The Lightning Motorcycle Electric Superbike seems to collect records as easily as falling off a log. It holds the current world records for fastest production motorcycle (189.086 mph / 304.304 km/h), and in a tweaked version for fastest electric motorcycle (215.960 mph / 374.554 km/h). While setting this latter record, the equivalent fuel mileage was still better than 50 mpg. Now it also holds the record for fastest ascent of Pikes Peak by an electric motorcycle. More importantly, it is the first electric motorcycle to win over a field of gas-powered motorcycles.
Carlin Dunne, who rode the Superbike to two-wheel victory at Pikes Peak this year, is no stranger to records himself. He has now won the Pikes Peak climb three years in a row, and owns the all-time record of nine minutes and 52.819 seconds for his performance in 2012 on a Ducati Multistrada 1200.

Of course, the Pikes Peak Climb is ideally suited to electric bikes. It takes place at altitudes that make regular gasoline engines cough and wheeze. But as the twists and turns of the course are a bit more difficult on a bike with a battery pack weighing about 250 pounds (110 kg), what the Superbike wins in the straights might be lost in the roundabouts. But not this year.
The Electric Superbike boasts an amazing set of specs. The motor is an internal permanent magnet Remy HVH250, an oil-cooled electric topping out at 10,000 rpm that pumps out in excess of 125 hp (92 kW). The exact value isn't specified, and the HVH250 can put out 230 hp (170 kW) at higher voltage than used in the Superbike. The basic Superbike comes with a lithium-ion battery pack that holds 12 kWh of energy at 370 volts, but a larger pack can be chosen. The total weight of the bike is just under 500 pounds.
Lightning claims 0 - 100 mph (160 km/h) time of 3 seconds, and acceleration from 100 mph to top speed (166 mph for the basic Superbike) in less than ten seconds.

The Superbike uses a monocoque design by Glenn Kerr, wherein the battery pack and motor serve a dual function as the primary stressed elements of the chassis, a design whose equivalent appears in most large gas-powered bikes. The swingarm of the Superbike is directly connected to the rear of the motor.
Lightning's Superbike is equipped with user-programmable regenerative braking, allowing the batteries to be charged whenever the throttle is closed and the brakes applied. The effect on the ride is said to closely replicate the engine braking effect characteristic of gas-powered bikes. The programming allows the user to balance the braking between maximum range and driving style.
