Power Tank
Install Any Time. Go Farther.

The Z-Force® Power Tank adds an additional 2.8 kWh of power pack storage capacity to any 2015 Zero S, Zero SR or Zero DS model. An optional accessory, the Power Tank can be added at any time during or after the motorcycle is purchased. For example, if you purchase a 2015 Zero S ZF9.4 you could actually upgrade your motorcycle to have 12.2 kWh of power pack capacity years after you purchase your motorcycle. Alternatively, if you purchase a 2015 Zero S ZF12.5 you could upgrade your motorcycle to have 15.3 kWh of power pack capacity if you had a need for additional range. With that much energy storage capacity you can expect to travel up to 185 miles in the city or 94 miles on the highway.

The Power Tank comes complete with a Z-Force® power pack module as well as additional bodywork. It is recommended that you take your motorcycle to an authorized Zero Motorcycles dealer for installation. Once installed, the new bodywork includes a completely new tank section of the motorcycle with a newly designed plastic cover. The plastic cover and additional module occupy the area where the integrated tank bag would normally sit.

Z-Force® Power Pack
More Energy. Less Space.

Z-Force® power pack technology has been revolutionizing the electric motorcycle industry since 2007 when the first Zeros started rolling out of the Santa Cruz factory. The goal: pack more energy into less space. Using state-of-the-art Lithium Ion cell chemistry and advanced battery management systems each motorcycle is able to travel farther, faster and last longer. A typical Zero S or Zero DS can travel well over 200,000 miles before hitting 80% capacity.

In addition to longevity, the Z-Force® power pack technology requires no active cooling or routine maintenance. The result is a complete electric motorcycle line that offers an exhilarating ride while saving on gas and virtually eliminating all routine powertrain maintenance.

100% Modular
Swap in. Swap out.

Zero Motorcycles is the first electric motorcycle manufacturer to feature hot-swappable modules. The Zero FX can be ridden using either one or two Z-Force® modules. A module can be added or removed in less than a minute.

Fully Recyclable

Zero Motorcycles uses the best practices in the EV industry to make sure all of our Lithium-Ion power packs are recycled. Each one uses a chemistry that allows us to take advantage of continuously improving battery-recycling programs.

Zero power packs are fully air cooled and designed to handle the most extreme conditions. Our latest generation of Z-Force® power pack technology uses new and more precise cell monitoring to ensure greater range, more power and better acceleration off the line.

Get Charged. Anywhere.

Convenience comes first. All Zero Motorcycles models are designed to charge without any additional equipment being installed in the home or garage. All that is required is a standard household outlet. Meaning, you can pretty much charge anywhere at any time. Depending on the model, each motorcycle uses between 650W – 1300W while charging (see the “Power System” section under each model for specific details).

One of the most frequently asked questions regarding electric motorcycles is “How long does it take to charge?” An often used and fun response to this question is “About five seconds.” Electric motorcycles do not fit everyone’s lifestyle. However, for many people, it will take about five seconds to plug in their motorcycle when they get home, to the office or to another frequented location. And, unlike gas stations, since these locations are not dedicated to just “filling up,” one can be working, socializing, playing or even sleeping while their motorcycle is recharging. Just like a mobile phone, riders can plug their Zero into any standard outlet. Consequently, for many individuals this means never needing to stop at the gas station or deviate from their desired route (unless drawn to a fun and twisty detour).


Zero’s scalable "quick charge" system allows owners to add-on standalone chargers that will substantially reduce charge times. Each individual charger plugs into a standard household outlet and provides roughly one additional kWh of charge to the power pack every hour. Consequently, one Quick-Charge system could more than halve the charging time of a motorcycle. Visit any motorcycle’s specs page and look under “Power System” to determine how much time a quick charge system could save you.

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.

Range 185 Miles.
Farther than it seems.
Less expensive than you expect.

One of the first questions that everyone asks about electric motorcycles is, unsurprisingly, “how far?” Zero Motorcycles offers an entire model line and each model and variation has a different range. At present, the longest range in the lineup goes to the Zero S ZF12.5 + Power Tank with 185 miles in the city. However, there are a number of options with lesser ranges that offer different benefits for those who only want a motorcycle for getting around town or the city. After all, selecting an electric motorcycle is all about making the best choice for your lifestyle.

