MAINTENANCE INSTRUCTIONS
Adjusting Calliper Brakes
Throughout the life of your bike, the front calliper brakes may need adjusting if the brake cable has streched or the brake arms
have been knocked during use.
Adjusting the Caliper Cable Tension
1a
1a. Adjust the Brake Cable
The brake cable must be adjusted to ensure that the
brakes are close as possible to the wheel rim when no
pressure is applied to the brake lever but still allowing
freedom of wheel to rotate.
Using a suitable spanner or socket, loosen the cable
anchor nut until the brake inner wire/or cable is free to
move.
Pull the brake cable until the brake pads are approximately
3 to 4 mm from the wheel rim. Retighten the cable anchor
nut while holding the brake cable position.

Riding In Bad Weather
WARNING! Wet weather impairs traction, braking and visibility, both for the bicyclist and for other vehicles
sharing the road. The risk of an accident is dramatically increased in wet conditions.
When riding in bad weather i.e. wet, foggy, windy or icy, always wear bright, reective clothing which is warm and waterproof.
You should always give other road users clear signals in plenty of time particularly when approaching junctions.
To make sure that you can slow down and stop safely in wet conditions, ride more slowly and apply your brakes earlier and
more gradually than you would under normal, dry conditions.
Be aware that all types of surface become greasy or slippery in bad weather. Do not turn or brake suddenly.
Riding in the Dark
WARNING! When riding in the dark, always make sure that the bike is tted with suitable reectors and a
white front light and a red rear light.
It is essential that other road users can clearly see you when riding in the dark. Always wear bright, reective clothing.
Suitable reectors should be tted to the front and rear of the bike and if possible the wheels. A white light must be tted to
the front of the bike and a red light at the rear.
www.SereneLifeHome.com12
Before starting any journey in the dark or even twilight,
ensure the lights are working correctly and are turned on.
Clean lights and reectors regularly and make sure they
can be seen from distance.
Riding Using Personal Music Players
Listening to music while biking or running roadside
presents danger, as headphones and earbuds impair one
of your most important senses -- hearing.
These devices prevent you from hearing approaching
vehicles and may prove to be a distraction.
They mask trac sounds and emergency vehicle sirens,
distract you from concentrating on what’s going on
around you, and their wires can tangle in the moving
parts of the bicycle, causing you to lose control.
