In Spring 2014, ETS unveiled a full electric bus for a four-month pilot program through October 2014. The buses were referred to as "ETS Stealth Buses" and were on lease from Build Your Dreams (BYD) Co. Ltd.. The buses did not have a fare box, but instead were accepting customer surveys about electric buses as fare. Even without fare capacity the buses were placed on several different routes around the city to give many Edmontonians the ability to experience the new exhaust-less bus. These test buses were not winterized.
