Here's my submission:

Decided to forgo developing the idea further in favour of some work on the presentation.
There needs to be a way to lock the seat into the bike for when the bike is being used in a way that the ride height is the same and does not require adjusting every time.
Storage of the cable locks still needs to be addressed, but this is not a major issue.

In my perception, if we are looking for solution which is flexible
and has versatile usability not dependent on any fixed structure in
the environment, then most simple locks do enough to protect the bike
from just being pushed away by someone.
So for a basic level of protection, a simple lock which can lock the
bike (the wheels with the body or to some fixed structure around) is
good enough.
Now to protect the bike from being picked up n carried away by
someone, a more technology dependent solution maybe better.
Like one of the members suggested that a device with GPS tracking
would be a good solution but the cost is high.
I suggest similar solutions which are more cost effective and easier
to implement.
One solution would be similar to the security system installed in
cars which starts sounding an alarm if someone tries to mess with the
car. The unit suggested by me for bicycles can be made using an
accelerometer or a gyroscope or a combination of both in a small
compact circuit and mounted on a waterproof device securely attached
with the bicycle. This would detect any motion of the bike after it
has been locked. If there is any motion on the bike caused by an
attempt to steal the bike, the device would detect it and transmit a
warning signal to a small key chain receiver kept with the owner.
The owner can check up on the bike if any such warning signal is
received.
Additionally the device can sound an alarm on the bike to startle the
thief and make general people around aware of the theft happening.
Additionally the device on the bike which transmits a warning signal
on being moved can be used to track down the bike in the same way as
wildlife conservationists track animals tagged with wireless
transmitters.
This device can be powered by battery which can be charged by wall
point chargers or by a small dynamo on the bike itself.
Once this device is activated, any attempt to steal or mess with the
bike is almost impossible to be undetected.
The device can be very affordable and compact.

Thought this article would be of interest, though not the type of solution this challenge is looking for.

Integrated Bike Lock (and Pump)

A few months ago the " better bike lock" question got stuck in my head, and I thought about it every time I wandered past the hipster bikes in San Francisco's Mission District. The standard bike lock just seemed like way too cumbersome of a solution. I wondered if you could get rid of all the accessories like the bike lock and pump by "double-purposing" a bike's existing components. Here are some sketches.

Thanks for keeping the ideas flowing - Eric

Bike Lock + Kickstand

The Bike Lock + Kickstand is designed to reduce the ability of a bike to be stolen and act as a theft deterrent. While the lock would not fix the bike to a certain location, it would however lock it in place, as the lock piece would be between the spokes and not allow the back wheel to rotate.

A secondary function of this solution is to act as a kickstand. When the user reaches his or her destination he/she gets of the bike, lowers kickstand, and if locking is desired, lower the piece between the spokes and lock it with a key.

Bike posts with built in locks

My idea came about because I wanted to solve the problem of carrying a big lock. The problem is that bikes are light and one is able to carry it away even if it can't be ridden. So this necessitates heavy duty locking. The workaround or solution I have is to make the locks a communally owned thing which you have access to by key. In other words, my idea is an RFID based locking infrastructure built city wide which you must subscribe to in order to cover the costs of running it (administration, and maintenance for example). You might have these posts throughout the city that have groves/depressions in the pavement beside them. You put your bike under a clamp (that is part of the lock) with its tires in the groves. Then the clamp is lowered onto your bike. (Sort of like those upright bike carriers for hithces) You swipe your card and it locks it in place. The clamp forces your bike down into the groves for your tires. The downforce and the groves/depression make it so thieves can't steal your bike or your wheels even if they're quick release. (They also keep your tires straight.) I've got a rough sketch but I'm too lazy to take a picture.

Cheers

My idea comes from having a locking mechanism within the bike itself. This enables that no moving parts can be stolen. All you have to do is turn a key to activate everything. I didn't have photoshop or AutoCad handy so my diagram is very basic.

When you turn the key,
1. clamps lock on your brake lines
2. As you continue to turn, the turning motion moves them away from their respected wheel, thus applying the 'brakes'
3. The turning motion also moves forth 2 rods, 1 towards the Seat, and the other towards the Handlebars and locks the Seat post to the Seat tube, and Stem to the Head tube respectively.

- Thus locking all movable parts with 1 swift turn of the key.

In addition, inside the cylindrical key lock is a coil that turns the bike into lock mode by default. This makes it easier to lock, but slightly harder to unlock. But releasing tension in the brake lines is a lot easier than trying to create tension in them, so all in all you use less energy.

Quick & easy way to lock up all the parts of your bike. A retractable cable is in the bottom of the seat post, which, when inserted into the locking mechanism (also on the seat post) leaves your bike secure. Thread the cable through your spokes and frame, lock, and leave !

Requirements

1.One key, no messing with unlocking several locks.
2. Locks all wheels and frame to an immovable object.
3. Bike is unridable if locks are bypassed


Three handcuffs joined by an armoured cable, each cuff has its own lock but the cable carries several control lines so that they are all keyed to the master lock.

One key on the master cuff locks/unlocks all three. If the cable is cut, all the locks are locked.
Requires you to break all three locks before you can steal the bike.

Cuff A is permantly fixed to the frame near the rear wheel and locks the wheel to the frame.

Cuff B is permantly fixed to the fame and locks the front wheel to the frame.

Cuff C the master, is on a longer cable and locks to a bike rack etc.

first, the best theft proof bike is no bike! Walk, run, ride your public transit system!

onward!

My design is simple, attach the K10 TD System to your locked bike and would be thieves magically stay away.

This would work best with a real dog, but I suppose a realistic statue with electronics inside and sensors would work sometimes. A bear, lion or skunk may achieve similar effectiveness.

Best of all, it's compatible with all existing bicycles!

1. This device is meant to supplement a rider's existing locking system, not replace it. The bike must still be locked to a stationary object.

2. It prevents theft by intimidation. (Only applicable to thieves who wish to reproduce?)

3. It renders the bicycle useless if the business end is cut off. (Only applicable to those who like to have seats on their bikes.)

Things I did not work out:
Could the locking mechanism be electronic? Should it be mechanical?

Given the locking mechanism, how exactly could it stop thieves from removing the shaft once the spike is cut off.

Hi everyone. I tried to keep this idea simple, since the thing that has most foiled my attempts to prevent thieves from taking my bike has been my own laziness.

in brief, fold the bike around a stationary object, and its stealable pieces interlock with one another to keep the whole thing secure in one step.

By the way, this is my first time posting here, although I've been reading for a while. So give me a cookie, i guess.

I tried a bit of a different approach. Instead of a theft proof bike, I thought it might be interesting to think about a bike no one would steal. The below concept is a simple fixed gear bike. The frame is molded out of ABS plastic. Cities would by the bikes in bulk and distribute them to residents. Residents could customize them if they wanted to with paint, would in general leave them stock and leave them all around the city. Any resident could pick up any bike and ride it to a destination and simply leave it.

This is a bit more socialist than I usually like to be, but I wanted to spend the hour drawing a cool fixed gear bike...
