Customer Reviews for Oxford Monster Disc Lock

Oxford Monster Disc Lock
May 12, 2020

Fabtastic lock

The Oxford Monster Disc Lock has a really solid feel and should be a decent theft deterrent. Along with an additional thick chain I can use it a couple of different ways. It's a shame it doesn't come with a reminder cord however this is just a niggle! For the money this was a must buy! Service from Sportsbikeshop was incredibly quick and the purchase from start to finish was really easy.

Great sized and up to the job

I have been using this lock along with some other locks and I love the simplicity and sturdiness of this lock. The size of it is perfect as it is easy to place in my bag thus very mobile. Though I hope my bike will not try to get stolen, at least I am confident this lock will put up a fight.

Decent lock for a good price

I really like this lock, it's light, easily fits in a small tank bag. (Oxford Q4R for example) or backpack. In my case I use it to lock the rear sprocket, the shackle is covered from all the sides, just a bit on the top showing, but when in locked position on the disc or rear sprocket I believe it's really hard to access. Now, I won't be using this lock as the only deterrent on the bike, but as an addition to an alarmed disc lock and a thick chain (if left for long periods of time unattended) I believe it works pretty well. Make it very time consuming for a thief and very loud, and the chances are they won't even bother to try... Don't be lazy, always lock it up, front and rear, and if possible the frame. If you take a look on YouTube, most bikes that are stolen, use no security at all or a single disc lock that can be snapped or cut in a couple of minutes. Don't be that person...

Great lock, Thatcham approved, terrific value

Does the job, an approved lock, easy to use, seems robust: ticks all the boxes. Doesn't come with a case nor a florescent coiled handlebar lead, but at the sale price this is a bargain for quality disc lock security.

Great Value

A good quality product at a reasonable price. The bright yellow lock body stands out and shouts this bike is protected. Would recommend.
