Maintenance

This user manual contains important information for the proper use and maintenance of your bicycle. Specifically, this document provides information for the BH AEROLIGHT bicycle family (EC196/ EC186 / EC176). It is recommended to read the entire manual carefully. User manuals for all BH models can be found on the BH website at: www.bhbikes.com/manuals. This document provides supplementary information to the general user manual, available at: www.bhbikes.com/manuals. Consult the features and recommendations for third-party components on their respective official websites.

Inspect Bicycle Before Use

Bicycles are inspected multiple times during manufacturing and again in the final quality control by your BH workshop. Since the bicycle's performance can change during transport or if third parties have modified it during storage, you should check the following before each ride:

• FRAME: Ensure there are no cracks, damage, or strange noises.
• CHAIN: Ensure it is lubricated and the transmission system is quiet.
• BRAKES: Ensure the brakes function correctly. While stationary, firmly pull the brake lever and verify it does not touch the handlebar under any circumstances.
• TIRES: Check that the pressure is correct and there are no cuts on the tread or sidewalls. Also, check that the wear level does not exceed the maximum recommended wear.
• WHEELS: Ensure the wheels spin freely. Also, check the clearance between the brake pad and the rim, and the clearance between the frame and the tire.
• STEERING: Ensure the steering turns smoothly and without strange noises.
• SWINGARM PIVOT POINTS: When applying weight to the bicycle, ensure the suspension functions normally and without strange noises. If it does not function correctly or shows play between moving parts, it may indicate incorrect torque settings or worn bearings.
• BEARINGS: Ensure the bearings function correctly and without strange noises. Bearings wear out and must be replaced to prevent damage to the components they are installed on.
• ELECTRICAL SYSTEM: If the bicycle has an electrical system, check that it functions correctly by verifying electrical assistance and that all components are working (motor, display, assist shifter, speed sensor). If there is no electrical assistance, check that all connections are secure and undamaged.

Do not ride if your bicycle does not meet any of these points! A defective bicycle can cause serious accidents! If you are unsure or have any doubts, contact your BH workshop!

Always check torque settings to ensure they match the specifications in the user manuals. Failure to follow these instructions can cause accidents and even death.

Terrain influences and forces exerted on the wheels subject the bicycle to significant stress. Under these dynamic loads, various parts experience wear and fatigue. Regularly inspect your bicycle for signs of wear, scratches, twists, color fading, or early signs of cracks. Parts that have exceeded their service life may fail suddenly. Take your bicycle to a BH workshop regularly to replace questionable parts as needed.

Keep the Bicycle Clean

For proper bicycle maintenance, we recommend following these basic preventive measures. Failure to follow these recommendations may lead to premature wear or even breakage in specific areas like joints and moving parts.

• Clean dust and mud with a damp sponge and a mild, neutral cleaning product.
• Plastic parts should only be washed with soapy water.
• Tires can be cleaned with a sponge or brush and soapy water.
• After cleaning the bicycle, dry it thoroughly with a soft cloth.
• After each cleaning, lubricate the transmission components.

Dirt can hide damage that may lead to accidents or even death. Avoid using pressure washers or steam cleaners at all times.

Lubricate the Transmission

After washing, the chain transmission may become degreased. Check and lubricate the chain links if necessary. Excessive lubrication can attract more dirt, causing premature wear and system malfunction.

Avoid using pressure washers or steam cleaners at all times.

Component Maintenance

The bicycle requires regular maintenance and periodic checks. The frequency of maintenance operations depends on the type of vehicle (city bike, road bike, mountain bike), as well as the frequency and conditions of use.

No specialist is required if you are skilled, experienced, and have the appropriate tools. Take immediate corrective action if deficiencies are detected. If you are unsure or have doubts, contact BH. The indicated tasks should only be performed by a trusted bicycle specialist.

Spare Parts

For optimal bicycle performance and maximum safety, it is crucial to use original parts. Using non-original parts may cause damage not covered by the warranty.

The most common spare parts are wear items. These include tires, inner tubes, brake pads, disc brake pads, brake shoes, rims (as part of the brake unit), lights, position lights, batteries, and accumulators.

