Frequently Asked Questions - NRG Valk

How do I adjust the seat height on my Valk NRG bike?

Loosen the seat post clamp using a hex key (usually 5mm), adjust the seat to your desired height (leg should be slightly bent at the pedal down position), then tighten the clamp securely.

What tools are needed for assembly?

You will need a set of hex keys (4mm, 5mm, 6mm), a tire pump, and possibly a screwdriver. A pedal wrench is also recommended.

How do I maintain the chain on my NRG bike?

Clean the chain with a degreaser and a brush, then lubricate it with bike-specific chain oil. Wipe off excess oil to prevent dirt buildup. Repeat every 200 km or after wet rides.

What is the recommended tire pressure for the Valk NRG?

The recommended pressure is usually 60-80 psi (4-5.5 bar) for standard tires. Check the sidewall of your tire for specific range.

How do I adjust the brakes on my bike?

For V-brakes, use a hex key to adjust the tension of the brake cable via the barrel adjuster, or reposition the brake pads to align with the rim. Ensure both pads contact the rim simultaneously.

What should I do if the gears are skipping?

Check the derailleur alignment and cable tension. Use the barrel adjuster on the shifter to fine-tune. If problem persists, the chain or cassette may be worn and need replacement.

Is the Valk NRG suitable for off-road riding?

Yes, with its front suspension and 28-inch tires, it is suitable for light off-road trails and gravel roads, but not for extreme mountain biking.

How do I install the front wheel?

Insert the wheel into the fork dropouts, ensuring the quick-release skewer or axle nuts are properly seated. Tighten the skewer or nuts firmly, and close the quick-release lever.

What is the weight limit for the NRG bike?

The maximum load is 120 kg (265 lbs), including the rider and any cargo. Exceeding this may compromise safety.

Where can I purchase spare parts for my Valk bike?

Spare parts are available at most bike shops and online retailers. Standard parts like tires, tubes, cables, and brake pads are widely compatible. For specific Valk parts, contact the manufacturer.

Tools Required for Assembly

The bicycle may come supplied with some tools. Tools required for general assembly and maintenance may include, but are not limited to, the following:

• Bicycle torque wrench.
• 8mm / 10mm / 13mm / 15mm / 19mm spanners.
• 2.5mm / 4mm / 5mm / 8mm Allen keys.

• Pliers.
  • Phillips head screwdriver.

Assembly

Before riding, ensure that all required fasteners are tightened to the correct torque. This should be checked after every 3 hours of use for the first 20 hours of ownership. • Ensure that the tyres are inflated to within specification (printed on the tyre sidewall), and that the brakes are operating correctly. • Assembly may require 2 people. • Do NOT allow children to perform the assembly. • Additional tools to those supplied (if any) may be required for assembly, such as a torque wrench, pliers etc.

The bicycle comes with some minor assembly required and may include some necessary tools. There is a protective axle in between the forks to prevent damage. This axle is not to be confused with the actual "through- axle." Please remove and discard this (see image to the right).

Handlebars

1. Carefully place the bicycle assembly on a flat surface so that it rests on the front fork and rear wheel.
2. The handlebar clamp (A) comes pre-assembled and should not require any adjustment, however, may be facing the rear of the bike (for shipping reasons). Loosen (rotate left) the 2 clamp screws (B) using a 5mm Allen key, then rotate the handlebar clamp so it is facing forward. Note that the fork brace (C) faces forward. Firmly tighten (rotate right) the clamp screws.
3. Check for any forward – backward movement in the steering stem by holding the forks firmly and pulling-pushing the handlebar clamp. If any rocking can be seen or felt, remove the rubber cap (D) at the top of the steering stem (E), then using a 5mm Allen key, tighten (rotate right) the top screw (F) sufficiently to remove any movement. Ensure that the top screw is not so tight as to bind the handlebar and make it difficult to rotate.
4. Remove (rotate left) the 4 handlebar yoke screws (G) using a 4mm Allen key, then remove the yoke (H).

