Built for Speed. Built for the Trails.
The HappyRun G300 Pro is a full-size electric dirt bike built for riders who want serious power without the noise and maintenance of a gas bike. With a 72V 30Ah removable battery, 3,000W motor with 6,500W peak output, and speeds up to 50 MPH, the G300 Pro brings serious performance to the trail.
The G300 Pro features a forged carbon steel frame, full suspension, hydraulic disc brakes, high-traction off-road tires, and a full-color LCD display. Whether you're hitting the trails, exploring off-road terrain, or cruising around town, the G300 Pro is built to handle it.
⚡ 6,500W Peak Motor
The 72V motor delivers 3,000W of rated power and up to 6,500W peak output, giving the G300 Pro the torque and acceleration needed for serious off-road riding. Five adjustable speed levels let you control the bike to match your riding conditions.
🔋 72V 30Ah Removable Battery
The large 72V 30Ah battery provides up to 70 miles of claimed range, depending on riding conditions and riding style. The removable design also makes charging more convenient. Fast charging can reach approximately 80% in 2.5 hours, with a full charge taking around 5–6 hours.
🏁 Up to 50 MPH
The G300 Pro is capable of reaching up to 50 MPH in off-road configuration, giving riders plenty of power for trails and private-property riding.
Speed Classes:
Class 1/2: 13 MPH
Class 3/4: 25 MPH
Class 5 Off-Road: Up to 50 MPH
🛞 Full Suspension & Off-Road Setup
The G300 Pro uses an inverted front fork paired with a heavy-duty rear shock to absorb bumps and rough terrain. Its 19" front / 17" rear wheel setup and aggressive off-road tires provide traction and stability across loose, uneven, and rough surfaces.
🛑 Hydraulic Disc Brakes
Large hydraulic disc brakes provide strong, controlled stopping power when you need it most. They're designed to give the G300 Pro reliable braking performance during higher-speed and off-road riding.
💡 Bright Lighting & Integrated Turn Signals
A 2,000-lumen front headlight helps light up the path ahead, while the integrated rear lighting and turn signal system increases visibility to other riders and road users.
📟 Full-Color LCD Display
