Italian company ULOCK are very well-known for their bike locks, and now they have released a keyless smart lock that requires only one tap on your smartphone to lock and unlock, thanks to Bluetooth 4.0 LE communication. In proximity mode, it will automatically lock itself when the user (and their phone) moves more than 3 metres away and unlock once they come back into range. There is even a built-in geolocation feature that lets you know on your map the location of your locked bike.

ULOCK is made of galvanized C40 steel, heat-treated to resist cuts, drills, the strongest hits and also the sneaky attack of rust, completely covered in a protective silicon platinic rubber to protect your bike from scratches. It also features a high security sphere-locking mechanism activated through a Bluetooth 4.0 Low Energy encrypted connection, powered by a special battery granted for 25.000 lock/unlock movements and an average lifetime of 5 years.
