Dear Cuomers,
Thank you for purchasing a ROCKRIDER electrically-assied bike.
We invite you to read the inruction manual to get the mo out of your e-ST900 bike.
Never forget that an electrically-assied bike is not a moped. It needs your help to go further,
faer and longer.
We sugge that you learn how to use your electrically-assied bike in an open area in order
to get used to the feel of the motor kicking in and thus ensure optimum control of your bicycle.
An electrically assied bicycle is heavier than a conventional bicycle (unloaded weight of the
ROCKRIDER e-ST900 is 21.9 kg for the small version, 22.1 kg for the medium, 22.2 kg for
the large version and 22.3 kg for the extra large version). Without power assiance, pedalling
can be more dicult.
You mu always make sure you are capable of riding the entire journey without assiance,
in case your battery runs at.
Here is what you need to do to get the mo out of your ROCKRIDER power-assied bike.
Important, this inruction manual only applies to the electrical characteriics of
your bicycle.
You should refer to the user guides for all our bicycles that come with this document
and that are also present on our www.supportdecathlon.com website or on reque
in our DECATHLON ores.

How to get the mo from your PAB
1,0 - 1,8 bar
1. The bike will operate better and more eciently with
tyres inated between 1.0 and 1.8 bar
< 3 bar
pfff
2. Under-inated tyres are more prone to punctures
< 6 months
3. The battery mu be fully charged at lea once every
6 months 4. cold weather reduces battery life
5. Overloading the bicycle will reduce the battery life 6. Battery life will drop when cycling uphill
7. Remove the battery before conducting any mainte-
nance work
> mode 1 < mode 1
8. It is advisable to reduce the power assiance mode
when the battery charge is low

General operation of the electrical assiance
The power-assied bike can be used with or without assiance by pressing the ON/OFF button or altering the modes 0-1-2-3-4. The selectable
0-1-2-3-4 assiance modes on the «D» display screen allow you to choose a power assi level in addition to the eort provided. Power assiance
will only work if you are pedalling, with a selected mode other than 0. Assiance cuts o when the speed is above 25km/h. In case of intensive use
and in exceptional climatic conditions, assiance may be cut o to safeguard the whole syem.
The power supplied is calculated by the motorised unit controller «C» based on your pedalling rate and the force applied to the pedals. The control-
ler «C» will provide more or less power depending on the mode selected and the force applied.
Power assiance does not kick in or shuts down in the following situations:
- The speed is above 25km/h
- You’re not pedalling
- The remaining battery charge is not sucient
- »0» is the power assiance mode selected
- When the control screen is o

Pederian assiance mode: When you have to push your bike up a hill, this mode is ideal as you
won’t notice the weight of the bike! N.B.: Do not use this mode when you are on the bike. This
mode arts and continues to be applied while the button is held down (when not in mode 0).The

MOTOR
Motor «C» of your power-assied bike is a brushless-type motor with mechanical reduction, allowing you to have high torque and less resiance
(quieter motor). So motor noise in use does not exceed 70 db. The power of the motor is limited to 250 W maximum.
BATTERY AND CHARGER
Battery properties and warranty
Voltage: 100 V, 240 V maximum.All batteries in our electric bikes use Lithium-Ion cell technology and have no memory eect. (the battery can be
