What makes a ZEV, a ZEV?
"- ZEV has been quietly building high quality electric scooters for more than a decade now, including the fastest and longest range electric scoots in the world---that frankly put the rest of the industry to shame." NEWATLAS Jan 2017
ZEV are designed by highly skilled aircraft and race vehicle engineers and assembled by aircraft mechanics. They are tested on airport test tracks and on race tracks where they can be pressed to find any limits. Then they are run over the rough mountain roads of West Virginia, USA to ensure durability. They are driven daily by customers around the world as their "go to work vehicle"
ZEV BIKE DESIGN FEATURES:
-We are the world's most efficient highway motor vehicles with MpgE of 636 at 55 mph, and 1270 at 35 mph. This is all due to the following:
-ZEV does not use the SAE J2982 dynometer method of estimating range as do some competitors. ZEV uses actual on the road testing to obtain real world range results that a customer can duplicate. Flat East Coast roads such as the 141 miles between Ocean City, Md and Norfolk, Va on US-13-S (55 mph testing) or sections of Southern coastal I-95 are used along with shorter sections found to be flat in other areas.
-HUB MOTORS, also called wheel motors, that put the motor in the rear wheel to eliminate chains and belts and free up chassis space for more battery capacity. Power to 30 KW continuous in single stator motors (to 50 kw in testing). These are the highest efficiency motors available.
has an all aluminum hub motor and wheel (competitor wheels are
generally steel and none have the internal and external cooling fins
nor the one piece rim and motor housing). The advantage is not just the
lighter weight and better ride, but the far greater heat conduction of
the aluminum to remove heat from the hub motor. The steel wheeled
motors of competitors are plagued with heat problems resulting in
magnets coming loose in the housings. The competitors also cannot hold
full rated power continuously due to heat issues.
These factors help make the ZEV motors the highest efficiency motors available. To put that in prospective, (1) We run more range with our LRC than the ZERO SR which has a much larger battery. At the 2016 Ohio Vetter Challenge the stock ZEV LRC ran less watts per mile power use than two ZERO based streamliners in the competition (which each had larger battery packages), beaten only by 3% by a purpose built streamliner. (2) On the race track, in purpose built efficiency cars, teams using the power train from the ZEV LRC state "The fact we are using only 70% of our allowed power and crushing the competition tells me we are on the right track. We were the best on the track lapping everyone". T Nusbickel, CHS
-USA ELECTRONICS COMPONENTS. Especially all of the critical MOSFET in the controllers of all cycle and scooter over 3600 watts are USA made power transistors for maximum reliability.
-VERY HIGH MOSFET COUNT to prevent controller overheating and shutdown. Our standard controller of 3600 watts and up have 36 USA made high power/amp Mosfet rated at 150 v/225 amp. Hot transistors do not live as long as cooler running ones. More Mosfet mean less on time per Mosfet and less heat to the components for the longest life (and not shutting down in the middle of a hill).
-OIL COOLED AND LUBRICATED MOTORS cool the motors and disperse heat from hot spots, keep the rust out off of the iron core and magnets, and lubricate for longer life. No ZEV motor has ever failed. Our motors consistently run up to 100 degrees C lower temperatures than others in matched conditions and rarely more than 25 degrees over ambient temperatures.
-DOUBLE SET OF HALL SENSORS are in all of the 13 and larger inch motors for long life. If and when the first set ever go bad, the second set is prewired and ready to go.
-EVERY BIKE IS ROAD TESTED MULTIPLE TIMES before shipping and charged multiple times. We are the only company in the world that test drives each and every bike multiple times before shipping.
-UNUSUALLY LONG SWING ARMS that allow the pivot point to be under the rider's seat to smooth out the ride and follow the road better. Ride and handling are significantly improved.
-MORE RAKE, TRAIL, AND WHEELBASE than any other brand of motor scooter for radically better handling at speed.
-Black center wheels with polished rims front and rear matching the new, black, Gen IV modular motor. Everyone else just paints the rims over to save money.
-HIGH SPEED, HIGH LOAD, MAXIMUM SAFTY MARGIN TIRES rated for 150 kmh / 94 mph and with test speeds of 150 mph / 241 km/h in the 13 inch motor scooter wheels. These give the maximum possible safety and handling in keeping with the speeds of the new bikes on all models in power over 3600 watts in all 13 inch rim bikes. The load capacity is also an outstanding 60 tire load index for 531 lbs / 250 kg of load capacity. We believe you should run the best tires you can find. These tires are also why are braking distances are so good compared to others. These tires also add to the range of the bike with low rolling resistance.
-EXCEPTIONALLY HIGH BATTERY CAPACITY. No other electric motor scooter company in the world has a model that can hold over 12 Kwh like a ZEV.
-RARE EARTH MOTOR MAGNETS ARE neodymium-iron-boron magnets.
-RIGID CHASSIS. All ZEV bikes use a aircraft construction style, steel tube frame where the battery box acts as a structural frame member for extra stiffness.
-Every ZEV motor scooter or motorcycle comes with a side and a center stand. Most of the extremely expensive bikes like a ZERO do not have a center stand.
-HIGH END GAS SHOCK suspension standard on all bikes over 3600 watts.
-BMS (battery management system) is built into the bike to keep track of the cells charge and discharge.
-BATTERY PACK DESIGNED to allow repair. ZEV does not use a single monolithic battery pack like virtually every competitor. We use battery modules to that if a cell goes bad, you can remove only that module and put a new module in.
-BATTERY CHARGERS all fit into the under seat luggage box with room to spare. Take the charger with you for your longest trips
-Different controller and motor options to best match your driving style and needs from range to maximum acceleration.
This is why we are the world's most efficient road vehicle. Nobody else even comes close with a car or a bike. With 140 mile range at 55 mph, that is 636 MpgE even on the large LRC (and more on the more streamlined M-S motorcycle models. While our 140 mile on a charge was under dead flat coastal road conditions, we have customers reporting 124 miles achieved in actual daily commuting conditions.
Go a little more slowly, and customers report to 206 mile range on the LRC driving along coastal flat roads on the 10 kwh battery pack.
Standard Equipment on All Scooters
- Center and side stand
- Waterproof controller and motor
- Waterproof electrical connections
- Quick change wiring connections to all major components.
- Exceptionally bright tail and stop lights.
- Dual headlights
- LED Daytime "Always on" running light as required by law.

- Running lights and turns signals
All ZEV bikes feature dual headlights and tail lights for maximum brightness and visibility. A "Always On" running light alerts drivers to your approach.
All ZEV bikes use a minimum of dual front piston brakes and dual rear piston brakes for maximum braking.
Part of the big power advantage in ZEV bikes comes from the cooling of the controller and the motor. The controller is heavily finned to dissipate heat. The higher the power of the bike, the more fins and cooling. This photo is of the lowest power controller with the least amount of cooling fins.
Large under the seat storage area on most models.
All available space is stuffed with battery for maximum range and power. All ZEV bikes under 7100 watts and even the big LRC hold the batteries in a low mount row to lower the CG and make the frame more rigid. (competitors with smaller chassis frames must stack the batteries in a second high row even for 5000 watts).
The lower the bike CG, the better it performs in hard stops as it does not want to lift the rear wheel and more rear brake can be applied. This also helps to yield a light feeling bike that can be flicked from side to side through the turns.
