Maybe it has been the influence of the current scene: the hype(大肆宣传) among urban biking. Apparently, urban biking requires entirely different bikes than suburban biking does and therefore a Bike Design Project started where five design studio across five cities had to come up with a perfect urban bike. The winning bike will be manufactured (制造) for a limited run of 100 bikes and will be in stores next year. Industry, a Portland-based studio, came up with a very interesting bike: one that uses Bluetooth and handlebars that tell you when to stop or turn.

Industry worked together with Ti Cycles to create a bike with 3D printed titanium frame. The bike is called Solid and can connect to a smart phone App: My Bike. This App alarms a user when a light needs replacement and if something gets wrong with one’s brakes. There is also software called Discover My City, which has a series of routes through Portland’s most trendy neighborhoods, with suggestions, about where to eat and shop.

Nevertheless, the idea with cycling is that you need to focus on the road and not on your smart phone. This bike therefore uses integrated (整合的) feedback on handlebars. Those handlebars tell a user when to turn, as they will buzz(嗡嗡叫) when a turn appears. As you are getting closer, they will buzz more frequently. And then there is the possibility to control your light via built-in sensors and change gears(齿轮) by pressing an electronic button.

Although the bicycle looks highly interesting and can be seen as a piece of art for the designing world, we don’t know if we would like our bike to have an automatic buzz when we are approaching a turn. On the other side, it could add some extra safety to traffic in general. Whether you like the bike or not, you have to admit the Portland-based studio brings the concept of urban biking to a whole new level.
