The HappyRun G300 Pro is a fully upgraded 2025 high-performance electric dirt bike built for adults who demand serious off-road power at an accessible price point. Driven by a 3000W motor with 6500W peak output and a 72V 30Ah lithium battery, it reaches 50 MPH in Off-Road mode and 28 MPH in City mode, with a range exceeding 70 miles per charge. The 5A fast charger replenishes the battery in just 5–6 hours, getting you back on the trail quickly. Designed for riders from 5'1" to 6'5" with a maximum payload of 350 lbs.
The G300 Pro's aluminum alloy forged frame and HappyRun's independently developed HR full suspension system — featuring an adjustable aluminum alloy front fork with 80–120mm travel — absorb the harshest terrain impacts while maintaining precise handling at high speeds. Front 70/100-19 and rear 70/100-17 off-road tires deliver aggressive traction across dirt, gravel, and uneven trail surfaces. Hydraulic disc brakes with a 180mm front rotor and 203mm rear rotor provide powerful, fade-resistant stopping performance in all conditions.
Multiple riding modes and an adjustable throttle curve let you fine-tune performance to match terrain and rider preference — from controlled urban commuting to full-power off-road riding. The mid-mounted color LCD display delivers clear real-time readouts of speed, battery, and ride data, while a 2000-lumen LED headlight and integrated braking taillight ensure full visibility for early morning and night rides. IPX5 waterproofing keeps all electronics protected in wet and muddy conditions.
At 136.8 lbs with a compact packaged footprint of 57.3" x 13.2" x 29.5", the G300 Pro strikes a balance between trail-ready capability and practical transportability — easily loaded into a truck bed or trailer for adventure trips. A 31" seat height and wide rider height range make it accessible to a broad spectrum of adult riders.
