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 “Pedal 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.
Standard Bearer Machines are not liable for those who choose not to follow their local laws.
CAUTION: STANDARD BEARER MACHINES WILL NOT BE HELD RESPONSIBLE FOR PEOPLE WHO CHOOSE
TO DISREGARD THE LAW!
WARNING: IMPORTANT- STANDARD BEARER MACHINES WILL NOT BE LIABLE FOR ANY DAMAGE OR
INJURY THAT MAY OCCUR DUE TO OPERATION OF YOUR DUALIE. BY USING THE DUALIE, YOU ARE
AGREEING TO STANDARD BEARER MACHINES TERMS AND CONDITIONS AND THE WARNINGS AND
CONDITIONS OF THE GENERIC BIKE MANUAL WHICH ARE INCLUDED WITH OTHER LINKS ON THE
MANUAL GUIDE THAT COMES WITH THIS PRODUCT.

or “Right”. This means that the brakes have been adjusted differently for each wheel –use the
labels to guide which wheel mounts on which side.
Note: The left side is considered the side with the brake rotors. The right side has the chain and
gearing.
