About these instructions

1 About these instructions

Read these operating instructions before commissioning the bicycle to ensure you use all the functions correctly and safely. The operating instructions are not a substitute for personal instruction by the supplying specialist dealer. The operating instructions are a component part of the bicycle. Therefore, if it is re-sold at a later time, they must be handed over to the subsequent owner.

These operating instructions are mainly intended for the rider and operator of the bicycle, who tend to be non-professionals

Text passages which are expressly intended for specialist staff (e.g. bicycle mechanics) are clearly marked with a tool symbol.

Staff at all specialist dealers have specialist training and qualifications, and are therefore capable of identifying risks and preventing hazards which may arise during maintenance, servicing and repairs on the bicycle. Information for specialist staff does not require non-professionals to take any action.

Figure 7: Bicycle brake system with a disc brake, example

1Brake disc 2 Brake calliper with brake linings 3 Handlebars with brake levers 4 Front wheel brake disc 5 Rear wheel brake disc

On a bicycle with a disc brake, the brake disc is screwed permanently to the hub of the wheel.

The brake lever is pulled to increase brake pressure. The brake fluid is used to transfer pressure through the brake lines to the cylinders in the brake calliper. The braking force is boosted by a speed reduction and applied to the brake linings. These apply the brake disc mechanically. If the brake lever is pulled, the brake linings are pressed against the brake disc, and the movement of the wheel is decelerated until it comes to a stop.

Description

3.4.4 Suspension

Both forks and suspension forks are fitted in this model series. A suspension fork is based either on a steel spring or air suspension. Unlike a rigid fork, a suspension fork has two functions which improve floor contact and comfort: suspension and damping.

Figure 9: Bicycle without suspension (1) and with suspension (2) when

riding over an obstacle

The suspension prevents an impact, such as one caused by a stone lying in the bike's path, from being channelled directly into the rider's body via the fork. The impact is absorbed by the suspension system instead. This causes the suspension fork to compress. The compression can be disabled so that a suspension fork reacts like a rigid fork. The switch to disable the fork is called a remote lockout.

After compressing, the suspension fork returns to its original position. If there is a damper, it decelerates movement, preventing the suspension system from springing back in an uncontrolled manner and stopping the fork from vibrating up and down.

034-03212_1.0_03.12.2018

EN_034-03212_1.0_BULLS Brose Center MY19_Inhalt.book Page 33 Monday, December 3, 2018 9:37 AM

Dampers which dampen compressive deflection movements, i.e. a compression load, are called compression dampers or compression dashpots.

Dampers which dampen rebound deflection movements, i.e. a rebound load, are called rebound dampers or dashpots.

3.5 Electric drive system

3.6 Drive system

The bicycle is driven by muscle power via the chain drive. The force which is applied by pedalling in the direction of travel, drives the front chain wheel. The chain transmits the force onto the rear chain wheel and then onto the rear wheel.

You can ride the bicycle like a normal bike at any time, either by switching off the electric drive system or changing the level of assistance to Off. The same applies when the battery is empty.

Description

As well as a drive system operated by muscle power, the bicycle also has an integrated, electric drive system. The electric drive system is made up of 8 components:

Figure 13: Diagram of electric drive system

1 Headlight 2 Display 3 Operating element 4 Rechargeable battery 5 Rear light 6Motor

• A charger which is designed for the battery.

As soon as the required muscle power from the rider pedalling passes a certain level, the motor is activated gently and assists the pedalling motion of the rider. The motor force is determined by the set level of assistance. The assistance depends on the force applied to the pedals by the rider. Drive system assistance is therefore only activated when the rider pedals. This happens regardless of the selected level of assistance. The motor switches off automatically as soon as the rider no longer pedals, the temperature is outside the permitted range, there is an overload or the shut-off speed of 25 km/h has been reached.

034-03212_1.0_03.12.2018

EN_034-03212_1.0_BULLS Brose Center MY19_Inhalt.book Page 37 Monday, December 3, 2018 9:37 AM

If the speed falls below 25 km/h, the assistance is automatically activated again.

A push assist system can be activated. The push assist continues to drive the bicycle as long as the rider pushes the plus button on the handlebars. The speed can be a maximum of 6 km/h in this case.

