About Oxygen S-Cross and its design
The Oxygen S-Cross electric bicycle range has been designed for
commuting, long distance cycling, or short trips around the town.
The design ensures the S-Cross is suitable for use on public roads as
well as off road pathways.
Oxygen’s unique frame geometry, SCT (Sport City Touring),
combines three riding positions in one frame, allowing the cyclist to
choose the most optimal and ergonomic position for their needs,
depending on the cyclist’s power, performance, size and health
condition. This makes the Oxygen S-Cross very comfortable and
efficient on long distances.
Please note that the bike is NOT suitable to be used in extreme
conditions such as jumping or extreme downhill tracks. The bicycle
frame is NOT designed for: Extreme Cross Country XC, Dual DS, 4X
Four Cross, Free Ride FR, and Downhill DH.
The maximum allowable payload for the bicycle is:
120kg for the cyclist.
15kg for the luggage located on the rear rack.

Safety checks and preparing the bicycle before
your first ride
Fitting the front wheel
The front wheel requires occasional checks to make sure it is
securely and tightly fitted in the forks and is not too loose.
What to check during the front wheel fitment?
The lever should be tightened up properly to the end of its travel. If
you feel that the lever is too soft during locking, you need to hold
the locking nut on the other end of the axle and turn the lever
around to set up as required.
Setting the correct saddle height on your bicycle
It is important that your bike saddle is at the correct height to
ensure that your bike ride is comfortable and you don’t have to put
too much energy into pedalling.
The below guide should be helpful to set the saddle in the correct
position and ensure your Oxygen bicycle is comfortable:
When sat on the saddle, hold the brake lever and put the heel of
your foot on the pedal when in the bottom position. Your leg
should be almost straight with just a slight bend at the knee, when
the ball of your foot is moved onto the pedal to the position it
would be when pedalling this should increase the bend in your
knee slightly and ensure you are able to ride comfortably and get
optimum power when pedalling.
Please note that each seat post has a safety marking on the seat
pillar – the seat post should never be set above the safety marks on
the seat post when adjusting the height of the seat post.

Check the tyre pressures
The recommended tyre pressure for an Oxygen bicycle is between
40psi and 75psi depending on the type of tyre fitted
(recommended limits are shown on the tyre). It is recommended
the pressure is set near the higher limit as this decreases rolling
resistance and helps to reduce the likelihood of getting a puncture.
Tyres should not be inflated above the maximum recommended
pressure – doing otherwise would affect the comfort of riding and
increase the risk of damage to the wheel rim and tyre explosion.
Please note that keeping the bike in the bright sun may also
increase the pressure in the tyres and therefore it is recommended
to keep a pressure at a slightly lower level during hot summer days.
Charging the battery for the first time
Before using your Oxygen bicycle for the first time you should
ensure that the battery is fully charged.
When the charger is plugged in and showing a red light, this
indicates charging is in progress, when the charge cycle is complete
a green light on the charger comes will show – please do not
disconnect the battery or switch off the power before the charge
cycle is complete.
Check the handle bar and stem assembly.
Before your first ride, please make sure that the stem and handle
bar assembly bolts have been securely tightened and there is no
play in the stem or headset.
Check your brakes
Before your first ride it is crucial to familiarise yourself with the
braking system and make sure that both brakes are in good
working order.
Please remember that the RIGHT HAND LEVER operates the front
brake and the LEFT HAND LEVER operates the rear brake. It is
always best to use both brakes at the same time.
8|P a ge
Oxygen Electric Bicycles Ltd, Unit 9 Stadium Court, Mangham Road,
Rotherham, South Yorkshire S62 6EW
When cycling in wet conditions, please remember that the braking
performance may be affected and brakes may not be as effective as
they are when cycling in dry conditions. Always allow extra distance
for braking when cycling in wet conditions. Both brakes must be in
fully working order at all times, you should never ride your bicycle if
there is a problem with the brakes however small the problem may
be.
For your own safety we recommend that you always wear a helmet
when cycling, regardless of the time or distance of your ride.
Please never cycle under the influence of alcohol or drugs, as this
significantly increases a risk of an accident, serious injury or even
death.
All Oxygen bicycles sold by authorised dealers should be
checked and tested before being delivered to an individual
customer. However, Oxygen Bicycles cannot always
guarantee that these procedures have been completed,
particularly in the case of online sales. It is therefore crucial
to check all the components yourself before the first ride.

Battery care and charging
Battery charging
To ensure optimum performance of the battery fitted to your
Oxygen bicycle it is important to follow these steps.
The battery must be fully charged before the first use. In order to
charge the battery, you will first need to plug the charger into the
socket on the battery then switch on the power to the charger. It is
important that this is done in this specific order as connecting the
charger to the battery when live may cause a short circuit, if this
occurs the battery will not take a charge and the green light will
show on the charger.
When the battery is taking a charge a red light should show on the
charger unit, the charger should not be disconnected while the red
light is showing. When the charging cycle is complete a green light
appears on the charger, this indicates the battery is fully charged
and ready for use, power should be switched off, the charger can
then be removed from the battery.
Battery care and maintenance
If the battery is fully discharged it should be re-charged the same
day, but not earlier than approx 10-20 minutes after your bike ride
as the battery cells needs some time to cool off.
If you are planning not to use your bike for a long period of time, it
is very important that you charge the battery before storage.
Batteries stored for long periods of time should be fully charged
before storage and then charged for approx 2 hours every 2
months failure to do this will result in the battery losing voltage and
irreparable damage to the battery occurring.
Please note, damage to, or failure of batteries caused by neglect
or misuse will not be repaired or replaced under warranty.

