2. About Oxygen E-mate and its design
Oxygen E-mate electric bicycle is a two-wheeled bicycle designed for commuting, long distance cycling, or
short trips around the town. It is suitable to use on public roads as well as off road pathways. Oxygen’s unique
frame geometry, called SCT (Sport City Touring), combines three riding positions in one frame, allowing the
cyclist to choose the most optimal and ergonomic one, depending on the cyclist’s power performance as well
as health condition. This makes the Oxygen E-mate very comfortable and efficient on long distances.
Please note that the bike is NOT suitable to be used in extreme conditions such as jumping on extreme
downhill tracks. Also, 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
3. The First Ride
This chapter explains how to set up your bicycle before the first ride, including riding position, safety checks,
and legal requirements.
3.1 Preparing the bicycle before the first ride
It is very important that your bike is set up properly before going on a first ride. At Oxygen, we care about the
comfort of our customers and therefore we see a proper set up of your bicycle as a priority.
Set up of the seat (saddle) height on your bicycle:
It is important that your bike seat (saddle) is at the correct height to ensure that your bike ride is comfortable,
healthy for your knees and you don’t have to put too much energy into pedalling. The points and pictures
below should be helpful to set up the correct position:
A. Please place your bike against the wall.
B. Seating on the bike, hold the brake seat and put your heel on the pedal. Your leg should be almost straight
and your knee should be bent just a little.

While adjusting the seat height, please note that each seat post has a safety marking on the seat pillar – the
seat should never be set up above the safety marks.
3.2 Safety checks before the first ride
3.2.1 Check the tyres pressure
The recommended tyre pressures for Oxygen bicycles should be set between 35-60psi. It is best if the
pressure is set near the higher limit, above 55psi, as this reduces the likelihood of getting the puncture. The
tyres should not be pumped above the maximum recommended pressure – doing otherwise would affect your
comfort of riding and increase a risk of rim damage 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.
3.2.2 Charge the battery for the first time
Before the first use, the battery should be fully charged. The full charging cycle is completed once the green
light on the charger comes on. The red light on the charger means that the charging is in process – please do
not disconnect the battery before the green light is on.
3.2.3 Check the handle bar and stem assembly.
Before your first ride, please make sure that all the stem and handle bar assembly bolts have been securely
tight up. In order to check it, you will need to move the handle bars up and down, and then from the left to
the right. All Oxygen bikes, sold by authorised dealers, are always checked and tested before being sold to an
individual customer. However, the company cannot always guarantee that these procedures have been

7
completed, particularly in the case of online sales. It is therefore crucial to check all those components yourself
before the first ride.
3.2.4 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 fully working condition. 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. When you
cycle in wet conditions, please remember that the braking performance may be poorer than while cycling on
the dry surface. Always include extra braking distance during wet conditions. You should never ride your bike
with none or even only one working brake. Both brakes must be in fully working condition at all times.
3.2.5 Importance of keeping seat posts suspension cover
All Oxygen bikes are equipped with suspension seat post. The moving parts of the post are covered with the
rubber protection. You should always check the condition of the rubber and make sure it is fitted tightly. It is
particularly important when carrying a child on the rear racks saddle to make sure that the child will not put
fingers in the post.
3.3 Legal requirements
It is important that the bicycle is equipped with all necessary safety components such as a bell and a legal
lighting system. Please remember to use the full lighting system when cycling in dark conditions. We do not
recommend using flashing lighting systems – using such systems on public roads is not allowed by the UE law.
In most countries, white colour is used for the front light and red colour for the rear one. Please note that
using green colour for the front light is not allowed by the EU law and should never be installed on a bicycle’s
handlebar in any of the EU countries.
3.4 Your own safety
RULE no.1 We recommend that you
always use a helmet when cycling, regardless of the time or distance of
your ride.
RULE no.2 Please never cycle under the influence of alcohol or drugs, as this significantly increases a risk of an
accident, serious injury or even death.
3.5 Carrying luggage on your bike
3.5.1 Attaching your luggage
It is important to make sure that the luggage is attached securely and doesn’t exceed the maximum
recommended limit. Please make sure you only use appropriate pannier sets for your luggage needs. Each
pannier should be attached securely to the carrier’s railings.
3.5.2 Maximum allowable luggage
Total luggage weight should not exceed 15kgs, including panniers sets. The weight of the luggage should be
placed equally on both sides, with a maximum of 7.5kgs on each side of the carrier.
3.5.3 Warnings regarding carrying luggage
It is important that the luggage weight is placed equally on both sides of the rack without significant
differences in weight on any side.
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 specifically
designed carrier instead
Please do not fix and modify the carrier rack by yourself as this may have an effect on the safety.

