Frequently Asked Questions - Acqua Scooter NILOX

How to start the electric assistance?

Turn on the battery using the main switch on the side. Then press and hold the display button for 2.5 seconds to turn on the display. Finally, start pedaling: the motor activates after half a crank turn.

What is the battery range and how to optimize it?

The range is approximately 40 to 60 km depending on assistance level, user weight, gradient, tire pressure, and temperature. To optimize, use a moderate assistance level, inflate tires to recommended pressure (2.0-3.5 bar depending on model), and recharge the battery regularly.

How to recharge the battery?

You can recharge the battery directly on the bicycle or after removing it. Plug the provided charger (100-240V) into the battery port, then into a wall outlet. The charger LED is red during charging and turns green when full (approximately 6 hours). Charge in a dry, ventilated area between 0 and 40 °C.

What to do if the display does not show speed?

Check the distance between the magnet on the wheel spoke and the speed sensor. It should not exceed 5 mm. If the problem persists, consult a professional.

How to maintain the chain and transmission?

Clean and dry the chain, then lubricate it with a specific oil. Brush the sprockets and chainrings. Also oil the brake and derailleur cable housings. Perform this operation regularly to prevent corrosion and premature wear.

What tire pressure is recommended?

For the 20" model, pressure is 30 to 50 PSI (2.0 to 3.5 bar). For the 27.5" model, it is 40 to 65 PSI (2.8 to 4.5 bar). Adjust the pressure based on the user's weight.

How to adjust the saddle height?

Open the quick-release system of the seat post clamp. Adjust the height so that when seated, the heel rests on the pedal in the low position with the leg extended. Do not exceed the minimum insertion mark. Close the clamp by hand.

What to do if the motor does not assist pedaling?

First check that the battery is charged. Then inspect the motor cable connections, ensure the brake levers are not stuck in the braked position, and that the battery fuse is not blown. If the problem persists, contact a professional.

How to use the lighting system?

Double-click the display button to turn the lights on or off. The display dims when the lights are on. The system also has a twilight sensor that automatically turns on the lighting if needed.

Can I modify the motor settings or increase the speed?

No. Any modification of electrical parameters, especially the speed limit of 25 km/h, is prohibited and voids the warranty. The bicycle is certified for assistance up to 25 km/h as required by regulations.

Conditions of use of this electrically assisted bicycle

This electrically assisted bicycle is designed for urban and peri-urban use, it allows you to move around town, on the road or on a paved surface where the tires are always in contact with the ground. It is equipped with electric pedaling assistance which will make all your daily trips easier, to go further and for longer. Your electric bike is an adult bike, for people over 14 years old. In the event that the bicycle is used by a child, the responsibility is with the parents and must ensure that the user is able to use the bicycle safely.

Your bike is not intended for use on unpaved or rough terrain. It is not designed for "all-terrain" use, nor for competition. Failure to comply with this practice may result in a fall or accident and may prematurely and potentially irreversibly deteriorate the condition of your electric bike.

Your e-bike is not a moped. The purpose of the assistance is to provide a complement to the pedalling. The moment you start pedaling, the motor kicks in and helps you in the effort. The assistance varies according to the speed of the bike, high at start-up, less sustained when the bike is launched then disappears when the bike reaches 25 km/h. The assistance is cut off as soon as one of the two brake levers is actuated or the speed is greater than 25 km/h. This will resume automatically below 23 km/h with pedalling.

It must be properly maintained according to the instructions in this manual.

WARNING: Like any mechanical component, a bicycle is subject to high stress and wear. Different materials and components may react differently to wear or fatigue. If the expected lifespan of a component has been exceeded, it may break suddenly, risking injury to the cyclist. Cracks, scratches and discoloration in high stress areas indicate that the component has exceeded its life and should be replaced.

Recommendation: Safe and secure use

Before using your e-bike, make sure it is in good working order. Check the following points in particular:

• Position should be comfortable
• Nuts, screws, clamping levers, clamping components
  • The brakes are in working order
• The handlebar travel is good without too much play, the handlebar is correctly fixed to the stem
• Wheels are unobstructed and bearings are properly adjusted
• The wheels are properly tightened and attached to the frame/fork
• The tires are in good condition and their pressure is good.
  • The condition of the rims

• The pedals are firmly attached to the crankset

• The operation of the transmission

• The reflectors are in the correct position.

RECOMMENDATION: Your electrically assisted bicycle must be serviced every 6 months by a professional to ensure that it is in good working order and safe to use. It is the user's responsibility to ensure that all components are in good working order before use.

