03 MAINTENANCE
INSPECT THE BICYCLE BEFORE USE
Bicycles are inspected several times throughout the manufacturing process and then at the BH workshop during the
final check. As the bicycle's operation may be affected during transport or third parties may have modified the bicycle
before its sale, the following must be checked before each trip:
• FRAME: no cracks, damage or strange noises.
• CHAIN: it must be lubricated and the transmission system must not make any strange noises.
• BRAKES: the brakes must be working properly. When stopped, press the brake lever with enough strength and
check that it does not touch the handlebars.
• TYRES: the pressure must be correct and there must be no cuts on the tread or on the sides. Also check that
the wear level does not exceed the maximum recommended level.
• WHEELS: the wheels must rotate freely in order to check how they rotate. Also check the space between the
brake lining and the rim, as well as the space between the frame and tyre.
• STEERING: the steering must turn smoothly and with no strange noises.
• SWINGARM ROTATION POINTS: when weight is exerted on the bicycle, the suspension must work as expected
and with no strange noises. If it is not working properly or there is play between the moving parts, this might
mean that the tightening torques are incorrect or that the bearings are worn.
• BEARINGS: the bearings must work properly and with no strange noises. The bearings are subject to wear and
must be replaced to prevent damage to the components on which they are installed.
• ELECTRICAL SYSTEM: if the bicycle features an electrical system, check that it is functioning properly
byensuring that the electrical assistance mode is running and that all parts are functioning properly (motor,
display, change of assistance mode and speed sensor). If there is no electrical assistance, check that all
connections are correct and show no signs of damage.
02 BH WARRANTY
SUBMITTING A WARRANTY CLAIM
All warranty claims must be channelled through an official BH dealer. The dealer will analyse the claim to identify its
scope and perform a preliminary assessment of the incident. The dealer will submit and process the claim directly
with BH. Once BH has defined the corrective measures required, the dealer will send this information to the customer.
All claims must be processed by the official dealer from which you purchased your bicycle. If this is not possible,
please contact us directly. We will help you find an authorised dealer near you:
https://www.bhbikes.com/es_INT/quienes-somos/contacto
WARRANTY OF PARTS OF THE ELECTRICAL ASSISTANCE SYSTEM
As in the case of BH BIKES frames and parts, all electrical components made exclusively for BH will be covered by the
statutory warranty (BH motors feature an extended 5-year warranty after the LIFETIME FRAME warranty is activated).
The warranty period will be established according to the current laws of the country where the bicycle was purchased,
and will start on the date of purchase.
During this period, the holder of the warranty will be entitled to have all manufacturing defects repaired free ofcharge,
including the reimbursement of transport expenses and any losses caused as a result of this. The terms and conditions
are as described in the section "Statutory Warranty" and can be read at:
https://www.bhbikes.com/manuals
Under no circumstances shall the warranty cover the wear and natural ageing of batteries due to use, charging and
storage. Likewise, the buyer must contact the original manufacturer to use the warranty of third-party parts.
CONDITIONS THAT MAY VOID THE WARRANTY OF ELECTRICAL
COMPONENTS
The BH battery and electrical components are covered by the statutory warranty, but the following requirements must
be met:
• No electrical components must be removed or tampered with.
• The service life will vary according to the use, charging and storage conditions.
• Keep the battery charged at all times. Otherwise, the battery may deteriorate faster than normal.

KEEP THE BICYCLE CLEAN
We recommend you follow these basic prevention measures to make sure that the bicycle is in perfect working
order. Failure to observe these recommendations may lead to premature wear or even breakages in specific areas,
suchasgaskets or moving parts.
• Clean the dust and mud with a damp sponge and a gentle and neutral cleaning product.
• Plastic parts must only be washed with soapy water.
• Tyres can be washed with a sponge or brush and soapy water.
• After cleaning the bicycle, dry it by rubbing it firmly with a smooth cloth.
• After each cleaning, lubricate the transmission elements.
Dirt may cause damage that can result in accidents or even death.
Never use pressure washers or steam cleaners.
03 MAINTENANCE
Do not ride your bicycle if it does not meet any of these points! A faulty bicycle may cause serious accidents!
If you are unsure or have any queries, please contact your nearest BH workshop!
Check the tightening torques to make sure that they are as described in the recommendations in the user
manuals. Failure to observe these recommendations may result in accidents and even death.
The effect of the ground and the forces exerted on the wheel subject the bicycle to a lot of stress. Thedifferent
parts will be subject to fatigue and wear because of these dynamic loads. Check the bicycle at regular
intervals to look for signs of wear, scratches, bent parts, wear on the finish or the formation of cracks.
Parts may fail suddenly after their service life has expired. Take your bicycle to an authorised BH workshop
regularly to have these parts replaced if needed.
KEEP THE TRANSMISSION LUBRICATED AT ALL TIMES
After washing the bicycle, the chain transmission's lubrication may have also been washed off. Inspect and lubricate
the chain's links, if needed. Excess lubrication may attract more dirt, causing premature wear and incorrect functioning
of the system.
Never use pressure washers or steam cleaners.
PART MAINTENANCE
The bicycle requires regular maintenance and a minimum number of regular inspections. The frequency of the
maintenance operations depends on the type of vehicle (leisure, road or mountain bike), as well as the frequency and
conditions of use.