To select the motorcycle that best meets your needs we recommend you see how far you typically ride in a day. Depending on how closely you watch your mileage the answer may surprise you. According to the US Department of Transportation, the average ‘driver’ travels about 13,476 miles per year. That breaks down to roughly 37 miles on average per day. Once you own a Zero, 37 miles will cost you a whopping 37¢ per day. Did we mention that there’s also no routine powertrain maintenance?

Get Modular.
Or… charge on the fly.

Range is fundamentally dependent on the amount of kilowatt-hours (kWh) in the motorcycle’s power system. As you charge you increase the kWh in the power pack and, once fully charged, can achieve the maximum range of your motorcycle. As you ride electric you’ll find that every time you stop can be an opportunity to top up and go a bit farther. Zero offers several systems to quickly increase the potential range of each motorcycle.

Add a second module:

The Zero FX uses modular power packs that allow you to add a second module to your power system that effectively doubles your potential range. You can also swap a discharged power pack for a fresh one in about sixty seconds.

Use a quick-charger:

Zero offers a quick charge system that cuts the charge times by as much as 75%.

The Four Factors
Maximize your Range

Range varies in electric motorcycles similarly to how it varies in gas motorcycles. However, the big difference between electric and gas is that energy consumption is averaged over a shorter distance on an electric motorcycle. Electric motorcycles are designed for convenient daily recharges versus less frequent and less convenient trips to the gas station. As a result, the same electric motorcycle often yields different ranges from one full recharge to the next.

How to Predict the Range

To generally predict how an electric motorcycle’s range will be affected, you can use the four factors:

  • route
  • rider
  • weather
  • motorcycle

By considering each of these factors, you can use specifications such as ‘city range’ as standards to estimate what the motorcycle’s real world range will be under the your particular usage case.

Ownership Advantage
Exhilarating performance. Carefree ownership.

There are some clear advantages to going electric: no need to visit the gas station, no oil, no exhaust, etc. In addition, there are a host of benefits experienced by Zero owners on a regular basis that are not as obvious. Behind the design of each cutting edge model is a philosophy of elegant simplicity that keeps the weight of the motorcycle low, virtually eliminates all routine powertrain maintenance and yields stealthy acceleration. The result is an incredibly exhilarating ride and an ownership experience that appreciates mile after mile.


As a premium brand, Zero designs each motorcycle with the sort of quality and integrity that inspires an exceptional riding experience. Beyond that, the upfront cost of a Zero is not what it appears to be when compared against its traditional internal combustion counterparts. Each mile ridden on a Zero is considerably less expensive, making it considerably more enjoyable, due to the elimination of routine powertrain maintenance and no gas expenses. As it turns out, when compared to other premium brands, a Zero starts saving the owner money on gas and maintenance from day one. In fact, over the life of their motorcycle many Zero owners actually save more than they would have if they had purchased a comparable internal combustion model.



All Zero motorcycles feature a direct drive, maintenance-free powertrain. As an incredibly efficient system, direct drive channels power directly from the motor to the rear wheel via a strong and silent, constant tension belt. Not only does direct drive minimize friction loss by eliminating clutches and gears, but it also helps eliminate the need for routine powertrain maintenance and reduces the weight of the motorcycle.

The Z-Force® powertrain uses revolutionary technology to maximize efficiency and eliminate the need for complex cooling mechanisms. The resulting system produces so little heat under typical operation, that everything from the power pack to the motor itself is entirely air-cooled. The result is fewer possible mechanical problems and increased range. When it comes to maintenance, parts, fluids, transmissions and heat, less is more.

Top 15 Things You’ll Never Do Again

Clean. And getting Cleaner Every Year.

Zero Motorcycles’ 100% electric powertrain significantly reduces CO2 and noxious fumes emissions while also saving oil reserves. Regardless of any one personal or political reason, conserving oil and reducing tail pipe emissions offer a wide range of benefits. In fact, because the electrical grid is becoming increasingly efficient year after year, a Zero will become more energy efficient and cleaner with age. And for those who truly aspire to absolute energy independence or eliminating emissions, it is even possible to power a Zero using completely renewable energy sources. Regardless of where the energy comes from, there’s something very freeing about passing the gas station as the prices continue to hit new highs.

Fewer Emissions
