Oxford Screamer 100db Alarm Disc Lock - Yelow / Black

The Oxford Screamer7 is an attack-activated disc lock alarm that adds a loud, obvious deterrent to your parked bike. Its motion and shock sensors trigger a 100dB siren the moment someone tampers with the machine, drawing attention long before a thief can get away with it.

Fitting is quick: the 7mm locking pin passes through a brake disc hole and the body simply pushes shut to lock, so you can secure the bike without fumbling for the key. A water-resistant keyway cover helps keep grit and weather out of the barrel, and the high-visibility yellow and black body doubles as a visual warning.

Suited to riders who need a compact, everyday security item for street parking, car parks and overnight storage — ideal alongside a chain or ground anchor for layered security.

• Attack-activated alarm with motion and shock sensors
• 100dB siren

• Compact 78mm x 56mm body
• High-visibility yellow and black finish

Fit the 7mm pin through a hole in the brake disc, positioning the body clear of the caliper, fork leg and any wheel weights or ABS sensor ring.
Push the body closed to lock and arm the unit; use the key to unlock and disarm.
Always fit a reminder cable or lanyard between the lock and the handlebar so you cannot ride off with the lock in place.
Remove the lock before moving or wheeling the bike — riding away with a disc lock fitted can damage the disc, caliper and fork.
Keep the keyway cover closed whenever the lock is parked up to keep water and road grit out of the barrel.
Rinse away salt, mud and road grime after wet rides, dry the lock, then wipe the body with a soft damp cloth; avoid solvents and don't aim a pressure washer at the keyway.
Replace the lithium CR2 battery if the siren sounds weak or the unit stops arming reliably.
Remove the battery if the lock will be left unused for a long period, and store the lock somewhere dry.
Keep the spare key somewhere separate from the bike and record the key number for replacements.
For higher-risk parking, use the Screamer7 together with a chain and lock or a ground anchor rather than relying on the disc lock alone.
