Cautions and Safety
General Cautions and Warnings
The Electric Juggernaut LE is an electric tricycle that you can ride like a bicycle with the added benefit of
more stability on soft ground.
Refer to the All Purpose Bicycle Manual available on the Rungu USB drive that ships with the Electric
Juggernaut to new customers or online at this link
2
.
WARNING: Being a tricycle, the Electric Juggernaut has a tie-rod that connects the two
front forks. DO NOT USE the tie-rod to lift the Rungu. The steering uses the tie rod as a hard stop so
the forks don’t rub against the front wheels. Grasping the tie rod when lifting WILL RESULT IN A
PINCH TO THE HAND AND FINGERS THAT MAY LEAD TO HAND OR FINGER INJURY. ONLY GRASP
PARTS OF THE FRAME OR SADDLE TO LIFT THE RUNGU.

Battery Safety (Brief Overview)
NOTE: If you ever suspect a battery problem, please contact Rungu Support immediately by email or
phone so we can go through the appropriate steps/procedures to make sure everything is okay with
the battery system.
At Standard Bearer Machines, safety is our number one concern. Standard Bearer Machines wants our
customers to enjoy an excellent product that will give those customers years of trouble-free operation.
As much effort as Standard Bearer Machines partner, Hi Power Cycles, makes to minimize the risk of
these state-of-the-art batteries, there are always safety concerns when it comes to Lithium batteries
that we want our customers to be aware of. All new portable electronics, including cell phones and
laptops, contain lithium batteries which have the same chemical properties, although bike batteries are
on a much bigger scale. Hi Power Cycles makes every effort to have the highest quality battery cells and
best battery protection (called a BMS or Battery Management
System) to minimize any risk associated with these high-power
batteries.
Hi Power Cycles has gone through extensive research and testing
to get the best electric bike batteries in the world. The battery
chemistry is the same that large car manufacturers (such as
Nissan) use in their vehicles. This state-of-the-art battery
chemistry is called Lithium Nickel Manganese Cobalt
(LiNiMnCoO2) or NMC for short. Hi Power Cycles feels that this is
the best overall combination of power, safety, performance, and
life span compared to the other options available.
Due to the nature of lithium cells, which have a lot of energy stored in a small package, there is always a
possibility this energy can be suddenly released and can cause fire and/or serious injury if not taken care
of immediately. With a state-of-the-art Battery Management System that is found on all of our battery
packs, the cells and pack are protected from failure. The only time a pack will fail will be a result of a
BMS failure and attempting to charge, short circuit, over discharge, or somehow puncture the battery
pack.
The main cause of failure in lithium batteries occurs during the charging portion, when cells can be
overcharged. This is the number one failure and can lead to batteries which vent and eventually release
all their energy at once (or can even cause the battery pack to ignite on fire). Due to a BMS failure, cells
can get out of balance and certain cells may become overcharged as a result. Therefore, Hi Power Cycles
always recommends monitoring the charging process in the extremely rare event something should
happen.
Caution: Charging on a concrete floor, such as in a garage, away from debris and material is always
recommended as a safety precaution.
