HappyRun | G300 SE Ultra Mid-Drive Electric Dirt Bike for Teens & Adults

HappyRun G300 SE Ultra 6000W Mid-Drive Electric Dirt Bike - 60V 31Ah Full Suspension Off-Road E-Bike

The G300 SE Ultra takes the mid-drive architecture of the G300 SE and pushes every number further. A 60V 6000W peak mid-drive motor produces 240 Nm of torque - 20 Nm more than the SE - and drives it through the gears from the center of the frame for balanced weight distribution that stays predictable on steep climbs, loose dirt, and high-speed trail sections. Top speed reaches 44 mph. The 60V electrical system delivers more sustained power under load than the SE's 48V platform, which translates to less voltage sag on long climbs and more consistent acceleration throughout the battery's charge cycle. Full suspension with a hydraulic front fork and rear spring shock absorber keeps both tires planted over rocks, roots, and jumps, while dual hydraulic disc brakes with oversized 190mm rotors bring everything back under control without fade.

A 60V 31Ah high-density lithium battery pushes range up to 65 miles per charge, and the IPX5 waterproof rating means mud, rain, puddle crossings, and trail spray do not send you home early. The cockpit is built for off-road focus: a high-visibility digital display shows speed, battery, and ride data at a glance, and a 700-lumen LED headlight provides genuine trail illumination for dawn patrols and after-dark sessions. Staggered off-road tires - 17-inch front, 14-inch rear - match the moto-style geometry, with a 31.9-inch seat height that fits riders from 3'11" to 6'1" and a 350 lb max load capacity built into a frame that measures 69.3 inches long. This is the top of the G300 lineup, designed for riders who already know what a mid-drive can do and want more of it.

Features

• 60V 6000W Peak Mid-Drive Motor (240 Nm Torque) - Center-mounted motor delivers power through the gears for maximum climbing efficiency and balanced handling. 240 Nm of torque exceeds the G300 SE by 20 Nm, with the 60V system providing more consistent power delivery and less voltage sag under sustained load.
• 60V 31Ah High-Density Lithium Battery - Delivers up to 65 miles per charge with a higher-voltage platform that maintains performance deeper into the discharge cycle. Sufficient capacity for full-day trail sessions without mid-ride charging stops.
• IPX5 Waterproof Rating - Sealed motor, battery, and electrical components withstand sustained water jets from any direction. Ride through mud, rain, puddles, and trail runoff without worrying about water damage to the drivetrain or electronics.
• Full Suspension (Hydraulic Front Fork, Rear Spring Shock) - Hydraulic front fork absorbs trail impacts with progressive damping, while the rear spring shock keeps the back wheel planted over rough terrain. Combined travel handles roots, rocks, drops, and uneven surfaces without transmitting impacts to the rider.
• Dual Hydraulic Disc Brakes with 190mm Rotors - Oversized rotors and hydraulic calipers deliver progressive, fade-resistant stopping power calibrated for 44 mph top speeds and 350 lb loaded weight. Consistent lever feel whether cold or after extended descents.
• 700-Lumen LED Headlight - Genuine trail-grade illumination for low-light and after-dark riding. 700 lumens lights up the trail surface ahead, not just makes you visible to others.
• High-Visibility Digital Display - Clean cockpit display shows real-time speed, battery level, trip distance, and assist mode. Positioned and sized for quick reads without taking your eyes off the trail.
• Staggered Off-Road Tires (Front 17-inch, Rear 14-inch) - Moto-style staggered sizing optimizes each wheel for its job: larger front for obstacle clearance and steering stability, smaller rear for traction and acceleration grip on loose surfaces.
• 350 lb Max Load Capacity - Reinforced frame and components support rider and gear loads up to 350 lbs, 20 lbs above the standard Tank models, with a low 31.9-inch seat height that keeps the center of gravity manageable.
