Both bikes use a similar power train, a hydrogen fuel cell / electric hybrid. Basically, the fuel cell produces electricity, which provides motivation and recharges the battery. When stronger acceleration is needed, the batteries — located in the belly pan — chip in. It's all completely seamless and silent in action and there's no gears or clutch, so the experience is a combination of the tall and narrow riding position of a dirt bike with the controls and power of a scooter. That might sound a bit boring, but the light weight and ease of use make the ideal combination for an approachable urban commuter.

While the ENV used high-end mountain bike components and topped out at wobbly 45mph, the Crosscage should make enough power to reach 60mph+ and a uses normal motorcycle suspension, wheels and tires, so expect a more competent and usable riding experience.

Before partnering with Suzuki, Intelligent Energy planed on selling the ENV in cosmopolitan, congested cities like London, Paris, Tokyo and New York. They'd overcome the lack of a hydrogen infrastructure with mobile filling stations in those areas - think guy in a pickup with some bottles of gas - and market their home natural gas / hydrogen conversion system as a permanent fuel source. If Suzuki moves ahead with Crosscage production, expect a similar strategy. [via Hell For Leather]
