1. IMPORTANT INFORMATION
PEDALS: The pedals of the bike you have just received have a L and a R at the
extremity of the axis. The pedal with the R spins clockwise and has to be set up on the
right side; the pedal with the L spins the other way around (anti-clockwise).
DERAILLEUR: This bike requires a 20 hours running-in phase. You have to make it by
only using the medium speed and the central cassette during this time. If you use higher
or lower speeds during this running-in phase the bike chain may come out of the chain
ring.
BRAKES: The disc brakes also need a 20 hours running-in phase. At the beginning
they won’t be working 100% and there might be some frictions that will go away during
this phase. We recommend not to make any kind of adjustments because all the
components sent come a little tensed up to avoid readjustments just after the running-in
phase.

3. BIKE’S UNPACKING
Place the case upright. Open it from the top with your hands. Do not cut the box with a
knife or you could damage the bike. Turn the 4 box flaps outward and pull the bike up.
Put it on the ground without hitting it, otherwise the tips of the fork could bend, as the
front wheel has been removed.
Remove all the bike’s protections: from the frame, the controls and from the front wheel
axle.
Unscrew and remove the pedal.
If it's a mountain or a city bike, cut the straps which are holding the front wheel to the
frame and separate them.

4. INSTALLATION
4.1 MOUNTAIN AND CITY BIKES
We ship mountain and city bikes already assembled. You just have to place the front
wheel, screw the pedals and install the saddle (on some models it is already installed
too). If your bike has a basket, you should install it as well.
IMPORTANT: Do not use the bike before checking all components, especially brakes,
headset and wheels. View Settings.
4.1.1 FRONT WHEEL
4.1.1.1 MOUNTAIN BIKES
IMPORTANT: Do not loosen the axle nuts (see picture). The fastening system is by
wheel quick release. These nuts are tightening the bearings.
Pass the quick release system inside the axle, by putting it on the opposite side to the
disc, and screw the nut (on the side of the disc) giving only a few laps, enough to
prevent a fall. Leave the quick release open. This has to go on the opposite side of the
brake disc.
Remove the plastic protection from the lower end of the fork and put the wheel so that
the disc fits between the brake calipers.
The disc must be positioned to the left of the bike, in the travel direction.
Ensure that the wheel is locked into the fork by making a small force on the handlebar
from top to bottom. Tighten the axle nut with your hands until it meets resistance, and
then close the quick release system. The quick release system should meet some
resistance as well. If the wheel has not been tightened enough, then release the lock,
tighten the nut and close the system again.

4.1.1.2 CITY BIKES
Release the front V-Brake: press the sides of the horseshoe and release the metal tube.
(See picture).
Loosen the outer nut of the hub of the wheel, one on each side.
IMPORTANT: Loosen only the first outer nut on each side. Do not loosen the other
nuts (showed in the picture), as those are tightening the hub bearings.
Remove the plastic protection from the lower end of the fork and put the wheel so that it
fits. Ensure that the wheel is locked into the fork by making a small force on the
handlebar from top to bottom. Tighten the outer axle nut with a 15 wrench or with an
adjustable wrench while holding the inner nut with a 17 wrench. You should do the
same on both sides.
Put the V-Brake back on its position.
The handlebar has a 90° rotation. Loose the handle stem with a 6 Allen wrench (see
picture). Turn the handlebar and put in its proper position, according to the wheel
position. Finally tighten the handle stem.
IMPORTANT: Loosen this screw only enough to move the piece. Do not totally
unscrew it.

4.1.2 PEDALS
The pedals are not identical. They carry a letter on the axis: R-right L-left.
The right (side dishes) should be screwed clockwise. The left should be screwed in anti-
clockwise.
You can screw them using your hands and then tighten them with a 15 wrench.
IMPORTANT: Tighten the pedals only on the correct side. Otherwise the crank set
and/or pedal itself could be damaged.
4.1.3 SADDLE
In some bikes the saddle is already installed. If it is not, you should open the quick
release system in the bike’s frame located on the seat post. Position the saddle until
cover the minimum insertion mark you see in the tube. Place it to the right height and
close the quick release system.
4.1.4 BASKET
The basket is held by 4 screws: 2 on the lateral side and 2 below.
Before putting the screws, put the basket in its place in order to be sure that the handle
stem won’t interfere with the installation. Otherwise, raise the handle stem up enough
(see Headset/ handlebar).
4.2 FOLDING BIKES
We ship the folding bike completely assembled; you should only adjust the handlebar
and the seat post.

4.2.1 UNFOLDING
Unfold the bike. In order to close the folding bike’s hinge, you should raise the pin and
fit it into the hole once the bike is completely unfold, and then close the quick release. If
it is loose once closed, open it and tighten the nut with a 10 wrench.
To fold the bike, do the same steps in the reverse order.
To adjust the headset, raise the handlebar and align it with the wheel. Fold the handle
down and tighten the screw (see picture).
Raise the handlebars and make sure that it has been perfectly aligned. Otherwise, repeat
the step.
4.2.2 PEDALS
The pedals are not identical. They carry a letter on the axis: R-right L-left.
The right (side dishes) should be screwed clockwise. The left should be screwed in anti-
clockwise.
You can screw them using your hands and then tighten them with a 15 wrench.
IMPORTANT: Tighten the pedals only on the correct side. Otherwise the crank set
and/or pedal itself could be damaged.

4.2.3 SADDLE
Open the quick release system in the bike’s frame located on the seat post. Position the
saddle until cover the minimum insertion mark you see in the tube. Place it to the right
height and close the quick release system.
Between the seat post and the frame there is a cylindrical cap at the top of the tube
which helps you to properly adjust the saddle. Make sure that it is correctly located.
