The Trikke ( ) is a three wheeled scooter-like vehicle designed and marketed by Trikke Tech Inc. The patented cambering mechanism allows the rider to propel this chain-less and pedal-less human-powered vehicle without ever touching foot to ground. The design provides a stable 3-point platform that lets riders lean into the turns while all three wheels remain in contact with the ground. The front wheel can be turned left and right using the handlebars, with the axis of rotation offset towards the front of the wheel. The rear wheels are connected to independent arms and are fixed to face directly forward. The independent arms are almost touching at the front end, and are around apart at the rear end. The rider stands on the two foot platforms above the rear wheels. The mechanism that joins the independent arms and the front wheel/handlebars structure allows all three wheels to remain touching the ground when the handlebars are leaned to the left or right. The handlebars have two brake levers that control the brakes on the left and right rear wheels independently (although they are always both applied by the rider at the same time). A Trikke is propelled using a motion that moves the vehicle along a curved S shaped path. The rider moves the vehicle from side to side at a rough cadence of one turn per second. Each turn requires the rider to turn the handlebars in the direction of the turn, lean the front structure towards the side they are turning, move their body weight toward the side they are turning, and push out slightly with the foot at the outside of the turn. The weight of the rider during a turn (or “carve”) is placed mainly on the foot at the outside of the turn. The inside foot will support very little weight and the rider will often lift the heel of this foot during the turn. There are many variations on the Trikke riding technique as riders place different emphasis on the elements of the movement. The resulting motion is similar to slalom skiing. The motion also has similarities to the tic-tac move on a skateboard. A Trikke can be propelled without need to push off with the foot. Using the carving motion, a Trikke can achieve speeds of almost , but more often cruise at around . A Trikke can be ridden uphill, albeit at a reduced speed. ==History== The Trikke was invented by Brazilian born engineer Gildo Beleski circa 1988. He had built a three wheeled scooter for riding downhill and discovered that once reaching the bottom of the hill, the scooter would continue further if he turned it left and right. He enhanced this concept and designed the Trikke cambering joint that is the central component of the vehicle. Gildo established Trikke Tech in California, USA, in 2000. He formed a partnership with John Simpson, now Trikke Tech president, and they launched the Trikke to market in 2002. ''TIME'' news magazine named the Trikke one of the best inventions of 2002.〔(Time Magazine Best Inventions (2002) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trikke」の詳細全文を読む スポンサード リンク
