What is an electric bike?
It is a conventional bicycle equipped with an electric motor. The motor can be located in the cen-
ter, rear, or front hub. The electric motor may have a power not exceeding 250 W. The maximum
assistance speed is limited to 25 km/h, and this limitation corresponds to the European standard
EN 15194-1 (the electric motor turns offwhen this speed is exceeded and turns on again once the
speed drops below this threshold). Additionally, the bike is equipped with a battery, which can be
placed in the frame or on the rear carrier. The most critical parameters of the battery are voltage
and capacity. Higher values lead to an increased electric bike range. Currently, the most common-
ly used batteries are lithium-ion (Li-ion) batteries. The advantage of these batteries lies mainly in
their low weight and long lifespan. Regular charging of the battery is important to extend its li-
fespan. Communication between individual electrical components is managed by a control unit,
which evaluates data from various sensors to regulate the electric motor's power output accor-
dingly. The operation of the electric motor is facilitated through a control panel, which provides
information about the battery status, assistance level, and remaining range. Most displays also in-
clude information about the time, speed, and distance covered. The motor's function is activated
by pedaling, detected by a specialized sensor positioned in the pedal area. On an electric bike, you
must continuously pedal, and the motor simply assists you. The pedaling sensor is responsible for
informing the control unit whether the rider has started or stopped pedaling, and it reports pe-
daling frequency. This function is managed by either a magnetic strip sensor or a torque sensor.
The magnetic strip sensor is a basic sensor that operates on a magnetic principle. Installed on the
bottom bracket, this sensor monitors pedaling frequency. Activation of the pedaling sensor while
pedaling backward is not possible due to magnet phasing. Torque sensors are used in more expen-
sive, sporty bikes. Unlike magnetic sensors, they provide information about both pedaling frequen-
cy and the force applied to the pedal. A torque sensor is ideal for off-road riding, where pedaling
frequency frequently changes. When greater force is needed while pedaling, the motor provides
more power instantly. Conversely, when riding downhill and applying less pressure to the pedal,
the motor's function is limited, conserving battery energy. You can initiate movement on the electric
bike using the control button located on the display controller, but only up to the maximum
allowed speed of 6 km/h (used for assistance while walking). An electric bike that meets the Europe
an standard EN 15194-1 is legally regarded as a regular bicycle on public roads. This means you can
ride on bike paths, do not require a driver's license, and helmets are mandatory only for individu-
als under the age of 18. We recommend the use of cycling helmets for all users regardless of age.
