The Ecomobile is a cabin motorcycle produced by Peraves AG, manufactured in Winterthur, Switzerland since 1984.
Since Peraves wanted to avoid confusion with the eco-movement, the "OEkoMobIL" in "Ecomobile" was renamed "ECO" (internal name W18 K5).
In 2006, the MonoTracer was released, using BMW K 1200 RS engines; individual specimens with turbocharging and up to 190 hp (140 kW) are said to have reached a top speed of 315 km/h (196 mph).
[3] In 2010, the two prototypes of the MonoTracers MTE (also called X-Tracer) won the $2.5 million X-Prize with far the best efficiency of > 200 mpg-e equivalent consumption 1.1 L/100 km (260 mpg‑imp; 210 mpg‑US).
From 2009, vehicle production had been partly outsourced to the joint venture Bohema Mobil and Peraves CZ in Brno-Medlanky (Czech Republic).
To make the closed cab practical, hinged support wheels are mounted on both sides.
The retracted support wheels catch the fall softly and the vehicle takes no damage.
