Eurobike 2015

With the exceptions of wood and bamboo, bicycle frames usually aren't made from sustainable resources. Italian design studio Eurocompositi is setting out to change that, however, with its 3D-printed Bhulk mountain bike frame.

Self-driving technology isn't solely the domain of cars and trucks – bikes are getting in on the act too. We spied the latest example at Eurobike in Germany, where CoModule showed a smartphone-controlled, three-wheeled e-bike prototype.

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.

The Bees Bike has a completely modular design that lets you quickly change over from hardtail to full suspension. You can also adjust sizing and positioning with ease.

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.

The Kick-Varibike, spotted at Erobike 2015 this week, can be propelled by leg or hand power, and the riding experience is likened by the firm to cross-country skiing or stand up paddling.

We’ve seen electric full-suspension mountain bikes before, and we’ve also seen electric trekking bikes. Flyer’s new TX-Series, however, is something you don’t come across too often – an electric full-suspension trekking bike. Gizmag checked it out at Eurobike.

Dropper seat posts are becoming increasingly common on mountain bikes, although they do require yet one more cable to strung along (or inside of) the frame. Magura has presented an alternative – the Vyron eLECT, which is the world’s first commercially-available wireless dropper seat post.

The Fat Bad from Italy's Bad Bike launches with claims of being the world's first folding fat e-bike. Its thick, knobby tires are secured to a folding frame and powered by up to 500 watts of pedal assist.
