The KEB City has a step-through frame, rear-mounted battery, 28-inch wheels and mud-flaps

South Korean automotive manufacturer Kia looks set to return to its bicycle-manufacturing roots with the showing of two prototype electric bikes at the Geneva Motor Show. Already given a brand name – Kia Electric Bicycle (KEB) – both prototypes are of the "pedelec" variety, meaning they can be pedaled and powered electrically, with one a city and the other a mountain bike.  Read More

Armin Oberhollenzer's Leaos 2.0 Carbon City Design e-bike

Pedal-assist electric bikes come in all shapes and sizes, and are made from a range of materials including aluminum and steel. Armin Oberhollenzer's material of choice is carbon fiber and, though his Leaos 2.0 Carbon City Design e-bike has been making appearances at bike shows throughout Europe since last year, it's now set to land on US soil.  Read More

The Revolights Arc knows how fast you're going, and shines accordingly

Revolights is a bicycle lighting system that first came to our attention three years ago, in which the front of the front wheel lights up to serve as a headlight, while the back of the rear wheel illuminates to act as a tail light. While it's a clever setup, at US$229 for a full kit, it's not cheap. That's why its designers have just announced a more affordable alternative called the Revolights Arc, that combines a tail light and wheel-speed-activated brake light.  Read More

Bike-sharing schemes are commonplace in many urban centers around the globe. Though they offer great convenience for last-mile travel or as an option for inner city commuters, as well as easing the stress on overcrowded roads and public transport systems, to say they involve high performance machines would be a bit of a stretch. ShareRoller is a portable electrical motor designed to build on the practicality of shared bicycle schemes by adding a little power and removing some of the legwork from the mix.  Read More

Flying Machine's F-One 3D-printed titanium bicycle

It’s only ten days since we wrote about the titanium 3D-printed Empire Cycles MX-6 Evo mountain bike, a one-off machine designed to show what can be done with additive manufacturing. This article however is not about a one-off bicycle, but a bespoke, made to measure titanium bicycle manufacturing process that’s getting underway at Flying Machines in Perth, Australia. Each customer is measured, and the dimensions are then used to calculate the exact geometry required and the titanium parts are printed. It is anticipated that the entire process will enable finished bikes to be delivered inside three weeks, at a cost of US$3150.  Read More

Very little beats a sturdy U-lock for securing a bike. For when there's nothing available to which you can secure your bike, however, or if you just want a little extra security against anyone tampering with it, designer Dennis Siegel has devised a solution. The RFID Bikealarm attaches to your saddle and emits a 120dB alarm when it senses movement.  Read More

Industrial Design lecturer Mark Richardson, from Monash University in Melbourne, Australia, has created a velomobile prototype made from salvaged materials, a few off-the-shelf parts and modular 3D printed components. Dubbed FAB Velo, the open source project features a modular design that was developed with the aim of enabling users to build their own velomobile.  Read More

The Fly6 HD camera and tail light

The behavior of drivers at junctions monitored by cameras or on stretches of road under the ever watchful gaze of a radar can be very different to those without. Keen cyclists Andrew Hagen and Kingsley Fiegert from Perth in western Australia are on a mission to give fellow riders the same kind of power. They've designed a rear cycle light named the Fly6 that's capable of recording everything that goes on behind, the theory being that if drivers think there's a camera pointed at them, they'll give cyclists more space and show more courtesy.  Read More

A prototype of the system, with its wacky two valve stems

So, you've upgraded your mountain bike's clincher tires to tubeless, and now you figure you're all up-to-date and on the cutting edge, right? Well, perhaps not for much longer. German tire-maker Schwalbe and bike parts manufacturer Syntace have developed a tubeless dual-chamber tire and wheel system, that they claim should offer better performance than your current old-school single-chamber tires.  Read More

The MX-6 Evo mountain bike, sporting its 3D-printed titanium frame

When it comes to a high strength-to-weight ratio, titanium is just about the best material out there for manufacturing bicycle frames. Unfortunately, those frames are also quite expensive. They could be about to come down in price, however – two British companies recently teamed up to create the world's first 3D-printed titanium bike frame.  Read More
