There are a wide range of power-train options for the S-Series that alter the range, speed and price, give us a call and we would be happy to find the best fit for your needs

The S Series bikes were designed to utilize the most recent changes in bike technology with LED lighting where possible, the largest possible under seat storage in a non maxi scooter bike, the lowest possible CG, and the addition of locking front compartments found only on much larger bikes. They pack the most range and power of any scooter on the market unless compared against larger frame, heavier, maxi scooters. But even when compared in that manner, they still have more power.
Unique among performance electric vehicles, ZEV products use a hub motor where the motor is contained completely inside the rear wheel. The outside of the motor is the tire rim and the axle is fixed as the stator, thereby eliminating all moving parts except the bearings. This eliminates the need for maintenance of a chain or belt drive and the efficiency losses that arise from using chains and belts. The time needed for the motor to spool up in rpm to generate power like bikes that are powered by a small diameter motor through a chain or belt is also eliminated making the bike very responsive and quick. The torque is instantaneous.

Look closer and you will see that this bike is really a sport bike in disguise. The visual cues are there: the big, no flex swingarm for excellent handling, the high end gas shocks that only expensive sport bikes approaching $10,000 have. 
Notice the modular wheel and motor system that is only sold on a ZEV. Under the bodywork is a high torsional rigid frame unlike any "scooter" comprised of 1.25 OD steel tubing. This is not a little scooter despite its very light weight. The wheelbase is 2.5 inches (6.35 cm) longer than a Honda CBR1000 RR chassis for excellent high speed handling. The ground clearance is excellent with no grounding in the curves in road racing. 

Energy saving 3-speed “Electronic Transmission” controller available in 3 different power settings. This is not an actual transmission, but a computer program that allows the controller to make the motor behave as if having a transmission.
Battery pack seated as low as possible in the chassis to put the bike mass at the axle. Only 6.5 inches from the ground to the battery box bottom. This is a radically lower center of gravity than bikes like the Victory or ZERO electric motorcycles that carries their battery weight above the axle and its CG near the top of the wheel. This allows our bike to be panic-stopped without picking up the back wheel or diving down on the front wheel.

S 15000 LR  

The S-15000 LR was made to pack the largest possible size battery pack for the maximum range into the smallest physical size bike without jumping to a maxi scooter style. The shorter wheelbase compared to a maxi scooter style such as our LRC makes the S-15000 feel more nimble and quick. Z Electric Vehicle has the reputation as the manufacturer of “The World’s Fastest and Longest Range Electric Scooters”. We reinforced that reputation with our S-15000 LR electric motor scooter boasting 130 km/80 mile range and speeds to 120 km/h /78 mph.  

The S-15000 LR utilizes the largest lithium battery pack possible to fit in a non maxi scooter. It is in fact the same battery pack as in the ZEV LRC6.

ZEV S15000 BEATS THE BMW C EVOLUTION ELECTRIC MOTOR SCOOTER by a wide margin.
  • The ZEV has 20% more range than advertised by BMW.
  • The BMW is an incredibly heavy bike at 265 kg / 583 lbs ( according to http://www.bmw-motorrad.com) Over 81kg /179 lbs more heavy than the ZEV. 
  • The ZEV has has about the same under seat storage area as the BMW, but is equipped with a top box direct from the factory for 3 times more storage space than the BMW.  
  • The ZEV costs 45% less than the BMW.
  • The ZEV is faster than the advertised speed of the BMW 
  • The ZEV does not have the belt and sprocket drive wear and maintenance points of the BMW.
  • The ZEV has 150% faster charging rate than the BMW.
  • The seat height of the ZEV is only 28 inches / 711 mm compared to the 30 inches/ 780 mm of the BMW.
  • The ZEV has a much larger, more weather protection windscreen and front fairing protection.  

In Short --The ZEV is lighter, faster, longer range, more storage, more weather proof, lower seat, less maintenance points, and twice the range of the BMW at a far lower cost. 


BATTERY SYSTEMS 

ZEV uses lithium battery in the S15000, S7100, S6100, and S4100 lithium
This battery pack utilizes Li-ion LFMP chemistry. This type of lithium battery is used in all ZEV models and is unusual as they have eight connection fasteners on each battery instead of the normal two. (Each terminal end has 4 fasteners) This makes it virtually impossible for the battery to vibrate and loosen the terminal connections.  

ZEV uses lead silicate battery in the S4000L, S6000L. These are lead styled battery, but they use a caustic silicate fluid, not acid. This eliminates sulfating of the battery and the short life of lead acid battery. The battery can also hold their charge for over 6 months without degragation.

The 6000 L might seem a bit in conflict with the ZEV image of high performance. ZEV is mostly known for its high tech, 100 mile (160 km) range / 75 – 80 mph (120 – 130 kmh) speed lithium battery powered bikes. Equally, the press has seemed to keep its focus on new and exotic battery technology. But for the vast majority of the population, their needs and use patterns could best be served by a new approach, rather than a new technology. The vast majority of the public needs a vehicle to commute to work less than 20 miles. The achieved goal of the new 6000 L for ZEV engineers was to keep the speed up to over 62 mph /100 Km/h while exceeding that general public need with a range of 50 miles / 80 km in open roads, and 25 miles / 40 km in heavy traffic while reducing the weight of the vehicle and its cost. With the world economy not exactly booming, the intent was to try to create the maximum value product for the market and to drive down the sale price.

