LIFETIME FRAME WARRANTY

Through its authorised stores, BH Bikes provides the original buyer with a commercial policy to cover any manufacturing defects in frames for a period beyond that specified in the product’s statutory warranty, pursuant to the following clauses:

1. The LIFETIME warranty solely applies to BH frames and bikes that are sold through stores that are authorised by BHBIKES EUROPE S.L.
   • The buyer must register the LIFETIME warranty online, with the information duly completed, within 30 calendar days of the purchase date, as it appears on the invoice issued by the authorised store.
   • This warranty cannot be transferred to subsequent buyers and it is cancelled when the bicycle is sold to a third party. Original buyer means the individual who registers the warranty at the time of the purchase; the commercial warranty cannot be transferred to third parties who are not the original buyer.
   • It shall be compulsory to have the bicycle serviced in an establishment that is authorised by BHBIKES EUROPE and according to the instructions in the user manual.
2. The LIFETIME warranty does not cover:
   • The rear swingarms of the double suspension models, fork, kids’ bikes, defects and/or fading of the original paint, or rust caused by natural deterioration.
   • Defects or breakages resulting from an accident or improper and/or negligent use of the bicycle.

MAINTENANCE

This user manual contains important information for ULTRALIGHT (LR905 / LR805 / LR705 / LR605). Please read the entire manual carefully. The user manuals of all BH models can be consulted on the website at the following address: https://www.bhbikes.com/manuals
This document contains additional information to the general user manual, available at: https://www.bhbikes.com/manuals You can check the characteristics and recommendations of third-party parts on their corresponding official websites.

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.
• 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 obse rve these recommendations may re sult in accidents and e ven 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 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.

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.

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.

PART MAINTENANCE CALENDAR

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 manufacture r.
• HEADLIGHTS AND POSITION LIGHTS: Replace the bulb with one of the same type. Check the indication on the metal area
• CHAIN, COG AND CHAIN RINGS: Follow the instructions supplie d 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” se ction).
• 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.

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.

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 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.

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.

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.

INTENDED USE
Each bicycle has been designed to achieve a specific intended use. The models described in this manual have the following intended use: This is a set of conditions for the operation of the bicycle that provides for its use on asphalt roads. In addition, the wheels must be kept in contact with the running surface at all times.
