HappyRun G300 SE – 4500W Electric Mini Dirt Bike

The G300 SE is where younger riders and smaller-framed adults find a machine that takes them seriously. A 4500W peak mid-drive motor with 220 Nm of torque, full hydraulic suspension, and a compact frame sized for riders from 3'11" to 6'1" — it delivers genuine off-road performance without the bulk of a full-size dirt bike. A 48V 26Ah battery provides up to 45 miles of range, and the integrated lighting and LCD display keep the experience polished from the first ride.

• 4500W peak mid-drive motor, 220 Nm torque — mid-drive placement delivers balanced weight distribution and strong, natural power delivery across varied terrain
• Compact frame for riders 3'11"–6'1" — sized for teens and smaller-framed adults without sacrificing performance or build quality
• 48V 26Ah battery, up to 45 miles range — enough capacity for extended trail sessions without needing a mid-ride recharge
• Full suspension — hydraulic front, coil rear — absorbs trail impacts and keeps the ride controlled across dirt, gravel, and uneven surfaces
• Hydraulic disc brakes (190mm rotors) — consistent, reliable stopping power matched to the bike's performance capability
• 500-lumen LED headlight + LCD display — integrated lighting for low-light riding and a clear display for speed, battery, and mode monitoring
• High-strength carbon steel frame, 330 lb payload — 123.5 lbs with battery; ships free to the contiguous US
