I think Wendax is correct regarding the name Taser by Trident Tricars, however I have located an online reference that may shed a bit more light on the subject. Trident Tricars Inc. (USA) is a wholly owned entity of Asian Dragon International Corporation, which is based in the Philippines, and whose founder, President, and CEO is Mr. Robert Sullivan, an Australian who was (is?) residing in the Philippines. According to the website (dated June 2011), the Taser was a new design which was radically different than the other Trident models (a single rear wheel rather than a single front wheel) being offered at that time. Whether the Taser, or any other Trident designs are currently available is unknown to me.
