it has been years since i last do a bicycle maintenance. i mean last time i did it i was in primary school. hahaha. so nostalgic. the chain, the wheel, the oil, and the gears. i dont have any motorbike back home which is why i never do this kind of things when i was in secondary school or college years. even in university, i dont care much about my bike and keep on using it without care. I dont have the right tools to do the maintenance though. even for oil i used cooking oil to oil those gears and chain hahaha. well at least i got my bike to run again.
