Zero-X Electric Motorcycle

Check out the Zero-X off-road electric motorcycle, made by Zero Motorcycles, Inc. of Santa Cruz, California. The Zero-X is a 100% electric off-road motorcycle powered by a 17kW motor capable of 23 peak horsepower. That’s about equivalent to a 250cc gas motorcycle, and it’s not bad at all for an electric vehicle that weighs a meager 140 pounds. The light weight of the motorcycle itself is due to an innovative mix of motorcycle and modified bicycle parts and to an aircraft aluminum frame that weighs 18 pounds.

The Zero-X battery pack weighs 40 pounds - almost a third of it’s total weight.

Zero-X controls include a front a rear brake and a twist throttle.

The Zero-X is quick - it can accelerate from 0-30 mph in under 2 seconds, with a top speed of about 60 mph. The ZERO X Speed controller features the ability to customize both the speed and acceleration of the motorcycle. With a flip of the switch you can limit the top speed to a “motorized bicycle” legal 30mph. Another switch sets the acceleration from the beginner-friendly “easy” mode to an unrestricted “sport” mode that gives you full power and full acceleration. With the electric motor giving you full torque at 0 rpm, popping wheelies is not a problem. And, since it’s totally quiet, you can ride this dirt bike in places you would not normally be able to due to noise restrictions.

Here’s the rear hydraulic disc brake assembly.

The drive chain uses an unusual 3/8-inch pitch.

The motor of the Zero-X is powered by a lithium-ion array capable of giving you between 1.5 to 2 hours of riding per charge. The batteries can be recharged in about 2 hours by using a provided fast battery charger that plugs into a standard wall outlet. The batteries weigh about 40 pounds, and their lifetime is expected to be between five and six years with average use. Although the batteries are expensive to replace - $2,950 - they only cost about $0.25 per recharge.

The Zero-X electric motorcycle retails for about $7,500 plus $300 shipping and provides an interesting electric option for those looking for a green alternative off-road vehicle. Take a look at this excellent Zero-X Motorcycle First Look, or visit
