Multiple Isle of Man TT winners John McGuinness and Bruce Anstey will again represent Team Mugen in the SES TT Zero class in 2015.
Despite a wrist injury, McGuinness completed the one-lap sprint at an average speed of 117.366mph in 2014 to win the race in a new record time.
He will be joined by Anstey, who holds the outright TT lap record at 132.298mph and has won nine TT races.
The 2015 race will be held on Wednesday, 10 June.
The duo are the only riders to break the 20-minute barrier on an electric bike on the TT course.
