Well, a hammer and a screwdriver will for now. My main loot from the bike and the fan will be the copper which is usually easy to remove with simple tools.

Later when I start playing with the computer electronics I might use some nitric acid and other stuff to get the gold out. But I need to do some math first to see if its worth the money (those chemicals are expensive!) and the dangers (these chemicals are dangerous!). If not, I will simply sell the electronics directly for scrap, companies pay relatively well for them .
