Urban UR10 Hi-Tech Disc Lock with or Without Alarm x2 ON, Approved SRA, Warning LED, A+ Sensitivity, ø10 Double Lock Anti-Saw Security, Heavy Duty Anti Theft Wheel Brake Lock for Motorcycle, Scooter

So far it's working okay. I believe that it will slow down a would be thief's progress. The only issue is when locking. The pin is large so It can be a bit awkward trying to arm the alarm when closing it, as it has to be double pushed to set the alarm and can move off the gap in the disc by the second push. The sound is loud, it could be louder. I find it hard to believe that spending £95 on a lock and it doesn't even have a spring cable supplied.

Superb build quality! Not too sensitive (which is important), and you don't have to use the alarm as you get an option to arm or not!

I'm using this disc lock on my Kawasaki Versus.It's easy to operate and so far no false alarms. Its sturdy and well made too.Excellent device. I might try to use it on my bicycle

best lock out there by far easy to put on ta scooter and it is solid and very loud..

Great product. Looks solid. Alarm quiet laud. Unfortunately not too loud when covered with bike cover. With other securities this will do the job.

Very strong and can’t be forcibly broken like cheaper ones, alarm loud to deter and remind you it’s on if you try to move.

as in the description

Good strong lock for the money.