1. Place the handlebar assembly (I) centrally into position in the clamp. Rotate it so it is in a comfortable position and the levers / controls are in easy reach of your fingers, then re-install the yoke. Note that the display faces rear and the brake levers face forward. Using a 4mm Allen key and torque wrench, tighten the yoke screws to the specified torque.

1. Loosen (rotate left) the 2 handlebar clamp screws (B) slightly, then rotate the handlebar assembly, as required, so it is aligned "square" to the front fork. That is, the handlebar will be at 90^ to the bicycle frame when the front wheel is straight, then using a 5mm Allen key and torque wrench, tighten the handlebar clamp screws to the specified torque.

The orientation of the front fork is correct when the axle is facing forward. The orientation of the handlebar is correct when the control

cables and brake levers are facing forward. It is ESSENTIAL that the fork and handlebar are assembled correctly. The adjacent image shows correct fork / handlebar assembly.

Seat

When setting seat height, it is important to ensure that the resulting ride position is not only comfortable, but also safe. You should be able to remain

stable and properly handle the bicycle when at a standstill, touch the ground etc. You should also be able to comfortably reach the pedals when riding and

comfortably and safely operate the handlebars and all controls. A good reference height for the seat is at hip height. Do NOT have the seat raised enough so you can see the maximum height marker on the seat post. • Ensure that when the seat is clamped, you cannot rock it back and forth or rotate it.

Side view of a bicycle with blue rim and black handle, showing front wheel assembly and wire mesh detail (no text or symbols)

1. Insert the seat post/seat assembly (J) into the bicycle frame and lower it to a comfortable position – do NOT have the seat raised enough so you can see the maximum height marker (K) on the seat post.

2. Rotate the clamp lever (L) from the unlock position (AA) to the lock position (BB). If the seat post is not clamped firmly, increase pressure by unlocking the clamp, then rotating the adjustment knob (M) right (clockwise) a 14 turn, then re-test and adjust, as necessary.

The seat angle can also be adjusted, again for best comfort. To adjust angle, using a 13mm spanner, loosen (rotate left) the seat clamp nuts (CC) on either side of the seat until the front of the seat can be moved up/down. Set the angle as required, then tighten the nuts securely.

Note that small changes in seat position can have a substantial effect on comfort. It is recommended to make seat adjustments in small increments and test the position, then re-adjust, as necessary.

Front Wheel

It is ESSENTIAL that the wheel quick-release

mechanism is installed and adjusted correctly. Failure to do so will render the bicycle as

dangerous. If you are in any way unsure about installing and adjusting the quick-release, take the bicycle to an authorised service centre or qualified bicycle mechanic. • For bicycles with disc brakes, install the quick-release so the lever is NOT on the brake side.

1. Turn the bicycle over so it is resting on the handlebar and seat – ensure it is not resting on the console.
2. Install the front wheel (N) by lowering it into the fork legs, so that the hollow axle (O) rests in the slots at the bottom of the fork legs. Ensure that the brake disc (P) is on the same side as the brake caliper (Q) and that the disc enters the caliper.

1. Remove the nut (DD) and spring (EE) from the quick-release (R) ("skewer"), then insert the quick-release through the axle from the non-brake side.

2. On the threaded end of the quick-release, re-install the spring, small diameter first, and nut. Screw the nut on, then rotate the quick-release lever (FF) toward the locked position – you should feel resistance in the lever starting at about the halfway point in its rotation. The resistance is the ends of the quick-release pushing the forks against the wheel axle. Continue rotating the lever to the fully closed position – it should

take some force to do this – if you cannot push the lever to the fully closed position, or it is very easy to do so, adjust the quick-release nut (DD) as required until the is (a) wheel is fully secured by the quick-release when the lever is in the closed position, and (b) the quick-release lever requires reasonable force to reach the fully closed position.

To remove the wheel, rotate the quick-release lever to the fully unlocked position, then carefully pull the wheel out from the bicycle forks.

