Cautions and Safety

General Cautions and Warnings

The Rungu Dualie is an electric vehicle that you can ride like a bicycle with the added benefit of more
stability on soft ground and difficult terrain.

For all bicycle riding cautions and warnings, refer to the

All-Purpose Bicycle Manual

available as an

electronic link on the list of documentation that came with your Dualie. If you cannot find your copy of
the All-Purpose Bicycle Manual, email

[email protected]

and request an electronic copy.

WARNING: THE DUALIE HAS A TIE-ROD THAT CONNECTS THE TWO FRONT FORKS. DO NOT

USE THE TIE-ROD TO LIFT DUALIE. 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 DUALIE.
