• Built for All Terrain: The 26-inch fat tires are ready for anything—mud, sand, snow, gravel, you name it. They also add extra comfort and stability, which makes off-road riding feel more like floating than bouncing.

• Hydraulic Brakes = Confidence: When you’re riding something this powerful, good brakes are essential. The M-520 Pro's hydraulic braking system gives you smooth, reliable stopping power even on steep descents or in wet conditions.

• Solid Build, Heavyweight Ride: At 75 lbs, this isn’t a light bike—but the trade-off is serious durability and a 300-lb cargo capacity. Whether you're a larger rider or planning to haul gear, the frame and motor won’t let you down.

• High-Speed Class 3 Performance: With top speeds between 25–28 mph, this bike qualifies as Class 3 in most areas—great for those looking to legally and confidently zip through traffic or trail systems where those speeds are permitted.