03 MAINTENANCE
• CHAIN, COG AND CHAIN RINGS: Follow the instructions supplied by the manufacturer.
• BATTERIES AND ACCUMULATORS: Change for the same type. Check the indication on the outer area.
Remember that the failure to use original parts may cause damage that is not covered by the warranty.
AFTER A FALL, BLOW OR IMPACT
If you suffer a fall, blow or impact, first make sure that you are okay to continue cycling. Do not use the bike if you
are injured and ask for medical assistance if needed.
If you are okay to continue cycling, check the bicycle to make sure that it is in perfect working order:
• Check that the wheels are firmly secured and that the rims are in the centre of the frame and fork. Turn the
wheels. If they cannot be centred in situ because the gap is too small, separate the brakes from the rim so itcan
move freely.
In this case, keep in mind that the braking efficacy will be less.
• Check whether the handlebars or the front of the frame are twisted or broken. Check that the front is firmly
seated on the fork, holding the front wheel firmly between your legs and trying to twist the handlebars with
respect to the front wheel.
• Check that the chain is fitted correctly. If the bicycle fell onto the transmission side, check that it is working
properly. Ask for help to place the bicycle on its saddle and change gears. When the chain fits on the largest
cog, check the distance between the gear and the spokes. If the gear or bracket are bent, the first one may
become stuck on the spokes - Danger of falling! The gear, rear wheel or frame may be damaged. Check the
derailleur. If it has shifted, the chain may come off the gear. The bicycle's transmission will become less
effective (alsorefer to the "Traction" section).
• Check the saddle, upper tube or the bottom bracket box to make sure that there are no defects.
• Lift the bicycle slightly and let it drop onto the ground. If there are any noises, inspect the bicycle for any
loosebolts.
• Inspect the entire bicycle again to check for bent areas, worn finish or cracks.
• Ride again carefully if no problems have been detected during the inspection. Do not brake or accelerate
suddenly or pedal when going uphill. If you are unsure, wait for a car to pick you up instead of risking an
accident. Once home, you should inspect the bicycle carefully again. If you are still unsure or have any queries,
please contact your nearest BH workshop!
Bent aluminium parts must not be straightened, i.e., they must not be repaired. Even afterwards, thereisahigh
risk of breakage, especially in regards to the fork, handlebars, front part, chainsets and pedals. Replace them
for greater safety.
Saddle seat post / Stem Inspection of the fastening screws.

Before each outing Monthly Annually
Action required
Part
You do not need to take the bicycle to an expert if you are skilled, experienced and have the appropriate tools. Immediately
implement the corrective measures if you detect problems. If you are unsure or have queries, please contact BH.
The tasks described above must only be carried out by a trusted bike repair expert.
SPARE PARTS
Original parts must be used to ensure the optimum performance of your bicycle and the utmost safety. Failure to use
original parts may cause damage that is not covered by the warranty.
The most common spare parts are parts prone to wear. The most common ones are tyres, inner tubes, brake pads,
disc brakes and brake pads, as well as rims, when these are part of the brake unit, headlights, position lights,
batteries and accumulators.
• TYRES: Replace them with an equivalent type of tyre. Check the marking on the outside of the tyre
(ETRTOstandard). Keep in mind that using a tyre with a larger outer diameter than the recommended one may
cause the tip of the foot to touch the front wheel or rear wheel guard when the handlebars turn. The cyclist may
lose control of the bicycle and suffer an accident with serious consequences. This can also occur when the
pedal chainset is replaced with a longer one.
• INNER TUBES: Replace them with a suitable type of inner tube, according to the type of tyre. Refer to the
information on the outside of the inner tube (ETRTO standard).
• DISC BRAKES AND BRAKE PADS: Follow the instructions supplied by the manufacturer.
• HEADLIGHTS AND POSITION LIGHTS: Replace the bulb with one of the same type. Check the indication on the
metal area.

