If you want your bicycle to last as long as possible, it needs to be maintained properly and on time. And it’s not limited to just washing or greasing the chain. It is no less important to periodically check the condition of the brake pads, check the tire pressure and tread, see if the assemblies are not loose and if the gears are shifting properly. For this, you need to have at least a minimal set of bicycle tools, lubricants and other supplies.