Pick a safe place away from traffic to familiarize yourself with your new bike. The assistance can be triggered with force, check that your handlebars are straight and that the path is clear.

Make sure you are in good health before getting on your bike.

Handlebar

The bicycle is equipped with a handlebar stem called "Aheadset", you can adjust the height of the stem by increasing or removing the adjustment rings located between the stem and the upper steering bearing.

The inclination of the steering column can be adjusted by acting on the screw indicated in the image to the side.

It is recommended that these operations be carried out by a qualified technician.

Make sure the handlebar is perpendicular to the front wheel axle.

ATTENTION: The handlebar can have a negative influence on the response time of the cyclist during braking and in turns.

Tires

Check tire pressure regularly. Driving with under-inflated or over-inflated tires can affect performance, cause premature wear, reduce range or increase the risk of an accident.

If significant wear or a nick is visible on one of the tires, replace it before riding the bike. A pressure range is indicated on the sidewall of the tire by the manufacturer and in the following table. The pressure must be adapted according to the weight of the user.

				Pressure
Model	Bike size	Air chamber size	Tire size	PSI	Bar
City Cargo	20"	20x2.25	20x2.25	30 – 50	2.0 – 3.5
	27.5"	27.5x2.20	27.5x2.20	40 - 65	2.8 – 4.5

Method for determining correct adjustment of quick-release mechanisms (wheel and seat clamp)

Quick release devices are designed to be operated by hand. Never use tools to block or unblock the mechanism so as not to damage it.

To adjust the clamping force of the wheel axle, you must use the adjusting nut and not the quick release lever. If the lever can be moved with minimal hand pressure, it is not tight enough. It is therefore necessary to tighten the adjusting nut.

The quick-release system must mark the fork dropouts when closed in the locked position.

At each adjustment operation, check that the front wheel is correctly centered in relation to the fork. To adjust, close and open the quick-release mechanisms, apply the following method:

Adjusting the brakes

Before each use, check that the front and rear brakes are in perfect working order.

The right handle activates your rear brake. The left handle activates the front brake.

It is recommended to distribute your braking force on average 60/40 between the front and the rear. The brake lever must not come into contact with the handlebars and the sheaths must not be subject to closed angle trajectories so that the cables slide with the minimum of friction. Damaged, frayed, rusted cables should be changed immediately.

WARNINGS:

• In the event of rain or wet weather, braking distances are extended. It is recommended to anticipate braking in such a situation.
• When cornering and braking, the handlebars can have a negative influence on the cyclist's response time.
• Do not touch the disc brakes after intensive use of the braking system of your electric bike at the risk of being burned.

Adjusting the hydraulic disc brakes

The brake pads exert pressure on a disc fixed in the hub of the wheel. The intensity of the pressure is regulated by a brake lever with a liquid via the pressure exerted via the water hose. Do not apply the brake lever when the wheel is detached from the frame or the fork.

To align the automatic disc brake bracket, unscrew the bracket fixing screw from the brake bracket. Brake with the corresponding brake lever (the brake bracket is correctly positioned) and hold the brake handle in this position by tightening the fixing screws of the bracket bracket.

Check that the inner pad (inside the wheel) is 0.2 - 0.4mm from the disc. If this is not the case and you are not comfortable with this operation, contact a qualified technician. It is recommended that you never pour oil or lubricating material on the disc or pads (when servicing the chain or derailleur, for example). If this happens, the pads or rotor should be degreased or replaced. Check the alignment of the pads by spinning the wheel to use the bike on the road. Discs: the bike is equipped with discs with a diameter of 160 mm.

brake pads are standard, replace them when the pad no longer has any friction elements.

Three electronic components: a rectangular package, a black clip, and a coiled spring (no text or symbols)

Don't forget not only new brake pads must be lapped. Breaking -in is done by using the bike for a few minutes and applying the alternating brakes between stops abrupt and light braking.

Replacement of brake pads

Remove the wheel and remove thr old brake caliper pads. Place the pads new In the stirrup so that that the braking surfaces are touching. Don't touch not the braking surfaces. Insert the pads one by one In the brake caliper.

Wheel wear

As all piece wear, the rim must be controlled regularly. The hoop can weaken and break, you doing lose control or fall.

NB: it is important to check the state of wear of the rims. A rim damaged can be dangerous and must be replaced.

Adjusting the shift system

The bike has several gears interchangeable manually with a derailleur system back.

Be careful, never pedal in back when changing gear and never force the control lever.

Use the right handle to change the rear chainring and the left handle to change the front chainring.

On the slope, the small plateau and the large gable make pedaling easier.

