9.4 kWh  12.5 kWh  15.3 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.

Charge time (standard) Typical charge time using the motorcycle's onboard charger and a standard 110 V or 220 V outlet. Note that charge times to 95% are referenced for two reasons. First, with normal use, it’s rare that a power pack would be discharged to 0%. Second, "topping off" from 95% to 100% takes 30 minutes, regardless of charging method, in order to maximize battery capacity.

» With one accessory charger Zero's scalable charging accessories allow customers to add multiple standalone chargers (in addition to the existing onboard unit) for up to a ~75% reduction in charge time, depending on the model and year. Zero Motorcycles generally recommends that only one charger be plugged into one circuit, including the motorcycle's onboard charger. Plugging multiple chargers into a single circuit risks drawing too much power, thereby activating the source's circuit breaker. Some household circuits—including many in Europe—operate at high enough capacities to power multiple chargers. It is the customer's responsibility to first verify that any given power source is rated at high enough output to safely support the load of a charger or 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 2530% 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)

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.

Est. 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.

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: 
2.8 kWh  5.7 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:

Charge time (standard) Typical charge time using the motorcycle's onboard charger and a standard 110 V or 220 V outlet. Note that charge times to 95% are referenced for two reasons. First, with normal use, it’s rare that a power pack would be discharged to 0%. Second, "topping off" from 95% to 100% takes 30 minutes, regardless of charging method, in order to maximize battery capacity.

» With one accessory charger Zero's scalable charging accessories allow customers to add multiple standalone chargers (in addition to the existing onboard unit) for up to a ~75% reduction in charge time, depending on the model and year. Zero Motorcycles generally recommends that only one charger be plugged into one circuit, including the motorcycle's onboard charger. Plugging multiple chargers into a single circuit risks drawing too much power, thereby activating the source's circuit breaker. Some household circuits—including many in Europe—operate at high enough capacities to power multiple chargers. It is the customer's responsibility to first verify that any given power source is rated at high enough output to safely support the load of a charger or chargers. Zero motorcycles' onboard chargers draw up to 1500W (Zero SP, DSP) or 800W (Zero FXP). Offboard accessory chargers draw up to 1200W.

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 2530% 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)

Typical cost to recharge 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:
