<human>:  How do I do basic maintenance on my bike?
<bot>: To do basic maintenance on your bike, you should start by inspecting the chain for any dirt or signs of wear. You should then check the brakes and adjust them if necessary. Next make sure the tires are sufficiently inflated. Check that the bolts and nuts holding the various parts together are properly tightened. Make sure the derailleurs are correctly adjusted and the brakes are working properly. Finally, lubricate the chain when necessary. With these basic steps, you can keep your bike in top condition.