• TIRES: Replace with an equivalent tire. Check the E.T.R.T.O. marking on the tire sidewall. Using a tire with a larger outer diameter than recommended may cause your foot to touch the front wheel or the rear wheel guard when turning the handlebars, potentially leading to loss of control and serious accidents. The same can happen if you change the pedal crank for a longer one.
• INNER TUBES: Replace with a suitable inner tube type for the tire. Check the E.T.R.T.O. marking on the inner tube.
• DISC BRAKES AND PADS: Follow the manufacturer's instructions.
• LIGHTS AND POSITION LIGHTS: Replace the bulb with the same type. Check the marking on the metallic area.

Usage Warnings

After a Fall, Blow, or Impact

If you experience a fall, blow, or impact, the most important thing is to check if you are fit to continue riding. Do not use the bike if you are injured and seek medical attention if necessary.

If you are fit to ride, perform a series of checks to ensure the bicycle is fully operational:

• Check that the wheels are still secure and the rims are centered within the frame and fork. Spin the wheels. If the clearance has significantly changed and you cannot center it on the spot, slightly retract the brake pads from the rim so that it spins freely. Note that this will reduce braking effectiveness.
• Check if the handlebars or the front of the frame are twisted or broken. Ensure the front is securely seated in the fork, hold the front wheel between your knees, and try to twist the handlebars relative to the front wheel.
• Check if the chain is correctly seated. If the bicycle fell on the drive side, check its function. Ask someone to help you place the bicycle on its saddle and shift gears. When the chain engages the largest sprocket, observe the distance between the derailleur and the spokes. If the derailleur or its mount is bent, the derailleur may catch the spokes – Risk of falls! The derailleur, rear wheel, or frame may be damaged. Check the derailleur; if it has shifted, the chain may come off. The bicycle will lose its transmission (see also the "Traction" section).
• Check the saddle, top tube, or bottom bracket shell for any damage.
• Lift the bicycle slightly and let it drop to the ground. If you hear noises, inspect the bike for loose bolts.
• Re-examine the entire bicycle for any possible twists, color fading, or cracks.
• Only ride carefully if the inspection results are satisfactory. Do not brake or accelerate abruptly, nor pedal uphill. If you are unsure, wait for a pickup rather than taking risks. Once home, thoroughly re-inspect the bicycle. If you are still unsure or have any doubts, contact your BH workshop!

Bent aluminum parts should not be straightened or repaired. Even after repair, there is a high risk of breakage, especially for the fork, handlebars, front end, cranks, and pedals. For safety, replace them.

Maximum Tire Size

If you install a tire different from the original one, ensure there is at least 6mm clearance between the tire and any part of the frame and fork at all times.

Minimum and Maximum Seatpost Insertion

Failure to respect the minimum and maximum seatpost insertion limits indicated in this manual can create a lever effect on the frame. The applied pressure could damage the frame and cause serious accidents. The warranty does not cover damage caused by non-compliance with these instructions.

Maximum Fork Length (Axle-to-Crown)

Respect the maximum length between the fork's axle and the bottom of the head tube (axle-to-crown). Failure to do so may damage the frame by subjecting it to a load greater than it was designed for, potentially causing serious accidents.

Maximum Number of Headset Spacers

This manual specifies the maximum number of headset spacers that can be placed below the stem. Exceeding this quantity may damage the materials by subjecting them to a load greater than they were designed for, potentially causing serious accidents.

Spider Position in Head Tube

Never install headset spacers above the stem. Failure to comply may damage the materials by subjecting them to a load greater than they were designed for, potentially causing serious accidents.

Intended Use

Each bicycle is designed for a specific intended use. The models described in this manual comply with the following intended use:

This is a component set designed for road use. The wheels must remain in constant contact with the asphalt to ensure the structural longevity of the frame and fork.

• Wash the bicycle with a pressure washer.
• Use the bicycle in adverse weather conditions.
• Transport the bicycle outdoors in the rain.
• Expose the battery to high temperatures. Exceeding 70°C can cause leaks and fire hazards.
• Do not disregard the specified temperature ranges for use, charging, and storage of the bicycle.

