The fully upgraded 2025 HappyRun G300 Pro, with an aluminum alloy forged frame and a newly developed 6500w (Peak) high-performance motor,
is the most cost-effective off-road electric dirt bike !

Inverted front suspension designed specifically for the G300 Pro, high-performance inverted front fork with 11 inches of effective travel.
The rear shock absorber has a stroke of 5 in. Compared with traditional e bike shock absorbers, the vertical rear shock absorber of G300 Pro is equipped with a bolder design, which allows G300 Pro to be as smooth as walking on flat ground in various road conditions and to obtain sufficient buffering in off-road.

As a 50-year-old weekend rider, I’d been eyeing e-bikes for months. After binge-watching YouTube reviews, the Tank G300 Pro stood out like a monster truck at a Prius convention. Reached out to HappyRun’s team �C their answers were clearer than my GPS directions, so I hit “buy.” Assembly? Shockingly simple. Came 90% pre-built, and the included toolkit made the rest feel like LEGO-for-adults. It's 3,000 miles down and this thing’s barely broken a sweat. Why it rules: 1.Hits 48MPH effortlessly (my inner teenager screams every time). 2.Full suspension eats potholes for breakfast �C my back stopped cursing me. 3.Headlight’s brighter than my future, though the taillight could pop more in traffic. Best part? Feeling like a kid on his first BMX again.
