the battery by switching the key
to the ON position.
The 4 green LEDs located on top of
the battery indicate its capacity.
Turn on the display unit that is on the
handlebars (see 1.3).Select your desired assistance level and begin to pedal. You’ll
find that the engine starts as soon as you start pedaling.

5
When you use the brakes, the contactor located within these brakes immediately halt
the engine’s assistance.
The left brakelever controls the front brake. the right
brake lever controls the rear brake.
You can also use the bike without the electric
assistance mode by turning off the battery (switch button on «O» or by adjusting the
assistance level on 0). The engine
will then feature zero resistance: you’ll be freewheeling. Select the appropriate gear
by activating the 6-speed gear lever.
2.2 Adjusting the height of the seat
Unlock the lever (OPEN), adjust the seat height to
the desired position without ever exceeding the
mark carved onto the seat’s tube, lock the
lever(LOCK).
The seat’s height must be set so that yourleg is
stretched out when the corresponding pedal is in
the lower position.
2.3 Propping the bike upon its stand
Your bike is equipped with a main
stand. Always prop up the bike on its
stand on a flat and stable ground surface.

3.2 Charging the battery
Never let a battery be charged unattended.
The battery’s autonomy is indicated with the 4 green LED lights located on top of the
battery, and also on the display unit located on the handlebars (see 1.3 indicator 8).
Your battery must be charged in an ambient temperature, on a non-flammable and
dry surface, away from any sources of heat, humidity or flammable materials. Also, it
must not be covered.
Here are the steps to be followed when charging your battery:
Step 1
Turn the battery off. The LED lights will be off.
Step 2
Plug the charger (which is off) into the socket and then insert the
charger’s plug into the battery, which is also off.
Step 3
the charger’s LED indicators lit up in the following manner:
• The red LED lights will be on: the battery is being charged.
• The red LED light becomes green:
the battery is charged; you can unplug the charger. (B)
(A) (B)
It takes 3 - 6 hours for the battery to be fully charged when using the standard charger
that’s supplied with your bike.
3.3 Battery autonomy and lifespan
3.3.1 Autonomy
The bike's autonomy ranges from 40 to 120 kilometers, as it depends on many
different factors (degree of assistance used, topology, rider’s weight, frequent
stops/start-ups, hills, tyre pressure, etc…)
3.3.2 Battery
Your battery is just like a household battery. It contains a limited amount of energy,
which diminishes as it is being used. When the available autonomy no longer
corresponds with your needs, you will be able to obtain a new one from your dealer.

10
3.3.3 Maintenance
If you don’t use your bike for a period of time exceeding 2 months, store it in a
humidity-free area to protect the electronic components and make sure that the
battery is neither completely charged nor completely discharged (2 or 3 green LEDs lit
up)
3.4 Battery safety instructions
Your bike's battery is an electric component made up of chemical elements. For your
safety, it is imperative that you obey the following rules:
Note: Never store a completely discharged battery as it might result in permanent damage.
During the winter or long storage periods, it is recommended that you charge
the battery halfway every 2 months. Don’t forget to switch it off. Store your
battery at a temperature between 15° and 25°.
Always handle with great care
Always keep it away from children
Do not take it apart or hit, pierce or submerge it
Keep it away from temperatures exceeding 60°
Never create a connection between the contacts
located at the bottom of the battery
Never let the battery charge unattended
Never sleep near a battery that is charging
Only use the charger that came with your Velosolex
or that was supplied by your dealer
If your battery is damaged, do not use it and take it
back to your dealer as soon as possible

4. Safety and maintenance Recommendations
4.1 Safety recommendations
Helmet
For safe riding- use of a bicycle helmet.
Tyres
Inspect the wear of your tyres on a regular basis and verify the tyre pressure
at least once a month. Tyre pressure: 40-65 PSI depending on the weight of
the user.
Wheel-rims
Please care of the wheel-rims and a clear explanation of any danger of rim-wear.
Brakes
Please check all connections of the Disc Brakes before attempting to ride the
bicycle. Secure tightly the 2 bolts that hold the brake mechanism to the fork. Insert
the front wheel into the fork dropouts ensuring that the disc fits into the brake
mechanism between the enclosed brake pads. Secure the front wheel to the
bicycle by tightening the quick release mechanism and clamping the lever to the
closed position. Please refer to section 6 for further instruction on quick release
mechanisms. Next, attach the cable to the brake lever by inserting the cable end
into the cable end holder after the barrel adjuster and lock nut slots have been
aligned with the cable end holder. After the cable is secured to the lever, rotate the
barrel adjuster and lock nut so the slots no longer line up. Ensure the cable
housing seats appropriately into the end of the barrel adjuster and check for any
kinks or damage. Slide the exposed brake cable through the rotating rod/housing
stop located on the caliper body and seat the housing all the way into the same
stop. Insert the cable into the spring and spring boot. Next, slide the cable through
the cable anchor and pull all the slack out. Secure the cable in place by tightening
the bolts that comprise the anchor assembly. Some disc brakes will have a
centering devise while others are a free-floating mechanism. If your caliper body is
equipped with centering bolts, apply the brake lever after the cable has been
connected. While engaging the lever, tighten the centering bolts securely. This will
center the caliper body on the disc. Minor brake adjustment can be made via the
barrel cable adjusters which are located on each brake lever. To adjust, squeeze
the brake pads against the rim, loosen the lock nut, and turn the adjuster to pull
the brake pads closer to, or spread them away from the rim as required. Make
sure to inspect the wear of the front brake pads as well as the rear brake blocks. If
the brake action remains insufficient, despite your adjustment efforts using the
toothed wheel located next to the levers, contact your dealer so that these worn
out parts can be replaced.

12
Important : braking distance increases on humid or slippery ground
Saddle-post
Suitable covering and coil springs under the saddle if
a child-seat is fitted to prevent trapping of fingers.
Reflector
please regarding the positioning of reflectors
and lamps such that these are not obscured
when luggage is attached to the luggage carrier.
Gears
Like the chain, the freewheel must be kept clean and well lubricated. If the chain
has become worn and needs replacing, then it is likely that the freewheel will also
have become worn and should also be replaced. Take the chain off the freewheel
and rotate it with your hand. If you hear a grinding noise or the freewheel stops
suddenly after spinning it, it may need adjustment or replacement.
Carrier
Maximum authorized load: 25KG
This luggage carrier is not designed to pull a trailer.Don't install the child-seat on the
carrier.The bicycle may behave differently (particularly with regard to steering and
braking) when the luggage carrier is loaded, please attention. Please ensure that any
luggage fitted to the luggage carrier is securely fitted in accordance with the
manufacturer’s instructions and that there are no loose straps that can get caught in
any of the wheels. Please distribute luggage evenly between the two sides of the
luggage carrier.
Rack
The rack is able to hold a maximum, evenly balanced load of 10KG.
Signaling device
The bike is silent. In order to alert others as to your presence, you have an
approved signaling device: use it only when absolutely necessary, don’t abuse it!
