Two Electrocity prototypes were initially built in 2002; one based on DAF SB120 chassis, the other based on a Dennis Dart SLF chassis. The bodywork design was similar to the existing Wright Cadet and Crusader, which were also built on DAF SB120 and Dennis Dart SLF chassis respectively, with the addition of battery pods on the roof of the Electrocity being the main difference. The Electrocity was the first bus of its kind to be built, and the prototypes competed mainly with the TransBus Enviro200H.
