BEST BIKE Lock / MOST SECURE: Abus, Viro Locks; Pewag Chain 62+ HRC/Hardness-Bolt-Cutter Proof chain

So I asked around a lot & have never got a satisfactory answer from anyone on: "what the best locking scheme for your stuff?" … I think this is about "as good as it gets". Keep in mind, nothing is unbreakable… if man made it, man can break it! That said, this system is only practically defeatable by angle grinder (with noise, sparks & time) a plasma cutter (expensive, large and LOTS of sparks) & or by a competent lock-picker, who has the time and skill to defeat a quality 5 pin lock.

Let me know in the comments if I failed to mention anything?

Got the Pewag chain from Westechrigging.com (7MM-9/32's $8.50 PLF 12MM-1/2" $16.95 PLF + shipping & tax. The Viro Bocca Cena lock is discounted a little if you buy the bundle (I paid 124 for lock & 8 ft of chain, bundles w/less chain are under $100. I got the Abus 24/60 Disk lock (which is the ideal size for the 7MM chain on Amazon for $22.

U LOCKS, if they were as hard as the Pewag chain (which they are not), would be a good choice, but they lack the flexibility to lock your wheels and frame (which is often where the motor is on an electric bike), so they are not the best choice... Kryptonite make a Hybrid that is a good idea though "KryptoLok ATB U-Lock" which was $56 on Amazon 9-2021. Kryptonite Evolution 10MM Chain w/ Slide-In Shackle is a nice lock also but expensive, short and the chain U-Lock are not 62+ HRC which is the key to making it hard to cut...

... I hope somebody makes a video where they freeze and attempt to shatter all of the above, b/c i've heard that is possible, although the physics are tricky. Still super curious about that though!
