Front and center at the Cotton Bowl, the Defiant was showcased to a hundred thousand visitors at EDTx! This was the largest event of its kind – but then, what else would you expect in Texas? The Shockwave Motors Team was often talking to dozens of people at a time! The response was amazing! I would never have guessed, in the heart of oil country, there would be such an intense interest in an electric vehicle – but there was! People were snapping pictures continuously on their cell phones, as well as lining up to have their picture made in the Roadster.
The biggest draw, aside from the obvious economy and the pollution free aspects of the Roadster, was the “Fun Factor”. As soon as someone saw the Roadster or had a chance to sit in the cockpit, they realized this was just the vehicle to put a smile on their face and liven up the all too often boring drive to work.
Special thanks go out to Lanny Shivers, Business Development, EDTx, as well as Colleen Crowninshield, Clean Cities, Alt Fuels Specialist, Manager at Tucson Clean Cities, and finally to Trammel S. Crow for founding the event. I also have to give a big thank you to the members of the Shockwave Motors Team that spent over a week on the road and talked to thousands of people in both Texas and Arkansas: Carrie, Jessica, Cortney and James.
We had a great time at the Annual Crusin’ With the Cops Car Show and won the top award for motorcycles! This is a charity event in association with the Fraternal Order of Police, with all proceeds going to the “Cops and Kids Program.”
This summer and fall we are installing a new series of upgrades that should provide a significant increase in the performance of the Roadster. First, the voltage of the battery system is being increased from 144-volts to 168-volts. This enhancement coupled with the new motor will improve both the top speed and range. Additionally, we have concluded our transmission tests and are replacing the multiple gear transmission with a custom designed single speed unit.
Shown below are the new batteries being tested and charged prior to installation in the Roadster.
Check out our May Newsletter for more details about what we have been up too!
Last November, after traveling almost 6,000 miles round trip to the IDTechEx Show in Santa Clara, CA, I must say we had the experience of a lifetime! I am pleased to announce that Shockwave Motors won the 2016 award for the, “Most Significant Innovation in Electric Vehicles”. The judges praised our efforts to design a vehicle from the ground up and our innovative way to allow for three passengers. They also felt our energy efficiency of less than 200 Wh/mile was impressive, since most EVs usually have efficiencies of over 300 Wh/mile.
At Shockwave Motors we make electric cars cool by providing a high performance electric roadster (Autocycle) that’s economical, pollution free, safe, and just plain fun to drive!
Our three-passenger roadster is designed with the daily commuter in mind and has a range of 80 to 100 miles and then plugs into any standard 120-volt outlet for about 8 or 9 hours for a complete recharge. Then the commuter is ready to drive another 80 to 100 miles home. This gives the roadster an effective range of up to 200 miles per day. The top speed is about 75 MPH.
Our performance testing is demonstrating just over a penny a mile for electric power and about 4 cents a mile for battery depreciation. Our prototype, all electric roadster, is getting the equivalent of over 200 miles per gallon!

Here's what others are saying about the roadster!
"I've seen a lot of high tech engineering developments through the years. No question about it: Shockwave Motors practices creative, out-of-this-world innovation!"
"The design of the three-wheeled Defiant EV 3 Roadster© is distinctly 'classic.' It's the electric car that ZZ Top might drive."
"Companies like yours, Elio, and Tesla are not only disruptive, but creating true paradigm shift. It's an exciting time!"
Why three wheels instead of four?
We are able to achieve a high level of efficiency by using a lightweight, yet strong, tubular steel chassis inspired by race cars, coupled with an aerodynamic body. Our unique three-wheel design guarantees less rolling resistance at all speeds and the aerodynamic body significantly reduces drag at higher speeds. The Defiant is a three-wheel vehicle as defined by the Highway and Transportation Board and as such it is included in the definition of a "Motorcycle"; Our roadster complies in every way with the safety requirements and regulations applicable to a motorcycle; and in fact, complies with many of the safety features of a standard car.
As a motorcycle do we have to wear helmets and get a motorcycle license?
In October 2013, the American Association of Motor Vehicles Administrators (AAMVA), a national authority on best policy for all state DMVs and Licensing Bureaus, recommended that fully enclosed, three-wheel vehicles, such as the Defiant, be driven with a standard driver’s license. Additionally, they defined this special class of motorcycle as an Autocycle. For additional details, please see the Best Practices for the Regulation of Three-Wheel Vehicles. California, Oregon and most other states exempt the driver of an enclosed tree-wheeled vehicle from the requirement of obtaining a motorcycle license. Additionally, California, Oregon and most other states also exempt the occupants of a three-wheeled vehicle from the requirement of wearing a helmet if the passengers are enclosed. The roll bar installed on our production vehicles will extend the exemption to our Roadsters even when the top is removed! Of course, check with your state to be sure.
Is stability as issue?
