FAQs
Yes! Thanks to our high-performance 60V 6000W mid-drive motor and precision-tuned controller, the G300se Ultra can exceed 44 MPH under optimal conditions. Because it delivers Instant Torque, we recommend that new riders start in a lower speed mode to get a feel for the power.
Unlike hub motors found in cheaper models, a mid-drive motor is positioned in the center of the frame. This creates perfect weight distribution and allows the motor to leverage the bike's gear ratio, multiplying the torque to a massive 240 N.m. It provides superior balance for Off-road maneuvers and much better climbing ability on steep trails.
The G300se Ultra is designed for Long Range exploration. You can expect 56 to 65 miles of range depending on rider weight, terrain, and speed settings. It’s built to keep you shredding all day without needing to head back to the charger.
Using our included smart charger, a full charge from 0% to 100% takes approximately 6-8 hours. Many riders find it easiest to charge overnight so the bike is ready for a full day of riding the next morning.
Absolutely. Our 60V 31Ah lithium battery is housed in a reinforced casing within the frame to protect it from impacts. It also features an advanced Battery Management System (BMS) that prevents overcharging, overheating, and short circuits, ensuring maximum safety during intense E-moto sessions.
This bike is built for versatility. With a 31.9"" seat height, it comfortably fits riders ranging from 4'1"" to 6'1"". The high-strength frame supports a payload of up to 350 lbs, making it a rugged choice for both teens and adults.
The G300se Ultra has an IPX5 waterproof rating. This means it is resistant to splashes, rain, and mud. You can confidently ride through puddles and wet trails, though we do not recommend submerging the bike in deep water or using high-pressure power washers directly on electronic components.
Safety is our priority. We’ve equipped this bike with professional hydraulic brakes and oversized 190mm rotors. This setup provides significantly more stopping power and better heat dissipation than mechanical brakes, allowing you to ""stop on a dime"" even from top speeds.
The G300se Ultra is designed as an Electric Dirt Bike for off-road use on private property, designated trails, and OHV (Off-Highway Vehicle) areas. Laws regarding electric motorcycles on public streets vary by state and city; we recommend checking your local DMV regulations.
One of the best parts about an electric E-moto is the low maintenance! There are no oil changes, spark plugs, or carburetors to worry about. You only need to perform basic checks: keep the chain lubricated, monitor tire pressure, and check brake pad wear periodically.
We ship directly from our US-based warehouse. The bike arrives approximately 85% pre-assembled. You will only need to install the front wheel, handlebars, and footpegs. We provide all necessary tools and a step-by-step video guide—most riders are ready to go in under 45 minutes!
We offer dedicated US-based customer support. Whether you need technical advice, replacement parts, or warranty service, our team of experts is just an email or phone call away.
