FOREWORD
Dear users,
thank you for purchasing a CRUSSIS e-bike! We appreciate you choosing our product.
For proper operation of the CRUSSIS e-bike, read the product information carefully be-
fore using it. In this manual we inform you about all the details related to the use of the
e-bike (including the installation of the device, settings and normal use of the display).
This manual will also help you solve any ambiguities and problems.
CRUSSIS ELECTROBIKES s.r.o wishes you many beautiful and safe kilometers on the
new e-bike.

WHAT IS AN E-BIKE?
It is a classic bicycle that is equipped with an electric motor. This can be located in the centre, rear
or front hub. The maximum assist speed is limited to 25 km/h and this limitation corresponds to the
European standard EN 15194-1 (the electric motor is switched offwhen exceeding this speed and
switches on as soon as the speed falls below this limit). Furthermore, the bike is equipped with a
battery that can be placed in the frame or on the rear rack. The most important parameters of the
battery are voltage and capacity. The higher the values, the greater the range of the e-bike. Current-
ly, lithium-ion (Li-ion) batteries are the most commonly used. The advantage of these batteries is
mainly in their low weight and long service life. It is important to keep the battery regularly rechar-
ged to prolong its life. The communication between the individual electrical components is provided
by a control unit that evaluates the data from the individual sensors, according to which it controls
the performance of the electric motor. Operation of the electric motor is provided by a control panel
which provides information on battery status, support level and remaining range. Time, speed and
distance travelled are standard on most displays. The motor function is activated by pedalling, which
is sensed by a special sensor located in the pedal centre. So you have to keep pedaling the e-bike,
the motor only helps you. The pedalling sensor is responsible for informing the control unit whether
the rider has started or stopped pedalling and informs about the pedalling frequency. This function
is taken care of by either a magnetic waist sensor or a torsion sensor. The magnetic waist sensor is a
basic sensor that works on the magnetic principle. This sensor, which is installed on the center axis,
checks the pedaling frequency. Activation of the sensor by back pedalling is impossible due to the
magnets being out of phase. Torsion sensors are used on more expensive sports bikes. Compared
to magnetic sensors, they provide information about both the frequency of pedalling and the force
exerted on the pedal. A torsion sensor is ideal for off-road riding where there are frequent changes
in pedaling frequency. If we need to pedal with more force, the motor will immediately help us with
more power. On the other hand, when riding downhill, when less pedal pressure is applied, the mo-
tor function is reduced, thus saving battery power. You can set the e-bike in motion using the control
button , which is located on the display controller, but only up to the maximum speed limit, i.e.
6km/h (used to assist walking). On an electric bicycle that complies with the European standard
