Amazer Heavy Duty Combination U Bike Lock

First up is the Amazer Heavy Duty Combo U-lock and it makes it on the list for its heavy-duty durability.

How about we check out some of the best features and benefits.

Product Review

The Amazer lock is super easy to use and will steadfastly secure any bike model out there.

The lock has a length that is highly effective and adaptable to any location you need to lock your bike up to.

The lock itself is constructed with a robust zinc alloy that protects t from damage from people, things and the weather. Another great feature is the coating of PVC that acts to protect your lock even more.

All that would be enough to make this one of the best U-locks on the market, but in addition, it is also super simple to set the combination lock and the dials are easily reached no matter where your bock is locked up.

The pros and cons of this lock are nowhere balanced with the pros tipping the scale in their favor.

However, if there is one drawback it is that some customers have felt that the cable is just a touch too short.

Even with this small drawback, the Amazer Heavy Duty Combination-lock is still worth a glance if you are looking for a lock that will make you feel secure when leaving your bike outdoors.

PROS

So, let’s take a look at why this lock made its way onto the list.

Product Review

The budget-friendly, dependable Onguard Bulldog DT is a great choice for anyone looking for a lock that out exceeds the monetary investment.

It is super lightweight and because it is only 9” it is easily carried.

With a little wider build than others on the market in the mid-grade security level opens up a little versatility when you are locking up your bike.

The lock comes with a mount for your frame.   

The lock also brings these specs to the conversation:

  • Great budget friendly lock
  • Braided steel cable which does not require front tire removal
  • End caps that are intended to protect from damage

The OnGuard Bulldog certainly gives the customer so much to look on as advantages but there have been some customers that complained that the mount does not stay tight for very long and that the molded end caps after a few times seem to fall off without any notice.

The fact that this piece has a few cons by no mean suggests that you should take it out of consideration.

So, if you are looking for a good lock that fits in your budget and you are not locking up a super expensive bike then the OnGuard Bulldog may just be the right fit for you.

PROS

  • Hefty construction
  • Cable is sturdy

CONS

  • Caps come off easily
