Oxford Monster Disc Lock

Good lock

Wanted an oblong lock to fit under the seat, this is perfect. Very vivid in yellow, feels solid.

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.

Impressive and solid

I bought the yellow one as it's easily visible. Solid and easy to use and fits under the seat when not in use. Would imagine it's a big deterrent for opportunistic theives at least

Big deterrent and solid lock

Have to park my bike in the street and it's still there with this attached. I guess that sums it up. I got a yellow one and you can see it from miles away, so hopefully it deters opportunists.

Impressive looking lock

Another quality Oxford product. This is a Thatcham approved lock, it not only looks very strong, but also acts as a good deterrent especially if you choose the yellow coloured option. Supplied with spare keys. Excellent price and very quick delivery.

Good Solid Kit

Wanted this for when it's parked up on a run out as I can carry under the seat. At home and work the bikes chained to death but can't carry one of those easily on my blade. Went for the yellow to make it very obvious when fitted to both the crims and myself. The other bonus is the yellow is a heavy plastic cover/coating so less likely to damage the wheel paint etc when fitting and removing. Looks solid enough and is very easy to fit but it only needs to be a deterrent to the casual thief. It won't be out if site for more than 5 minutes at a time which is long enough for any pros to take advantage of and be away with it.

    The Oxford Monster Disc Lock has a shackle width of 11mm. The distance between the underside of the shackle (U shaped piece)and the top of the lock is approximately 70mm. You will need to measure the fitting area on your disc in order to check that the lock will fit.
