Rambo Venom RS: A 10,000-Watt Electric Dirt Bike Built for the Backcountry

Rambo Bikes has spent years building electric bikes around the needs of hunters—quiet access, off-road capability and the ability to cover more ground without burning energy before the hunt begins.

The new Rambo Venom RS takes that philosophy somewhere considerably different.

This isn’t simply another fat-tire hunting e-bike with a bigger motor. Rambo calls the Venom RS its first true high-performance electric dirt bike, and the numbers make the distinction pretty clear: 4,000 watts of continuous power, up to 10,000 watts at peak, 390 Nm of torque and a top speed of 38 mph.

In other words, Rambo hasn’t just turned up the power on its existing formula. It has moved into another category of off-road machine.

Rambo Venom RS Moves Beyond the Traditional E-Bike

Rambo says development of the Venom RS grew out of both its own field experience and feedback from customers who were asking for more power, speed and range.

Those customers weren’t limiting their bikes to maintained roads and easy trails. They were using them on hunting properties, farms, ranches and rough backcountry routes, often asking their equipment to tackle increasingly difficult terrain.

The Venom RS is Rambo’s response.

At its center is a low-speed permanent magnet synchronous motor rated at 4,000 watts of continuous power and up to 10,000 watts at peak. Peak torque is rated at 390 Nm.

That’s enough output to make this machine fundamentally different from the typical hunting e-bike, with Rambo positioning the Venom RS for steep climbs, rapid acceleration and more aggressive off-road riding.

Up to 75 Miles of Rated Range

Feeding that motor is a removable 72-volt, 35Ah lithium-ion battery.

Rambo rates the Venom RS range at up to 75 miles, although—as with any electric vehicle—actual range will depend heavily on terrain, rider weight, speed, riding mode, temperature and how frequently the motor is asked to deliver maximum power.

Three riding modes—Eco, Sport and Sport+—allow riders to adjust power delivery through the twist throttle.

For hunters, that combination provides some interesting possibilities. A rider could conserve battery on easier access roads, then call on considerably more power when the route turns steep or technical.

A 2-inch TFT display provides speed, battery and ride information and includes app connectivity.

Built for Rougher Terrain

More motor requires more chassis.

The Rambo Venom RS uses a forged 6061-T6 aluminum frame along with FastAce suspension front and rear. The front fork provides 200 mm of travel with adjustable compression and rebound damping, while a FastAce piggyback rear shock handles suspension duties at the back.

That gives the Venom RS substantially more suspension travel than riders would normally associate with an electric hunting bicycle.

Stopping comes from 203 mm hydraulic disc brakes front and rear, while a reinforced chain-and-sprocket drivetrain transfers power to the rear wheel.

The result is a machine designed less around pedaling down a gravel road and more around maintaining control when the trail gets rocky, rutted or steep.

What Does the Rambo Venom RS Offer Hunters?

The hunting applications are easy to see.

A machine capable of covering ground quickly could be useful for scouting large properties, reaching remote trailheads, checking distant trail cameras or traveling long networks of ranch and private-land roads. In steep country, the Venom RS’s torque could also make routes possible that would be punishing on a conventional e-bike.

But there is an important distinction.

At 130 pounds with a 220-pound maximum load capacity, the Venom RS isn’t designed primarily as a cargo hauler or game-retrieval machine. Hunters looking to carry substantial loads may find another type of hunting e-bike better suited to that particular job.

The Venom RS is instead built around performance: reaching difficult country, climbing aggressively and covering ground.

That's a meaningful departure from simply building a bigger version of a conventional hunting bike.

Know Where You Can Ride It

That added performance also means riders shouldn’t assume the Venom RS can go everywhere a conventional e-bike is permitted.

With 4,000 watts of continuous power and a 38-mph top speed, this is a high-performance electric dirt bike, not a typical Class 1, Class 2 or Class 3 e-bike. Rules governing electric bikes, motorized vehicles and off-highway vehicles vary by state, property and land-management agency.

Hunters should check the regulations for the specific property or trail system before taking the Venom RS into the field.

On private property, ranches and other areas where a high-powered electric dirt bike is permitted, however, its combination of torque, range and suspension opens some intriguing possibilities.

A Different Kind of Rambo

Rambo built its reputation around electric bikes intended to help hunters travel farther and work more efficiently outdoors. The Rambo Venom RS carries that same outdoor focus into substantially more aggressive territory.

That's what makes the Venom interesting.

It’s not merely Rambo’s newest hunting e-bike. It’s evidence that the company sees a market beyond the traditional boundaries of the category—among hunters and other outdoor users who want electric power but need considerably more performance than a conventional e-bike was designed to provide.

When the gravel road becomes a rough trail and the terrain gets steep, the Venom RS was built for what comes next.