While the news has been full of stories of new technology in exotic battery, the technology of the lead battery has steadily progressed also. ZEV was able to gain 11.2% in kwh capacity in the lead battery in just the last year and a similar decrease in weight while the cost went down slightly per battery, regardless of the kwh capacity. The historical lead battery problem of plate sulphating based on the use of sulphuric acid does not exist with these new batteries as the normal acid is replaced with an electrolyte of a liquid low sodium silicate compound. Additionally, the non-acid lead battery can have a quicker recharge time rivaling on the street lithium bikes and low temperature performance does not suffer.

The ZEV6000 uses a 72 volt nominal (84 volt peak) system with a capacity of 4.2 kwh. The cost of this is $600 compared to $1750 for a ZEV equivalent lithium system (or $5000 in some brands of electric bike). The Battery Management System (BMS) for the lithium battery is also not needed for the lead battery and assembly times lower with the easier installation, further reducing costs. As these cost savings are always multiplied by dealer margins, the savings are significant while not one bit of performance is lost. The $600 cost of a full battery pack is also a factor when the time comes for a customer to eventually replace their battery.

At 50 Ah/battery, the new lead batteries are larger than the equal Ah competitors' lithium battery but at a heavier weight. The decision was made to just use more lead battery than the number of lithium batteries that the competitors used. The results using the new high-capacity lead battery was a 4.2 kwh capacity bike vs the competitions' lithium 2.6 kwh. The extra battery raised the ZEV speed 15% over its lithium competitor with a 37% range advantage, and only a weight disadvantage, while enabling lowering of the price under all similar performance comparisons. By lowering the battery box slightly, the balance of the lead battery bike was made to equal the lighter lithium bike.

The lead battery offers extreme recyclability for the greenest options. Lead batteries are constantly recycled and the new battery can go right into existing recycle programs. Lead battery systems also seem to have appeal to riders/owners who maintain their own bikes. Without the BMS system of a lithium bike, the lead battery bike is a quick and easy change out when the time comes for even a novice mechanic.

The Silicate lead battery used by ZEV are a completely different battery than the old lead sulfuric acid battery. They use a sodium silicate salt as the electrolyte. 

  • They have only about 10% of the internal resistance of the old sulfuric acid battery. This allows these batteries to be charged in ½ the time of normal lead acid battery. 
  • The discharge ability is much better allowing rapid vehicle acceleration with up to 4.5 times the ability to discharge without damage. 
  • There is little or no temperature increases during charging or discharging. 
  • The battery is far less sensitive to temperature being able to work normally at -50 C. 
  • The battery has no memory. 
  • The electrolyte is the ultimate green battery fluid as it can be used as a fertilizer. 
  • The shelf life is in excess of 12 months without losing charge. So an unused vehicle does not run itself down. 
  • The battery are non explosive. 
  • The battery can be recharged at high currents of .8 to 1 C. 
  • High discharge rates are not a problem given the low internal resistance. 
  • There is no acid mist produced by charging. 
  • The battery can be fully deep charged through over 500 cycles 
  • The energy storage to weight ratio is about 24% better than lead acid.    
Customer Testimonials

S8500 (NOW THE S15000)

 Email from a ZEV S8500 owner to a possible buyer 
"We had the Vespa 250 Gran Tourisimo. The ZEV we purchased was a perfect replacement. It has as much get up and go off the line and over the long stretch. It holds its charge much longer than anticipated and we could not have asked for a better replacement. In our situation sometimes we went 3 months without running the Vespa. In Houston's heat, it would cause the fuel to gum up and the Vespa would not start.  No issues with the ZEV. In fact, no issues of any kind. When we need to use it, we simply turn it on and it goes. It's fast." 
 DB, Houston Texas

"I own a Zev 8500LR in China. It towers above everything else, in size, quality, performance and looks. At last I can now explore outside the city and travel from city to city. So happy to have this electric bike." R. Allen, Beihai China.
"Every day, people look at the bike and ask questions. If I stay stationary for more than a minute I have a small crowd starts to gather. Yesterday the traffic police came over to me and looked all round the bike, smiled and said beautiful bike. They never asked about my license (I still haven't received the number plate but have the receipt if they want to see it)." 
 Ron, S China

S7100

I managed get 50 miles out of a charge today riding to a Big Basin Redwoods State Park. Average speed was 30mph, tooling around mountain roads. Pulled 37AH out of the pack. --- the controller never shutdown." 
 Brent

"I also rode the world’s fastest electric scooter, the 7100 watt ZEV, and I can tell you that it is a rocket ship fast enough to safely get you through hostile urban traffic and more than quick enough to pull you clear of traffic at the stoplight Grand Prix. It ---- offer(s) just about everything you need from an electric commuter."
GIZMAG Editor at Koln International Motorcycle Show

 "FYI - My daily trip is averaging 33 miles without charging so far. That is hauling 280 lbs "
RS, Pa.

"--I am thoroughly enjoying your electric motor scooter. I thank you for your good work in designing and manufacturing this machine." Bob C, Washington State

"I love riding this bike to work everyday. I ride 16 miles to work and recharge at work everyday. I use 1.8 kw going to work uphill and 1.5 kw coming home."  TT, UT

"The bike is working perfectly! Your design and engineering is super! Great machine! Thank you so very much."  
 PL

"I made two trips each over 50 miles! The charging after each trip was 3.3 KW/h's. I keep the speed down not using third gear, my speed was around 30 to 35 mph. I am pushing the range every week and I believe I can reach 60 miles on one charge. "