8
Fasteners on the rear carrier should be properly fitted and regularly checked. The carrier bolds should be
tightened with 2.5nm torque.
The luggage carrier supplied with the bike is not designed to pull the trailer. Please do not pull the trailer
with this luggage carrier.
Carrying a maximum luggage allowed may have an effect on the bike’s steering and braking
performance.
Please make sure there are no loose straps coming out of the panniers, as they could get caught by
rotating spokes in the wheel.
Please make sure that the luggage fitted on the carrier does not obstruct the visibility of the lights fitted
to the carrier.
4. Battery care and charging process
4.1 Battery charging
It is important to follow these few steps before the first charge. Firstly, the battery must be fully charged before
the first use. In order to charge the battery, you will first need to plug the battery’s round plug into the battery’s
socket. Once it’s done, you can plug the charger’s main plug to the electricity socket. It is important that it is done
in this specific order as connecting the charger’s main plug first may cause a short circuit.
The charging cycle is competed once the green light appears on the charger. The red light on means that the
battery is still in the charging process and it should not be disconnected from the charger until the green light
appears.
4.2 Battery care and maintenance
Once the battery has been fully discharged, it is always best to charge it on the same day, but not earlier than
approx 10-20 minutes after your bike ride as the battery needs some time to cool of.
If you are planning not to use your bike for a longer period of time, it is very important that you charge the battery
before. Batteries stored for longer period of time should be charged for approx 2 hours every 2 months -
neglecting this result in the battery loosing its voltage and gradual damage to the battery.
IMPORTANT: Never open the battery case - the battery case should only be open by an authorised service centre
appointed by Oxygen Bicycles. Unlawful breach of this rule will automatically invalidate the battery warranty.
Opening the battery case by unauthorised individuals may cause a serious injury or even death. Oxygen Bicycles is
not responsible for any accidents and damages caused by unlawful battery maintenance.
4.3 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. Too low pressure will
result in a higher rolling resistance; a higher pressure (within recommended limit), you will feel less rolling
resistance and the bike will be easier to ride.
B. Luggage weight – usually the lighter luggage, the better the range and performance.
C. Pedal assist – the more effort you put into pedalling, the longer distance you can cycle with an electric
assist on
There are also other factors, independent of how the bike is being used. The range quoted in technical
specification is based on the assumption that the cyclist’s weight is no more than 80kg, and he cycles in a relatively
flat area. The range can be lower for cyclists of over 80kgs, as well as for cycling in hilly or mountain areas.
Temperature is another factor that can influence the range, with the best performance achieved in temperatures
between 20 and 25C, and lower range during cold winter days.

6. Regular use and bike maintenance
Any bicycle that is regularly used will require regular routine maintenance. To ensure the maximum safety on your
bike, we strongly recommend carrying a routine maintenance checks described in the paragraph 3.2 before each
ride. Additionally, the following checks should be done approx once a month:
-Spokes – These should be checked after the first 300 miles (approx 500km) from buying your bike, and
then every 500 miles (800km) to make sure spokes are not too loose.
-Brake pads – The condition of brake pads should be checked after every 500 miles. The life time 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. Also, they are more likely to wear out quicker if used in hilly or
mountains areas, compared to flat areas, where less braking is applied.

-Running gears – Running gears should be checked and adjusted if clicking noise can be heard while
changing the gears
-Tyres condition – You should never ride the bike with worn out tyres, as they are more likely to get a
puncture and put you in a risk of an accident
-Chain – Chain should be cleaned and lubricated occasionally as it makes is last longer. Please make sure
that you only use lubricants sold by professional bike shops. Never use motor oil or grease to lubricate
your chain.
-Rims Condition – 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 reducing – a very
worn out rim may explode under a high tyre pressure and cause an accident, serious injury or even death.
It is always best to ask a professional bike shop to check the rims condition for you – usually bike shops
offer such advice for free.

6.3 Fitting the front wheel
The front wheel required occasional checks to make sure it is securely and tightly fitted in the forks and is not too
loose.
What to look at during the front wheel fitment?
The lever should be tight 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. The
pictures below show correct and incorrect way of fitting the front wheel.
