The HappyRun G300 Pro Electric Dirt Bike combines high-speed electric performance, long-range battery capacity, full suspension, and hydraulic braking in an affordable off-road package. With a 6,500W peak motor, 72V 30Ah removable battery, and top speed of up to 50 MPH, the G300 Pro is built for riders who want considerably more performance than a conventional e-bike.

A 19-inch front and 17-inch rear wheel setup, adjustable suspension, five speed levels, and a strong carbon-steel frame make the G300 Pro ready for trails, dirt roads, and recreational off-road riding.

6,500W Peak Electric Motor

The HappyRun G300 Pro is powered by a 72V 3,000W motor capable of producing up to 6,500W peak power.

With strong electric torque and instant throttle response, the G300 Pro delivers the acceleration needed for hills, trails, and challenging terrain while reaching speeds of up to 50 MPH in off-road mode.

Five adjustable speed levels allow riders to progressively control the bike’s performance rather than having full power available immediately.

72V 30Ah Removable Battery

A high-capacity 72V 30Ah lithium battery provides 2,160Wh of energy capacity and is removable for convenient charging.

HappyRun rates the G300 Pro for a maximum range of up to 70 miles under optimal conditions. Actual riding range will vary depending on speed, terrain, rider weight, elevation, temperature, tire pressure, and riding style.

The supplied 5A charger provides a full charge in approximately 5–6 hours.

Up to 50 MPH Top Speed

The G300 Pro offers multiple performance levels for different riding conditions, with its highest off-road setting capable of reaching up to 50 MPH.

For riders looking for a fast electric dirt bike without moving into the price range of premium electric motorcycles, the G300 Pro offers an impressive combination of speed, battery capacity, and off-road equipment.

Full Suspension for Off-Road Riding

The G300 Pro features a full-suspension chassis designed to improve control and comfort over uneven terrain.

An adjustable aluminum-alloy front fork provides approximately 80–120mm of travel, while the rear suspension helps absorb impacts and maintain traction on trails, dirt, and rough surfaces.

Hydraulic Disc Brakes

Performance at higher speeds requires dependable braking. The HappyRun G300 Pro uses hydraulic disc brakes with large brake rotors for controlled stopping power.

The braking system includes:

• 180mm front brake rotor
• 203mm rear brake rotor
• Hydraulic brake system
• Aluminum-alloy brake levers

19-Inch Front and 17-Inch Rear Off-Road Wheels

The G300 Pro uses a staggered off-road wheel configuration with a 70/100-19 front tire and 70/100-17 rear tire.

The larger front wheel helps the bike roll over obstacles and uneven terrain, while the off-road tread provides traction on loose and challenging surfaces.

Full-Color LCD Display

A centrally mounted full-color LCD display keeps essential riding information easy to see.

Riders can monitor speed, battery status, riding level, mileage, and other important information while riding.

Powerful LED Lighting

The G300 Pro includes a 2,000-lumen LED headlight for improved visibility, along with an integrated rear light featuring a braking indicator.

The lighting system adds functionality for lower-light riding while giving the bike a distinctive modern appearance.