Ideal Situations for Maximum Battery Lifespan

We recommend adhering to certain conditions to achieve the maximum battery lifespan:

• Charge on a flat and stable surface.
• Keep out of direct sunlight.
• Keep away from children and pets.
• Ensure no rain or humidity.
• Ensure it is ventilated and dry.
• Maintain a temperature between 15-25°C.
• Do not use the battery below 10% charge. Below this level, the lifespan of the cells may be affected.

Any unauthorized tampering with the electrical system components can result in serious accidents and will void the warranty.

Battery Usage Warnings

Improper use of batteries can cause damage and serious accidents. Comply with the following conditions to avoid them:

• Always use the original charger.
• Do not leave the battery near heat sources.
• Do not heat the battery or throw it into fire.
• Prevent battery terminals from contacting metal objects.
• Do not immerse the battery in water and avoid splashes and humidity.
• Do not hit or puncture the battery.
• Avoid contact with leaked liquid in hands and eyes.
• Do not use if it has external damage.
• Clean the battery only with a dry or damp cloth.

Inappropriate Charging and Discharging Environments and Solutions

The hot and cold environments described below may cause charging to enter standby mode or suspend without fully charging the battery.

• Discharge Standby Mode in Winter or DUT (Discharge Under Temperature): Battery discharge enters standby mode if the temperature is below -20°C, preventing the pedal assist system from functioning and protecting the battery. In such cases, this standby mode will automatically cancel when the battery temperature exceeds -20°C.
• Charge Standby Mode in Winter or CUT (Charge Under Temperature): Battery charging enters standby mode if the temperature is below 0°C. If charging begins and the temperature drops below this level due to nighttime cooling or other factors, charging will stop and enter standby mode to protect the battery. In such cases, this standby mode will automatically cancel when the charging temperature exceeds 0°C.
• Noise on Televisions/Radios/Computers: Charging near televisions, radios, or similar devices can cause static electricity, flickering images, and other interference. If this occurs, recharge in a location away from the television or radio (e.g., in another room).

Recycling

Lithium-ion batteries are recyclable resources but can cause environmental damage if not managed correctly after their useful life. Follow these steps when their lifespan ends:

• Sort and recycle each electrical component in a facility prepared for sustainable management of their recycling.
• Review and comply with your country's battery regulations at all times.

Motor

The DC motor is located in the bottom bracket. Like any other part of your bicycle, the motor's lifespan depends on its use. Under normal conditions, the motor can last from 10 to 20 years, or up to 100,000 km.

Assisted Pedaling System Operation

Components of the Assisted Pedaling System

The BH Bikes assisted pedaling system consists of the following elements:

• A. Motor: Powers the bicycle.
• B. Control Unit: Allows selection of assist modes, among other functions.
• C. Battery: Powers the motor.
• D. Torque Sensor: Reads the force exerted on the pedal by the user.
• E. Display (CORE Display): Shows relevant system information.

Parts of the Control Unit

EC196 / EC186 / EC176

The Core display consists of a ring of 12 LEDs and a button within the ring, which acts as the control unit:

• MULTIFUNCTION BUTTON

Powering the Assisted Pedaling System On and Off

EC196 / EC186 / EC176

The assisted pedaling system is turned on from the Core display, located on the bicycle's stem. Pressing the power button once will start the system. The Core display will turn on, showing a blue animation in a counter-clockwise direction. It will then display the current assist mode.

To turn off the assisted pedaling system, press and hold the multifunction button for 3 seconds. The screen will turn off, and the system will be deactivated.

The Assisted Pedaling System

The assisted pedaling system is designed to provide optimal assisted power. It assists you within a standard range based on factors such as your pedaling force, bicycle speed, and gear selection. The system does not provide assistance in the following situations:

• If the control unit is off.
• If the speed exceeds 25 km/h.
• If you are not pedaling and the accelerator function is engaged at 6 km/h.
• If the battery has no remaining charge.
• If the selected assist mode is 0% assistance.

