The new Linka Smart lock is an innovative new security system for your bicycle. Featured on Think Tank and winner of the Taipei Design and Innovation award. Now you can avoid having to open your lock on a busy street or waste time when you're in a hurry. The Linka is designed to be connected via the Linka app (Available on Google Play and App Store) to allow remote access to your lock and has a tamper alarm in case anyone is trying to steal your ride! Durable LINKA brings you reinforced security with the strength of a special 9mm hardened steel shackle, tested in extreme temperature and weather conditions. Tamper Alerts With built in sensors that detect unwanted bike movement, LINKA will trigger a screeching 110 dB siren drawing attention to the would-be thief. It will even send you a tamper alert to your phone when in range. Keyless access With LINKA Smart Bike Lock, gone are the days of looking for your keys while your hands are full. LINKA offers a truly keyless access to your bike. Automatically unlocks as you approach LINKA can detect you as you approach, and can automatically unlock within a radius of up to 2m (6ft). Phoneless Access Code Always have access to your LINKA, even when your phone battery dies. You can set, view, and change your four-digit phone-less access code through the app. Low battery reminder LINKA’s battery lasts up to 16 months. It can be charged in less than 2 hours through micro-USB. You’ll get battery low heads up notifications at 30% and 10% to ensure you'll always remember to charge. Tamper Sensitivity Adjustment Sometimes you park in a garage and sometimes in a bustling metropolis. Adjust the sensitivity of the tamper alarm and avoid false alarms.
