Myers Motors has introduced its NmG (No More Gas) personal electric vehicle: a sealed lead-acid battery-powered tricycle with a top speed of 70 mph and a range of 20–40 miles.

The NMG is a direct descendant of the Corbin Sparrow, which was made at the Corbin plant from 2000 until late 2002. In March 2003 Corbin Motors filed for bankruptcy; Myers Motors resurrected the company in 2004, and completely re-engineered the entire transport system, electronics, and charging systems, while retaining the distinctive body of the Sparrow.

The NmG uses a 156V 20 kW (30 kW peak) DC Motor to drive the single rear wheel. Thirteen sealed lead-acid Optima batteries provide the power. Six are located under the front hood and the remaining 7 are under the drivers seat. The batteries recharge in four to six hours at a 110-volt, 20-amp outlet, or two to three hours at a 220-volt, 20-amp outlet. A 110-volt charger will recharge the batteries in six to eight hours.

The Optima batteries are absorption glass mat (AGM) lead-acid batteries in which the acid is absorbed by a very fine fiberglass mat between the plates and immobilized. No silica gel is necessary. With the acid absorbed and available to the plates, the glass mats allow for a fast reaction between acid and plate material.

The AGM battery has low internal electrical resistance. This, combined with faster acid migration, allows the AGM batteries to deliver and absorb higher rates of amperage than other sealed batteries during discharging and charging. In addition, AGM technology batteries can be charged at normal lead-acid regulated charging voltages and it is not necessary to recalibrate charging systems or purchase special chargers.

The three-wheeler is considered a motorcycle for the purposes of registration, insurance and parking.

The NmG offer cabin features such as power windows, AM/FM stereo and CD player, power ports for laptop and cell phone and a fan-operated heater/defroster. The trunk offers six cubic feet of storage.