3.6.1 Rechargeable battery

The lithium ion battery has an internal electronic protection circuit. It is matched to the charger and the bicycle. The battery temperature is monitored at all times. The battery is protected against deep discharge, overcharging, overheating and short circuit. In the event of a hazard, a protective circuit switches the battery off automatically. The battery also switches to sleep mode for self-protection when not used for a longer period. The battery's service life can be extended if it is well maintained and, above all, stored at the correct temperatures. The battery charge status will decrease with age, even if the battery is maintained properly. If the operating time is severely shortened after charging, this is a sign that battery has reached the end of its useful life.

6.1.4 Setting the height-adjustable seat post

 When using your seat post for the first time, you

must give it a firm push downwards to set it in motion. This is due to the natural tendency of the seal to repel oil from the seal surface. You only need to do this before the first use or after a longer period of non-use. Once you have displaced the post through its deflection, the oil spreads on the seal and the post begins to function normally.

The saddle can be shifted on the saddle frame. The right horizontal position ensures an optimal leverage position for legs. This prevents knee pain and painful incorrect pelvis positions. If you have displaced the saddle more than 10 mm, you then need to adjust the saddle height again since both settings affect one another.

 To adjust the seat position safely, either push the

bicycle near to a wall, so that you can lean on the wall to support yourself or ask another person to hold the bicycle for you.

 Climb onto the bicycle.

 Place the pedals into the vertical position (3 o'clock

6.4 Adjusting the suspension

Crash caused by incorrectly set suspension

If the suspension is adjusted incorrectly, the fork may become damaged, so that problems may occur when steering. This will result in a crash and injuries.

 Never ride the bicycle without air in the air

suspension fork.

 Never use the bicycle without adjusting the

suspension fork to the rider's weight.

 Settings on the chassis change riding performance

significantly. You need to get used to the bicycle and break it in to prevent accidents.

The adjustment shown here represents a basic setting. The rider should change the basic setting to suit the surface and his/her preferences.

 It is advisable to make a note of the basic setting.

This way, it can be used as the starting point for subsequent, optimised settings and to safeguard against unintentional changes.

Before the first ride

6.4.1 Adjusting the negative deflection

Negative deflection is compression caused by the rider's weight, including equipment (such as a backpack), sitting position and frame geometry.

Each rider has a different weight and sitting position. Negative deflection depends on the rider's position and weight and should be between 15% and 30% of the maximum fork deflection, depending on the bicycle usage and preferences.

6.4.1.1 Adjusting the steel suspension fork negative

deflection

Alternative

You can adjust the fork by tensioning the spring to the rider's weight and their preferred riding style. It is not the coil spring hardness which is adjusted; it is its pretensioning. This reduces the fork's negative deflection when the rider sits on the bicycle.

 Only adjust the negative deflection when the bicycle is

stationary.

Before the first ride

 The setting wheel may be located under a plastic

cover on the suspension fork crown. Remove the plastic cover by pulling it off upwards.

 Turn the negative deflection setting wheel in a

clockwise direction to increase the spring pretensioning. Turn the negative deflection setting wheel in an anti-clockwise direction to reduce it.

 The ideal setting in relation to the weight of the rider

has been achieved when the shock absorber deflects 3 mm under the stationary load of the rider.

 If applicable, re-attach the plastic cover after

setting the suspension fork.

6.4.1.2 Adjusting the air suspension fork negative deflection

Alternative

Riding without filling pressure will destroy the wheel suspension, the frame and the air suspension elements.

 Never ride without filling pressure in the air

suspension elements.

A normal air pump cannot build up the required pressure with sufficient sensitivity.

 Use a special damper pump to adjust the filling

pressure.

The air chamber valve can be used to adjust the fork suspension to the rider's weight and driving style.

Adjusting the tyre pressure

 The tyre pressure determines the force required to

press the fork together. If the tyre pressure is reduced, the fork slackens more and rebounds less.

Figure 48: Screw caps in different designs

 Only adjust the tyre pressure when the bicycle is

stationary.

 The air valve is located under a screw cap on the

head of the left shock absorber. Unscrew and remove the screw cap.

 Adjust the air pressure as an initial value using a

high-pressure damper pump and based on the tyre pressure table on the fork and the rider's weight.

6.5 Retracting brake linings

New brake linings take time to break in and adjust to their final braking force.

 Accelerate bicycle to about 25 km/h.

 Brake bicycle until it comes to a halt.

 Repeat process 30–50 times.

 The brake linings and brake discs are now retracted

and provide optimal braking power.