How to achieve the maximum battery performance and range
The range and performance of your battery depends on a number
of different factors, such as:
A. Tyres pressure – it is best to keep the tyres pressure in the
region of 55-60 PSI. If the pressure is low this will result in a higher
rolling resistance; a higher pressure (within the recommended
limit) will result in less rolling resistance and the bike will be easier
to ride.
B. Weight of the rider and luggage – the less weight the bicycle is
carrying the better the range and performance will be.
C. Pedal assist – the lower the level of pedal assist more effort you
put into pedalling, the longer distance you can cycle with the
electric assist on.
There are also other factors, independent of how the bike is being
used. The range quoted in the technical specification is based on
the assumption that the cyclist’s weight is no more than 80kg, and
cycles in a relatively flat area. The range may be lower for cyclists of
over 80kgs or when cycling in hilly areas. Temperature is another
factor that can influence the range, with the best performance
achieved in temperatures between 15 and 25C.
IMPORTANT: Never open the battery case - the battery case should
only be open by an authorised engineer at a service centre
appointed by Oxygen Bicycles. Unlawful breach of this rule will
automatically invalidate the battery warranty.
Opening of the battery case or tampering with the batteries by
unauthorised individuals may cause serious injury or even death.
Oxygen Bicycles cannot be held responsible for any accidents or
damages caused by unlawful battery maintenance.

Carrying luggage on your bike
It is important to ensure that any luggage being carried on the rear
carrier is attached securely and doesn’t exceed the maximum
recommended limit. Please make sure you only use appropriate
pannier sets for your luggage needs. Any panniers should be
attached securely to the carrier.
Maximum allowable luggage
Total luggage weight should not exceed 15kgs, including any
pannier sets. The weight of the luggage should be distributed
evenly, with a maximum of 7.5kgs on each side of the carrier.
Warnings regarding carrying luggage
Please do not overload the rear carrier with more than the
maximum allowable weight.
Please do not attach a child seat to the standard rear rack supplied
– you should use a carrier designed specifically for this purpose.
Fasteners on the rear carrier should be properly fitted and regularly
checked. The carrier bolts should be tightened with 2.5nm torque.
Carrying the maximum luggage allowed may have an effect on the
bike’s handling and braking performance.
Please make sure there are no loose items or straps coming from
the panniers or rack, this could damage spokes in the wheel.
Please ensure that luggage fitted on the carrier does not obstruct
the visibility of any lights fitted to the carrier or bicycle.

Regular use and bike maintenance
All bicycles require regular routine maintenance. To ensure the
maximum safety on your bike, we strongly recommend carrying out
checks and routine maintenance before each ride.
Additionally, the following checks should be carried out by a
competent person approximately once per month:
Spokes – Spokes should be checked before the first ride and after
the first 300 miles (approx 500km) of buying your bike, and then at
least every 500 miles (800km) to ensure that the spokes are not
loose and the wheel is still running true. Any damage caused by
spokes working loose or breaking will not be covered under
warranty.
Brake pads – The condition of brake pads should be checked on
regular basis. The position of pads may also need adjusting as wear
occurs.
The life span of brake pads may vary significantly and last as long as
5000 miles or as little as 250 miles depending on the conditions the
bike is being used in. Generally, if used a lot in rain and muddy
conditions, the pads will last less than if used mainly in dry
conditions. Wear will also be much quicker if used in hilly areas,
compared to flat areas, where less braking is applied.
Running gears – Running gears should be checked and adjusted on
a regular basis, if not adjusted this can cause wear to the chain and
gearing.
Tyre condition – You should never ride the bike with worn tyres,
this can affect the handling and safety of the bicycle and increase
the risk of punctures and could put you at much greater risk of
having an accident.
18 | P a g e
Oxygen Electric Bicycles Ltd, Unit 9 Stadium Court, Mangham Road,
Rotherham, South Yorkshire S62 6EW
Chain – The chain should be cleaned and lubricated on a regular
basis to increase performance and lifespan. Please ensure that
only lubricants sold by professional bike shops are used. Never use
motor oil or grease to lubricate your chain.
Condition of rims – If using V-brake type brakes, it is important to
check the condition of the rims occasionally. With regular usage,
rims wear out over time and their wall thickness is reduced – a very
worn or damaged rim may collapse and cause an accident, serious
injury or even death. It is always best to ask a professional bike
shop to check the condition of rims for you – many independent
bike shops offer such advice for free.

Warning: All mechanical components on the bike will wear over
time, depending on the type of the component and the material
used. Any cracks, scratches or colour changes may indicate that the
component has worn and should be replaced.
You should not try and fix any electrical components by yourself;
any electrical problems should be investigated by an Authorised
Oxygen Bicycles Technician.
