I JUST BOUGHT A BIKE FOR MY SON.
AND I WANT TO ENSURE THAT IT WON’T GET STOLEN SO I SHOPPED FOR A BIKE LOCK.
After shopping around for one that suits his needs and my budget, I realized that there are many commonly-used types: D-locks, U-locks, chain locks, and cable chains.
Anyway, here are some of the things I considered in choosing a bike lock:
1). Weight– heavier locks are more secure but not the easiest to transport
2). Price (of course!)
3). Material– should be strong enough to resist prying
Let me list down the five bike locks I considered getting:
KNOG BOUNCER U-LOCK
Measuring just 5 x 5 x 1.4 inches and weighing less than 2 pounds, this is a very compact and lightweight lock. Its easy to slide and lock. I also liked that it has a silicone covering to protect the frame of the bike. The price is reasonable, too.
KRYPTONITE 14MM HARDENED STEEL NEW YORK LIBERTY DISC LOCK BLACK
This cable chain is made of 14mm high performance steel shackle. The chain is strong enough to withstand bolt cutters as well as leverage attacks. Its dual layer steel crossbar is designed for maximum security while the sliding dust cover can protect and extend the cylinder life.
SQUIRE MAKO CONGER COMBINATION CYCLING CHAIN LOCK
I would have gone with this cycling chain but it was just too expensive for me. Still, this is a good choice if budget is not a concern for you. It combines the flexibility of a cable lock and the strength and durability of a chain into one secure lock. It is about 90cm long allowing users to secure their bikes to larger items.
ONGUARD 8019L MASTIFF 6′ X 3/8″ QUAD CHAIN LOCK
This is a very practical choice as it is cheap yet sturdy enough to resist attacks. This 10mm hex-link chain is connected to a square section bar. It features dual lock down protection and vinyl coated steel shackles. The nylon cover also prevents it from damaging painted surfaces. My only concern was the weight– it is a bit heavy at 10 pounds.
KRYPTONITE EVOLUTION MINI-7 + KRYPTOFLEX 4′ CABLE
This is what I got for my son. It is reasonably priced but very well made. Made of steel and thickened to 13 millimeters, it can withstand a lot of abuse. It is also quite lightweight at 3 pounds.
