HappyRun G300 Pro Electric Dirt Bike

The HappyRun G300 Pro has a claimed top speed of 80 km/h (50 mph). This is above average for performance scooters (avg 72 km/h).

The manufacturer claims 113 km (70 mi) of range per charge. Real-world range will vary with rider weight, speed, terrain, and temperature.

The HappyRun G300 Pro delivers 6500 W (6.5 kW) of peak motor power.

The HappyRun G300 Pro is rated IPX5, which indicates splash resistance — light rain is fine, avoid puddles.

The HappyRun G300 Pro comes with a 36-month (3 years) manufacturer warranty.

The HappyRun G300 Pro has a seat height of 787 mm (31.0 in). The manufacturer suggests it suits riders roughly 154–196 cm tall.

The HappyRun G300 Pro is classified off-road only. It is not homologated for public roads, so riding it legally means private land or a designated off-road area. Rules vary by country and region — check yours before buying.

The HappyRun G300 Pro is equipped with a 2,160 Wh lithium-ion battery. This high-capacity pack supports the model’s 113 km advertised range under ideal conditions. Actual range varies based on terrain, throttle usage, and rider weight, so battery management is crucial for extended off-road sessions. No pedal-assist functionality means all range management comes from throttle input.

To maintain the G300 Pro’s battery, follow balanced charging cycles—avoid draining it below 20% or charging above 90% regularly. Store the battery at around 50% charge if leaving idle for more than two weeks. Clean contacts before and after rides to prevent corrosion. Adhere to manufacturer-recommended service intervals to preserve lifespan.
