Great locking system for your bike. My personal review below :

Pros :

• There's no need to worry for locks when you are using your bike since it s now attached into your bike with a much lesser weight than ordinary locks.
• It does not need any keys anymore instead you can set them either in the locking system where you can set some protective codes in it or you can control them with the use of your smartphones.
• It will help you notify if there is unusual thing happen to your bike into your smartphone.
• It's application is downloadable on App Store and Google Play

Cons :

• A good safety tool for bikes. I don't see any other cons except that it is expensive.
