A US designer has introduced the concept of "double unicycles", which will allow commuters to ride sideways to beat congestion.
Those who have craved to ride a unicycle about town but decided it was slightly impractical will finally be able to fulfill their wish. The Bicymple resembles a unicycle, but with the addition of a front wheel, a frame, and handlebars.
Its maker, Josh Bechtel of Scalyfish Designs, based in Washington, said that it will change the way people cycle.
The bicymple is an attempt to make the bike more straighforward, using pedals attached to the rear wheel rather than a chain.
The bicymble can be ridden in two modes - with the rear steering locked, making it feel like a "normal" bicycle, or unlocked so it can be ridden in "crab mode" allowing tighter turns and even sideways riding.
Bechtel said that he wanted the design to make a bicycle simpler than current designs.
"Is it possible to evolve from the established bicycle design while adhering to the basic principles of simplicity, functionality, style, and excitement?" the Daily Mail quoted him as saying on the project's website.
"By removing the chain, the number of moving parts and overall complexity is significantly reduced. A direct-drive, freewheeling hub joins the crank arm axis with the rear-wheel axis, shortening the wheelbase and minimizing the design.
"More than just a stylish concept bike, the bicymple is comfortable, easy to ride, and brilliantly simple to maintain," he said.
The lightweight design and short wheelbase make for a nimble ride.
"The optional rear-steer mode is remniscent of custom 'swing bikes' and allows tighter turns and 'crab-riding'," he said.
The bizarre bicycle is supposedly easier to store in small spaces.
Bechtel also says the bike is far better suited than current designs to city riding and storing in apartments.
"The ultra-compact design makes it effortless to get in and out of tight spaces and easily squeezes into stairwells, hallways, fire escapes, nooks, and crannies," he added.
The steel frame is just two bars running above and between the two wheels, with the forks sitting diagonally so there is just a small gap between the 29-inch front and rear wheels.
The project is currently a concept, but Bechtel hopes it make be mass produced, and is "currently exploring options for larger scale production and distribution."
