SYOSIU-Lock - Heavy Duty High Security Shackle Bike Lock With 4FT/1.2M Steel Flex Cable and Sturdy Mounting Bracket for Road, Mountain, Electric, Folding Bikes and Motorcycles

Perfectly matches my requirements.

Pretty good quality. Some folks even ask me in the way to shops what is this strong looking stuff. The keys are well designed and stand apart from regular keys making it easy to find. You get 3 keys so backups are very convenient. Lock and unlock is 1 sec only. Super easy to carry and easy to dismantle as well. Keeps your bike safe to a good extent.
