City The city range is derived from the U.S. Environmental Protection Agency's (EPA) Universal Dynamometer Driving Schedule (UDDS) which is a standardized test that is used to provide emissions and fuel efficiency data to consumers. The resulting labeling is posted on most ‘for sale’ gasoline vehicles and allows consumers to judge the fuel efficiency of competitive vehicles on an equal plane. Now adopted by the Motorcycle Industry Council (MIC), and named “City Driving Range Test Procedure for Electric Motorcycles", Zero Motorcycles uses this newly adopted standard with the hope that other manufacturers will follow suit. For electric motorcycles, this provides interested buyers with standardized information to compare the range of one motorcycle against another. |

» Combined In order to give our customers additional range information, Zero collaborated diligently with the Motorcycle Industry Council on the development of a new "Highway range" test and reporting standard for electric motorcycles. This new standard is meant to provide a range value riders can expect to achieve when using the motorcycle for highway commuting. It is based on an extensive 3rd party research which concluded that, when coupled with the distance traveled on city roads getting to and from the highway, as well as the distance spent in highway congestion, the average "highway commute" is made up of 50% steady-state high speed riding and 50% city-like riding. The steady-state high speed used in this test and reporting standard is 55 mph. The Formula: |

Max capacity Maximum capacity tends to be the electric vehicle industry’s choice for reporting the maximum amount of energy that can be stored in a vehicle’s power pack. About kWh : Where gasoline vehicles use gallons, electric vehicles frequently use kilowatt hours (kWh) to measure the total possible ‘fuel’ or energy storage capacity. The Formula: |
8.5 kWh | 11.4 kWh | 14.2 kWh |
Nominal capacity Nominal capacity is the most accurate measure of the amount of usable energy that can be stored in a vehicle’s power pack. It differs from maximum capacity because it is calculated using an average voltage that is more often ‘the norm’ rather than a maximum which is rarely seen.

Quick 2x charger time (accessory) Zero's scalable "quick charge" accessory offerings allow customers to acquire as many as three standalone chargers (in addition to the existing on-board unit) for up to a ~75% reduction in charge time depending on the model and year. Please keep in mind that most household electricity circuits are rated to 110V/15A, which can only support a single charger. As a result, in order to make use of Zero's quick-charge accessories, you must plug each charger into a separate 110V/15A circuit. If connecting to any other, higher-rated household circuit, you must make sure it can safely support the load of each of Zero's 1,200W input chargers. |

Equivalent fuel economy (city) Electric vehicle fuel economy is measured in Miles Per Gallon equivalent (MPGe) which indicates, via an Environmental Protection Agency (EPA) prescribed formula, how far an electric vehicle can go using the same amount of energy as is contained in one gallon of gasoline. Electric vehicles are much more efficient than their internal combustion engine (ICE) counterparts. An electric vehicle powertrain can turn above 90% of the energy supplied to it into usable motive power. An ICE powertrain can only turn about 25-30% of its supplied energy into motive power. The result is that an electric vehicle powertrain can operate at over three times the efficiency of its ICE counterparts. The Formula: Equivalent Fuel Economy, Highway = (Highway range) / (Power Pack nominal capacity) x 33.7 (EPA kWh per gallon of gasoline) |