Selecting the Pedal Assist Mode

EC196 / EC186 / EC176

The system offers the following pedal assist modes:

• Boost: Identified by the Red color. Use when maximum system power is desired.
• Trail: Identified by the Orange color. Use for climbing difficult terrain.
• Eco: Identified by the Green color. Use when you want to travel as far as possible.
• No Assist: Identified by the White color. Use when you want to ride without assisted power. You can still use the other functions of the control unit.

To cycle through assist modes, press the multifunction button once to increase the assist level and twice consecutively to decrease it.

Assistance Levels

To extend battery life and prevent complete discharge that could damage it, assist modes are limited based on battery charge:

• Battery charged above 5%: 100% of maximum assistance level is available.
• Battery charged between 1% and 5%: No assistance. Power is only available to turn on lights and the display.
• Battery below 1%: Off. The battery cannot power the display.
• XPro DD Battery: The XPro battery will provide 100% assistance regardless of its charge level.

Walk Assist Mode

EC196 / EC186 / EC176

The walk assist mode helps the user push the bicycle while walking. To activate it, press and hold the control unit button (regardless of the currently selected assist mode). The CORE DISPLAY LEDs will flash blue, indicating that this mode has been activated. To exit this mode, release the button.

Starting to Pedal

Position yourself on the saddle and firmly grip the handlebars before placing your feet on the pedals. Pay special attention when starting to pedal in a higher assist mode (BOOST or TRAIL mode), as the motor will respond with maximum thrust, posing a risk of losing control. To facilitate acceleration, the motor provides an initial boost immediately after you start pedaling, minimizing the effort required to get the bicycle moving and helping you integrate more quickly and safely into traffic.

• Start pedaling in a low gear (higher sprockets) and with a low assist mode (ECO mode). This provides greater control and safety, requires less energy consumption, and thus offers longer range. Be aware that starting in a higher assist mode (TRAIL and BOOST) can pose a safety risk.
• When pushing the bicycle alongside you, ensure the system is turned off.

Battery Charge Visualization

A 100% charge can provide up to 165km of range. Battery charge level can be visualized in several ways. In all cases, the battery charge indicator provides an estimate of the remaining battery capacity:

• Garmin Device: Garmin devices allow you to view the bicycle's battery level on their own interface.

For models equipped with the CORE display, the battery charge level is indicated by the LED ring. The number of illuminated LEDs indicates the current battery level. Remember that the displayed color only refers to the current assist mode.

Battery and Charger

Your BH battery contains lithium-ion cells, representing the most advanced technology in terms of energy density (energy stored per kilogram of weight and per cubic centimeter of volume).

Lithium-ion batteries have the following characteristics:

• Their performance decreases in extremely hot or cold environments.
• An additional characteristic of BH lithium-ion batteries is that they lack a "memory effect" and are not affected by incomplete discharges.
• They naturally lose charge progressively with use. The battery can be fully discharged (100%) approximately 500 times with a maximum battery degradation of 20%. For partial discharges, only the discharged portion is considered. For example, if we charge the battery every time its charge level drops by 25%, we can charge it to 100% of its initial capacity up to 2,000 times. In conclusion, the guaranteed battery lifespan with a maximum degradation of 20% is at least 20,000 km.

Battery Charging

Due to its advanced Lithium-ion technology, it is not necessary to wait for the battery to fully discharge before connecting it to the charger. Similarly, it is not necessary to perform a 100% charge before reusing it. However, for maximum range, a full charge is recommended.

1. TURN ON THE DISPLAY. IT WILL NOT CHARGE IF IT IS OFF.
2. OPEN THE COVER PROVIDING ACCESS TO THE CHARGING PORT.
3. ALWAYS CONNECT THE CHARGER TO THE BATTERY FIRST, THEN TO THE POWER OUTLET.
4. VIEW CHARGE STATUS AND ERRORS.
5. ALWAYS DISCONNECT THE CHARGER FROM THE BATTERY FIRST, THEN FROM THE POWER OUTLET.
6. CAREFULLY CLOSE THE CHARGING PORT COVER TO PREVENT DIRT AND HUMIDITY FROM ENTERING.
7. THE XPRO BATTERY WILL CHARGE IF IT IS IN THE BOTTLE CAGE AND THE BICYCLE IS CHARGING AND THE DISPLAY IS ON.