Pedals

It is critical that you follow the pedal to crank arm attachment procedure carefully to ensure correct assembly. During assembly, do NOT use excessive force to screw the pedals into the crank

arms – this may indicate misalignment of the pedals or mis-matched threads. If the pedal does not "feel right" when being screwed in, STOP immediately and check that it is the correct pedal and that it is aligned properly with the crank arm. Failure to follow the instructions here or take due care may damage the equipment and void any product warranty.

1. Starting with the right-hand crank arm (S), identify the right-hand pedal assembly (T), which is identified by having the pedal bolt stamped "R".
2. Very carefully begin screwing the pedal bolt into the crank arm (rotate right / clockwise). If the bolt does not "feel right" when being screwed in, STOP immediately and check that it is the correct bolt and that it is aligned properly with the crank arm. Screw the pedal bolt in fully, then tighten to the specified torque using a 15mm spanner and torque wrench.

1. Repeat the above procedure for the left-hand crank arm, noting that the pedal bolt and crank arm thread is left-hand (rotate left / anti-clockwise to tighten) and that the pedal bolt is stamped "L".

NOTE: If there are no Left and Right markings on the pedals, sit the pedals side by side and inspect the thread on each. As shown in the image below, the thread on the left pedal starts high on the left side, and the thread on the right pedal starts high on the right side.

Ancillary Parts

• Attach the headlight (U) and front mudguard (V) (if applicable) to the fork brace (W) using the 6mm bolt and nut. Firmly tighten the fastener using a 10mm spanner, then rotate the headlight to a suitable angle.
• Attach the rear mudguard bracket (X) to the rear frame brace (Y) using the 6mm bolt and nut. Firmly tighten the fastener using a 10mm spanner. Using a screwdriver, attach the mudguard (Z) to the bracket using the 2 mudguard screws (A1).

Assembly is complete. The bicycle should resemble the following image (mudguards not shown). Please note colours may vary.

Pedal Assistance

Charge the battery prior to use. • Pedal assistance is not mandatory for riding – normal bicycle riding ("pedal power") alone can be used. It is recommended to use pedal assistance when

necessary, and not rely on it solely. When using pedal assistance, also pedal for best efficiency. • The bicycle must be moving, or have sufficient pressure placed on the pedals (in a forward direction) to activate pedal assistance. • If you apply the brakes when pedal assistance is active, the drive provided by the motor reduces in proportion to how much braking pressure you apply. Once the bicycle reaches a sufficiently slow speed or stops completely, pedal assistance automatically deactivates. • Pedal assistance deactivates when a speed of 25km/h or greater is reached. • The way pedal assistance operates may vary depending on how some special functions are set-up.

The bicycle pedal assistance system ("PAS") comprises an electric motor (A) built into the rear wheel hub, a battery pack (B) (internal to the frame) and charging port (C), speed control twist-grip (D), control panel (E), and display (F).

Special Functions

Changing the settings for some functions may cause the bicycle to operate abnormally or in a way that may appear to be a fault. Take extra care when using any special function to avoid making a setting that may adversely affect bicycle operation or how you want it to operate. • Changing settings that may affect electrical components of the bicycle or render it unsafe may void warranty.

The bicycle has a range of special "program" functions that can be accessed by switching the unit ON, then pressing and holding the Increase Pedal Assistance and Decrease Pedal Assistance buttons together until the display changes to "PXx", where "Xx" is a number representing a particular setting. Step between settings by pressing the ON / OFF button. Change values using the Increase Pedal Assistance and Decrease Pedal Assistance buttons. Settings are:

• P0^0 – Factory use do NOT change.
• P0^1 – Sets backlight intensity. 0 = Darkest 2 = brightest.
• P0 ^2 – "Speed units". Sets the speed and distance unit of measure. "0" = kilometres / "1" = miles.
• P0^3 – "System Voltage" Sets the system voltage. This setting is pre-programmed from the factory and should not be changed. (The default value is 36).
• P04 – "Power Off Timer" Allows you to set the amount of time the bicycle will remain ON when not being used.

