After the popularity of three-wheelers is rising, started by Piaggio MP3, Gilero Fuoco and Vectrix, a French scooter importer Sidam try to enter the market by building another type of three-wheel scooter. But this time, instead of putting two wheels at the front, they decided to put the two wheels at the rear of the vehicle. Kinda remind me of Thai Tuk Tuk, but Xnovo concept is somehow some crossover between a minivan and Thai Tuk Tuk.

The design sketches seem to suggest that both rear wheels will be belt driven in the 500cc Piaggio-engined petrol version – although hybrid and fully electric versions are also on the cards, the latter featuring twin electric motors, one in each wheel hub. The luggage angle is definately a big part of the concept fot Sidam.

We’ll wait to learn more as the Xnovo moves towards a launch date rumoured to be late 2008. Price is expected to be around ?8000 for the 500cc model.

I’m a little bit confused with this motor design, where do I sit ? This renovation concept by Confederate Motor Company uses minimal machine, using the fewest pieces, moving parts and systems to accomplish its dynamic mission. The word “Renovation” itself means rebirth, which also represent the rebirth of their headquarters company after destroyed by Hurricane Katrina. The Driving concept was the creation of a conceptually flexible foundation to allow a place for growth and further iteration; a utilitarian modular flexible foundation.

Conceived by the leader of our conceptual design team, Mr. Ed Jacobs, the motorcycle is at once primitive, bohemian, and yet highly technical. Renovatio is un-compromised, light weight, possesses enormous torque, is capable of extreme performance, yet has maximum real world streetable active safety. It is graceful in motion, yet potentially brutal. It exudes inner beauty through absolute follow through of truth of concept. Renovatio has great proportions, holistic brand gestalt, is original, impactful, alluring and elegant

The Tomahawk is a Viper V-10 based motorcycle, a 500 horsepower engine with four wheels beneath it. The engine breathes through twin throttle bodies mounted right up front. The Tomahawk concept is an awesome-sounding machine. Clouds of blue smoke vied for attention with the throaty rumble of the mighty V-10, and hitting the gas visibly opened the twin throttle body blades up front where the headlight would normally be. Though deeper and more rumbling than most motorcycles, it did not seem to be louder overall – just deeper and less shrill.

The Dodge Tomahawk can reach 60 miles an hour in about 2.5 seconds, and has a theoretical top speed of nearly 400 mph. Each pair of wheels is separated by a few inches and each wheel has an independent suspension. Bernhard said four wheels were necessary to handle the power from the engine.
