5. Safety and maintenance recommendations
5.1. Safety recommendations
Helmet
For safe riding, use a bicycle helmet.
Tires
Inspect the wear of your tires on a regular basis and verify the tire pressure at
least once a month. Tire pressure: 40-65 PSI depending on the weight of the
user.
Wheel-rims
Take care of any risk of damage in case of defective wheel-rims. Swap them
immediately when the rim is worn out.
Important: braking distance increases on humid or slippery ground
Gears
Like the chain, freewheel must be kept clean and well lubricated. If the chain
has become worn and need to be replaced, then it is likely that freewheel will
also have become worn and should also be replaced. Take the chain off
freewheel and rotate it with your hand. If you hear a grinding noise of
freewheel stops suddenly after spinning it, it may need to be adjusted or to be
replaced. The nexus gear does not require any sort of maintenance.
Signaling device
The bike is silent. In order to alert others as to your presence, you have an
approved signaling device located on the left brake lever: Use it only when
absolutely necessary, don’t abuse it!
WARNING: As with all mechanical components, the bicycle is subjected to wear
high stresses. Different materials and components may react to wear or stress
fatigue in different ways. If the design life of a component exceed, it may
suddenly fail possibly causing injuries to the rider.
