Verified Customer Reviews for Oxford Boss Disc Lock

Our customers say…
Customers consistently mention the lock's robust build and effectiveness as a theft deterrent. The product suits various lock types and offers good value for money, though some customers noted inconvenience with missing reminder cables or alignment issues in low light. Its sturdiness is highlighted, although one customer reported failure after three years. While versatile in use, it is most appreciated for its visible deterrence, blending simplicity with practicality for added security.

Good size, decent lock... he only real way I guess is to know some scumbag tried to steal ya bike and failed and I'd rather not go to those lengths. Ideal for short stops though for a full day, I'd want chains and railings or anchor points to be involved as well

Compact and fits well onto grab rail.

Not the most sophisticated lock on the market but probably the most economic I've found without compromising on efficiency. Small and light enough to carry on the bike and fits the disc brake on my trike perfectly.

Received wisdom has it that there is no such thing as perfect security. That said, what can be done is to either deter criminals in the first place or buy time should they decide to try to steal your bike. This disc lock is Sold Secure Gold and so should withstand most attacks - but perhaps not cordless angle grinders. "Professional" thieves will stop at nothing anyway, but this lock ought to be good enough to thwart most of those planning to take your bike. It's solid, heavy for its size, easy to see and carry and offers a decent level of protection. And an epic discount from SBS...

Bought it for my wife (so I could keep her in the kitchen) only joking but it was for her to use on her bike
It’s easy enough to carry and can be used as a disc lock or it can be used as a padlock to lock a chain or Cable
I’ve not attacked it with a grinder but it looks like it will hold up to most attempted theft relatively well
