I've been pondering how to put this all together in one article, and am tired of these sitting in my writing queue. As such, this will be a pretty course overview.

Link - A fuel-cell powered three-wheel self-balancing "motorcycle". It appears this is only a concept vehicle and won't be sold any time soon. Nor does there even appear to be a prototype yet.

Link - A motorcycle with a wide two-wheel front end. Tilt-assisted steering enhances performance and safety. As-pictured, it appears to be for off-road use only. It's scheduled for release in Summer 2007.

Link - A 3-wheeled car. Non-hybrid. Tilt steering. Computer-enhanced suspension. It looks like this won't make it to market, at least in its current incarnation.

Link - A 3-wheeled scooter.

Link - A 3-wheeled motorcycle. Electric motor in the rear wheel.

Link - A 3-wheeled hybrid sports car. Over-powered gas engine, plus an electric motor in each wheel.

Link - 3-wheeled electric trike. The battery and motor are essentially invisible. Very cool design. Runs at 10mph for 4 hours.
