GreenBike Big Dog 2021 Extreme Electric Bike

About the GreenBike Big Dog Extreme Electric Bike

The Big Dog Extreme is the epitome of power and modern design. This high-quality electric bike is an ideal choice for those who want a hardcore bike that can be used on a variety of terrains. It has 2 different modes, including speed sensor pedal assist and thumb throttle, which allow for both on and off-road riding, as well as a 750W motor to enable stronger power assist.

The Big Dog Extreme’s powerful battery is hidden within its aluminum frame and is capable of delivering up to 50 miles per charge. The 4.0” tires on the Big Dog Extreme provide improved grip and traction as well as maximizing the contact surface and minimizing pressure between the bike and the ground. This enables even snowy trails to be navigated safely. It has an intelligent display that shows current battery power, speed, pedal assist level and travel distance, keeping you informed throughout your ride.
