How do whisk pedals work

Remove bike interfaces to reduce the chance of theft?

You can get quick release pedals (some folding bikes use them), with the advantage that the mounting point left behind is too small to pedal effectively. Pedals are also small and relatively clean if you carry them with you, so this works pretty well.

Typically, people with concerns like yours will install a quick release seatpost bolt and take the seat with them instead. But the seats are big and the seat post is often greasy or dirty, so I'm not a fan of this approach. It's also annoying to readjust the seat height every time.

The other terrible thing that people often remove for safety reasons is their front wheel. It's even bigger and dirtier than the seat post.

Some bicycles that are not fully foldable are designed so that they can be easily taken apart. Bike Friday, for example, and everything that S&S clutches use. It is conceivable that you will take one of the smaller pieces with you every time.

A more extreme variant is simply to remove parts and leave them out. Many fixie drivers claim that people will not steal a fixie because they are difficult to drive, for example. Riding a bicycle can be an extension of this idea ... people will not steal a "bicycle" that has a wheel, no gears, and very few valuable components that they cannot ride.

There are a few types of bike thieves and you need to scare them off in different ways. The lazy thief who only wants transport can be deterred by almost anything (bicycle locked with a non-trivial lock); the opportunistic / disorganized thief who steals anything easily and hopes to sell it quickly, for whom all you need is a decent lock and so that your bike can be attached to something solid; and the professional or organized thief for whom nothing less than a security guard will do for as long as your bike is worth stealing. Both of the thieves on sale will also steal components from your bike (as do other cyclists who don't consider themselves criminals). Usually just the easy-to-remove parts like wheels or pumps, but I've had brakes and handlebars stolen from my motorcycles in the past.

A common solution is to take anything valuable off the bike and replace it with cheap crap. This is a Junker bike and they are very popular for this reason.

well, the general consensus seems to be towards a crappy bike. I've been thinking about buying a Norco VFR3 or 4 (hybrid bike) but I think I still need to think about it a bit. Running errands (I think) would be an absolute no no and doing anything that means keeping the bike out with 2 padlocks for more than 5 minutes wouldn't be a good idea, right? (of course without line of sight)

The goal is to have a bike that is not as beautiful as the one around you and is also better secured. IME Most of the time, just locking it in is 99% of the fight. Usually there are motorcycles that are either unlocked, improperly locked, or "locked" with a piece of string. It's only pro-thieves who take the lot that you really need to worry about, and hiring a security officer is the only effective approach here. So use a decent lock, pitlocks if your bikes and saddle are worth it, and move on.
