Linka is a smart, keyless bicycle lock. If someone fiddles with your Linka lock, an alarm goes off and you will receive an alert via your phone. And on top of that, the Linka locks the wheel to the frame of the bicycle, so the would-be thief can’t ride away on your bike. The inventor of Linka, mechanical engineer Mohamed Mohamed from Emeryville, California, pitched his business on Shark Tank in February 2016. Alas, Mohamed didn’t get a deal on the show but he continues to expand the Linka line of bike locks working the most modern technology available.
Coming soon is the Linka Leo, which comes with GPS tracking. So if a thief picks up the bike and puts it in a car, the Linka Leo can track the stolen bike and pinpoint its location with a 3m range of accuracy. The Linka Leo has a built-in battery that lasts up to 2.5 years and can be charged in less than three hours. New episodes of Shark Tank (Season 10, Fall 2018) air Sunday nights on ABC.