Adjust the transmission ratio (crown/ pinion) according to your needs

Be careful, never pedal in back when changing gear and never force the control lever.

For optimum use of the gear change system, it is advised avoid changing gears except when pedaling intense.

Adjusting the stops

The derailleur travel is adjusted using the H and L screws.

Screw L is used to adjust the upper stop (large gear side).

By loosening screw L, the chain is positioned further outside the large sprocket.

Screw H is used to adjust the lower stop (small pinion side).

By loosening screw H, the chain is positioned further outside the small sprocket.

These manipulations are carried out by quarter turn. With each adjustment, you must obtain perfect alignment between the sprocket, the chain and the pulley of the rear derailleur.

Cable tension adjustment

To set a correct sprocket change, use the knob present on the rear derailleur or the grip. This wheel allows you to adjust the tension of the derailleur cable and allows you to position the derailleur correctly according to the speed chosen.

Chain setting

Your bike is fitted with an external rear derailleur, the chain is automatically tensioned.

New chains are sold with too many links, the first step is to reduce it to the correct length. The safest method is to count the number of links in the old chain in order to adjust the new one. To disassemble the old chain, simply bypass it (remove a rivet).

Once it is removed, the new one must be mounted. To do this, it must be passed around the chainring of the crankset and the rear pinion so that it meshes correctly with the other elements of the transmission. To close the chain we recommend using a quick release. This acts as a female link that fits between two male links. Subsequently, the quick release will also make it easier to remove the chain for cleaning.

In order to check if the length of the chain is correct, it must be put on the small sprocket. In this configuration, the virtual line drawn between the hub of the rear wheel and the axle of the lower pulley of the derailleur must be vertical.

Change of pedals

To change your pedals, identify the pedals by looking at the letter noted on the pedal. The right pedal is marked “R” (Right) and the left pedal “L” (Left). Turn the “R” pedal clockwise to secure it to the crank. Turn the L pedal counterclockwise.

wheel and motor

After the first month of use, it is advisable to tighten your spokes to limit the impact of engine traction on your rear wheel. When starting the engine, a slight noise may occur. This noise is normal because the motor starts and assists pedalling. This noise can become more prominent when fully loaded.

Interview

Your bike requires regular maintenance for your safety but also to increase its lifespan. It is important to check the mechanical elements periodically in order to ensure, if necessary, replacement of worn parts or parts showing signs of wear.

When replacing components, it is important to use original parts in order to maintain the performance and reliability of the bicycle. Be sure to use appropriate spare parts for tyres, tubes, transmission components and the various components of the braking system.

It is the responsibility of the user to use parts different from the original parts.

WARNINGS: Always remove the battery before any maintenance operation.

Cleaning

In order to avoid corrosion of the bike, it is necessary to rinse your bike regularly with fresh water, especially if it has been exposed to sea air.

Cleaning must be done with a sponge, a basin of warm soapy water and a jet of water (no pressure).

RECOMMENDATION : Take special care not to use a high pressure water jet cleaner.

Lubrication

Lubrication is essential on the various components that are in motion in order to avoid corrosion. Oil the chain regularly, brush the sprockets and chainrings, periodically introduce a few drops of oil into the brake and derailleur cable sheaths.

It is advisable to start by cleaning and drying the elements to be lubricated.

It is advisable to use specific oil for the chain and the derailleur. Grease must be used for the other components.

Regular checks

Regarding the tightening of the bolts: lever, crank, pedals, stems.

The tightening torques to be applied are as follows:

COMPONENTS	RECOMMENDED TORQUE (Nm)	SPECIAL INSTRUCTIONS
Pedals on crank arms	10 – 15	Grease the threads
Crank arm on bracket	18 - 20	Grease the threads
Stem/handlebar tightening	9 - 10
Headset tightening	4 – 5
Brake lever	6 – 8	Plunger screw (stem)
Brake callipers	6 – 8
Seat	20 – 22
Seat post clamp	---	Quick release
Wheel	30	Quick release

Other tightening torques depend on the size of the nuts: M4: 2.5 to 4.0 Nm, M5: 4.0 to 6.0 Nm, M6: 6.0 to 7.5 Nm. Tighten the screws evenly to the required torque.

Regularly check the tires and in particular the condition of the rear tire teeth: wear, cuts, cracks, pinching. Replace the tire if necessary. Check the rims and the absence of excessive wear, deformations, blows, cracks...

Revisions

To ensure safety and keep components in good working condition, you should have your e-bike checked periodically by your dealer. In addition, maintenance of your bicycle should be carried out regularly by a qualified technician.