04 WARNINGS ON USE
MAXIMUM TYRE SIZE
If you install a tyre of a different size on your bicycle, check and make sure that there are at least 6 mm between the
tyre and other parts of the frame and fork.
MAXIMUM FORK LENGTH (AXLE-TO-CROWN)
Observe the maximum length between the fork axle and the lower part of the steering tube (axle-to-crown). If this
maximum length is not observed, the frame could be damaged due to withstanding a greater load than that for which
it was designed and may cause serious accidents.
POSITION OF THE SPINDLE INSIDE THE FORK TUBE
No steering spacers must be fitted above the stem. Otherwise, the materials could be damaged due to withstanding
a greater load than that for which they were designed and may cause serious accidents.
MINIMUM AND MAXIMUM INSERTION LENGTH OF THE SEAT POST
Failure to observe the maximum and minimum seat post insertion dimensions indicated in this manual may cause
alever effect on the frame. The pressure exerted could damage the frame and cause serious accidents. The warranty
does not cover the damage generated by failing to observe these indications.
MAXIMUM NUMBER OF STEERING SPACERS
This manual specifies the maximum number of steering spacers that can be fitted under the stem. If this maximum
quantity is not observed, the materials could be damaged due to withstanding a greater load than that for which they
were designed and may cause serious accidents.
INTENDED USE
Each bicycle has been designed according to a specific intended use. The models described in this manual meet the
requirements associated with their intended use:
These refer to the conditions that guarantee the proper functioning of the bicycle, such as riding on difficult trails,
unpaved paths and difficult terrain and trails that require technical skills. The maximum jumping and/or drop height
is 61 cm (24").
05 WARNINGS ON USE OF THE ELECTRICAL

• Winter discharging sleep mode or DUT (Discharge Under Temperature): Battery discharging will enter the
deep sleep mode if the temperature is below -20°C, stopping the pedal assistance system from working and
protecting the battery. In such cases, sleep mode will automatically be disabled when the battery exceeds
-20°C.
• Winter charging sleep mode or CUT (Charge Under Temperature): Battery charging will enter sleep mode ifthe
temperature is below 0°C. If charging starts and the temperature falls below this level due to night cooling
orother factors, charging will stop and sleep mode will be activated to protect the battery. In such cases,
sleepmode will automatically be disabled when the battery exceeds 0°C.
• Noise on televisions/radios/computers: Charging near televisions, radios or similar devices may cause static
electricity, flickering images and other interference. If this happens, recharge somewhere that is away from the
television or radio (e.g. in another room).
RECYCLING
Ion-lithium batteries can be recycled but they may harm the environment if they are not managed properly after the
end of their service life. Follow these steps after the end of their service life:
• Classify and recycle each electrical component in a place prepared for the sustainable recycling of such parts.
• Check and make sure that the applicable regulations of your country are observed with regards to batteries.
• Prevent the battery connections from coming into contact with metal objects.
• Do not submerge the battery in water and prevent splashes and dampness.
• Do not hit or drill holes into the battery.
• Make sure that the battery liquid does not touch your hands or eyes in the event of a leak.
• Do not use it if there are external signs of damage.
• Only clean the battery with a dry or damp cloth.
MOTOR
The DC motor is located on the bottom bracket bearing axle. As with any other part of your bicycle, the service life of the
motor depends on how it is used. Under normal conditions, the motor can last for 10 to 20 years, or up to 100,000km.
06 PEDAL ASSISTANCE SYSTEM OPERATION
PEDAL ASSISTANCE SYSTEM
The pedal assistance system is designed to provide the optimal amount of assisted power. It provides assistance
within a standard range, based on factors such as the pedalling force, the speed of the bicycle and the transmission.
The system does not provide assistance in the following situations:
• If the control panel is off.
• When travelling at 25 km/h or faster.
• If you are not pedalling and the throttle function is released at 6 km/h.
• If there is no remaining battery capacity.
• If the assistance mode selected is 0% assistance.
COMPONENTS OF THE PEDAL ASSISTANCE SYSTEM
The BH Bikes pedal assistance system is made up of the following components:
• A. A motor, which drives the bicycle.
• B. A control unit (SW-EN600-L), which, among other things, allows you to select the assistance mode.
• C. A battery, which powers the motor and can be located in different places.
• D. A torque sensor, which reads the force applied to the pedal by the user.
