The G300 SE Ultra is compact in size and anything but compact in capability. A professional-grade mid-drive motor puts out 6000W of peak power and 240 Nm of torque, pushing the bike past 44 MPH with the kind of acceleration that makes it feel bigger than it is. Built for teens and adults who want a serious off-road machine without the full-size footprint, it pairs pro-grade suspension and heavy-duty brakes with a 60V 31Ah battery good for up to 65 miles — enough for a real day on the trail, not just a quick loop around the block.
\nCompact in size but massive in capability, it's the kind of bike that surprises people the first time they twist the throttle.
