About these instructions

Read these operating instructions before commissioning the bicy functions correctly and safely. They are not a substitute for personal training by the BULLS specialist dealer. The operating instructions are a component part of the bicycle. Therefore, if it is resold at a later time, they must be handed over to the subsequent owner.

These operating instructions are mainly directed towards the rider and user of the bicycle. In general,

they are technical laypersons.

Text passages which are directed expressly at specialist staff (e.g. bicycle mechanics), are clearly marked with a blue tool symbol.

Staff at all BULLS specialist dealers have specialist training and qualifications, and are therefore capable of identifying risks arise during maintenance, servicing and repairs on the bicycle. Information for specialist staff does not require technical laypersons to take any action.

Valve

Each wheel has a valve. It is used to fill the tire with air. There is a valve cap on each valve. The on valve cap keeps out dust and dirt.

The bicycle either has a classical Dunlop valve, a Presta valve or a Schrader valve.

4.3.2 Suspension

A suspension fork has two functions which improve the floor contact and the comfort: the suspension and the damping.

Figure 5:

Bicycle without suspension (1) and with suspension (2) when riding over an obstacle

The suspension prevents an impact, e.g. caused by a stone lying

in the way, from being directed directly into the rider's body via a fork. Instead, it is absorbed by the suspension system. This causes the suspension fork to compress. The compression can be disabled so that a suspension fork reacts like a rigid fork.

The compressed suspension fork then returns to its original position. The damper decelerates the movement and thus prevents the suspension system from springing back in an uncontrolled manner, and the fork from oscillating up and down.

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

Page 31

This model series features up to three different

suspension and damping systems:

4.4 Brake system

The bicycle's brake system comprises:

• a rim brake on the front and rear wheels,

• a disc brake on the front and rear wheels or

• a rim brake on the front and rear wheels and an additional coaster brake.

4.4.1 Rim brake (Alternative equipment)

Figure 7: Components of the rim brake with details, example

1 Rear wheel brake 2 Brake pad 3 Brake arm 4 Rim 5 Handlebars with brake levers 6 Front wheel brake

The rim brake stops the movement of the wheel when the rider pulls the brake lever, causing two brake pads, positioned opposite one another, to be pressed onto the rims.

Page 33

There are two alternative versions of the rim brake:

• the hydraulically operated rim brake and

• the cable-operated rim brake.

4.4.1.1 Locking lever (Alternative equipment)

The bicycle with hydraulically operated rim brakes is equipped with a locking lever on both the front wheel brake and the rear wheel brake.

Electric drive system

The bicycle is driven by muscle power via the chain drive. The force which

is applied by pedaling in the direction of travel, drives the front chain ring. The chain transmits the force onto the cassette and then onto the rear wheel.

The bicycle does not have a separate EMERGENCY STOP or EMERGENCY SHUT-OFF button. The drive system with removable display can be stopped in case of emergency by removing the display.

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 limit has been reached.

A pushing aid can be activated. The pushing aid continues to drive the bicycle as long as the rider pushes the plus button on the handlebars. The maximum speed in the process is 3.75 mph. The drive stops when the plus button is released.

4.5.1

Battery

The lithium ion battery has an internal electronic protection circuit. It is matched to the charger and the bicycle. The temperature of the battery is monitored constantly. The battery is safeguarded against deep discharge, overcharging, overheating and short circuit. In case of a risk the battery is switched off automatically by a protective circuit. The battery also switches to sleep mode for self-protection when not used for a longer period.

The service life of the battery can be extended if it is well cared for and, above all, stored at the correct temperatures. Even if the battery is cared for properly, the charge status of the battery reduces as it ages. If the operating time is severely shortened after charging, this is a sign that the battery is spent.

7.9 Suspension and damping

7.9.1 Locking the front wheel suspension (Alternative equipment)

When the fork lock is in the open position, the suspension system has activated suspension and thus

provides the rider and the bicycle with relief. Riding with the fork lock open should therefore be preferred for everyday riding.

When riding downhill or at high speed, for instance, the force which is exerted on the drive is absorbed by the suspension system and reduced by up to 50%. In these cases it is recommendable to close the suspension fork.

The fork lock may be situated directly on the fork or on the handlebars, depending on the version.
