Holy &%$#, what is this thing?

It’s called a Raht Racer, or just Raht.  Raht is an acronym for Recharging Anthro-Hybrid Transcycle.

Is it a bike?

It has pedals like a bike and the pedals make you go, but they are connected to a generator-accelerator system, not the wheels. Your physical work goes into making electricity and forward motion indirectly by contributing to the battery and hence, the motor. When you pedal, the system multiplies, or boosts your pedal effort to automobile/motorcycle speeds.

Why will it make me feel like Superman?

Because when you pedal it, you go as fast as a car.

Do you have to pedal really hard?

No.  You pedal as you would an ordinary bicycle; the system boosts your input/effort.   You can set the boost level you want to be; minimum boost – harder pedal effort; maximum boost – less pedal effort. And you never have to pedal the Raht if you don’t want to – it will still function as an electric vehicle.  It has a throttle always available on the steering wheel.

Do you need a motorcycle license?

It is regulated by the government as a motorcycle, but in most states you won’t need a motorcycle license to drive it; just motorcycle plates.

Is it a car?

The Raht is a motorcycle with the safety features of a car.  Some people are referring to this kind of new class of vehicle as a “Cabin Cycle”, or “Auto Cycle”.

Is it electric?

Yes, the first prototype has a 4.5 kWh lithium ion battery pack and electric motor.  The production model will have a 13kWh battery.

Is it fast?

Yes, very fast. It’s an electric vehicle, so acceleration is quick with top speed up to 95 mph.

Do you recharge the battery when you pedal?

If you are moving, the motor will eat up any power you make and you will extend your range.  If you are stationary and pedal, you will charge the battery.

How much power can I contribute to the car when I pedal?

This is a highly variable number and we would be dishonest if we made big claims.  If you work hard, you may contribute between 7% and 10%. Once we have further testing of a true production vehicle, we will have more accurate numbers.

Where’s the motor?

In the prototype, It’s in the rear wheel, it’s a hub motor, 19hp.  The production model may have the motor mid-mounted with a belt drive.

How much does it weigh?

About 530 pounds.

So, you can just drive it without any pedaling?

Yes, remember the pedals are not connected to the drivetrain (wheels), so it will go whether you pedal or not. Pedaling extends the range of the car.

What happens when you do pedal?

There are 2 modes to choose from when you drive the Raht: EV Mode and Cyclecar Mode.  In EV Mode, you accelerate and decelerate the Raht with a throttle, like when you press the gas pedal in a car, or twist a motorcycle hand throttle. The pedals are not driving the car.  If you want to pedal and get a workout, you can run an exercise profile program, much like an electronic exercise bike at a health club. This is why the Raht is known as the “drivable exercise machine”. The program runs and you pedal as you drive. All of your energy is captured by the generator system, none of it goes to waste.  Workout profiles are managed by an on-board computer, which also has GPS and all of your workout data is reported to you in real time.

In Cyclecar Mode, the pedals respond to pedal input from your legs just like a conventional bike, only multiplied many, many times. Remember, the pedals are not connected to the wheels. The computer in the Raht calculates your pedal input, multiplies it and sends the information to the motor controller. It’s a” fly by wire” system.  The amount of boost is completely variable like the volume knob on your stereo.  In Cyclecar mode, you can tell the system to follow the actual terrain and the pedal resistance will vary according to the geography of where you are actually driving, or you can set it to a pre-programmed profile and again, run it like a machine at the gym.

Is it a clean, efficient vehicle?

Kronfeld Motors is a technology companyWe employ hardware, software, photovoltaic, air pressure, generators and other systems to capture, recapture and maximize every drop of energy. You’ve probably heard of regenerative braking, (brakes that use generators to slow a car down and put energy back into the battery)regen is one of many tools and design elements we use, in addition to proprietary tech we develop to make our vehicle radically efficient. 

It’s not safe though, is it?

The Raht has a reinforced fiberglass body, roll cage frame, anti-lock brakes, seat belts, traction control, full automotive grade lighting and more. It may not be an SUV, or sedan, but the Raht is much safer than a motorcycle, or a bicycle on a busy street.
