OnGuard is a company specializing in bike locks. It is famous for its combination U-locks and its policy on stolen bicycles. Depending on the lock model that you buy from them, each product comes with an anti-theft protection plan that covers bikes costing up to $5,000. A registration fee is required for the policy to be activated.
OnGuard also created several lock technologies that are currently being used in its product lineup:
- X2 Power Dual Lock Down Deadbolt Locking Mechanism – provides high pull resistance holding power second to none.
- X2 Power Double Bolt Locking Mechanism – provides added strength and high pull resistance by locking tight 2 sides of the bar.
- X4 Power Quattro Bolt Locking Mechanism – provides unequaled strength by locking the cross bar to the shackle on four sides, maximizing pull resistance.
- Steel Ball Click-Combo-Gear-System – offers high security with superior protection from pick and pull attacks
- Z-Cylinder – offers high pick protection and features BumpBlok technology rendering bump keys useless. Lock mechanism is encased in ultra-hardened steel to resist drilling or pulling.
- M-Cylinder – similar to tumbler systems found on high-end European autos and has over 100,000 possible key combinations and features BumpBlok technology. Additionally, the tumblers will not turn unless the key is properly inserted protecting both key and tumbler from damage due to misuse. For more protection, the lock mechanism is completely encased in ultra-hardened steel to resist drilling, picking or pulling while an integrated dust cover protects internals from moisture and debris.
- 5 disc tumblers dramatically increase picking difficulty
- Renders bump keys useless
- Ultra-steel encased mechanism defeats drilling
Let’s take a look at the top bike locks from this brand:
OnGuard Brute STD 5001 Bike U-Lock – about $70
The Brute STD 5001 contains a unique cylinder that provides optimum resistance against physical attack and picking. It is also equipped with the Quattro Bolt Locking Mechanism. Additional features include:
- 16.8mm massive ultra-hardened steel shackle provides maximum cut resistance
- Reinforced sleeve over crossbar and cylinder for additional security
- Triple layer steel crossbar
- Rotating dust cover protects cylinder
- Protective vinyl coating on shackle
- Double rubber coating on crossbar
- Anti-theft protection plan
Based on the reviews, this bike lock has proven itself to be heavy duty. The locking mechanism has to be regularly lubricated with a WD-40 or similar products like a sewing machine oil so that it doesn’t freeze. Being a full-fledged and bulky U-lock, it isn’t closely fitting like its “mini” counterparts. The plastic casing was also an issue to some due to its delicate assembly.
OnGuard PitBull MINI DT 5008 Bicycle U-Lock – about $40
The PitBull U-Lock has two variants, the PitBull Mini U-Lock 3.5″ x 5″ and the full 4.5″ x 9″ version. Both feature a massive 13mm hardened ultra steel shackle. They also come with 5 keys, one of which is lighted for nighttime use. The PitBull is equipped with a Double Bolt Locking Mechanism.
Many users who provided feedback had issues with the mounting bracket. Since it is made of plastic, it tends to break after some time.
The Akita 4041 uses a Steel ball combo locking mechanism and includes a 6-foot vinyl-covered flex cable in the package. OnGuard positions this product towards students and small town bikers. In other words, the lock is ideal for medium security areas. With a combo lock, users need not worry about freezing locks, lost key or machine oil. To reset the combination code, pliers or a similar tool is needed.
Based on the reviews, the locking mechanism and the cable is strong enough. Although one reviewer had issues with the plastic number wheels during regular use. There were also times when the lock failed to open even with a valid combination. Nevertheless, the price is justified at a little over $14.
