There is nothing worse than cycling somewhere only to find there is nowhere to secure your bike. However, the Linka Smart Bike Lock ($99) gives you an instant and safe solution for keeping your bike safe. A frame-mounted lock that works as a self contained unit with a 9mm hardened square steel ring which can be locked at a push of a button. Plus the built-in 100 dB siren will go off should anyone decide to try and pick your bike up. On your return the Smart Lock picks up the signal from your phone and unlocks the bike for you. But don’t worry should you leave your phone at home there is a four digit code that will release your bike instead. As you can see, it’s called the Smart Bike Lock for a reason!