Do not charge or use a damaged battery.

Be careful and do not touch the charger during the charging process. It may be very hot, especially in high ambient temperatures.

If a fault occurs during battery charging, remove the charger's power plug from the socket and wait for the battery to cool down.

Never touch the power plug, charging plug, or contacts with wet hands.

Ensure there is no foreign matter in the battery contacts before inserting the battery into the bicycle.

Do not connect the charger's power plug to the battery or bicycle charging port if it is wet or damp. Ensure the power plug is connected only after the battery or bicycle charging port has completely dried.

Do not apply excessive force to the power plug or pull the cable with the power plug connected to the battery.

Turn off the assisted pedaling system before removing the battery from its location on the bicycle.

Use both hands to remove the battery from its location, taking care not to drop it. Dropping the battery on your foot can cause injury and damage the battery.

XPRO Dual Discharge Battery

The XPRO dual discharge battery, or extender, allows for increased bicycle range. It is an external 180Wh battery shaped like a bottle, fitting into a specific bottle cage that must be installed and connected properly to the system by an authorized dealer. Once the bottle cage is installed, the external battery connects to the system simply by inserting it into the cage. It is a Plug&Ride battery that requires no additional connection or labor for operation.

XPRO DD Bottle Cage

The bottle cage features a water-resistant connector, ensuring system protection. Therefore, the user can mount a conventional water bottle in the cage or leave it empty.

Energy Saving Modes

The battery is designed to ensure a long lifespan, thanks to energy-saving modes that prevent inefficient battery consumption:

• Transport Mode: To minimize internal consumption during bicycle transport from the factory to the store, the battery is in Transport mode. The user can definitively exit this mode by charging the battery to 100% before first use. If the battery is not fully charged, it will not deactivate Transport mode and will repeatedly re-enter it quickly for protection. Remember to perform a full battery charge to permanently deactivate this Transport mode.
• Stand By Mode: To minimize internal consumption, the battery automatically enters Stand By mode. This happens automatically when the system detects no charging, discharging, or communication with the battery for 10 minutes. For example, this mode will automatically turn off the control unit after 10 minutes of inactivity, should the user have left it on after parking. The user can exit Stand By mode by simply turning on the bicycle's control unit.
• Letargo or Deep Sleep Mode: To protect the battery during long periods of inactivity or storage (e.g., during winter), the battery automatically enters Letargo or Deep Sleep mode. This occurs automatically when one of the following situations arises:
  • If the battery charge is below 1%, the battery enters Letargo or Deep Sleep mode when it has been in Stand By mode uninterruptedly for 10 minutes.
  • If the battery charge is below 10%, the battery enters Letargo or Deep Sleep mode when it has been in Stand By mode uninterruptedly for 48 hours.
  • If the battery charge is below 40%: Letargo or Deep Sleep mode activates when the battery has been in Stand By mode uninterruptedly for 14 days.
  • If the battery charge is below 80%: Letargo or Deep Sleep mode activates when the battery has been in Stand By mode uninterruptedly for 30 days.
  The user can exit Letargo or Deep Sleep mode by pressing the power or multifunction button. Two flashes with all LEDs in Stand By mode and one flash in Letargo or Deep Sleep mode will be displayed.

Electrical Component System Diagram

Schematic showing the connections between the Battery, XPRO Battery, CORE Display, Bluetooth, Speed Sensor, Motor (BH 2EZMAG), Diagnostic Cable, and Charging Port. It also indicates the optional front and rear lights. Warning: Incorrect handling of electrical components can lead to damage not covered by warranty. Such damage could also cause serious injury or death. BH always recommends consulting an official dealer for diagnosis, repair, or installation of electrical components, as these actions require advanced technical knowledge. If an electrical connection comes into contact with moisture or is dirty due to external contamination, a chemical reaction occurs causing the connections to sulfate. This means the copper in the contacts oxidizes, leading to conductivity failures. The warranty does not cover damage resulting from improper maintenance of connections. To prevent oxidation, periodically clean the connections (male and female) with dielectric degreasers like the one shown in the image above.
