Narrator: This is the Mantis,
the world's largest all-terrain rideable hexapod.
The futuristic vehicle was designed
and built by Matt Denton
and took four years to create.
As a child, Matt was inspired
by the AT-AT robots from "Star Wars:
The Empire Strikes Back."
The robot is 9 feet tall
and weighs 4,188 pounds.
It wasn't built to be fast.
Instead, Matt wanted to build an insect-like vehicle
that could walk on any surface.
It's powered by a 2.2-liter diesel motor,
which is connected to a hydraulic pump
that supplies hydraulic fluid around the system.
On every leg are three hydraulic actuators
that move each joint.
It's all mapped out on a computer software
that determines how to move the legs accurately.
And in November of 2017, the Mantis was awarded
the Guinness World Record certificate
for the largest rideable hexapod robot.
This may look like a 1972 Beetle,
but it's really a UTV, or utility terrain vehicle.
The UTV Beetle was built by John Tedesco,
who has been working on hot rods with his father
since he was a young boy.
In New Jersey, driving a UTV on the streets is illegal.
John wanted to buy a UTV,
but didn't want to spend all the money
on a vehicle he couldn't drive on a daily basis.
So he welded the body of a 1972 Beetle
onto a Polaris UTV
and then registered the vehicle as a Beetle.
Vehicles that are 25 years or older
are not required to be inspected
as long as they have valid registration
and all the necessary parts to be street-legal,
like lights, seat belts, and blinkers.
The UTV Beetle can traverse muddy roads,
water,
and steep terrain.
It can reach up to 70 miles per hour
and weighs 1,800 pounds.
The car catches a lot of attention on the road,
with many flagging down the vehicle to ask about it.
John hopes to drive the UTV Beetle
through the streets of New York City in the near future.
This motorcycle is made from semitruck parts.
Hi, my name is Jim Gesto.
I'm the creator of the Tower Trike.
I love riding motorcycles,
but I did not like the apparent danger
that came of riding motorcycles.
So I built the Tower Trike as a safer alternative.
I googled the largest motorcycle
that you could possibly build
and still call it a motorcycle,
and we could come up with 11,000 pounds.
After that, it's not a motorcycle.
This one weighs in at 10,900.
Narrator: After repairing semis for 50 years,
Jim had the skill set to bring the Tower Trike to life.
It's powered by a 320-horsepower semi engine
and reaches up to 85 miles per hour.
This is the Swincar e-Spider,
an all-terrain electric vehicle
that's nearly impossible to flip over.
It was developed by French designer Pascal Rambaud.
Here's why it's unstoppable.
Its design is based on a pendulum.
Four independent suspension systems
keep the driver vertical at all times.
This functionality gives the e-Spider
flexibility on hills,
sand,
and rough terrain.
The e-Spider can climb 3,200 feet uphill
on a single charge.
It claims a battery life
of up to four hours on hilly terrain
and has a top speed of 18 miles per hour.
There's also an e-Spider Tandem
and an e-Spider Mobility.
The Tandem has a rear seat for a passenger
and a more powerful motor
to give it the same speed and range
as the standard model.
The e-Spider Mobility is made for people
with limited mobility.
The legs swing up to 90 degrees
for easy transfer to and from a wheelchair.
This is the RollKa.
It's a homemade amusement-park ride
built by YouTuber MasterMilo.
So, how does it work?
This dizzying ride started off as a Ford Ka.
Milo shortened the compact car
and fit it inside of two giant ring wheels.
The wheels on the Ford Ka spin
and make traction within the tracks
of the larger fabricated ring wheels.
Brakes on either side of the vehicle
are used to stop the interior tires from rotating,
and the sudden change in momentum
flips the riders 360 degrees upside down
while moving forward.
The unique build is also fitted with a roll cage
and harnesses for safety.
