Feature Highlights
A 6500W peak motor with 245 N.m of peak torque that pushes G300 Pro to a top speed of 50 mph. From technical climbs to wide open fire roads, the acceleration hits hard and stays smooth.
Powered by a 72V 30Ah removable lithium pack good for up to 70 miles on a single charge. It refills to 80% in just 2.5 hours so you can spend less time waiting and more time sending it.
Adjustable front fork and rear shock dial in your ride. They soak up rocks, roots, and hard landings while keeping the wheels planted.
Five modes to match your ride, from mellow to wide open.
Class 1/2: 13 mph
Class 3/4: 25 mph
Class 5 Off‑Road: Up to 50 mph
Nineteen inch front and seventeen inch rear knobbies with a 70/100 footprint. Deep tread and aggressive side bite give you the grip to lean hard and trust every corner.
Oversized rotors and hydraulic stoppers deliver serious braking muscle. Confident and predictable, whether you're on pavement or loose dirt.
A full color LCD dashboard keeps your speed, remaining range, and trip data clear without overcomplicating things. Just glance down and you know exactly where you stand.
A 2000 lumen triple LED bar turns dark trails into a legit excuse to stay out past sunset. The beam throws wide and far enough that you won't be guessing what's around the next bend.
An integrated brake light and sequential amber turn signals keep your intentions obvious to anyone riding behind you. Visibility in low light and mixed traffic is never an afterthought.
More torque. More range. More freedom.
