The Performance and Value Leader In Electric Vehicles!

What makes a ZEV, a ZEV?

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 to ensure durability. They are driven daily by customers around the world as their "go to work vehicle"


ZEV bikes are "engineered" bikes, not accounting or finance driven.  We put our development money in performance and reliability first and foremost.  

ZEV BIKE DESIGN FEATURES:

-HUB 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 15 Kw continuous in single stator motors, to 20 Kw continuous in two stator motors.  The highest efficiency motors available.

           ZEV 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. 

-USA ELECTRONICS COMPONENTS.  Especially all of the critical MOSFET in the controllers of all 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 24 USA made high power/amp Mosfet rated at 150 v/225 amp.  Our bikes of 12 Kw and up have 36 of these Mosfet.  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. 

-DOUBLE SET OF HALL SENSORS are in all of the 13 inch motors for long life.  If and when the first set ever go bad, the second set is prewired and ready to go.

-DUAL STATOR MOTORS are in several models for the maximum power output at a given weight and allowing two controllers to run at the same time.  There is always a backup controller.  The heat is better dispersed. The power output is higher than a single stator. The efficiency is greater.

-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 before shipping. 

-UNUSUALLY LONG SWINGARMS 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 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 10 Kwh like a ZEV.  

-RARE EARTH MOTOR MAGNETS ARE neodymium-iron-boron magnets.



-RIGID CHASSIS All ZEV bikes use a aircraft construction style, thick wall steel tube frame where the battery box acts as a structural frame member for extra stiffness.  

-LARGER BRAKES than any competitor in the weight class.  

-HIGH END GAS SHOCK suspension standard on all bikes over 3600 watts.

-BMS (battery management system) is built into the bike.  We use the same style system as the BMW i3 where there is a circuit board on each battery module that is daisy chained to the controller 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.  This is also the same concept as the BMW i3.

-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.



-EVERY BIKE MODEL IS TESTED TO WEIGHT BEYOND ITS RATING by sandbag loading.



Lots of company brag about the energy efficiency of their motors.  But the potential for saving energy is far greater than that factor.  An energy efficient motor can only save 10% over another design at constant load.  But electronic speed controllers like the ZEV three speed can reduce energy 30% (even before it goes into sine wave clipping mode that other controllers cannot do).  Optimizing the mechanical systems can save another 60%. Consider where the torque bulge is and how large is it.   A low rpm torque monster like a ZEV motor has little or no torque lag response to throttle. A higher rpm motor running through belts or chains or even direct, lags the throttle causing a lot of wasted amps. Every second of rolled on throttle and little or no jump in rpm and vehicle speed means wasted energy.  Consider the heat shedding ability of the motor and controller.  Every bit of heat makes the parts run more inefficiently. A ZEV, we dwell on the minutia of every factor affecting the performance of our systems.

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
  • Daytime "Always on" running light as required by law.
  • Large under the seat storage area on all models above 3600 watts(except for S8500 LR and T series models)
  • Speedometer in Mph and or Kilometers with Odometer
  • Battery Power Remaining and Available Gauge
  • Battery Charger
  • Luggage Rack
  • Mirrors
  • Anti-theft Lock
  • Running lights and turns signals 

All ZEV bikes feature dual headlights and tail lights for maximum brightness and visibility. A center "Always On" running light alerts drivers to your coming.

                                      

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 hold the batteries in a single 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.

               

All ZEV bikes use special motors with features not shared by any other company in the world.  Look for the ZEV on the motor to know that you are looking at a true ZEV motor
