Whether you’re tearing down a trail, navigating icy city streets, or cruising on sandy beaches, the fat tires make the M2 Pro one of the most versatile e-bikes available.
Braking & Suspension – Safety at High Speed
With speeds up to 36 MPH, stopping power and ride stability matter. The M2 Pro delivers with:
