WHAT IS E-BIKE?
It is bike equipped with electromotor. Motor can be placed in the middle, rear or front hub. Motor can
have output up to 250 W. Maximum speed is limited to 25 km/h (after reaching max.speed the motor
will turn off and will turn on after the speed is lower than 25 km/h). In addition the bike is equipped with
battery that can be integrated in frame or placed on rear rack. The most important parameters of the
battery are voltage and capacity.The higher the values are, the longer is the distance range. Currently,
the most used batteries are lithium ion (Li-ion). The advantages of these batteries are mainly low
weight and long life. It is important to regularly charge the battery to extend battery life.
Communication between the individual electrical components is provided by a control unit, which
evaluates the data from the individual sensors, according to which it controls the power of the electric
motor. The operation of the electric motor is ensured by the control panel with information on battery
status, support level and remaining range. Most displays show the time, speed and distance traveled.
The motor function is activated by pedaling, which is detected by a special sensor located in the pedal
center. So you still have to pedal on the electric bike, the engine only helps you. The pedal sensor is
responsible for informing the control unit whether the rider has started or stopped pedaling and informs
about the pedaling frequency. The sensor is either magnetic sensor or a torsion sensor. Magnetic
sensor is a basic sensor, which works on the magnetic principle. This sensor, which is installed on the
center axis, monitors pedaling frequency. Activation of the sensor by peddaling back is impossible due
to the phasing of the magnets. Torsion sensors are used on more expensive sports bikes. In contrast
to magnetic sensors, they inform both about pedaling frequency and the force exerted on the pedal.
The torsion sensor is ideal for off-road riding, when there are frequent changes in the pedaling
frequency. If we need to pedal with more force, the engine gives us will immediately help with greater
performance. On the other hand, when driving downhill, when there is less pressure on the pedal, the
motor function is limited, thus saving battery power.
You can move the E-bike with button, but only to maximum speed of 6km/h (e.g walking
assistance).
The electric bicycle, which with its properties corresponds to the European standard EN 15194-1, is in
terms of law on road traffic is seen as a normal bicycle. That is, you can ride on on cycle paths, you do
not need a driver's license and a helmet is only mandatory until the age of 18. We still recommend to
use helmet regarding the age. (Every state has different law regarding e-bikes, always ask about your
local laws and ragulations).
