Dear Cu󰘵omers,
Thank you for purchasing a B’TWIN electrically-assi󰘵ed bike. It will introduce you to the joys of travelling
on 2 wheels for your leisure, it will be the mo󰘵 practical and economical way for you to get around in
town and will allow you to burn calories to keep 󰘰t.
We invite you to read this in󰘵ruction manual to get the mo󰘵 out of your B’TWIN electrically-assi󰘵ed
bike.
Never forget that an electrically-assi󰘵ed bike is not a moped. It needs your help to go further, fa󰘵er and
longer.
We sugge󰘵 that you learn how to use your electrically-assi󰘵ed 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.
Only use sport mode for your 󰘰r󰘵 kilometres if you are sure that you are able to control your bike.
Here are the 10 commandments to get the be󰘵 use of your B’TWIN electrically-assi󰘵ed bicycle.
Electrically assi󰘵ed bicycles are heavier than classic pushbikes. Without assi󰘵ance, pedalling can be
harder.
You mu󰘵 always make sure you are capable of riding the entire journey without assi󰘵ance, in case your
battery runs 󰘱at.
Important, this in󰄋ruction manual only applies to the electrical characteri󰄋ics of your bicycle.
You mu󰄋 refer to the B’TWIN user guide and warranty in󰄋ructions that are shared by all of our
bikes and which are provided with this document. They can also be found on our website at
www.btwin.com or reque󰄋ed at our DECATHLON 󰄋ores.

10 be󰄋 practices for getting the mo󰄋 out of your electrically-assi󰄋ed bicycle.
1
You need to pedal to go further
23,5 ─ 6 bar
In order to improve battery life and e󰘲ciency, pump the tyres to
between 3.5 and 6 bar
3< 3 bar
pfff
Under-in󰘱ated tyres are more prone to punctures

20° 5°
cold weather reduces battery life
5
Overloading the bicycle will reduce the battery life
6
Battery life will drop when cycling uphill
< 3 months
7
The battery mu󰘵 be fully charged at lea󰘵 once every 3 months
8
Do not put your feet on either pedal of the bicycle when switching on
the power assi󰘵ance

General operation of the electrical assi󰄋ance
The electrically-assi󰘵ed bike can be used with or without assi󰘵ance by pressing the ON/OFF button. Always lock the battery
with the key when in use. The electrical assi󰘵ance will only operate if you pedal. The assi󰘵ance will switch o󰘯 the moment
either of the two brake levers is depressed or the speed reaches more than 25 km/h. It will then re󰘵art automatically when
below 23 km/h. In order to preserve battery life, the bike is equipped with a «power» limiter that limits assi󰘵ance when the
motor is under heavy 󰘵rain. During intensive use and in exceptional weather conditions, the assi󰘵ance may switch o󰘯 to
safeguard the entire sy󰘵em.