- 0 = Off permanently (Do not use).

- 1 = 1 min, 2 = 2min etc....

- P0 ^5 – "Pedal Assist Limiter" This increases or decreases the amount of pedal-assist levels you can choose from on your home screen. (PAS)

• 003= This will change the range of PAS levels on your home screen to 3.
• 005= This will change the range of PAS levels on your home screen to 5 (Default Value).

• 009= This will change the range of PAS levels on your home screen to 9.

• P0 ^6 – "Wheel diameter". Sets the wheel diameter (in inches), and is used to calculate speed, distance etc. For example, for 27.5" wheels, ensure setting is "27.5". Incorrect values will cause display errors.

• P0^7 – Factory use only. Do NOT change this value from "1".
• P0 ^8 – "Speed limiter". Sets a speed where pedal assistance is automatically "cut-off". Note that the system does this automatically at approximately 25kmh, therefore values above "25" are inconsequential. "0" = no pedal assistance, "5" = 5km/h etc.

• P0 ^9 – "Pedal Start" This setting dictate whether the user needs to be pedalling for the motor to engage (This affects the speed setting 0 on the Home Screen specifically).

• 0 = Motor will activate when the twist grip is engaged.

• 1 = User will need to pedal before the motor will engage.

- P1 ^0 – "Pedal Assistance Mode" This function controls how the home screen PAS settings work.

• 0 = "Automatic" Twist grip is not required, But the rider must be pedalling for the motor to activate. The higher the value on your home screen, (PAS) the more power will be supplied from the motor, requiring you to pedal less (Cruise control is not engaged in this mode).
• 1 = "Full Pedal Assist" This setting only applies to PAS level 0 on your home screen. In this mode pedalling is not required at all, However P0'9 must also be set to 0 (Cruise control is engaged in this mode).

• 2 = "Semi Pedal Assist" This setting works the same as "Full pedal assist" however in PAS 1-5 you will need to pedal for the motor to engage (Cruise control is engaged in this mode).

• P1 ^1 – Factory use only Do NOT change.

• P1 ^2 – "Pedal Assistance Sensitivity" Determines how quickly pedal assistance ramps up from 0 to 100% The higher the value, the faster the motor will engage when you are pedalling.

- 0 = Slowest, 5 = Fastest

• P1 ^3 – Factory use only Do NOT change. (Default value is 12).
• P1 ^4 – Factory use only Do NOT change. (Default value is 12).
• P1 ^5 – Factory use only Do NOT change.
• P1 ^6 – "Odometer Reset" Press and hold the UP button to reset the odometer.

Guidelines for Using Pedal Assistance

To get the best performance and service life from the pedal assistance system, understand and apply the following techniques:

Note that some characteristics of how pedal assistance functions may differ from that described here as a result of some special function settings.

- When pedal assistance is active, the drive motor engages to provide assistance only while the bicycle is in motion and you are pedalling. The amount of assistance provided depends on your pedalling force and the level of pedal ride assistance currently selected (where applicable) and / or being applied.

• Pedal assistance progressively reduces as bicycle speed increases, and stops completely when the current speed exceeds 25kmh. Pedal assistance re-engages when speed drops below 25kmh (provided you are pedalling).
• Start moving from stationary by pedalling as per a normal bicycle. Using pedal assistance only when "pushing off" places undue loads on the system and uses a lot of energy.
• It is recommended to pedal as per a normal bicycle when riding up inclines. Using pedal assistance only when climbing uses a lot of battery energy.
• Pedal assistance automatically reduces or disengages whenever the brakes are activated (and / or when you stop pedalling).
  • Always switch OFF pedal assistance when you have finished riding, or are stopped for a period.

