FAQs

The Happyrun G300 Pro is a high-performance electric moto capable of reaching a top speed of 50 mph via its 72V 6500W peak motor. For versatility and legal compliance, it features multi-class speed settings: Class 1/2 (13 mph) for city paths, Class 3/4 (25 mph) for urban commuting, and an Unleashed Off-Road Mode for private trails.

The recommended rider height is between 5'1" ~ 6'5". With a seat height of 31 inches, it is suitable for adults.

The 72V platform is the gold standard for high-performance e-motos. It delivers higher top speeds (50 MPH), faster acceleration, and stays cooler under heavy load than lower voltage systems.

Thanks to our fast-charging technology, you can hit 80% charge in just 2.5 hours and 100% in 5–6 hours—getting you back on the road twice as fast as standard chargers.

This "Mullet" setup is used in professional motocross. The larger 19" front wheel rolls over obstacles easily, while the 17" rear provides better torque and snappier acceleration.

Our brushless hub motor is virtually maintenance-free. There are no chains to lube or gears to wear down inside the motor, making it much simpler to own than mid-drive bikes.

It arrives 85% pre-assembled. It's very easy to set up, and a QR code on the display links directly to a step-by-step assembly video.
