We've already seen a few bicycles that attempt to provide riders with more exercise by having them pedal with their legs and arms. Ruder-Rad, however, believes that a two-wheeler is too unstable a platform for that kind of locomotion. That's why it's introducing the Ruder Trike.

Wet conditions and bad weather shut down Bonneville Speed Week for the second year in a row this summer, and they didn't much help Venturi and Ohio State, but the team battled through and set a new category electric world record of 240.320 mph (386.757 km/h).

The amount of kit needed to go camping in the great outdoors can soon add up. Which means multi-purpose products can be an absolute godsend. The VSSL Flask is one such item, combining a flashlight, compass and a flask for discreetly storing a beverage of your choice.

In 2013, Estonian designer Indrek Narusk introduced the Viks, a limited-edition stainless steel fixed-gear commuter bike. Now, to celebrate the line's second anniversary, he's rolled out a carbon fiber version.

NASA has previously tested simple 3D-printed rocket components, such as combustion chambers and fuel injectors, but if the technique is to be practical, it has to cope with more complex items ... like a rocket engine turbopump.

The list of materials extruded through a 3D printer seems to grow each week. And while previous glass 3D printing methods have used powdered glass and silica sand, a team of researchers led by Neri Oxman out of MIT’s Mediated Matter Group have developed a 3D printer that extrudes molten glass.

Combine mechanical engineering, experimental theater, and an old dark church, and you’re bound to get some interesting results — a new navigation device, for instance.

Headphones aren't ideal for cyclists needing situational awareness, and most speakers aren't created with bicycle-mounting in mind. Scosche's Bluetooth wireless speaker, the BoomBottle+, is designed to be rugged, loud, and conveniently-shaped to fit in most bicycle bottle cages.

For years, iPhones were the only smartphones that combined premium materials with gorgeous designs. But recently we've seen several Android flagships play that game at least as well. The Samsung Galaxy S6 edge+ is the best example we've seen.

Researchers claim to have hit on the right combination of solar cell type and battery to charge an electric vehicle battery with higher efficiency than ever before. They say the system could make it possible to attach small cells to a car that will charge the vehicle while being driven.

After being unsatisfied with digital banjo simulations, guitarist Jon Langberg came up with the Guitar-Jo, an accessory that gives an electric six-string an identity crisis by making it sound like a banjo.