Three factors determine the stability of a three wheeled vehicle, regardless of the design (tadpole vs delta); weight distribution, center of gravity, and how wide is the track. The Defiant is not designed like a top-heavy ATV. The low center of gravity and wide track produces a stable ride with no more possibility of a rollover than you would find in a conventional car. Mr. Robert Q. Riley a noted expert in three-wheel vehicles and designer of the Trimuter, had this to say about vehicle stability, “A conventional, non-tilting three-wheel car can equal the rollover resistance of a four wheel car, provided the location of the center-of-gravity (cg) is low and near the side-by-side wheels.” This is exactly how we have designed our roadsters – and our design was validated by the Québec Institute for Advanced Transportation (ITAQ).
What kind of battery system do you use?
The electric roadster is designed around a 168-volt system. The standard option is a Lithium Iron Phosphate (LiFePO4) large format, prismatic battery system. This is not the same lithium battery in size or format that is used in the Tesla, Chevy Volt, or Nissan Leaf. Some electric vehicles use cells similar in design and size to laptop batteries. The larger size, LiFePO4, prismatic battery cells that we use do not suffer from the thermal instability issues that must be dealt with when thousands of smaller cells are combined to create a battery system. These batteries are able to deliver greater charge density while improving system reliability when compared to thousands of the smaller, cylindrical cell format. Our design also minimizes points of failure and increases serviceability by using fewer cells to achieve the desired system voltage. Since the Lithium battery weighs substantially less than the Lead-acid counterpart, rolling resistances and inertia is reduced and acceleration is improved. To better meet your driving needs, we are offering three different Lithium Iron Phosphate battery sizes. However, should you desire a conventional (Lead-Acid) battery system we will provide that as well. For additional details on the safety of LiFePO4 batteries, please see, “A General Discussion of Li Ion Battery Safety” by Dan Doughty and E. Peter Roth.
How fast will the electric roadster go?
Under typical driving conditions our high performance electric roadster will have a top speed of over 70 MPH. However, vehicle speed varies depending on temperature, terrain, driving style, road conditions, and vehicle payload.
How far will the electric car go?
The range of the electric car is a function of many factors. Driving habits, cruising speed, the terrain, temperature, how big the battery pack is, the overall weight of the car, all influence the range of an electric car. As our vehicle is lightweight (but very strong because of our tubular steel construction), even Lead-acid batteries, provide a range of about 50 miles per charge at 40 miles per hour. With the recommended Lithium Iron Phosphate batteries, the single charge range is 80 to 100 miles and the daily range is up to 200 miles. The roadster comes equipped with a standard Lithium Iron Phosphate battery system that provides a single charge range of up to 50 miles and a daily range of about 100 miles. The largest battery system provides an estimated 175 miles per charge and up to 250 miles per day. At modest speeds, the roadster requires just over 100 watts of electricity to travel one mile. The roadster can travel about 45 miles on the electricity needed to produce just one gallon of gasoline!
How long does it take to charge an electric vehicle?
Our electric cars are designed to plug into any conventional 120 volt outlet. Typically it takes about 8 hours for a full charge, and 4 to 6 hours for an 80% charge. Most of the time, charging is done at night when electrical loads are lowest (and off peak rates may apply). For long distance commutes, the car can also be charged during the day while the driver is at work.
How much does it cost to run?
Normally it costs about a dollar to charge the batteries ($1.75 to recharge our largest LiFePO4 battery); so at that rate, it costs a little over a penny a mile for electricity. Battery depreciation will add another three or four cents a mile to the operating costs. Research shows that maintenance and repair for the electric roadster will be less than 10% of the cost of a typical automobile. Under normal use, our roadster can pay for itself in less than 6 years!
How often do I have to replace the batteries?
Lead-acid batteries may be used and will last about 3 years depending upon how you drive and take care of your batteries. In typical driving, this equates to about 18,000 to 20,000 miles. The Lithium Iron Phosphate batteries (recomended) last two to three times longer than conventional batteries.
Is insurance an issue?
No, insurance is typically not a problem to obtain. Our roadsters register as a motorcycle.
Why electric vehicles over hybrids or fuel cells?
While Hybrids are leaps and bounds ahead of pure internal combustion vehicles they do still use fossil fuel and do still pollute a great deal. Fuel cells are still in the research and development phase and may be decades away from economical commercial production; electric vehicles are available now.
Why Alternating Current motors?
We knew we had to use either a brushless, direct current (BLDC) motor or an alternating current (AC) motor in order to achieve effective regenerative braking. Our goal is to keep the design simple and cost effective, so the preproduction version of the roadster is using an AC motor.
What equipment is standard on the roadsters?
An AM/FM Radio CD with MP3/USB port, cockpit heater, 12-volt power outlet, 168-volt lithium battery, adjustable driver seat, on-demand regenerative braking system, and defroster are standard equipment on the roadsters. Optional equipment includes removable hardtop, sunroof, air conditioning, sport rims, and certain high capacity battery combinations (three different battery capacities available).
Why drive our electric roadster?
