3. USE OF AN EBIKE
3.1 Change speeds indexed
Your ebike has 6 gears, with a derailleur (6 sprockets) and a gear lever.
v 1 sprocket of 14 teeth (great development) that allows you, in easy congurations (downhill, at, etc),
to increase your speed ;
v3 intermediates sprockets of 16, 18, 21 teeth to use in a normal situation ;
v2 sprockets « small development » to 24 et 28 teeth for tough hills and starts.
The twist grip gear lever is on the right of the handlebar, operate it to select one of 6 preset positions. Turn
down to «descend» the gears (6-1) and turn upward to «mount» the gears (1-6).
3.2 Change speeds electronic
Your bike is equipped with 4 electronic assists:
1) Assistance set at 6 km/h that lets you start effortlessly. We must hold down the button 6km/h and
this starts your ebike without pedaling up to the speed of 6km/h;
2) LOW (on the left) = economic position. In this position your ebike uses less power;
3) MED (centre) = average assistance position;
4) HIGH (on the right) = maximum assistance. In this position your ebike provides the greatest
assistance, but also consumes the most energy.
To select assistance (L, M, H), press the «Mode» button.
The assistance selector is located on the left side of the handlebar below the button «ON / OFF».
«MODE» button. Assistance set at 6 km/h.

3.3 The battery meter
This gauge is on the display with the assistance selector.
Load indicator.
When switched on the differents the lights of the display successively light for a reading test, and stabilized
thereafter. Located on the left side of the handlebar, all gauge / selector is in range of your view. Initially with
a charged battery, all LEDs of the gauge are red. You can control the remaining energy and adapt your pace
and your assistance mode.
3.4 The electric assistance
3.4.1 Operation
Your ebike is a bike with electric assistance: it is equipped with an electric motor in the rear wheel. This
engine starts automatically (if the display is on and the battery charged) when you pedal and only when you
pedal.
The assistance is provided by an electromagnetic sensor that cuts power to the motor when the pedal stops
rotating.
The motor also switches off when:
• You press one of the two brakes;
• You reach the speed limit of 25 km / h.
This principle allows the engine to give you full power when you need it and make «energy savings» when
you’re going downhill or pedaling on a at road.
This energy management allows to offer a greater autonomy. These functions and energy management are
performed by an electronic box or «controller».
r
weinForM you that when on or oFF the assistance May result in acceleration or deceleration in spurts.

Manual CT26-15 - LFB

3.4.2 Performances
The rate of assistance of your bike is limited to 25 km / h.
At this speed the motor switches off automatically.
The autonomy of your ebike depends on several parameters:
vThe carrying weight:
The performance of your bike are given for an average load of 75 kg.
vThe outside temperature:
Performance is given for an outer temperature of about 20 ° C. Below this temperature performance
decreases. However, this decline is really signicant below 5 ° C.
vThe wear of battery:
Your battery is designed to deliver you stable performances for 600 charge cycles (or an average use of 3
years). After these 600 cycles, it is still operational, but its performance and therefore your range, decrease
proportionately.
vBut above all the autonomy depends on the nature of your journey:
The theoretical range of 45-55 km is for a near-continuous sollicitation of the engine on a at surface or
slightly up hill (10-20% of slop). If your course is at and includes a percentage of down hill (even minor),
your range is enhanced and can go up to 65 km. If you mount slop of more than 5% (the engine «suffers»
above 8% slop), your autonomy may decrease proportionally.
3.4.3 Technical specications of the assistance system
Motor: Brushless type - 250 watts
Battery: Lithium Ion 37V - 10AH - Life cycle: 600 full charge / discharge cycles under normal load condition
Autonomy: 55 km for 10Ah battery
(For someone of 75Kg with the ECO assist level).
3.4.4 Starting and the locking of the battery
The starting and stopping of the battery are controlled using the button «ON / OFF» of the display on the
handlebar.
