Congratulations on purchasing a Rungu Electric Juggernaut Mid-Drive Version
! You own the latest
generation of Rungu True e-ATVs for on-road and off-road access for adventure and fun. Before you ride
and make new tracks, please read the following instructions carefully.
Standard Bearer Machines, LLC (Standard Bearer Machines) thanks you for your purchase!
The Electric Juggernaut Mid-Drive Version (MDV) uses the Bafang BBSHD mid-drive motor with a custom
Rungu 52V (nominal voltage) supply to provide more than 1.5kW of power. You access the power by
pedaling ("Pedelec") or pressing the thumb throttle. As a "Pedelec," the MDV 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. The MDV
has five power levels starting with barely any assist to full power - intended for use off-road only. The
power settings are discussed in the power settings section 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 our kits or bicycles. By using the Electric Juggernaut, you are agreeing to
Standard Bearer Machines Terms and Conditions and the warnings and conditions of the Generic Bike
