Created For Snow Traction, The Monster Chopper Combines Giant Backhoe Wheels, Powerful Engine, And Hydraulic Steering In A Unique Engineering

The Monster Chopper integrates a select group of motorcycles that impress with their size and boldness. It’s not for road or track performance, nor for its striking appearance. The highlight comes from the giant wheels, which give the model a unique and imposing character.

Created by Grind Hard Plumbing Co., the bike was designed for snow traction. The 46-inch tires, equivalent to 1.17 meters in height, already deliver the scale of the project.

To move this mammoth on wheels, the group — known on YouTube for creating unusual vehicles — installed a KTM engine. And, to make control possible, they resorted to hydraulic steering.

Engineering On A Large Scale

The Monster Chopper is not the first bold project from Grind Hard Plumbing Co. On their social media, you can find everything from a goalie car with a Yamaha R1 engine to sports bikes transformed into snow motorcycles.

The new creation, however, stands out for combining backhoe wheels with a high-performance engine.

The chosen one was the powertrain from a KTM 1290 Super Adventure, with 160 hp at 6,750 rpm and a maximum torque of 140 Nm.

The sound of the engine combines with the metallic noise of the tire pins, creating a unique experience.

The hand-built frame, without fairings, required many hours of work and autogenous welding. In the end, the bike can be described as a robust chassis mounted on colossal tires.

Challenge To Maneuver

The most important thing is that, besides brute strength, the Monster Chopper needed control. For that, Grind Hard Plumbing Co. adapted a hydraulic steering system similar to the one used in the Bimota Tesi.

The mechanism central to the front wheel hub, although simpler, guarantees efficient operation.

The suspension received parts from the frame of a Honda CBR900RR, reinforcing the mixture of components from different models to achieve the desired result.

However, riding the bike is not a simple task. As shown in the released video, the rider keeps their feet close to the ground to balance the weight and height of the machine.

According to the creators, adjustments will still be made to improve drivability and allow for longer distances than the few meters recorded in the footage.

Thus, the Monster Chopper establishes itself as another example of the bold and creative work of the group, which continues to explore the limits of engineering on two wheels.

Challenge To Maneuver

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

Study solves great ancient mystery: remains of Philip II, father of Alexander the Great, are identified in Vergina and resolves the enigma of the Macedonian royal tombs that had lasted half a century.

Australia prepares to dredge 96.5 million m³ in Moreton Bay to deepen, widen, and realign channels of the Port of Brisbane, in a project of up to 25 years designed to accommodate larger ships and enhance maritime safety and regional port efficiency.

Larger than the Toyota Hilux and with a towing capacity of 3.5 tons, the new MG U9 2026 features a 2.5 turbodiesel engine, 520 Nm, 4×4 traction with three locks, and an almost full-size build.

Portugal installs two giant underwater sockets to draw water from the Atlantic and create a €107.9 million desalination plant in the Algarve capable of producing 43.2 million liters of potable water per day with ocean intake 2 km from the coast.

South Africa created giant concrete blocks in the shape of a twisted “H” that reached 30 tons and became a global shield against destructive waves; dolosse were born after a storm devastated the port of East London in 1963 and today protect ports, beaches, and breakwaters on various continents.

Giant geotextile bags filled with sand have become flexible barriers against erosion in America, Europe, Asia, and Oceania; the technology replaces tons of concrete and rock with permeable tubes that dissipate waves and protect beaches, dunes, and riverbanks.

More than 500 Marines, robots, drones, and armored vehicles are deployed in Rio de Janeiro for the UN to certify Brazil at the highest level of readiness for peacekeeping missions. It is the first force in the country to achieve this status in all of history.

A large part of the Netherlands lies below sea level and remains dry only because an invisible machine of dikes, pumps, and giant gates works nonstop, a system born from the tragedy of 1953, when the North Sea invaded the country and killed 1,836 people.

The largest bridge in Finland has just been inaugurated and cars simply cannot pass on it; only trams, bicycles, and pedestrians are allowed to cross the 1.2 km giant with a 135-meter pillar over the Baltic Sea.

Larger than Belgium and nestled at the mouth of the Amazon, Marajó Island is a giant that Brazil has forgotten, surrounded by water and energy on all sides, yet still isolated, poor, and dependent on diesel brought by barge.

Weighing as much as nine nuclear aircraft carriers, the Pioneering Spirit is the largest ship ever built and was made for a single task that no other machine in the world can accomplish: removing entire oil platforms from the seabed of the North Sea in one go.
