Oxygen Bicycles allows a certain parts of bicycle to be 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 the bike components

Every time you ride your bicycle its condition changes. The more you ride the more regular maintenance will be required on the bike. We recommend you spend a little time on the regular maintenance checks. Below table is just a guide on how often to carry on the regular maintenance tasks.

NOTES: Please note that the above table is just the example on what kind of lubricants to use and their frequency. Please never use the 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 carrying on the routine maintenance please use one of the bicycle service centres
