- Motorbike alarm security bicycle steal lock moped
- Great product to protect your bicycle/bike
- Ultra loud 110dB alarm -- scares potential theives away
- Don't let bike thieves get the better of you – protect your investment easily and effectively with the movement triggered alarm which emits a scarily loud sound if your bike is tampered with. No thief will want to hang around when this alarm goes off!
- Traditional chains, padlocks and U Locks only do half a job and can be pretty easily removed by those who know how, but even the sight of this alarm will have even the most determined of thieves thinking twice.
- Attach to your bike, press 'B' for 2 seconds to set it and walk away safe in the knowledge that it will remain secure and protected whilst you are away.
- If your bike is moved the alarm springs into action and gives off an ear-shattering shriek for 15 seconds – and you can bet that you won't see your bike's assailant for dust!
- Protecting your bike couldn't be simpler: Attach to your bike > Go for a ride > Set the lock to 'protect mode' by pressing 'B' for 2 seconds > If your bike is tampered with the alarm will sound for 15 seconds > Return to find your bike where you left it! > To disarm the alarm enter your 4 digit code (i.e. ABCA) > Carry on cycling
- 110DB alarm – much more of a deterrent to opportunist thieves than traditional locks
- 3 sensitivity levels allow you to determine how much movement is needed to trigger the alarm
- When triggered alarm sounds 5 times. If triggered again within 5 seconds it will sound continuously for 15 seconds
- Sturdy black plastic – no metal parts to rust
- Waterproof – attach permanently to your bike without worrying about having to remove it in bad weather
- It's not just mountain and racing bikes that can be protected. Use the alarm on anything and everything that you can screw it to!
- Also for Motor bikes/Scooters and mopeds/Heavy duty garden tools such as lawn mowers and strimmers/Garden furniture
- 1 * 9V battery powered (not included)

Ownership verified by DX Loud alarm for a fair price
Posted by alexrgf on 3/14/2010
Involvement: Expert (understands the inner workings) - Ownership: more than 1 month

Price: starstarstar
Ease of Use: starstarstarstarstar
Build Quality: starstarstarstarstar
Usefulness: starstarstarstarstar
Overall Rating: starstarstarstar

Pros: Loud and easy to use alarm for a fair price. Comes with a manual in english and is very easy to install. Three adjustble sensitivity levels. Construction made is rainproof. Low power consumption (I installed mine 4 months ago and the battery still good).

Cons: Mount does not fit on thicker tubes, but it will fit in many bike models. It has no other cons.

Other Thoughts: For thicker tubes I bought the SKU 21760 but this model is much better.

Bottomline: Good value and perfect for the job. Well done DealExtreme!

Pros: Easy manual in English is included. Simple to use. Easy to install on several types of bikes. Seems to be great value for money. Waterproof. Alarms really sounds hard enough. 3 sensitivety levels. Can also be used on a recumbend bike or a velomobile.

Cons: Easy to change sensitivety but you can not see which level it's on. A little bit of trial and error solves this matter though.

Other Thoughts: I will advise my friends to try this alarm to.

Bottomline: Seems to be good value for money. First item I buy from this website but it will not be last. Service is very good.
