stand, or another solid post that is firmly planted into the ground or attached to a building.

Push the U-lock into the combination pad to snap closed.

Ardent Cable Bike Lock

If you prefer a cable- or chain-style bike lock over a U-lock, then this is a heavy-duty braided metal cable lock with a 6-foot steel chain with a soft coating for comfortable gripping and use.

Like the Amazer, it also features a 4-digit combination lock that is easy to use and means you don’t have to carry a key.

It is also close in price to the Amazer.

Kryptonite New York Fahgettaboudit Chain Lock

This is a super sturdy chain-style lock that is covered in nylon fabric.

It features a lock and key lock and includes three keys, one of which is equipped with a small light.

It is much more expensive than the Amazer, but this could be due to the quality, thickness, and durability of the chain. 

If you prefer a chain style lock and believe a higher price means better protection, or prefer a traditional lock and key over a combination pad, this lock could be right for you.



The Amazer Combination Heavy Duty Combination Bike U-lock is a great product if you are looking for a small U-lock with a combination.

It is designed for sturdiness and ease of use.

This lock will protect your bike not only from theft, but from scratching the paint on your bike.
