The Campagna Motors T-Rex feels like a different beast compared to some of the others listed here. Campagna's offering is a color-customizable road racer that places two wheels in the front and a single tire behind the passenger compartment. It's certainly not a car, with open sides where the doors might sit, but it's also not a motorcycle, as its fully encompassing roll cage creates a profile akin to high-performance sports cars. The T-Rex RR performs like one, as well, with a Kawasaki-built, 1,441cc inline-four engine that produces 208 horsepower and 116.5 lb.-ft. of torque.

The T-Rex RR is insanely fast, reaching a top speed of 125 miles per hour and accelerating from zero to 60 mph in roughly 4 seconds flat. T-Rex models include a manual six-speed transmission that's shifted sequentially (rather than the standard shift stick that alternates direction to change gear). The T-Rex is a non-leaning model, like the Polaris, Morgan, and Can-Am, meaning it drives more like a car than a motorcycle and won't require the riders to shift their weight along with the roadway's curve.

When it comes to safety, Campagna's T-Rex utilizes ABS antilock braking and incorporates the aforementioned roll cage throughout the chassis. The two bucket seats in the passenger compartment are outfitted with 3-point safety belts as well. The T-Rex includes a reverse gear and integrated backup camera to make all aspects of the drive safe and efficient. For the luxury of performance mixed with immense cool, you're looking at a steep price tag, however. The T-Rex starts at $68,999.
