Trailcart

World's First Pedal-Powered 4WD Off-Road Vehicle

독일의 한 청년인  'Frank Fraune'에 의해 발명, 디자인된 세계 최초의 4WD Off-Road용 4륜 자전거(?)입니다.

페달과 4개의 휠, 프레임이 강화됨으로써 오프로드에도 주행이 가능하게 한 290Nm의 토크의 힘(torque:물체에 작용하여 물체를 회전시키는 원인이 되는 물리량으로서 비틀림모멘트라고도 한다.)으로 산악이나 바위지대의 험난한 환경에서도 주행이 가능한 세계 최초의 오프로드용 4륜 자전거입니다.

It seems like something that would have been invented before, and by red-blooded Americans for whom off-roading is a way of life, but the Trailcart, according to TreeHugger, is the world's "first pedal-powered four-wheel-drive off-road vehicle," and it was invented by a clever German fellow named Frank Fraune.

From a technical point of view, the Trailcart is like a hybrid mountain bike and four wheeler.

It's got permanent four-wheel-drive and is powered by roughly 290Nm of torque. In terms of conquering rockey terrain, it has 400mm of axle displacement. TreeHugger adds that it has a "double-action mechanical hydraulic braking system" and a Shimano Nexus 8 shifter coopted from the cycling world. The developers are trying to keep the weight at 50kg or less, in order to be transportable on automobile bike racks.

At the moment Trailcart is getting some serious investment from some heavy hitters, including Land Rover, and speaking of Land Rover, the little four-wheeler is involved in testing at Land Rover's "obstacle park" in Wülfrath, Germany. I really really want to try one of these out. There's no word on how much exertion is required to get that thing really moving, but if it takes any kind of physical strain at all, chances are it'll never make it to America.
