If this is your first bike then we have one tip for you that's likely more important than any other: keep it clean! A clean bike is a happy bike - it'll save you money, it'll run better, and it'll stop you getting filthy. We've got a guide on how to clean your bike if you've never done it before, as well as a guide to the best bike chain lube to keep your freshly washed chain running smoothly afterwards.
Once you've got it running smoothly you'd do well to make sure you've got the best bike insurance and one of the best bike locks just in case the worst happens and someone tries to steal your pride and joy.