Using Gears

Some model bicycles are equipped with gears. Gears are used to change the ratio between rotations of the rear wheel and the crank set. This enables you to pedal less and travel faster on flat or downhill sections, or pedal faster and travel slower to climb hills. Gearing is independent to pedal assistance, so pedal assistance operates the same regardless of selected gear. Remember, however, that pedal assistance is "governed" by overall speed.

The selectable gears (A) are located on the rear wheel, known as a "gear cluster" or "cassette". The larger the gear, the less number of rotations per rotation of the crank. The largest gear is the "lowest" and is referred to as "1". As each gear becomes smaller, it is a "higher" gear then the previous and is numbered sequentially. The number of gears may vary between different models. Beneath the gear cluster is the derailleur mechanism (B), which moves the chain so it runs on different gears. The derailleur is operated by the rider using controls mounted on the handlebars. The gear change is "indexed" so each gear selection positively engages – this is factory set and should require no adjustment. There may be slight variations between bicycle models in method to change gear "up" (from a lower gear to a higher gear), or to change gear "down" (from a higher gear to a lower gear). The image shows a "6-speed" type that uses a button (C) for changing up gears (push button to activate derailleur), and a lever (D) for changing down gears (rotate lever forward to activate derailleur).

Guidelines for Using Gears

To get the best performance and service life from the gear change system, understand and apply the following techniques:

• You MUST be pedalling during gear changes.

• Do not attempt to change multiple gears in a single action. Allow each gear change to complete fully before the next change.
  • Always use an appropriate gear for your speed, the terrain and incline. This helps you ride most efficiently.
• Keep the chain and gears properly lubricated and clean.
• If you notice noise after changing gear or an ability to select a gear or the chain not running smoothly, have the gear system inspected and adjusted by a bicycle mechanic or suitably qualified person.

Using Brakes

All bicycle models are equipped with a front and rear wheel braking system. Brakes are used to slow the bicycle down. The braking systems may use different mechanics; however, the functionality is the same, and that is to change the energy of the moving bicycle into heat energy ("friction"):

• For disc brakes, this means pads made from a special friction material pinching against a disc mounted to the centre of the bicycle wheel.
• For rim type "caliper" or "noodle" brakes, this means rubber blocks pinching the outer rim of the bicycle wheel (not the tyre).
• For drum brakes, this means pushing sections (known as "shoes") of special friction material against the inside of cylinder fixed to the centre of the bicycle wheel.

Typical Drum Brake

The brakes are operated by the rider through levers mounted to the handlebars. The left-hand lever operates the rear brake, the right-hand lever operates the front brake. The ability of the rider to adequately slow and/or stop the bicycle depends largely on the skill of the rider, the surface being ridden on and other factors such as rain, tyres, adjustment and condition of the brake parts etc.

Guidelines for Using Brakes

To get the best performance and service life from the brake system, understand and apply the following techniques:

• In wet conditions, which reduces friction, always provide additional distance for braking and adjust how quickly you apply the brakes.
• When applying the brakes, particularly the front brake, use a lower pressure to start with until you feel the brakes starting to "bite", then increase pressure as required. Do NOT over-apply the brakes and cause the wheel to stop rotating – this may result in loss of control.

• Maintain the brake friction components (pads, shoes, rubbers) in good condition and replace when they reach the wear limit.

• Maintain brake adjustment so that the brakes perform effectively, the levers are comfortably positioned, and there is not excessive play in adjustable components.

• If the brakes are not performing effectively, making abnormal noise or any part is not serviceable or cannot be adjusted correctly, have the brakes inspected and adjusted by a bicycle mechanic or suitably qualified person.
• If the brake cables become frayed or otherwise damaged, have them replaced by a bicycle mechanic or suitable qualified person.

