What’s better speeding on your bike like a madman? Going faster of course! The Tandem Speed is a race bike for two, designed by Robert Zuchowski.

The Emcycle is an enclosed electric hybrid featuring an aerodynamic body to improve its range and protect from weather, a top speed of 60km/h and a 60km assisted range.

The increase of soft mobility has pushed the car industry to join the bicycle movement: the Lexus Hybrid Bicycle Concept has a very futuristic look and electric shifting gears.

Volkswagen demonstrated their “Bik.e” electric, folding bicycle at the Auto China 2010 in Beijing. Really tiny footprint and they seem to be serious about producing it.

If you’ve always wondered what a bicycle with car wheels would look/handle like, look no further: the Kitten weighs nearly 100kg and features 7 speeds and a foot brake.

From formula 1 engineers Factor 001 is built with no respect for rules or restrictions, featuring carbon-ceramic brakes and an LCD touch-screen that displays biometrics.

Designed to be very narrow for easy docking, this electric bike concept by Yuji Fujimura features an internal charging station for electrical devices like cellphones and laptops.

Featuring a lithium-ion battery, automatic stepless gear transmission, belt drive and integrated lights, the Nishiki is unfortunately only a stylish concept by Fredrik Rudenstam.

There has been virtual concepts, but none built; this is for real, no spokes whatsoever. The hollow space left by the spokes could be used for storage instead of a rack.

If you often cruise in windy areas you might consider wind power to propel yourself. The Whike is a sail mounted on a recumbent tricycle that can get you up to 50km/h.

Unlike most solar panels on bike projects the Sunny Day, by Larry Chen, has a double function for it: power for electrical assist and fairing once on move for added efficiency.

The SolarCab hybrid from SolarLab was developed as a response to the pollution and congestion of London. It gets 80% of its power form the photovoltaics on its roof.

Upright and recumbent in one, the Zweistil, designed by Daniel Knüpfer and Stefan Wallmann for their diploma thesis, has a variable frame which can transform on the go.

Ben Wilson was commissioned by Walk the Plank to create a mobile work of art and he made this four-wheeled recumbent cycle inspired by a child’s wooden toy car.

Using oversized tubing (according to bike standards) Italian designers Fabio Bortolani and Ermanno Righi from Dovetusai studios built this rather square and very glossy fixed gear.

Thomas Neeser redesigned some bicycles for his diploma project, we’re always happy to see unconventional and original concepts that actually work. He even sells them.

Designed by Pablo Lopez the Cheetah uses a stepper system like the Coleoptera in a frog leap motion. The cyclist lays down and uses the body weight to tilt and steer it.

Designed by Olli Erkkilä this offroad fixie is kind of an oxymoron. You might as well take a ride at the south pole (might be too wet in the north) with these fat tires.

Designed by jruiter + studio, the Super-Minimal city bike has an original frame featuring front suspension, disc brake and a read planetary hub directly connected to pedals.

Metal sculptor Josh Hadar makes sculptures that happen to look like narrow, engine-less, wire-frame choppers with dangerously pointy ends that have a lot of spokes.

Students from the New York university made an upside down bicycle. Due to its design you have to pedal backwards to go forward and it looks rather uncomfortable. Watch your head!

Designed by Christophe Sarrazin the Coleoptera uses a stepper system to send power to the wheels. This method allows flatter front end on a recumbent, thus better visibility.
