Foreword
What is a Pedelec?
It is legally considered as a conventional bicycle, whereas the
rider is enjoying some electrical power assistance based on
the human power brought up by the rider. Just ride like on a
conventional bike, the system will add some extra power. It feels
like having tailwind or a continuous descending ride.
In European Countries the assistance is legally limited to 250W
nominal power and a max. speed of 25km/h. Riding faster than
that is possible, but there will be no assistance when riding
faster than 25km/h.
A Pedelec is sometimes called EPAC, Light-Electric-Vehicle (LEV), Hybrid Bicycle or eBike or
electric bicycle with Pedal-Assisted-System (PAS).
Dear customer,
congratulations on your new electric bicycle purchase. The bike is equipped with the SR SUNTOUR
SRS-SY-pedelec drive unit with a rechargeable Lithium-Ion battery, a display and user interface,
a torque sensor, a controller and a brushless front hub motor..
To make your ride smooth, safe and fun please take some time to read this manual carefully. It
contains information on the proper care of the drive unit of your electric bicycle and advice on
how to achieve the bikes’and batteries’ full lifespan.
In case of any enquiries not covered by this manual please contact your local dealer.
Enjoy the riding!

1.
The system must be switched off by
pressing the “on/o”-button on the dis-
play.
2.
Insert the key of the battery lock into
the upper battery holder, turn the key
counter-clockwise and keep it so while
you push the battery out to the left side

3. After you have pushed out the battery a
little bit to the side (depending on the
frame design) the handle can be swinged
out for an easy and safe handling.
4. Pull the battery out upwards.
5.
Connect the charger adaptor to the