Suspension

Some bicycle models are equipped with a front suspension system that may include some adjustment features:

• Suspension "lock-out" (A). When the lever is in the sideways position (as shown), there is no suspension movement – this setting is suitable for riding on smooth surfaces. When the lever is rotated so it faces forward, suspension is active – this setting is suitable for rougher surfaces.
• Suspension "pre-load" (B). Rotate the "nut" anti-clockwise (left), to reduce spring preload and make the suspension action more sensitive. Rotate the "nut" clockwise (right), to increase spring preload and make the suspension action less sensitive.

Batteries and Battery Charging

Never modify the electrical system. Alterations may cause a fire, resulting in serious injury and could also damage the electrical system. • Charge with the supplied charger only. Use of the wrong charger may cause a fire or explosion, resulting in serious injury. • Ensure the voltage and frequency of the charger is compatible with mains electrical supply. • Use the battery charger in dry locations only. • The battery must be charged before first use. • For maximum battery performance and service life, charge the battery after each use, and charge at temperatures between 0 and 40°C (32 and 104°F). • Battery charging generally takes up to 8 hours from discharged to fully charged. Do NOT charge the battery continuously for more than 24 hours. • If the bicycle has not been used for over 4 weeks, charge the battery before use. • Always switch the bicycle OFF after each use.

The battery pack can be recharged repeatedly. However, rechargeable batteries eventually need to be replaced. A significantly reduced operating period after charging indicates that the battery is no longer serviceable and should be replaced. Discard old batteries in an environmentally responsible manner.

The battery charger has a charge status LED indicator:

• Red - Battery charging.
• Green - Battery fully charged.

To charge the battery:

1. Lift the protective cover from the battery charging port (A), located near the crank, then plug the charger connector into the charging port.
2. Connect the charger to a mains electrical supply and switch ON. The indicator LED on the charger illuminates red to show the battery is charging.
3. When the battery is charged (approximately 8 hours), the charger indicator LED illuminates green. Disconnect the charger from the electrical supply, then disconnect it from the bicycle. Be sure to place the protective cover over the bicycle charging port.

Maintenance

Some maintenance activities described may be beyond the scope of some users. Do NOT attempt procedures that you are not comfortable with, or do not have the necessary tools,

experience or knowledge for – take the unit to an authorised service centre or qualified technician for servicing. Items in the maintenance schedule below that are recommended to be performed by a qualified technician are highlighted yellow. • Failure to follow the maintenance recommendations, using incorrect or non-compatible accessories or replacement parts, or general negligence may result in making the product warranty void. Improper adjustment or service may result in damage to the bicycle or make it hazardous. • Maintenance requirements may be affected by any number of factors from your riding style to geographic location. • When new, parts of the bicycle may "break-in" over the course of the first approximate 100km of riding, possibly including the stretching of cables, spoke tension changes etc. It is recommended to have the bicycle inspected and serviced at an authorised service centre or by a qualified technician. • The bicycle components are subject to wear and stress. If a component is weakened through stress, age etc, it may fail without warning. It is important to regularly inspect the bicycle for any signs of component fatigue – look for cracks, fraying, discoloration etc, as this may indicate that a part is near the end of its useful life and should be replaced.

• Clean the bicycle with a soft, damp cloth – do NOT use high-pressure water cleaners or hoses, pressurised air, solvents, abrasives etc. For the console, battery and motor, do NOT use any liquids.
• When transporting in a vehicle, it is recommended to have the battery out of the bicycle during transport.
• Store the bicycle where it will be protected from rain, sun etc. to help prevent corrosion, fading etc.
• For safety, longest possible service life and reliability, maintain the bicycle properly. Use the maintenance schedule below for guidance. It is very important that you check certain systems and components before each and every ride. The proper condition and function of these systems is critical to your safety.

Battery Storage

When storing the batteries for a long period of time:

• Charge the batteries at least every 30 days to avoid capacity loss. Batteries slowly self-discharge when unused over a long period. If the battery cells are left at a critically low charge state, the lifespan and capacity will be permanently reduced.
  • Always disconnect the charger from the mains electrical supply and battery before storing the battery.
• Avoid storing batteries in extreme temperatures, whether hot or cold. The recommended battery storage temperature is between 0 and 25°C (32 to 77°F). Avoid exposing batteries to temperatures at or above 40°C (104°F) for extended periods.
• Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate condensation, as this may cause shorting or corrosion.

