The first is the Model E Ninebot released in 2013, whose success has generated $ 10 billion.

In 2014, the output of the Ninebot One is a success, the R & D Ninebot wanted to develop a Segway from the model E, accessible to young people at a price being 1/5 the price of the E model, 3000 yuan will be sold 1999 yuan. Contemplated with a weight less than 10 kg,

Of 8 "wheels with a folding system in order to facilitate its storage and transportation with the aid of a handle on its center of gravity.

Too bad that the idea of ​​the handle is abandoned

The goal is an intuitive driving experience with the ability to control with his legs, with the aim of having your hands free,

Unfortunately, the folding mechanism is complex, increases the weight and is expensive to produce.

In addition it reduces the reliability of the order by the legs.

This mechanism is not high enough and affect driving comfort, the mechanism is modified to be broken down into three branches.

The battery is also a source of disadvantage because it can not be folded

End of August 2014, the first prototype was completed.

The tests begin.

But the folding system therefore raises concerns of reliability, weight and safety.

Road tests show that the wheels 8 "will include well on a flat road but not on every road, the wheel diameter is too small and will be abandoned for a 10.5"

"80% of prototypes were shot" 😄😄

Battery :

Ninebot studied counterfeit batteries outputs on the market for the model E.

The counterfeit batteries quality problems can lead to the fall of the passenger, or the fire of the battery.

For these reasons, they designed a smart battery, allowing users to know exactly the state of health of the battery and the remaining capacity of the battery at any time and be able to identify the authenticity of battery, to prevent users from using a counterfeit battery.

Technology is combined with that of BMS SEGWAY

The team develops the intelligent features of the BMS system as the ThinkPad ThinkVantage: Users can view the serial number for each battery, the activation date, the number of charges, the remaining life of the battery by means of an application.

The tests, extreme, lasted 6 months.

And BMS cells are laser welded, the BMS is protected from shock and salt spray.

Battery test

Some were carried out in the combustion chamber,

Put in oven at 130 degrees Celsius

Struck with a hammer and a nail on the battery until it is fractured,

Diving one day and one night in the water ...

There was one twenty different design before marketing the Mini

These three models are different ...

In April 2015, 500 prototypes from the factory to complete 50 000 km of road testing.

Every evening, about twenty bugs readings are immediately solved.

The Mini was pushed to a cruising speed of 28km / h!

Then crash tests on a concrete wall, and the braking distance has reduced its speed 20km / h

La conception du Mini a durée 19 mois, soit 570 jours complets
