4 ELECTRICAL SYSTEM

4.1. Description of the electrical system

The components of FitNord electric mountain bicycles have been designed to make
riding easy, efficient and effortless. Your bicycle recognises the rider pedalling and
assists in relation to the selected level of assistance.
In models that are equipped with a motion sensor (Flow, Agile Ava 200, Ranger 200,
Ava 300 and Venture 300), the sensor will interpret motion from the motion sensor
located on the crank arm and assist in relation to the pedalling rhythm.
In models that are equipped with a momentum sensor (Flow +, Agile +, Ranger 300
and Rumble 300), the system identifies the power with the help of the momentum
sensor located on the crank arm. The sensor interprets the torque produced at the
crank arm by the pedalling rider and generates assistance power in relation to this.
The electric assistance system of your bicycle consists of the following components:

4.2. Battery

The lithium-ion batteries of FitNord electric bicycles are among the most powerful
ones on the market. They use efficient and stable Samsung and LG cells. The struc-
ture that consists of high-capacity cells ensures a streamlined and lightweight bat-
tery without compromising on capacity. In addition to this, many of our models have
a built-in USB port, which you can use to charge your mobile phone or other small
electric devices while using the bicycle.
The battery is removed from the frame with a key. Before removing the battery in
Flow and Agile models, the protective cover under the crank arm set, which prevents
dirt and moisture accessing the battery space, must also be removed. The battery
can be charged either attached or removed from the bicycle. Before charging, please
read the battery's safety instructions in Section 2.2.
To ensure the maximal service life of the battery in terms of its charge level, it is
recommended to avoid emptying the battery entirely or overcharging it. In the long
term, they can wear the cells' storage capacity and gradually weaken the battery
capacity. Therefore, aim to keep the battery charging time under control. For basic
models, this amounts to a charging time of 4-5 hours from empty to full, and in case
of large-capacity models, approximately 6-7 hours. It is optimal for the battery to
be kept between 20-80% charged.