Battery Fuse

Use fuses of the same type only – the rating (in Amperes) is printed on the end of the fuse. • If the fuse "blows" regularly, have the bicycle inspected at an authorised service centre.

The bicycle battery / electrical system may feature fuse protection to prevent damage in the event of a short-circuit, overload or over-current situation. For example, if the electrical system is exposed to excessive moisture. On some model bicycles, the fuse is accessible and can be easily replaced. If the fuse is "blown", the bicycle electronics will not be available until the fuse is replaced. To replace the fuse:

1. Using a suitable screwdriver, remove (rotate left) the fuse holder (A) on the battery pack until fully unscrewed, then pull the fuse holder and fuse (B) from the bicycle.
2. Discard the blown fuse. Insert the replacement fuse into the fuse holder.
3. Insert the fuse and fuse holder to the bicycle, and re-install (rotate right) the fuse holder until fully seated.

Brakes

Video Tutorial: Replacing the Brake Caliper

Cable Adjustment

The brake levers are fitted with cable adjusters to compensate for cable stretch and/or adjust how much lever travel is required to activate the brake. A looser cable requires more lever travel to activate the brake, a tighter cable requires less lever travel to activate the brake. Do not over-tighten the brake cable as this may cause the brake to drag when not being pulled, which will affect the performance. Set brake adjustment so there is enough free-play at the lever for a comfortable reach and brake action, however, NOT so much that the lever can be pulled back to the handlebar. The brake can be adjusted at the lever and at the brake caliper:

1. Rotate the lock nut (A) on the brake lever (B) to the left (anti-clockwise) to loosen it, then rotate the cable screw (C) left (anti-clockwise) to tighten the cable, or right (clockwise) to loosen the cable, as required.
2. When adjustment is complete, tighten the lock nut (rotate right). Check that the wheel can spin freely when the brake is not being applied, and that it cannot be rotated when the brake is applied.

If the cable cannot be adequately adjusted at the lever, further adjustment can be made at the brake caliper.

1. Rotate the lock nut (D) on the brake caliper (E) left (anti-clockwise) to tighten the cable, or right (clockwise) to loosen the cable, as required. Check that the wheel can spin freely when the brake is not being applied, and that it cannot be rotated when the brake is applied.

If the cable cannot be adjusted using the lever/brake caliper, re-adjust them so the brake cable is fully slack. Using a 5mm Allen key, loosen the cable bolt (F) sufficiently so that the cable can be pulled through it. Pull the cable through the cable bolt until close to being taught, then tighten the bolt to the specified torque using a torque wrench. Check adjustment, and re-adjust if necessary, as described above.

Pad Adjustment

As brake pads wear, the distance between the friction material of the pad and the disc increases. The calipers feature an adjustment screw (G) that can be used to reduce excessive clearance. Brake pad clearance should minimised, however, not so that the pads touch the disc when the brakes are not being applied. Brake pads should be changed when the brake pad friction material is 0.5mm or less.

1. Using a 4mm Allen key, rotate the adjustment screw right (clockwise) to reduce clearance; rotate left (anti-clockwise) to increase clearance (for example, after replacing the pads).

Video Tutorial:

Replacing The Brake Disks

Pad Replacement

Use manufacturer supplied replacement pads only.

