Michael Czysz said in an interview on the history of this electric motorcycle:[2]
"In less than five months we took a suggestion and turned it into a motorcycle. "A motorcycle that is unlike anything I have ever ridden. No gas, no oil, no clutch, no need to even warm up the engine – no engine. "Gone is the age-old ritual of rhythmical throttle blips that can audible seduce a motorcyclist into a pre-ride trance – now your bike waits for you. Enter what may be the next big thing in motorcycles; invisible, nearly silent and magically linear power."
As of August 2010[update], the MotoCzysz team for the TTXGP is listed on the eGrandPrix website as:[3]

The MotoCzysz E1pc is described as having "10 times the battery capacity of a Toyota Prius and 2.5 times the torque of a Ducati 1198 [in] a package that looks like something out of a 24th-century Thunderdome."[4] The E1pc is powered by "10 individual lithium polymer cells that each weigh 19.5 Lbs 12.5 kWh" and operates close to the maximum allowable 500 volts system. The motive force is provided by a "DC internal permanent magnet motor [called] 'D1g1tal Dr1ve' [and is] small enough to hide within the swingarm beneath the rear shock." The motor is oil-cooled developing 100 HP and 250 Lb-Ft of torque, continuously.[4]
On June 10, 2010, US racer Mark Miller won the TT Zero race on a 37.773 mile mountain course riding a redesigned E1pc[4] with a time of 23 minutes 22.89 seconds and an average speed of 96.820 mph.[1] Beyond the electric motorcycle technical accomplishment, this is "the first time an American-made bike has won a race at the Isle of Man since Indian debuted a two-speed gearbox in 1911 and only the second time an American rider has finished first there."[1]
The previous year, in June 2009, Mark Miller rode an earlier design of the bike[5] on the 37.733-mile (60.725 km) course of the TTXGP on the Isle of Man.[6] The 2009-model Motoczysz E1pc did not finish the race.[7]
