Video Review

Written Review

The Green Bike Electric Motion Big Dog Off Road is a well rounded folding electric bike with front and rear suspension suspension, hydraulic disc brakes, a powerful motor and huge battery.

Power — 750 nominal watts, 1,200 peak watts

The Green Bike Electric Motion Big Dog Off Road electric bike has a powerful Bafang hub motor with 750 nominal watts of power and 1,200 watts of peak power and 80 Newton meters of torque. This is a powerful motor, but more than that, the motor controller provides some of the smoothest acceleration we’ve seen to date.

Speed  — 28 mph

The Green Bike Electric Motion Big Dog Off Road electric bike has a top speed of around 22 mph out of the box, which can be reached using the throttle or pedal assist, making this a class 3 electric bike and therefore not legal to ride in some areas. The top speed can be increased to 28 mph with the pedal assist for some serious racing days.

Battery and Range — 48 volt 15.9 ah, 50 miles

The Green Bike Electric Motion Big Dog Off Road electric bike runs on a 48 volt system and has a 15.9 ah battery for an estimated max range of 50 miles with pedal assist. The battery is located behind the seat post, which does make the Big Dog Off Road a bit back heavy since the motor is also in the back wheel. The battery can be removed for charging and storage. 

Pedal assist sensor — Cadence sensor

The Green Bike Electric Motion Big Dog Off Road electric bike is equipped with a cadence sensor that measures the rotation of the cranks. Like most cadence sensors, there is some delay from the time the rider starts and stops pedaling to the time the motor activates and deactivates.

Display — LCD

The Green Bike Electric Motion Big Dog Off Road electric bike display is located on the center  of the handlebars with plenty of electronic feedback including speed, distance, battery level, wattage output and more.

Frame and weight — 6061 Aluminum alloy, 60 pounds

The Green Bike Electric Motion Big Dog Off Road electric bike one frame size and five different colors —Black/Orange, White/White, Black/Gold, Black/Red and Black/Silver — with a curb weight of nearly 60 pounds. This is a little heavier than average for a folding electric bike, but much of the weight comes from the full suspension setup, powerful motor and much larger than average battery.

Suspension —  Mozo, 140 mm of travel

The Green Bike Electric Motion Big Dog Off Road electric bike has a Mozo suspension that offers 140 mm of travel. It also has a rear suspension with approximately 30 mm of travel to help smooth out the ride even more.

Gearing — Shimano, 7 speed

The Green Bike Electric Motion Big Dog Off Road electric bike has a Shimano Altus derailleur with a 7-speed cassette. It uses a Shimano trigger shifters on the right side of the handlebars.

Brakes —  Hydraulic disc

The Green Bike Electric Motion Big Dog Off Road electric bike has hydraulic disc brakes in the front and rear with 160 mm rotors. These brakes offer ample stopping power and the brake levers are equipped with motor inhibitors, which instantly cut power to the motor whenever the brake levers are depressed.

Warranty — 1 year comprehensive

The Green Bike Electric Motion Big Dog Off Road electric bike has a 1 year comprehensive warranty.

Price — Starting at $1,999

Starting at $1,999, the Green Bike Electric Motion Big Dog Off Road electric bike is towards the top end of the affordable price range, but does offer some serious power, range and riding comfort. Also, Green Bike Electric Motion offers free shipping anywhere in the U.S., which is a nice savings. 

Who’s it for —  Those who need power and range but have limited space

This feels like a good choice for those who need the power, range and comfort of a full size electric bike, but don’t quite have the space to store a full size bike. The Big Dog Off Road is a compact frame, but because of the geometry and specifically the handlebars, it feels more like riding a full size electric bike. Also, this will be a good choice for those who plan to carry extra cargo, and/or have steep hills in their area. As far as folders go, the Big Dog Off Road is one of the most powerful, and has one of the biggest batteries around.