Replace the brake pads when the friction material reaches 0.5mm in thickness. To replace pads:

1. Using a 4mm Allen key, loosen (rotate left / anti-clockwise) the pad adjustment bolt (G). Do not remove the bolt, just loosen it so there is additional pad-to-disc clearance for the new [thicker] pads.
2. Using a 5mm Allen key, loosen (rotate left / anti-clockwise) the caliper mounting bolts (H). Do not remove them, just loosen them to allow easier removal / installation of pads, and caliper alignment.
3. Using a 2.5mm Allen key, unscrew (rotate left) the pad retaining pin (I) then pull it from the caliper.
4. Use a suitable object to "hook" the pads (J) and move them outward of the caliper until you can hold them. Gently pull the pads from the caliper.
5. Slide the new pads into place in the caliper (and on either side of the disc) so the retaining pin holes (K) in the pads and spreader spring (L) align with the retaining pin hole in the caliper. Ensure that the spreader spring is correctly positioned, with the prongs on each side of the pad friction material.
6. Insert the retaining pin and tighten (rotate right / clockwise). Ensure that the pin passes through both pads and the spreader spring.
7. Pull and hold the front brake lever (right-hand handlebar) – this will centre the brake caliper against the disc, then tighten (rotate right) the caliper bolts (H) to the specified torque using a 5mm Allen key and torque wrench.
8. Adjust the pads.
9. Adjust the brake cable.

Tyre Pressures

The tyres must always be inflated to the correct pressure (as specified on the tyre sidewall) before every ride. Riding the bicycle with either too low or too high pressures will affect bicycle performance, may affect effective electrical assistance range, and may render the bicycle as dangerous. Use an accurate pressure gauge when checking pressures.

Chain Care

The chain periodically requires lubrication, depending on frequency of use and conditions etc. If the chain is noisy or running roughly, lubricate it by applying a small amount of bicycle chain lubricant to it. Do not allow the lubricant to get on to the tyres.

For bicycles without derailleur type gears, the chain tension should be set so that there is approximately 15 to 20mm of free-play. If the chain or drive sprockets requires any maintenance further than lubrication and basic chain tensioning, contact an authorised service centre. To adjust chain tension:

1. Using a 19mm spanner, loosen the axle nuts (A) on either side of the bicycle, just enough so they are not clamping up hard against the frame. The axle may have caps on the ends – remove the caps.
2. Using a 10mm spanner, rotate the adjustor nut (B) on the chain side of the bicycle to adjust chain tension. Rotate the nut right (clockwise) to increase chain tension (reduce free-play); rotate left (anti-clockwise) to reduce chain tension (increase free-play).
3. Pull the wheel to the side so it is aligned straight with the frame – check that the wheel is straight by looking down the length of the chain – it should be perfectly straight between front and rear sprockets.
4. Using a torque wrench, tighten the axle nuts to the specified torque. Re-install any axle caps.

Torque Settings

It is important to regularly check all fasteners for adequate tightness. The following are considered highly important, and should be adjusted to the specified torque values using a suitable bicycle torque wrench, sockets and adaptors. Depending on bicycle model and design, some fasteners listed below may not be applicable:

• Front Axle Nut – 35Nm
• Rear Axle Nut – 35Nm
  • Handlebar Clamp Bolt – 10Nm
  • Handlebar Stem Bolt – 24Nm
• Pedal Bolts – 35Nm
• Brake Caliper Mounting Bolt – 7Nm
• Brake Cable Anchor Bolt – 7Nm

Frequently Asked Questions

Is it normal for batteries to get warm when charging?

Yes, it is normal that the batteries will become warm during the charging process.

How long will my batteries last before needing replacement?

Average battery life depends on use and conditions. Even with proper care, rechargeable batteries do not last forever. Generally, lithium-ion batteries will last more than 800 charge-discharge cycles. A partial charge/discharge counts fractionally against those numbers; discharging the battery to 50% then recharging it completely uses up one half of a charge cycle.

"End of useful life" refers to the point at which a battery can no longer supply 60% or more of its original rated ampere-hour (Ah) capacity. At this point, degradation of the battery being able to be fully charged accelerates and the battery will need to be replaced.

What happens if the battery discharges while riding?

Pedal assistance will stop when battery charge reaches a minimum level (check level on the console, if applicable). Lights (if applicable) may still function for a period. Your bike can be ridden without pedal assistance.
