About US
Rattan was founded on the belief that the company does not have to compromise to
create great products at great prices. We are a team specialized in the manufacture of
electric bicycles for more than 10 years, and the goal of Ratan is to develop the latest
technology and affordable electric bicycle for all our friends.
We hope to pass a positive attitude towards life for all through our products. There is
much to be gained from traveling and seeing the world. We must all embrace at least a
walkthrough. However, let's not forget the ultimate goal; in wise words for T.S. Elliott, "We
will not stop exploring, and the end of all our explorations will be to get where we started
and find out the place for the first time." Now, ride your bike and let's go for a trip! Because
you will not know how beautiful the world is before you go out. After that, you will find that
we do not sell you a wonderful bike but a wonderful scenery along the mild.

What is I·PAS?
Intelligent power assist system (I·PAS) is patented technology of Rattan.
Featured with energy conservation and rechargeable.

This parameter is related to the meter display speed and needs to be entered correctly;
P07: Speed gauge magnetic steel number: Range 1-100.
This parameter is related to the meter display speed and needs to be entered correctly.
If it is an ordinary hub motor, the number of magnetic steel is input directly.
If it is a high-speed motor, it is also necessary to calculate the deceleration ratio, and the input data = the
number of magnetic steel × deceleration ratio.
For example: number of motor magnets 20, deceleration ratio 4.3: input data is: 86 = 20 × 4.3.
P08: Speed limit: Agreement No. 2 range 0-100km / H, 100 means no speed limit.
5S protocol 0-41km / H;
The input data here represents the maximum operating speed of the vehicle: for example, input 25,
indicating that the maximum operating speed of the vehicle will not exceed 25km/h; The drive speed is
maintained at the set value,

Error: ± 1km/h; (The speed limit for power and turning is equal).
Note: The value here is based on kilometers.
When the unit setting is converted from kilometers to miles, the speed value of the display interface
automatically converts to the correct mile value, but the speed limit value data set at this menu under the
mile interface is not converted. Is inconsistent with the actual speed limit of the mile speed.
P09: zero start, non-zero start setting, 0: zero start; 1: Non-zero start.
P10: The drive mode is set to 0: Power Drive (how much power is output is determined by the power file
bit and the switch is invalid at this time).

（4）Key Introduction：
The specific combination of keys is as follows
Press the button to use the brief, Key operation is divided into short press, long press,
and combination key length press Short press is used for rapid/frequent operations, such
as the specific key combination position as follows;
1. When riding, if you want to modify the power/speed state that through short pressing to
or
2. Toggle display data for multi-function areas during cycling, short click
Single key length is mainly used to switch the mode / switch state.
Composite keys (long presses) are used to set parameters because the operation is complex,
which can reduce errors
(Short press does not make the composite key, because it is easy to trigger mistakenly, so it is too
difficult to do）.
3. Specific operational explanations:
Modify the power ratio / power state, let’s say the current is power mode.
Short press Help + 1
Short press Help - 1

Toggle speed display
Long press, + Toggle speed display
Set / Disable 6Km/h Cruise, Switch Headlight, ODO Clear Zero
Static state of vehicles，long press will enter 6KM/h cruise mode.
Let go of cruise mode; long press Turn the lights on and off.
P16Menu Interface，long press five seconds，ODO clear zero.
Switching liquid crystal display [LCD]
If the current display is working，long press will turn off the screen, instead
turn on the screen
Toggle multi-function display area content
Short press to Can switch the value of the multifunction display area.

Set Parameters
Long press + will enter the parameter-setting interface. Parameters that can be set include,
Wheel diameter (in: inches), number of magnetic steel, liquid crystal brightness, low pressure points,
etc.(see settings: P01-P20).
Under Settings Interface，Can be short press or Set the value to perform a minimum-
precision unit value operation，you can also long press or Continuous Fast Modify
Parameters：
Short press Switch to Next Parameter；Exit settings and save parameters. If not operated, the
modified parameters will automatically exit and be saved after 8 seconds.
Note: Due to company product upgrades, product content will differ
from specifications, but will not affect your normal use.
