Recumbent bicycles may offer a more comfortable riding position, but they typically also have pretty long chains. After all, power has to be transmitted from the pedals at the front to the drive wheel at the back. Norway-based inventor Marc Le Borgne, however, has created an alternative. His KerVelo recumbent has an 18-speed gearhub transmission built into the front wheel.
Aboard an enclosed recumbent bicycle in Nevada today, Canadian Todd Reichart has claimed the world record for human powered speed. The annual World Human Powered Speed Challenge draws cyclists from around the world seeking to push the limits of pedal-powered motion, but it was the 33-year-old who left the competition in his wake to clock a top speed of 85.71 mph (137.9 km/h).
We've already seen a few bicycles – such as the Varibike and Raxibo Hand-Tret-Velo – that are intended to provide riders with more exercise and more power output by having them pedal with their legs and arms. Germany's Ruder-Rad, however, believes that a two-wheeler is too unstable a platform for that kind of four-limbed locomotion. That's why it's introducing the recumbent Ruder Trike.
While they come in various forms, handlebars are a vital component on virtually every type of bike. From the standard 10-speed, to the cargo hauler, to the lean-back recumbent, a bicycle's handlebars provide a simple means of steering and control. As the name suggests, the Joystick Bike replaces the ubiquitous bars with a right-hand joystick, delivering precise control that makes riding a bike a little more like flying an aircraft or playing a video game.
Pain in areas such as the neck, butt and knees cause many cyclists to
switch to recumbents. A lot of other people shy away from the low-slung
bikes and trikes, however, as they have concerns about visibility.
That's why Australian manufacturer Hiele has created the Trivek. It's a
semi-recumbent delta tricycle that lets its rider sit back in a comfy
seat while still sitting tall enough to be seen by motorists.
