Getting Started / Settings

• Saddle and Handlebar Adjustment: To adjust the saddle height, sit on the bike with stretched legs, ensuring the heel rests on the pedal. The knee should be slightly bent while pedaling. Make sure the saddle does not go beyond the mark on the seat post. If your saddle has damping springs, protect them when installing a baby carrier. The bike is equipped with a quick release for locking the seat post to the frame. Adjust the adjusting nut and activate the lock lever for effective support. To assemble the handlebar on the post, tighten the 4 post screws between 5Nm and 7Nm. Ensure the handlebar is centered on the post using the marking on the handlebar. If you need to disassemble the stem, unscrew the upper screw and loosen the post screws. When reassembling, tighten the upper screw to adjust the slack in the steering and then tighten the post screws, aligning the post and the front wheel.
• Tires: Check the tire pressure regularly. Riding with under-inflated or over-inflated tires can impair performance, cause premature wear, damage the rim, reduce control, or increase the risk of accidents. Check the condition of the rims and replace any tires with heavy wear or notches before using the bike. The recommended tire pressure is 20-40 psi. The air camera dimension is SV19 40/62-584/635 MV 40MM 27.5-29 Valve.
• Brakes: The right handle activates the rear brake, while the left handle activates the front brake. It is recommended to apply an average braking force of 60% to the front brake and 40% to the rear brake. The bike is equipped with 2 hydraulic disc brakes with a 200mm diameter disc at the front and rear wheels.

CAUTION: Like any mechanical component, a bike experiences high stress and wears out. Different materials and components may react differently to wear or fatigue. If the expected lifetime of a component has been exceeded, it may break suddenly, potentially causing injury to the cyclist. Some signs of wear such as cracks, discolorations or staining in areas of high stress indicate that the component has exceeded its lifetime and should be replaced.

GETTING STARTED / SETTINGS

Although your STILUS BIG MOUNTAIN bike has been carefully prepared in our workshops, it is important to ensure the following points before you use your bike for the first time:
Wear a helmet
Wearing a bicycle helmet is highly recommended. It guarantees a reduction of head trauma in the event of a fall. Helmets are mandatory for children under 12 years old.
Bell
The bell will allow you to be heard at 50 m. Check that the mounting position on the handlebars is easy to use.
Assembly Instructions
THIS PRODUCT MUST BE ASSEMBLED BY A TECHNICIAN. THE ASSEMBLY MUST NOT BE TESTED BY AN UNQUALIFIED PERSON.

Saddle and handlebar adjustment

It is important to adapt the settings of your bike to your form. Adjusting the saddle height To check the correct height of the saddle, you must sit with stretched legs, the heel resting on the pedal (fig. A). When pedalling, the knee will be slightly bent (fig. B).

The saddle must not go beyond the mark on the seat post: Minimum insertion. If your saddle has damping springs, these must be protected in case of the installation of a baby carrier to avoid the risk of pinching fingers.
Quick release
Your bike is equipped with a quick release to lock the seat post to the frame. For effective support, adjust the adjusting nut and activate the lock lever by hand.
Handlebar
To assemble the handlebar on the post, tighten the 4 post Screws between 5Nm and 7Nm. Make sure the handlebar is centred on the post using the marking on the handlebar. Stem
To disassemble the stem, completely unscrew the upper screw and loosen the post screws, then remove the post. When reassembling, tighten the upper screw to adjust the slack in the steering and then tighten the post screws, taking care to align the post and the front wheel. We advise you to have these operations carried out by a qualified technician.

Mounting the pedals

Place the right pedal (R) in the crank on the derailleur side (or chain side) and screw in the pivot with the 15 mm wrench provided for this purpose by turning it clockwise. Then place the left pedal (L) in the left crank and screw in the pivot anti-clockwise with the corresponding wrench. Attaching the wrong pedal can cause irreparable damage. Check if the pedal pivot is aligned with the crank thread before tightening. The internal threads of the crank and the pedals will not benefit from the warranty if the pedals were reversed during the assembly phase.

Tyres
Your bike is equipped with a 29inches (29”) wheel. Check tyre pressure. Riding with tyres that are insufficiently inflated or over-inflated can impair performance, cause premature wear, damage to the rim, reduce control or increase the risk of accidents. For safe use, regularly check the condition of the rims. If heavy wear or a notch is visible on one of the tyres, replace it before using the bike.

Maintenance

Check-ups
In order to ensure your safety and the durability of your bike, we strongly advise you to have your VAE periodically checked by an authorized professional:

First check-up: after 1 month or 150 km

• Checking the tightness of the elements: crank, wheel, post, pedals,handlebar and saddle clamp
• Verification of the operation of the drivetrain and assist,
• Checking and adjusting of the brakes
• Tension and/or truing of the wheels.

After the first 1000 km and every 500 km – check the wear of the chain The bike has a very powerful mid-motor so a lot of the power goes through the chain and sprockets, so the chain will wear out faster than on a normal bike. Changing the chain regularly (before 0.07% stretch) will improve the life of the gears. the two smallest sprockets risk wearing before the rest of the cassette and can be replaced separately with the advice of a specialist.

Every year or 2000 km

• Check of wear levels (brake pads, transmission and tyres),
• Check bearings (bottom bracket, wheels, steering and pedals),
• Check cables (brakes and derailleur),
• Check lighting,
• Tension and/or truing of the wheels.
• Changing the break pads

Every 3 years or 6000 km

• Change of the drivetrain (chain, freewheel and chainset),
• Change of tyres,
• Check of wheel wear (spokes and rim)
• Tension and/or truing of the wheels.
• Check of electrical functions.

For a long life of the transmission it is important not to start and not to accelerate on the smallest gears.
General maintenance
Apart from the periodic maintenance described above, we advise you to regularly check the mechanical elements in order to detect if any replacement is necessary on worn parts or if they are showing evidence of premature wear. As a priority, regularly check the condition of the brakes, rims, tyres and lighting.
Cleaning
This should preferably be done with a sponge moistened with warm soapy water; for rinsing, a jet of water (without pressure) will be sufficient. Clean the sides of the rims with alcohol or acetone. With salt water it is imperative to rinse with fresh water after each use to prevent any risk of corrosion.
Lubrication
Lubrication is essential on the various moving components in order to avoid corrosion. This must be carried out regularly on the ball bearings located in the axles of the wheels, chain, derailleur and control cables. It is advisable to use specialised oil for the chain and the derailleur. You should use grease for the other components.
Regular checks
Tightening bolts: lever, crank, pedals and posts.

After-sales service

Wear parts
The different wear parts are standard elements. However, it is always advisable to replace worn parts with the same components as those  originally installed.You will find these parts for sale at your dealership or in specialised cycle shops.
Caution: Like any mechanical component, a bike experiences high stress and wears out. Different materials and components may react differently to wear or fatigue. If the expected lifetime of a component has been exceeded, it may break suddenly risking injury to the cyclist. Cracks, scratches and discolourations in areas of high stress indicate that the component has exceeded its lifetime and needs to be replaced.
