The Big Rig: World's Lightest 4WD Off-Road Accessible Vehicle

The Big Rig

Four years after the launch of the original off-road "Not a Wheelchair" called The Rig, the creators have introduced an even more powerful and versatile version: The Big Rig. This four-wheel-drive accessible vehicle is equipped with four times the power and four times the motor compared to its predecessor, revolutionizing off-road accessibility for those with mobility challenges. Weighing just 210 pounds, the Big Rig is the world’s lightest accessible vehicle of its kind, designed to bring enhanced mobility to a variety of terrains that were previously inaccessible for wheelchair users.

Key Features and Advancements

Increased Power and Efficiency
The Big Rig boasts four independent 1,000-watt e-bike hub motors, which make the vehicle far more powerful and efficient than the original Rig. Each motor is mounted into standard off-the-shelf 20x4 fat bike tires. The increased power means that the Big Rig can handle more difficult terrain, including snow, sand, and dirt trails, while maintaining exceptional control and speed. The top speed is 13 mph, achieved quickly with 7 kilowatts of power when in level five driving mode.

Innovative Design for All-Terrain Use
This vehicle excels in environments where traditional wheelchairs struggle, such as snow-covered mountains and sandy beaches. While it performs admirably in extreme conditions, it feels most at home on dirt roads and backcountry hiking trails. Its beefed-up suspension system ensures a smoother ride over rough terrain, and its hydraulic brakes and steering rods provide excellent control.

Accessibility and Legal Considerations
According to the Americans with Disabilities Act (ADA), individuals with medically recognized physical impairments can use mobility devices like The Big Rig in public areas where pedestrians are allowed. This makes the Big Rig a versatile and legally recognized mode of transportation for outdoor environments. However, it is not intended for indoor use.

For those without a recognized medical impairment, certain public areas may restrict its use, similar to e-bikes, but mobility devices generally receive broader access due to their essential nature.

The Big Rig in Action

Durability and Versatility

Tough Tires and Anti-Flat Technology
One of the standout features of The Big Rig is its ability to handle tough terrain without compromising the rider’s experience. It comes equipped with nearly invincible Tannus Armor tire inserts, which protect against 95% of common flats. These inserts ensure that riders can enjoy their off-road adventures without worrying about punctures from debris or sharp objects on the trail.

Increased Weight Capacity and Towing Capabilities
The Big Rig is designed to carry more than its predecessor, with a weight capacity of 275 pounds (passenger and cargo combined). It can also tow a 200-pound payload for up to 20 miles on relatively flat terrain, making it ideal for camping trips, farm work, or other outdoor activities that require hauling supplies. A custom gooseneck trailer can be attached to the back, allowing easy access to items without the need to leave the seat.

Limitations and Trade-offs

Despite its many advantages, the Big Rig is not without limitations. For example, it lacks traction control, which can make navigating steep slopes or deep sand more challenging. Additionally, while hub motors are exceptionally quiet, they are not known for their torque, meaning that starting on steep inclines or in heavy sand can be difficult, particularly when carrying a full payload. Riders should also be mindful of the impact that extra weight has on climbing performance, as physics plays a role in limiting what the vehicle can achieve with heavier loads.

Affordability and Accessibility

One of the primary goals behind the creation of The Big Rig is to offer an affordable alternative to expensive off-road mobility devices. The original two-wheel-drive version of The Rig remains available for $5,099, while the four-wheel-drive Big Rig is priced at just under $12,499. Despite having four times the power, the Big Rig is still thousands of dollars cheaper than similar products on the market, making it a highly competitive option for individuals seeking affordable mobility solutions.

Final Thoughts

The Big Rig represents a significant step forward in off-road mobility for people with disabilities. While it has some limitations, its combination of power, versatility, and affordability makes it an attractive option for those who want to explore the outdoors with greater independence.

For anyone in search of an off-road mobility solution, The Big Rig is a game-changer, offering an unparalleled blend of performance, affordability, and accessibility. Whether tackling mountain trails or sandy beaches, this innovative vehicle opens up new possibilities for adventure and independence.
