Double the traction. Double the fun. The FREESKY Ranger Air M-540 packs dual hub motors—1750W + 1750W peak (up to 200 N·m combined)—with a high-capacity 48V 25Ah battery for huge torque and range. Cruise up to 38 mph (PAS/throttle, where legal) and ride ~60–95 miles per charge in single-motor mode (about 40–60 miles in AWD). A step-thru frame, 4-piston hydraulic brakes, and 26×4.0" fat tires make it confident on city streets, sand, snow, and trails.
