Congratulations on purchasing a Rungu Dualie®

1

! You own the latest generation of the ultimate electric 

alternative to a Quad ATV for off-road utility and fun. Before you ride, 

please read the following 

instructions carefully

.   

Rungu Dualie uses the Bafang BBSHD mid-drive motor with a custom Rungu 52V (nominal voltage) input 
that generates more than 1.4kW of mechanical power for off-road use. You access the power by 
pedaling 

(“

Pedal Assist

”)

 or pressing the thumb throttle. In 

“Ped

al Assist

,” the 

Dualie senses when you 

start to pedal and engages the motor to assist your pedaling - 

you don’t have to use the throttle if you 

don’t want to

. The amount of power assist varies based on the power level you select as you ride. Unless 

you have ordered your Dualie with Class 1 or Class 2 reprogramming, we ship the Dualie configured with 
five selectable power levels starting with very little assistance up to full power, which is intended for use 
off-road only. The power settings are discussed below. 

Note: US Federal Law mandates a 750W/20 MPH limit for riding an e-bike on public roads without a 
license. Please check with your local government to ensure you follow all local laws and ordinances.
