Chapter I Introduction of Esway
The working principle of the two wheeled Scooter is based on the basic principle called
"dynamic stability" which is the automatic balance ability of the vehicle itself. After judging
body posture position with a built-in precision solid gyroscope, the vehicles electronic brain
works out proper instructions through a sophisticated and high-speed central
microprocessor, electric scooter will drive the motor to balance the vehicle.
As a new transporter, Esway is difficult to classify in the traditional way, some people
think that Esway should be a kind of double-wheeled Unicycle, while other people think it
should be classed as a power stand-up Scooter, with its uniaxial double design which is
different from the traditional biaxial double scooter, for official road regulations, this
transporter is called Electric Personal Assistive Mobility Device (EPAMD)
The vehicle is equipped with dual wheels; its width is as narrow as a normal adult
shoulder's width. It is 46.5KG (Li-ion battery) or 55KG (lead acid battery) operated. It is
not necessary to have a brake or throttle during driving. When the driver leans his body
forward, Esway will run forward, when the body is upright, it will stop. It uses the dynamic
balance principle, as the body moves to change the center of gravity so as to keep balance.
Just as the human body stands and leans forwards it can lose balance, but the body's natural
instinct will maintain balance, the dynamic stability replicates this. Esway uses the wheels
to replace the function of the feet, reproducing the high precision balance action of a human,
it is also cheap and convenient to use. The energy comes from two repeat charging BTM
batteries which are free from maintenance. If sufficient power is supplied to your battery,
the full charge capacity will last continuous for 5 hours driving, the driving range depends
on the way you drive and ground conditions, driving on grass and slopes will consume more
driving power.
