SAFETY CHECKLIST
Safety checks are an important part of any ride. In conjunc-
tion with the recommended maintenance in this manual
it is also suggested that a thorough inspection should be
undertaken fortnightly, tightening all nuts and bolts, replac-
ing worn and damaged parts and ensuring all components
are in their correct positions.
WARNING:
Body parts and other objects should be kept
clear from the moving components of the bicycle
when in use, such as the spinning wheels and the
moving chain. When riding always wear appropri-
ate footwear – i.e. shoes that will grip the pedals
and no sandals. Refrain from jumping with your
bike. Jumping puts enormous stress on many
components of your bicycle, especially your front
fork.
Prior to every ride please complete the following safety
checks:
1. Brakes
• Check front and rear brakes are working correctly
• Check brake control cables for wear and ensure they are
oiled and properly adjusted
• Check brake control levers are lubricated and securely
fastened to the handlebar.
• Check brake shoe pads for wear and their positioning in
relation to the rims
