- Sideways bike
The sideways bike is an invention by Michael Killian, a software engineer from
Dublin . He was inspired by the way thatsnowboard ing is preferred toski ing due to the greater artistic potential, and decided to design a snowboard equivalent for the conventionalbicycle . The result: a bike ridden sideways with the rider operating both wheels. The bike, unlike a conventional bike, uses front-to-back balance like a snowboard. Conventional bikes use left-to-right balance, like skis.Bicycle design
The sideways bike is in many ways different from a conventional diamond-framed bicycle. The rider controls direction by steering with both front and back handlebars. This means that the bicycle can maneuver effectively in congested conditions, weaving in and out of cars and performing tight turns. It also means that the rider can move the bike sideways, as the name suggests, such that the movement is perpendicular to the direction in which the frame points. Although this is possible, it is very difficult as it is necessary for the rider to have extremely good balance.
The position of the pedals and cranks vary from bike to bike. Some sideways bicycles have them positioned in the same way as a normal bike does, however there are some that are placed such that the rider must sit not facing in the direction of movement but perpedicular to it. This means that turning is easier and more elegant, however visibility is impaired as the rider must turn his or her neck all the time.
Sideways bike are single speed, which means that gears have not yet been worked into the complex design of transmission of power from the cranks to the back wheel. Since it pivots, a normal chain system cannot function, but Killian created a part that allows the rear cassette to cause the wheel to rotate even when turning by having an intermediate piece that can transmit the power.
Rather than using a normal saddle for a bike, the sideways bike uses a unicycle saddle for aid balance.
The sizes of the wheels vary considerably between different sideways bikes in order for each bike to be adapted to its purposes correctly.
Advantages and disadvantages over conventional bikes
Advantages
* The sideways bike has a more aerodynamic profile, allowing higher speeds to be reached in comparison hybrid and mountain bikes.Fact|date=October 2007
* Due to the nature of its steering mechanism, the sideways bike has the potential for extremeley small turning radii.
* The rider takes up less room than on a diamond frame bike, leaving more space for luggage.Fact|date=October 2007Disadvantages
* Overlean is a common error that new riders make, caused by leaning too far over when cornering.
* Parts are highly specialist because of such a low volume of riders.
* Neck aches are a common complaint since riders must constantly adjust their positions, depending on which side of the road cars drive.External links
