Range
City (EPA UDDS)
The U.S. Environmental Protection Agency's (EPA) Universal Dynamometer Driving Schedule (UDDS) 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.
42 miles (68 km)
Highway (commuting, 55mph)

For 2012, 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. For Zero's higher top-speed S and DS models, the steady-state high speed used in this test and reporting standard is 70 mph. For Zero's lower top-speed XU, this speed is 55 mph.

The Formula:
S and DS 70 mph Highway Commuting Range = 1 / [0.5/(70 mph steady-state range) + 0.5/(EPA UDDS range)]
XU 55 mph Highway Commuting Range = 1 / [0.5/(55 mph steady-state range) + 0.5/(EPA UDDS range)]

TypeHigh efficiency, axial flux permanent magnet, brushless motor with integrated forced air cooling
Controller
An electric motorcycle's controller is akin to a gas bike's fuel injection system. It precisely "meters" the flow of electricity from the battery to the motor according to the action of the rider's throttle and surrounding conditions, via a sophisticated map algorithm.
High efficiency, 220 amp, 3-phase brushless controller with re-generative deceleration
Top speed (max)
The max top speed is based on the results of government regulated standardized testing known as homologation. Actual max top speed may vary according to riding conditions and the battery's state-of-charge, and can be sustained for a limited duration.
65 mph (105 km/h)
Top speed (sustained)
The sustained top speed is that which the motorcycle can be expected to hold for an extended period of time. This sustained top speed may vary according to riding conditions.
55 mph (88 km/h)

Maximum 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:
Maximum kWh = (# of cells) * (cell Amp-hour capacity rating) * (cell max voltage rating)

3.0 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.

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:
Nominal kWh = (# of cells) * (cell Amp-hour capacity rating) * (cell nominal voltage rating)

2.6 kWh
Estimated pack life to 80% (city)

This represents the expected life of the power pack, to 80% of its original capacity, when the motorcycle is ridden according to the EPA's "city" UDDS duty cycle. An electric motorcycle can continue to function perfectly normal with a power pack that has lost over 20% of its original capacity. The only certain change will be a reduction in maximum range.

The Formula:
Estimated pack life (miles / km) = (EPA UDDS range) * (cycle-life rating of the battery) * (90%, to account for 20% linear capacity loss over this rated life)

Charger type1kW, integrated
Charge time (standard)3.1 hours (100% charged) / 2.7 hours (95% charged)
Quick 2x charger time (accessory)

Zero's scalable "quick charge" accessory offerings for 2012 allow Zero S and Zero DS 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. Zero XU, Zero X and Zero MX customers can choose to add one more standalone charger for a ~50% charge-time reduction. In technical terms, the Zero S and Zero DS have two charge circuits, whereas the Zero XU, Zero X and Zero MX have one, and up to two chargers are allowed in each circuit. For the Zero S and Zero DS, the first "2x" quick-charge accessory adds a charger that plugs into its second charge circuit (the onboard charger is plugged into the first). Additional Zero S and Zero DS charge accessory options (3x and 4x), as well as the single Zero X/Zero MX option, use a “Y” adaptor that allows up to two chargers to plug into a single circuit.

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.

Typical cost to charge

This indicates the average cost to recharge a fully drained power pack. More often, riders will be charging a partially drained power pack and will have a lower cost of recharge. The actual cost of recharging will always be dictated by the amount of charge put into the power pack and the cost of electricity flowing from the particular outlet.

The Formula:
Typical Cost to Recharge = (US average consumer cost per KWh) X (Power Pack nominal capacity)

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, City = (EPA UDDS range) / (Power Pack nominal capacity) x 33.7 (EPA kWh per gallon of gasoline)

Equivalent Fuel Economy, Highway = (Highway range) / (Power Pack nominal capacity) x 33.7 (EPA kWh per gallon of gasoline)
