This is “Limousine”, a stretch-bicyle from Wouter Mijland. It is completely impractical, the handlebars put out of the riders reach by the iron-pipe extensions, and even if you were Reed Richards that huge triangle would surely flex and buck like an unmanned fire-hose.

But I love it. Perhaps it is the ridiculous inclusion of the everyday practicalities like lights and a pump on such an outlandish machine, or maybe it is the clean lines and seamless construction. Either way, it actually starts to make tall-bikes look like sensible transport solutions.

You can’t buy it either. The description, “Limousine”, 2008, bycicle [sic], iron pipes”, combined with the Flash site, telegraph that this is art. And who would want it anyway when you could hop onto Mijland’s other cycle project, a bike/shopping cart hybrid (below)?

Play Your Music Everywhere You Go! A great motivator to a great workout!

There’s no question that music can pump us up. And the more pumped up we are while working out, the better results we are going to get from working out. Whether you are inspired by “Eye of the Tiger” or “Chariots of Fire” the Mobile Theme Music Sound System is the perfect accessory for your iPod or any MP3 Player. The durable case houses not only a great sound system but a compartment where you can store your favorite player. You’ll needed it when you start taking on those trails you’ve never imagined possible on your brand new mountain bike. Create a play list of your most inspiring music and elevate your workout to the next level.

The Bike stereo Amplified Speaker is the most portable yet durable sound system you can find. It easily secures around any bicycle handlebar, giving you great and inspiring sound as you power your way up the steepest of hills. Unzip the unit open and you will find a compartment for storing not just your favor media player but also maybe some trail mix or a energy bar. And nothing will beat the portability. Secure it to your handlebars with the strong Velcro straps. Secure it to the volleyball post at the beach. Secure it to the cage of your all-terrain Go Kart. Anywhere you go, the music will follow!

Kevin Cyr’s Camper Bike is “a functioning sculptural piece”, designed to be shown off and to star in Kevin’s own paintings and drawings rather than to actually be slept in, but we love it nonetheless.

The bike, actually modified into a tricycle, carries its home on its back, just like a snail and probably not much faster. But it does solve a problem of bike touring: Where do you sleep? In the old, pre Camper Bike world, you could either carry a tent, sleep under the stars or just bring along a credit card and stay in hotels. Now you can sleep in a real bed, and maybe even use a real toilet.

We say maybe as we’re not sure what’s inside. We suspect that this is, just like the snail’s home, nothing more than a shell. After all, a bed up top in the long section would render the rickety rickshaw dangerously top-heavy, especially on uneven ground. This doesn’t stop us from wanting one, though, if only to freak out other road users. And remember: Always engage the parking brake before sleeping.

Eco Factor: Bike GPS made from recycled computer parts runs on solar energy.

Long and endless bike rides during summer could easily turn into trouble if you don’t have a GPS unit and are not really aware of the roads you’re traversing. Facing similar problems turned an avid DIYer named Brian Nadel into an ingenious inventor who crafted a personal GPS device using nothing more than trashed computer components and some waste software.

The GPS unit is mounted on the handlebar of a bike and uses solar energy for power. The DIYer claims that he didn’t have to pay anything for the device, as all the parts came from his trash bin, but if you’re interested in crafting a device for yourself but don’t have a trash bin the size Brian has, all you will have to pay for the component purchases from eBay and closeout retailers is around $150.

There are some concept gadgets that seem too dreamy to ever be real. This one concept bike, which is an idea for mass transit renovation in central London called London Garden, is probably one of them.

This bike is not like any bike that I have ever seen before, as it also doubles as a generator. See the solar panels on the wheels? Using the sun’s rays and the pedaling of the cyclist, energy is created and stored within the bike itself.

This energy can later be used to turn the bike into an electric scooter or charge another vehicle like a bus. That’s right, part of this design is so cyclists can board specially made buses with their “bike batteries” and plug them into the bus to provide power.

These cyclists will be rewarded by not having to pay a fare, because hey, they’re paying for the fuel, right? Not only that, but there is even plans to store the bikes in the air, so that wind power adds more power.

I don’t know about you, but this concept could not work now. I mean, you would have to completely redo the bus system to get this to work, and major renovations like that take years. However, the designers of London Garden are taking a step in the right direction for greener power as every watt of energy is being harnessed.
