Zero Motorcycles Inc. is an American manufacturer of electric motorcycles. Formerly called Electricross, it was started in 2006 by Neal Saiki, a former NASA engineer, in Santa Cruz, California. The company is now located nearby in Scotts Valley.
The Zero S began shipping in volume in 2010, the first model year to include the Agni Motor, at which time the DS, a dual-sport model based on the S chassis became available. The XU, a smaller street bike with a removable battery, based on the same chassis as the Zero dirtbikes was produced from 2011 to 2013.
In 2012, Zero introduced the ZF9 Power Pack with the Zero S & DS models making them the first production electric motorcycles that can exceed an EPA-estimated 100 miles on a single charge.
In 2013 the Zero S and DS were completely redesigned. The battery capacity was increased to 11.4kWh, and a new brushless permanent magnet AC motor was introduced. In 2013 the Zero FX dual-sport model with modular removable power packs was introduced. CHAdeMO fast charging was also available on 2013 models.
In 2014 the optional 2.8kWh "Power Tank" became available. 2014 also saw the addition of the Zero SR to the range, a higher performance version of the Zero S, incorporating more powerful controller electrics and a motor with higher temperature magnets.
The 2015 models had battery pack size increased to 12.5kWh, for a total possible maximum capacity of 15.3kWh including the optional Power Tank. Also introduced in 2015 were standard ABS brakes and Showa suspension. CHAdeMO fast charging was eliminated as an option, leaving instead an optional quick charger accessory at added cost.
Zero Motorcycles also produces a line of electric motorcycles for police, authority, and military use. The fleet motorcycles are based upon the company’s standard models but outfitted with equipment such as police lights, sirens, crash bars, and storage accessories.
Zero's Lithium-ion power packs and motors were developed in-house, and are branded under the names "Z-Force" and "ZF". The power pack uses a cell configuration that operates at 102 volts. The motorcycles' propulsion is provided by a single electric, air-cooled, brushless, permanent-magnet 3-phase AC motor. The motor is directly coupled to the rear wheel by a belt or - optionally on the Zero FX - a chain. A controller manages the power delivery and comes in 420-amp and a 660-amp sizes depending on the model.
Zero Motorcycles has had success racing at Pikes Peak. In 2012 a Zero FX was the first production electric motorcycle to break the 12 minute mark. Zero has also won the production electric motorcycle class in 2013, 2014, and 2015.
Zero's main competitor is the Victory Empulse (formerly Brammo), but current and upcoming models from Lightning, Energica, Alta, and Mission will compete with Zero's product lineup as well. Some of the larger OEMs have also released electric concepts and prototypes such as the Harley-Davidson LiveWire electric concept, and Yamaha's PES1 and PED1.
Zero Motorcycles have the same inherent advantages and disadvantages as most electric vehicles, but in particular have been criticized for lack of range and slow charging capabilities - which make long-distance touring use difficult compared to their combustion engine counterparts. Detractors also point out a comparatively high price compared to equivalent conventional motorcycles.
