Oxygen Bicycles allows that certain parts of a bicycle are maintained by the owner. We do, however, recommend that any sorts of maintenance and bike care are made by the qualified cycle mechanic.

1. Lubrication of bike components

Your bike's condition will change after every trip and generally the more you ride the more regular bike maintenance will be required. We recommend that you do carry out regular maintenance checks. Please see a table below for a guide on how often to carry out regular maintenance tasks.

Frequency	Component	Lubricant	How to lubricate
Weekly	Chain Derailleur wheels Derailleur Brake levers	Chain Lube or light oil Chain Lube or light oil Oil Oil	Brush on or o squirt Brush on or o squirt 2 drops from oil can 2 drops from oil can

Annually	Pedals Derailleur cables Wheel bearings Headset	Lithium based grease Lithium based grease Lithium based grease Lithium based grease	Disassemble Disassemble Disassemble Disassemble

NOTES: Please note that the above table is just an example on different kinds of lubricants that can be used and a frequency of using them. Please never use any spray degreasers for lubrication. Always contact your bike dealer for the best advice on what type of lubricant to use. If you feel uncomfortable with doing the routine maintenance by yourself, please use one of the bicycle service centres.

Please note that Oxygen Bicycles do not allow for any sorts of self maintenance of the electrical components. If any problem with the bicycle electrics occurs, never open the battery yourself as this may be dangerous, and inappropariate service to the battery may cause serious injury or even death. Always use a qualified technician when dealing with the batteires.
